Abstract

Provided is a glass shatter-proof glue composition, comprising: (A) an organopolysiloxane having a straight chain structure and having at least two alkenyl groups bonded with silicon per molecule; (B) a polyorganohydrogensiloxane having a straight chain structure and having at least two hydrogen atoms bonded with silicon per molecule; (C) an organopolysiloxane having a solid three-dimensional structure and comprising a R 1 3SiO 1 / 2 unit and an SiO 4 / 2 unit; (D) a fumed silica with a mesh number of 200-4000 mesh; and (E) a hydrosilylation catalyst in an amount sufficient to accelerate the curing of the composition. Also provided are a glass product and the application method of the glass shatter-proof glue combination on the glass product. The production process of the composition is simple, only requiring low-temperature baking, and has a high production efficiency.

Description

technical field [0001] The invention relates to a silicone composition, in particular to a glass anti-shatter adhesive composition and its application, and glass products coated with the composition. Background technique [0002] With the development of clean energy, especially the development of LED lamps and photovoltaic industries, the performance requirements for related glass products are also getting higher and higher. In addition to the requirements of aesthetics and high light transmittance, there are also high requirements for the impact strength of glass products. [0003] Improving the impact strength of glass products usually has the following methods. One is to improve the strength of the glass product itself by improving the glass formula or process; the other is to attach a layer of explosion-proof strengthening film to the glass product, such as the explosion-proof film of automobile glass; The third is to apply a layer of paint to the surface of the glass p...
