SYSTEM FOR joining GLASS WITH STRUCTURE

The technical field to which the invention relates

The present invention relates to compositions used to produce glass or plastic, coated with abrasion resistant surface for bonding with the polyurethane adhesive. In another embodiment, the present invention relates to systems containing composition used to produce glass or plastic, covered with abrasion-resistant coating, to connect with polyurethane adhesives and polyurethane adhesives. The present invention also relates to a method of connection of glass or plastic, covered with abrasion-resistant coating, in a structure such as a building or vehicle, using the system of the present invention.

The level of technology

Installation of glass, as a rule, is a three-stage process. First, the glass is applied to a transparent silane primer to clean and prepare the surface for bonding. Secondly, on top of the transparent primer then apply the primer, which mainly represents the dispersion of carbon black, which also contains a compound having a silane and/or isocyanate functional groups, often called "masked priming". In-tert what them on primed glass, which is then installed in the structure, apply the adhesive. Cm. U.S. patent No. 5370905 included here as a reference. Masking primer may stain the surface of the structure or vehicle in which the masking primer may drip during installation. U.S. patent No. 5363944 describes a single-stage system primer. The primer contains an aqueous solution of a primer containing a silane binding agent, which is used to facilitate adhesion of the polymer to the porous inorganic substrate, such as metal or glass. Silane binding agent has a functional amino or mercaptopropyl, which can interact with the functional groups of the polymer, and also has one or more hydrolyzable groups, which interact with the free hydroxyl groups on the surface of the substrate. This system requires a long drying times before can be applied adhesive. For many industrial operations such long drying times are unacceptable. This is especially true for automotive Assembly plants, where each operation should be completed in a short period of time.

Yao et al. U.S. patent No. 6511752 describes a method of bonding adhesive based on polyurethane with a substrate, which includes NAS is safety on the substrate an aqueous solution of primers, which contains water, aminosidine titanium and preferably epoxysilane having at least one apachegroup and at least two alkoxygroup. After that, on the surface, primed, apply polyurethane adhesive. The reaction product is formed from the primer and polyurethane.

For the system of primer and adhesive was commercially viable, this system should provide the connection with a long service life. "The connection with a long service life" means that the adhesive holds the window in the structure during the period of several years. Since the structure, which is generally attached to window glass or plastic, coated with abrasion resistant coating is retained for a considerable number of years, it is expected that the connection holding the glass or plastic coated in the structure will withstand a considerable number of years. What is needed is a system that connects coated glass or plastic structure that does not require masking primer, which provides long-lasting adhesion and which does not require long drying times between application of the primer and adhesive application. In addition, what is needed is a system that makes it possible for durable adhesion of adhesives on on the Ergneti substrate.

May be preferential addition of any plasticizer to the reaction mixture to obtain a prepolymer containing isocyanate, so that the mixture was easy to mix, and it would have been easy to manipulate. Alternatively, the plasticizer may be added during mixing of all components. After preparation of the composition of the adhesive it is Packed in an appropriate container, so that it is protected from atmospheric moisture. Contact with atmospheric humidity could lead to premature cross-linking of the polyurethane prepolymer containing isocyanate groups.

The composition is transparent primer is prepared by bringing into contact silanes and titanates in a solvent and mixing with formation of a transparent solution.

How great the ILO the method of connection of glass, plastic coated or Windows substrate comprises bringing into contact of the composition of the transparent primer of the present invention with the surface of the glass or plastic coated and allow the solvent composition transparent primer to evaporate. After that, an appropriate adhesive is applied to the surface of glass or plastic coated, along that part of the glass or plastic coated, which must be connected to the structure. After that, the adhesive comes into contact with the second substrate so that the adhesive is located between the glass and the second substrate. The adhesive allow for curing, with the formation of durable connection between glass or plastic coating and substrate. In some embodiments, the implementation of glass or transparent plastic has a matte coating along the perimeter of the glass or transparent plastic. It is commonly referred to as sintered ceramics. For glass coating is an inorganic enamel. Transparent primer improves the ability of the described systems adhesives connection with such coatings.

