The present invention relates to flavored adhesive (adhesive) of the composition, which, among other things, can be applied as a paste-like Wallpaper glue.
More specifically, the invention relates to adhesive compositions in the form of powder or granules, which the consumer can mix with water to get ready to use adhesive, in particular, ready-to-use paste adhesive for Wallpaper. According to one embodiment of the invention, the powder or the granules are in the form of a packaged commercial product.
Pasty glue for Wallpaper, usually sold in the form of powder or granules Packed in the form of a commercial product, which is mixed or blended ("prepared") to the consumer with water immediately before use, after which it is ready or ready for use. In addition to one or more main components (components)that are suitable for use in paste-like glue for Wallpaper or as a paste-like adhesive, such as potato starch, derivatives of cellulose or PVA powders, these powders may also contain additional components that are suitable for paste-like Wallpaper glue, such as preservatives. Such well-known (powders for -), paste adhesives for Wallpaper, for example, sold by the Applicant under the trade mark of the paste-like adhesive for Wallpaper FOBY ®".
The disadvantage of these known commercial products is that they can unpleasant smell during application. In particular, the well-known compositions are characterized by the typical smell of glue", which is mainly caused by the presence of major components and/or preservatives. An additional factor is that when (re) pasting of walls in older buildings can also emitted an unpleasant odor that arises from the paper (still) on the wall, and/or from layers of glue and/or glued layers (still) on the wall. In addition, unpleasant odors of this type can linger for a long time after application (i.e. within the (few) days after hanging Wallpapers).
In principle, the problem of the unpleasant odor of well-known compositions can be solved by including such a composition flavouring substance (odorant), the purpose of which is to mask or eliminate the smell of glue. However, it was found that, in practice, this solution is insufficient, in particular because of the composition in the form of packaged commercial products are usually stored (kept) in a long (long) period prior to their application. It was found that with this solution the main part of flavouring substances vswobogdataya composition during such storage, resulting flavouring substance not only released in the warehouse or in the store, which is undesirable, but in addition, the composition also almost losing (too lose) required the smell (odor intensity) to the time when it will be used/prepared by the consumer. Therefore, the inclusion of fragrances or perfumes, as such, in the famous pasty composition for Wallpaper leads to a product that is too short "shelf life"to be suitable for use as a commercial product.
In JP 01225644 described liquid adhesive composition containing an adhesive, a cyclodextrin and a flavouring substance. Such a composition is inconvenient that flavouring substance will quickly be released, because the cyclodextrin is in contact with water. Therefore, this part will not be able to be stored for a long period without appreciable loss of smell. If the composition, however, will be stored for a long period, he almost loses the intensity of the desired smell. Therefore, this composition is not suitable for use as a commercial product.
The purpose of the invention is to provide a solution to the aforementioned problems.
In particular, the purpose of the invention is to provide a composition for the manufacture on what lebialem pasty glue for Wallpaper, that is, by mixing with water, which, on the one hand, does not have the drawback of unpleasant odor during application and, on the other hand, is suitable for sale as a packaged commercial product and which, in this context, in particular, can be stored for a long period without loss of smell (odor intensity).
According to the invention this goal is achieved by the use in the dry, in particular in powder, compositions for the preparation of consumer pasty Wallpaper glue to at least one aromatic component that releases its scent (good for consumers) only when the composition comes into contact with water, i.e. when preparing the consumer.
In particular, according to the invention it was found that such a suitable composition can be achieved by applying the composition, known as such, for the preparation of consumer pasty Wallpaper glue to at least one aromatic component, which contains at least one flavouring substance and at least one carrier; flavouring substance in the specified aromatic component is connected and/or forms a complex with the carrier so that the substance is essentially released from the aromatic component, only when specified the flavouring component comes into contact with water, that is, during the preparation of a pasty composition for adhesion of the Wallpaper. Flavouring component of this type will (also) be referred to below as "component, releasing flavouring substance". Under flavouring substance understand any aromatic substance, or composition, including odorants.
According to the invention in that the releasing flavouring substance component as a carrier can be used, in particular, cyclodextrins, derivatives of cyclodextrins and/or similar compounds. Commercially available a number of compositions based on cyclodextrins and aromatic substances, which are suitable for use in the invention as releasing the smell of a component, in particular, for use in detergents and/or cleaners.
Therefore, in the first aspect of the invention relates to adhesive (adhesive) of the composition in dry form, such as the form of powder or granules, intended in particular for use in or as a paste-like Wallpaper glue, which contains:
the adhesive (glue);
releasing flavouring substance component that contains at least one flavouring substance and at least one media device.
