Abstract

The invention discloses a method for preparing a protective film for glass and belongs to the technical field of high-polymer materials. The method comprises the following steps: (1) preparing modified silicone resin; (2) preparing nano filler; and (3) uniformly mixing the modified silicone resin, the nano filler, an ethylene-vinyl acetate copolymer, propylene oxide, boron fibers, a silane coupling agent, poly(butyl acrylate) and deionized water, spraying the mixture to the surface of the glass by the thickness of 0.05mm to 0.2mm, and carrying out curing, thereby preparing the protective film for the glass. According to the method for preparing the protective film for the glass, disclosed by the invention, the protective film for the glass is obtained by means of modifying the silicone resin and meanwhile carrying out modifying by using the nano filler; and by using the relatively excellent strength and toughness of the protective film for the glass, the impact resistance of a glass material can be effectively improved, and the injury to human bodies caused by glass breaking is avoided, so that the protective film is an ideal protective film which is relatively low in cost and relatively convenient in use.

Description

technical field [0001] The invention discloses a method for preparing a glass protective film, which belongs to the technical field of high polymer materials. Background technique [0002] Glass, since its invention, has always been a necessity in people's lives. In the fields of home, work and automobiles, glass has an irreplaceable status as an ideal light-transmitting and windshielding material. Moreover, glass materials have a relatively simple preparation process and low cost. Features, therefore, are particularly widely used. [0003] However, when glass materials are full of people's lives, glass materials are highly brittle and fragile, which makes glass materials inconvenient for transportation and processing. Moreover, when glass materials are broken, it is very easy to cause damage to people's personal safety. The slag is even more inconvenient to clean up, causing secondary damage. Therefore, safety glass and explosion-proof glass are on the rise. [0004] Ex...
