The present invention relates to stable mixtures, including fillers, and more particularly to stable mixtures, comprising a filler and a thickener in selected combinations and concentrations for use in the preparation of paints and other target products.

In simultaneously considering patent applications US serial number 60/183655, 60/183656 and 60/247639 described semi-finished products and methods of preparation of paints of these semi-finished colors. One of the semi-finished colors, which is required for carrying out the invention is a mixture comprising at least one filler. Two other semi-finished colors can include either a pigment that gives the opacity or emulsion polymer binder. The key distinctive feature of the way in which for preparation of paints used semi paints based on the requirement that the semi-finished colors were compatible with each other so that they can be blended in different ratios to create at least one line of paint. Another key distinguishing feature is based on the requirement that the semi-finished paint, does it include filler, giving the hiding power of the pigment or binder emulsion polymer type, was so stable, that it is semi-paints can be prepared, be transported and stored without spoilage, including the manifestation of heterogeneity, syneresis, sedimentation, gelatinization and viscosity changes.

With regard to mixtures comprising a filler, their stability can be a serious problem. This is especially true when you consider that even the best technically available suspensions of fillers are defined (>2 vol.%, according to visual estimation) syneresis and the formation of sludge during storage, so before use they must intensively and for a considerable period of time to mix.

When creating the present invention was found a number of stable mixtures, including fillers and thickeners in specific combinations and concentrations, which, among other things, can be used as mixtures in the process of preparation of paints using semi paints or as a normal component in the coating or for another the final goal, which will include the use of fillers, including coatings substances for impregnating, printing inks, graphic arts, paper making, textile technology products, sealing compounds, mastics, adhesives, sealants, building materials and the tanning of leather.

All mixtures can be prepared by simple mixing of the components, for example, by means of paddle stirrers or shaking.

Occurring in the present description the term "stable" is used with reference to mixtures that satisfy all required parameters, defined according to the following tests after storage at a temperature of at least 120°C for at least 10 (ten) days.

1. The mixture exhibits less than 2% vol. synaeresis (according to the results of visual evaluation of the predecessor paint) (in this description referred to as "test 1 stability").

2. After the mixture is allowed to cool to room temperature (22 to 25° (C)but prior to mechanical shear stress, the viscosity of the mixture according to Brookfield (determined at a shear rate of 1.25 with-1is less than 100000 SP, preferably less than 50,000 CPs (in this description referred to as "test 2 stability").

3. After the mixture was allowed to cool to room temperature (22 to 25°C), and after exposure to mechanical shear force using propeller-type agitator is the ratio between the viscosity Brookfield (determined at a shear rate of 1.25 with1 after thermal aging and viscosity according to Brookfield (determined at a shear rate of 1.25 with-1) to thermal aging is not more than 3 (in this description referred to as "test 3 stability").

Technical filling suspensions are not tested 1 for stability, so before using them you need to mix, sometimes constantly. Mixture with high viscosity by Brookfield before shear processing, as described in the description of test 2 on stability, tend to gelatinization and resistance to expiration, resulting in their transfer using conventional equipment associated with the problems of a technological nature. The results of the test 3 stability serve as an indication that there are in the mixture during storage or has not occurred or will occur gel lattice structure, resistant to shear dilution (mixing).

In this case, the proposed three modes of mixing, which corresponds proposed by the present invention, the classification of mixtures on stability, namely the classification of those mixtures, which are:

(1) does not require any mechanical agitation or mixing of other forms in a typical period (at least 30 days) and conditions (high temperature, up to 140°F and low temperature, up to 25°) storage for in order to maintain stability (in the present description are called "stable, does not require mixing") (require mixing within 0% of the time storage);

(2) require periodic (or from time to time) mechanical mixing or mixing other forms for re-homogenization/destruction of any minimum or weak patterns formed at a typical time (at least 30 days) and conditions (high temperature, up to 140°F and low temperature, up to 25° (F) storage in order to maintain stability (in the present description are called "stable, requiring periodic mixing") (require mixing for >0% of the time storage); and

(3) require continuous mechanical agitation or mixing of other forms for re-homogenization/destruction of any significant patterns formed at a typical time (at least 30 days) and conditions (high temperature, up to 140°F and low temperature, up to 25° (F) storage in order to maintain stability (in the present description are called "stable, requiring constant stirring") (require mixing for >50% of the time of storage).

It should be noted that although stable, does not need stirring the mixture does not require any mechanical mixing or is remesiana other forms for to remain stable, the use of mechanical mixing or mixing other forms (either periodic or constant) does not exclude the applicability to this particular mixture of the definition of "stable mixture that does not require mixing". Similarly, it should be noted that, although stable, requiring periodic stirring the mixture requires only periodic mechanical agitation or mixing of other forms in order to remain stable, the use of continuous mechanical mixing or mixing other forms does not exclude applicability to this particular mixture of the definition of "stable mixture, requiring periodic mixing".

Mixing of the mixtures is not limited to any one type, it can be produced by using a blade mixer, recycling, shaking, grinding, rotation, bubbling, using ultrasound, pumping or any other means of bringing the mixture into motion.

The mixture of the present invention can be used as semi-finished paint systems using delayed differentiation of the product, as it is presented in patent applications US serial number 60/183655, 60/183656 and 60/247639, and to use instead of known mixtures of fillers, such as nab, niteline suspension, mixture to milling, dispersion dyes, paint, coating, etc.

The volume concentration of pigment (in this description referred to as GST) is a measure of how "rich composition binder". In the present description it is calculated by the following formula:

Volumetric content of dry substance (in the present description "OS") is the amount of dry pigment (pigment) plus the amount of dry fillers (fillers) plus the amount of dry binder substance (s). In the present description it is calculated by the following formula:

Binders bind the pigments and/or fillers, to provide the desired fluidity of the paint and determine the gloss and hardness of the final layer of paint. Binders selected for the semi-finished colors depend on the final destination of the finished paint. Binders acceptable for paints for exterior use, usually suitable for interior paints, but binders acceptable for interior paints, can be unacceptable for paints for exterior use.