The adhesive composition according to the invention is suitable for mixing/paramasivan the I water, performed by the consumer, with the formation of the ready-to-use (water) compositions.
The adhesive composition according to the invention is intended in particular for use as a paste-like Wallpaper glue and in this context may be the so-called "normal" pasty glue, so-called "special" pasty glue or specific pasty glue. These terms and pasty adhesives of this type are well-known experts in this field. Pasty adhesives for Wallpaper also often sold as "normal pasty glue or paste special glue.
Used in the component, releasing the smell, at least one flavouring substance is, as a rule, connected and/or linked in a complex that is enclosed, encapsulated, embedded or otherwise physically connected to and/or physically connected to the media, and in particular, connected and/or linked in a complex so that the flavouring substance is essentially released from the component, releasing aromatic substance, only when the latter comes into contact with water, i.e. during cooking by the consumer adhesive composition for the formation of a ready the use of aqueous adhesive composition.
Flavouring substance used in visuo olausen flavouring substance component, can be any aromatic substance, known as such, or any mixture of two or more substances, which is pleasant for the consumer smell and is suitable for use in adhesive compositions. In this context, flavouring substance, in particular, such that when it is used in the conventional amounts, it is able to eliminate and/or mask the unpleasant smell of glue (major components) of the adhesive compositions.
Thus, it is possible to apply, for example, is known as such flavouring substances and/or commercially available aromatic substances, such as substances with a pine smell, the smell of vanilla, lemon scent, the smell of citrus; or a suitable mixture of two or more substances. You can also use commercially available mixture of aromatic substances, such as, for example, a mixture referred to as mixtures with spring smell" or "summer scent". In this context, flavouring substances are, in particular, be selected based on the desired odor of the final product.
The media component, releasing the aromatic substance can be any - preferably organic and/or polymer - a substance or compound that is suitable for use in adhesives (glues) and can be used to control the release of flavouring substances which, so that the flavouring substance essentially frees the specified media only when the component releasing flavouring substance comes into contact with water. Substances or compounds used as the carrier, are, in particular, substances or compounds that are capable of this) include, encapsulate or embed in yourself and/or capable of binding flavouring substance other way (physically), and examples of suitable substances or compounds known to specialists in this field.
Especially suitable are cyclodextrins, derivatives of cyclodextrins and their mixtures, such as natural and/or synthetic α-, βand/or γ-cyclodextrin and methylated, acetylated, or other derivatives thereof. A number of suitable cyclodextrine derivatives, for example, marketed by Wacker-Chemie GmbH under the trade names CAVAMAX®and CAVASOL®.
Releasing the smell of components used in the invention typically are prepared separately, that is, before they are added to the pasty composition for Wallpaper. Cooking can in General be made by mixing one or more flavoring agents and one or more carriers, that is, in the right quantities/relationship and thus that flavouring what substances are or other suitable image embedded in the media.
A number of such compositions, based on the complex of cyclodextrin and fragrances, also commercially available, and they are not necessary can also be used in the invention as components, releasing aromatic substance. Such compositions currently used, for example, cleaners and detergents, and in particular, in the cleaner for fabrics and washing powders.
The adhesive, which is used as a component in compositions according to the invention, can be any component known as such for adhesives and in particular, to a pasty glue or a mixture of two or more such components. Suitable examples of such components are obvious to experts in the field and include, for example (without limitation to), different types of starch such as potato starch, or starch derivatives of this type; cellulose and derivatives of cellulose, such as carboxymethylcellulose or methylcellulose; or powders of polyvinyl acetate (PVA); or a suitable combination of two or more such substances. Such components, for example, commercially available under the trademarks Solvitose and Perfectarnyl (both from Avebe), Vinnapas (Wacker Chemie), Walocel (Wolff Walrode), Gabrosa (Akzo Nobel) or Tyiose (Clariant).
For example, applied the main component may contain, for example, one or more of the following component is in the specified amounts (based on the total mass of the main component):
The main component
|Potato starch||0-100% (wt./wt.)|
|The methylcellulose||0-50% (wt./wt.)|
|Powder of polyvinyl acetate||0-25% (wt./wt.)|
|for preparation of total 100%(wt/wt)||the main component.|
In addition to the adhesive and the component, releasing the smell, pasty composition for adhesion of the Wallpaper according to the invention may also optionally contain one or more components, known as such, for paste-like Wallpaper glue, such as preservatives.
In General, a pasty composition for adhesion of the Wallpaper according to the invention can be obtained by mixing the components of the adhesive, one or more additional components and component, releasing aromatic substance with each other in suitable quantities. Typically, during this procedure, first mix the primary and secondary components for the formation of the main paste composition for bonding Wallpaper, known as such, then, usually at the final stage or on one of the final stages of the preparation of the final adhesive the composition is according to the invention add a component, releasing flavouring substance.
