Background
Glass is an important material with a wide range of application markets, from construction, automotive, flat panel displays, wearable electronics, to optical instruments, and the like. In order to meet the requirements of use, the impact resistance of the glass is generally required to be improved. The glass can be tempered or materials can be added outside the glass from two aspects.
Taking mobile phone touch screen glass as an example, the current famous brand of the pioneer cogongrass is gorilla glass of corning corporation in the United states, and the method is to chemically toughen the glass so that the glass has good impact resistance.

In order to achieve the purpose, the invention adopts the following technical scheme:
an impact-resistant glass coating comprises the following components in parts by weight:
preferably, the condensed type silicone resin is one of T-type methyl silicone resin, D-type methyl silicone resin, T-type phenyl silicone resin, D-type phenyl silicone resin and D-type methyl phenyl silicone resin or a mixture of two or more of the T-type methyl silicone resin, the D-type methyl phenyl silicone resin and the D-type methyl phenyl silicone resin.
Preferably, the vinyl silicone resin is one or a mixture of two or more of methyl vinyl silicone resin, methyl phenyl vinyl silicone resin and methyl trifluoro propyl vinyl fluorosilicone resin.
Preferably, the curing agent is one or a mixture of more than two of benzophenone, 1-hydroxy-cyclohexyl-phenyl ketone, 2-hydroxy-2-methyl-1-phenyl-1-acetone, ethyl orthosilicate, dibutyltin dilaurate and n-butyl borate.
Preferably, the adhesion promoter is one of gamma-aminopropyltriethoxysilane, gamma- (methacryloyloxy) -propyltrimethoxysilane, gamma-mercaptopropyltriethoxysilane and gamma-mercaptopropyltrimethoxysilane or a mixture of more than two of the gamma-aminopropyltriethoxysilane, the gamma- (methacryloyloxy) -propyltrimethoxysilane and the gamma-mercaptopropyltrimethoxysilane.
Preferably, the leveling agent is one or a mixture of two or more of polyether modified organic silicon, polyester modified organic silicon, polydimethylsiloxane, fluorine modified acrylate and acrylate copolymer.
Preferably, the solvent is one or a mixture of more than two of ethyl acetate, butyl acetate, isopropanol, n-butanol, ethanol, ethylene glycol monobutyl ether and propylene glycol methyl ether.
A preparation method of an impact-resistant glass coating comprises the following steps:
s1, dissolving 20-30 parts by weight of condensed type silicone resin into half of the solvent, and magnetically stirring for 0.5-1.5 hours until the condensed type silicone resin is completely dissolved in the solvent; then sequentially adding 2-10 parts of vinyl silicone resin, 1-5 parts of adhesion promoter, 0.1-1 part of flatting agent and the other half of solvent, and magnetically stirring for 1.5-2.5 hours; after stirring, adding 1-5 parts of curing agent, and magnetically stirring for 0.2-0.8 hour to obtain the impact-resistant coating;
s2, spraying the impact-resistant coating obtained in the step S1 on the surface of glass by an automatic air spray gun, and controlling the film thickness of the coating to be 8-12 microns;
s3, placing the glass sprayed with the impact-resistant coating in the step S2 into a baking oven at 75-85 ℃ for pre-baking for 5-10 minutes; placing the pre-baked glass into an ultraviolet UV furnace for curing, wherein the ultraviolet energy is controlled at 500-700mJ/cm2(ii) a And then placing the glass subjected to ultraviolet curing into an oven at the temperature of 165-195 ℃, curing for 30-50 minutes, and cooling to room temperature to obtain the impact-resistant glass coating.