Robots are suitable for this operation are, for example, M710I available from Fariuc Robotics America, Rochester Hills, Michigan, used in conjunction with an automatic applicator for distributing primers supplied by Nordson Corporation, Amherst, Ohio. Primer should be applied in such a way that the drying time after application of the primer is at least from about 8 to about 15 seconds. The adhesive is applied at least 20 seconds after application of the adhesive. The system of the present invention can be used to join glass or plastic, covered with abrasion-resistant coating, with other substrates, such as metal or plastic. Plastic coated abrasion resistant coating may be any plastic, which is transparent, such as polycarbonate, acrylic, hydrogenated polystyrene or block copolymers, hydrogenated styrene and a conjugated diene, having a styrene content greater than 50 percent. The coating may include any coating that is resistant to abrasion, such as polysiloxane coating. Preferably pok the eve ENT has a pigment additive, blocking ultraviolet light. Preferably a glass or plastic window has an opaque coating, located in the area that you want to get in contact with the adhesive, to block UV light which can reach the adhesive.

Minimum time between application of a transparent primer and adhesive application represents the time required for the solvent of the clear primer is gone. In some embodiments, the implementation of the composition of the adhesive can be applied in a location different from the location of application of transparent primer, for example in another part of the plant or at another plant. In addition, plants can be many miles from each other, for example hundreds or thousands of miles. The adhesive composition can be applied much later than transparent primer. In some embodiments, the implementation of time between the application of a transparent primer and applying the adhesive composition may be about 5 days or more, or even 30 days or more. The period of time between the application of a transparent primer and applying the composition of the adhesive may be approximately 90 days or less, and preferably is about 60 days or less.

If a transparent primer contains a component that evaporates, then the method may further include the formation stage of an infrared image window, as component evaporates, to specify the scope of application of transparent primer. If a transparent primer contains a component that's fluorescent when illuminated with UV light, then the method may further include stage lighting window UV light to indicate the area of application transparent primer. These methods can be implemented as described in the jointly owned by the publication of U.S. patent Allam et al., 2003/0232152 and application of PCT international patent application WO03/106579, registered on June 11, 2003, included here as a reference.

The system of the present invention is used to connect together the porous and non-porous substrates. The adhesive composition is applied on a substrate, and the adhesive on the first substrate then comes into contact with the second substrate. After that, the adhesive is exposed to conditions for curing. In a preferred embodiment, one of the substrates is with the battle of glass or plastic coated, and the other substrate is a plastic, metal, fiberglass or composite substrate, which optionally can be painted. This method is particularly effective for substrates coated with acid-resistant paint. Typically, primers and adhesives are applied when the ambient temperature in the presence of atmospheric moisture. The influence of atmospheric moisture is sufficient to cause curing of the adhesive. Curing can be accelerated by application of heat to cure the adhesive by means of convection heating, or microwave heating.

Specific embodiments of the invention

The following examples are included here only for illustrative purposes and are not intended to limit the scope of the present invention. Unless otherwise indicated, all parts and percentages are mass

Preparation of transparent primers

The medicines given or fractional solution, or in percentage relative to solid products, and get them by simply mixing the appropriate amounts of the desired material. Primer receive by adding a solvent in a pre-dried glass bottle. Each silane is added to the bottle and the bottle shaken for 2 minutes on a shaker. Finally, add the titanate and the entire mixture is shaken for 3 minutes.

Experiments on adhesion is carried out on three ceramic enamels on the cut surface of the glass sample. Two of them, namely containing bismuth and zinc powder ceramics (sintered ceramics 1) and containing bismuth and zinc powder ceramics, optionally containing lithium and sulfur (powder ceramics 2)use on gotom glass. The third is a ceramics powder containing bismuth and zinc (powder ceramics 3), which is used on curved glass. Each of these three ceramic enamel is available from Ferro Corporation. All the cut glass samples are used, as they are obtained without any additional purification or pre-treatment other than the application of the specified transparent cloth.

The composition of the transparent primer is applied through nasysheniya solution and thin wet coating on the surface of the ceramic enamel. Twenty seconds after the application of a transparent primer is applied to the adhesive layer width of 8 mm and 6-8 mm thick, down the length of the substrate. To allow adhesive to cure before the examination within 7 days at 23°C and 50% RH (relative humidity). Study of adhesion is a modified study of exfoliation, called the study Quick Knife Adhesion (QKA). In this study, the interface of the adhesive/substrate interface was estimated using a sharp knife, when the adhesive is drawn. The results are listed as a percentage of gaps bonding (gap inside urethane adhesive), the desired result is 100 percent CF (breaks gluing). An alternative mode of the gap is a gap of adhesion, which is a disconnection of the adhesive with the surface of the substrate. In addition to the initial adhesion of additional samples pass through an experiment in longevity. Upon receipt of samples and curing for seven days, as described above, the sample is placed in a water bath and maintained at 90°C. Upon completion of the specified time, the sample is removed from the water bath, leave at least 15 minutes, and then explore through research QKA. Long-term durability is expressed as the number of days required for the loss of 00 percent CF, that is, when the adhesive demonstrates a certain gap adhesion. The adhesive 1 is an adhesive prepared from a prepolymer with isocyanate end groups, grafted silane, a plasticizer, carbon black, simple 2,2-demoralization the ether carboxylate dimethylurea and fosfatnym antioxidant.