In this way, the adhesive and optional additional components generally used in quantities known as such, which, as a rule, lie in the interval (based on the "basic pasty composition for adhesion of the Wallpaper without the component, releasing aromatic substance):
The main paste composition for bonding Wallpaper
|The main component||0-100% (wt./wt.)|
|Other components||0-0,5% (wt./wt.)|
|for preparation of total 100%(wt./wt.)||the main paste composition for adhesion of the Wallpaper.|
Then to the main paste composition for bonding Wallpaper add component, releasing aromatic substance in a suitable amount, i.e. the amount that is sufficient to mask/eliminate unpleasant smell (components) of the main paste composition for adhesion of the Wallpaper during application of the adhesive composition.
Such amounts generally are between 0.5 and 5% (wt./wt.) (such as about 2.5% (wt./wt.)) based on the total weight of the composition, depending on the component, releasing aromatizer the substance abuser, and additional components of the adhesive.
The mixture of various components of the composition for adhesion of the Wallpaper, as a rule, have a known essentially the way, for example, by dry mixing the components on the horizontal ribbon or paddle mixer, or mixer with a vertical auger.
In this way the composition according to the invention receive in dry form, such as powder or granules, which essentially has not (don't) smell or only a slight odor used fragrances, but after mixing with water have a smell used flavouring substances, i.e. instead of the typical smell of glue. In addition, the composition can favorably be stored for a long period, that is from a few months up to several years essentially without losing its smell (odor intensity) for the final application.
Specialists in this field from the above it will be clear that the adhesive/paste-like composition for the Wallpaper according to the invention can also be obtained by adding one or more components, releasing fragrances, as described above, to essentially known, adhesive/paste-like composition for Wallpaper in dry form, and the thus obtained composition also fall within the scope of the invention.
Therefore, it is in one aspect the invention relates to the use, at least one component, releasing flavouring substance (as described above), for flavoring adhesive compositions, in particular for flavoring adhesive composition, as described here, and more preferably, for flavoring paste-like composition for bonding Wallpaper such compositions in dry form, designed for mixing in water by the consumer, as described above. In this context, the use of at least one component, releasing aromatic substance, usually in quantities specified above.
The adhesive/paste for gluing of wall-paper in the dry form according to the invention are sold, usually in the form of a packaged commercial product, and in particular, in the form of powder or granule(s) Packed (Packed in a box, jar, bag, tin can or other suitable container which, for example, can contain a single number pasty glue for Wallpaper according to the invention, such as, for example, 125 g for normal pasty glue, or 200 g or 250 g for special pasty glue, and up to quantities of 500 g or more. Such (Packed) commercial products constitute another aspect of the invention. In addition, the invention also includes bulk packaging adhesive composition according to the invention, voltage is emer, contains 5, 10 or 15 kg
Then powder or granules can be mixed by the user with water, i.e. in quantities/relations, which are essentially known and/or are appropriate (for example, 125 g of powder per 6 liters of water for normal pasty glue and 200 g of powder per 4 liters of water for special pasty glue), and usually immediately before use (component, releasing aromatic substance) of the adhesive composition comes into contact with water, and one or more flavouring substances released from the component, releasing the smell, and thus released from/through the adhesive composition.
As a consequence, the application of the adhesive/paste Wallpaper glue according to the invention will not be accompanied by the typical smell of the adhesive compositions known to date. Fragrances will also be able to positively mask/prevent any unpleasant odour arising from Wallpaper already on the wall, and/or layers that are on the wall, such as the old layer of glue or glued layer.
Therefore in another aspect the invention relates to the production of aqueous adhesive compositions, and in particular, water pasty glue for Wallpaper, comprising mixing a pasty composition for adhesion of the Wallpaper according invented the Yu with a suitable amount of water for the formation of a ready-to-use adhesive composition.
The invention is described above, in particular, with reference to (water) adhesives based on the above-mentioned main components, and more preferably, with reference to the paste-like adhesive for Wallpaper. However, it is assumed that the invention may find wider application, such as, in General, the adhesives in dry form and, in particular, adhesives, water-based and/or (other) compositions based on above-mentioned main components, which are intended for dilution or mixing with water, regardless of any future intended use of them.
In addition, the invention includes the introduction/ application described here, components, releasing the smell of, for example, in the above-mentioned basic components (or their mixtures), when these key components are supplied and/or sold as raw material for production of adhesive compositions according to the invention.
The use of the above-described components, releasing flavouring substance in these compositions, and the compositions thus obtained, is another aspect of the invention.
The following non-limiting example illustrates the invention in more detail.