After the technical scheme is adopted, compared with the background technology, the invention has the following beneficial effects:
1. the invention relates to an organic silicon system, which adopts two main materials of highly branched (molecular structure highly cross-linked and branched) organic silicon resin (condensed type silicon resin) and silicon rubber (vinyl silicon resin) to prepare a transparent impact-resistant coating, and an interpenetrating spatial three-dimensional network structure can be formed between the two main materials. Highly branched silicone resins, which firstly have a very strong hardness; secondly, because the space of the molecular structure has structural defects and a large number of 'holes' exist at the branch points, when the system is impacted, the 'holes' can absorb a large amount of energy instantly, and the self deformation has a buffer effect on the generation and expansion of cracks, thereby improving the toughness of the system. On the other hand, since the silicone rubber is a linear elastic polymer material having a very low degree of crosslinking, it can further absorb external impact energy by its elastic deformation. When the external force is cancelled, the system returns to the original state, so that the system is kept intact, and the impact resistance effect is achieved. Under the synergistic effect of the two materials of the highly branched organic silicon resin and the silicon rubber, the toughness and the elasticity of the system are obviously improved, so that the glass has strong shock resistance and higher hardness.
2. In the preparation process of the impact-resistant glass coating, the condensed type silicon resin can be cured into a spatial network structure with a highly crosslinked and branched molecular structure through thermosetting; double bonds in silicone rubber (vinyl silicone resin) monomer molecules can be opened through Ultraviolet (UV) curing, and linear elastic high polymer materials with low crosslinking degree are polymerized among the molecules, so that the shock resistance of the system is realized.
3. The adhesion promoter added in the invention can improve and enhance the adhesive force between the coating and the glass substrate, and plays a role of a bridge between the substrate and the coating. In the molecular structure of the adhesion promoter, one end is a-Si-O-R group, and when meeting with trace water molecules in the air, the adhesion promoter is hydrolyzed to generate a-Si-OH group which can be subjected to condensation reaction with-OH hydroxyl on the surface of glass to form a firm-Si-O-Si chemical bond (covalent bond). The other end of the molecular structure of the adhesion promoter is-NH (amino), -SH (mercapto) or-OO-C (CH)3)＝CH2(allyl). One end is-NH (amino group), -SH (sulfhydryl group) which can be condensed with-OH hydroxyl group in the coating organic silicon resin to form firm chemical bond (covalent bond); -OO-C (CH)3)＝CH2The (allyl) groups are capable of undergoing UV polymerization with the double bonds of the silicone rubber in the silicone resin. Ensures that the coating does not fall off due to thermal expansion and cold contraction and is resistant to boiling, and improves the bonding strength of the coating and the glass substrate.
4. The organic silicon resin molecules adopted by the invention do not contain groups capable of yellowing, so that the risk of yellowing of the coating is avoided; the coating can obviously improve the shock resistance of the glass by more than 80 percent, the hardness is more than 2H, the yield of production is ensured, and the cost is reduced; the coating also has other characteristics of organic silicon, such as high and low temperature resistance (-55-250 ℃), weather resistance, water resistance and the like.

8. A method for preparing an impact-resistant glass coating according to any one of claims 1 to 7, comprising the steps of:
s1, dissolving 20-30 parts by weight of condensed type silicone resin into half of the solvent, and magnetically stirring for 0.5-1.5 hours until the condensed type silicone resin is completely dissolved in the solvent; then sequentially adding 2-10 parts of vinyl silicone resin, 1-5 parts of adhesion promoter, 0.1-1 part of flatting agent and the other half of solvent, and magnetically stirring for 1.5-2.5 hours; after stirring, adding 1-5 parts of curing agent, and magnetically stirring for 0.2-0.8 hour to obtain the impact-resistant coating;
s2, spraying the impact-resistant coating obtained in the step S1 on the surface of glass by an automatic air spray gun, and controlling the film thickness of the coating to be 8-12 microns;
s3, placing the glass sprayed with the impact-resistant coating in the step S2 into a baking oven at 75-85 ℃ for pre-baking for 5-10 minutes; placing the pre-baked glass into an ultraviolet UV furnace for curing, wherein the ultraviolet energy is controlled at 500-700mJ/cm2(ii) a And then putting the glass into an oven with the temperature of 165-195 ℃, curing for 30-50 minutes, and cooling to room temperature to obtain the impact-resistant glass coating.
