Preparation method of impact-resistant glass with coating

Abstract

The invention discloses a preparation method of impact-resistant glass with a coating. The coating comprises the following components in parts by weight: 20-30 parts of condensed silicon resin, 2-10 parts of vinyl silicon resin, 1-5 parts of a curing agent, 1-5 parts of an adhesion promoter, 0.1-1 part of a leveling agent and 55-65 parts of a solvent. A step-by-step spraying mode is adopted, an anti-impact coating is sprayed on a preheated glass base material, after ultraviolet curing and thermal curing, the coating is cooled to room temperature step by step, according to the impact-resistantglass with the coating prepared by the method, the impact resistance can be improved by 85% or more, and the coating is high in hardness, free of yellowing, strong in adhesiveness and scrub resistance, not easy to fall off, and good in weather resistance and durability.

Description

technical field [0001] The invention relates to the technical field of impact-resistant glass, in particular to a preparation method of coated impact-resistant glass. 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 scr...

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 a glass anti-impact ink and its application method, the anti-impact ink includes the following raw materials: photoinitiator, silicone modified acrylic acid Ester, vinyl coupling agent, epoxy coupling agent, silanol 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-resistant ink is limited, the hardness is soft, the coating is easily scratched, and it is easy to yellow, which is not conducive to the industrialization of the product; in addition, after the existing coating is sprayed on the glass substrate, the coating and the glass substrate The adhesion between the materials is poor, which can easily cause the coating to bubble, deform or even fall off, and the weather resistance and durability are poor
