Problems solved by technology

Among the methods of adding materials other than glass, mobile phone film is a convenient and low-cost solution to improve the impact resistance of touch screen glass, but it has the following disadvantages: 1) It covers the anti-fingerprint agent coated on the surface of the mobile phone touch screen when it leaves the factory , so that the anti-fingerprint function of the touch screen is lost; 2) The sensitivity of the touch of the human finger is reduced; 3) One more cumbersome film application procedure weakens the consumer's ultimate experience of the product
[0004] Chinese patent CN108504184A discloses an anti-impact ink for glass and its application method. The anti-impact ink includes the following raw materials: photoinitiator, silicone modified acrylate, vinyl coupling agent, epoxy coupling agent, silicon Alcohol resin, tetrafunctional urethane acrylate and solvent, which not only improve the impact resistance of glass, but also the ink is easy to use, which is beneficial to popularization and implementation; however, the impact resistance of the glass impact ink is limited, the hardness is soft, and the coating The layer is easily scratched and yellowed, which is not conducive to the industrialization of the product

Abstract

The invention discloses an impact-resistant glass coating and a preparation method thereof. The impact-resistant glass coating comprises the following components in parts by weight: 20-30 parts of condensation type silicone resin, 2-10 parts of vinyl silicone resin, 1-5 parts of curing agent, 1-5 parts of adhesion promoter, 0.1-1 part of leveling agent and 55-65 parts of solvent; the impact-resistant glass coating prepared by this preparation method can not only improve the impact resistance of glass Increased by more than 80%, and the coating itself has high hardness, no yellowing, and has good high and low temperature resistance, weather resistance and water resistance.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an impact-resistant glass coating and a preparation method thereof. Background technique [0002] Glass is an important material with a wide range of applications ranging from construction, automotive, flat panel displays, wearable consumer electronics, to optical instruments, etc. In order to meet the requirements of use, it is usually necessary to improve the impact resistance of glass. It can be started from two aspects, tempering the glass itself or adding materials outside the glass. [0003] Taking mobile phone touch screen glass as an example, the current top brand is Corning Gorilla Glass of the United States, which adopts the method of chemically tempering the glass itself to make it have good impact resistance. Among the methods of adding materials other than glass, mobile phone film is a convenient and low-cost solution to improve the impact resistance of touch scre...