Examples 13 and 14 lead performance primers, which are produced without Milanovich of adhesion promoters. The adhesive 1 is applied to each of examples 20 seconds after the glass is applied to a transparent wiping, and the results show that the adhesion is significantly improved by combining a mixture of silane and titanium compounds.

Comparison of examples 10, 13 and 14 shows the benefits of combining the titanate/silane. Adhesion of example 10, the combination of Tyzor® TOT, and a mixture of silane, demonstrates 100 percent CF. Remove mixture of silane reduces the working characteristics of the adhesive to 60 percent CF for example 13 and to less than 90 percent CF for example 14. The connection replacement titanium compound, zirconium also reduces adhesion. Two drugs, prepared with compounds of zirconium, examples 11 and 12, you lose 100 percent of rupture of adhesion during the initial research QKA. Break adhesion (AF) means the destruction of the adhesive compounds adhesive surface of the substrate.

Examples 1-3 and 15-23 using mercaptopropionylglycine, N-amino-ethyl-3-aminopropyl hematoxilin and bis-(3-triethoxysilylpropyl)aminosilane, combined with the titanate Tyzor® OGT demonstrate 100 percent gap adhesion during the initial experiments with adhesion. Example 24, cooked without titanate Tyzor® OGT and with a mixture of silane 1:1:1, reaches a strong initial adhesion with each of the three enamels. However, the durability of this system is less than desired.

The combined organic compounds of titanium with a mixture of silanes demonstrates excellent adhesion. Comparison of examples 1, 2, 3, and 24 shows improved durability when Tyzor® OGT used together with a mixture of silane 1:1:1. When the titanate Tyzor® OGT removed from the drug, you receive a complete loss of break adhesion to each of the three ceramic powder in less than one day in a water bath. The titanate Tyzor® OGT, regardless of level, improves the durability of adhesion for each of the ceramic enamels. The operating characteristic of durability can be obtained when the drug has a higher percentage of mercaptoethane. This is illustrated by a comparison of examples 18, 20 and 23. Durability is improved when the number of aminosilane towards mercaptoethane decreases.

Compare two adhesives, one without packaging stabilizer and packaging of the stabilizer. The first adhesive is an adhesive 1, as described above. The second contained the adhesive is an ADH is the Ziv 1 sitosterolemia based on the difficulty amine, sold under the trade name and designation Tinuvin 765, and the ultraviolet light absorber Tinuvin 571. The primer containing the primer of example 17, is applied by wiping the surface of the substrate with a coating of enamel, using gauze soaked in primer. The substrate used are powdered ceramics 1-3. To allow solvent to evaporate for 20 seconds and put the adhesives. The adhesive utverjdayut at 23°C, 50 percent relative humidity for 7 days. Samples exposed to conditions as described in SAE 1885, WOM atmospheric chamber during 2000 and 2500 hours, then the samples examined in accordance with the study of SAE 1885. The results are shown in table 4.

These data illustrate that the use of light and UV stabilizer in the adhesive improves long-term durability of the connection with the adhesive system.

Cut the samples stored at 35°C and at a relative humidity of 90 percent within a specified time. Adhesives A and B is applied on the cut samples in accordance with the study QKA described above. Then cut the samples with the adhesive applied is electroplated on the surface, utverjdayut within 7 days at 23°C and a relative humidity of 50 percent. During each period of time in the open state, one cut the sample examined in accordance with QKA after a period of initial curing. The second cut, the sample is treated, stored for 14 days at 100°C and a relative humidity of 100 percent. Adhesive A is an adhesive based on isocyanate and silane functional prepolymer. The adhesive B is an adhesive based on the isocyanate functional prepolymer.
