Abstract

The invention discloses a method for preparing an organic silicon resin material. The method comprises the following steps: mixing first alkyl chlorosilane and xylene to generate hydrolysis reaction, heating the mixture obtained after hydrolysis reaction to generate condensation polymerization, thereby preparing an organic silicon prepolymer; reacting second alkyl chlorosilane with epoxy resin, thereby preparing a modified resin prepolymer; performing polymerization reaction on the organic silicon prepolymer and the modified resin prepolymer, thereby preparing an organic silicon half-finished resin product; and uniformly mixing the organic silicon half-finished resin product, a curing accelerant and an adhesion accelerant, thereby preparing the organic silicon resin material. According to the scheme, as the organic silicon half-finished resin product is prepared by taking first alkyl chlorosilane, second alkyl chlorosilane and xylene as reaction raw materials, and the organic silicon half-finished resin product is mixed with the curing accelerant and the adhesion accelerant to prepare the organic silicon resin material, the organic silicon resin material is resistant to high temperature of 620 DEG C, the cold hardness is up to 7H, the acid / alkali resistance is achieved, the curing temperature is 40-50 DEG C, and the adhesion property is remarkably improved.

Description

[0001] technical field [0002] The invention relates to the field of resin material production, in particular to a method for preparing an organic silicon resin material. Background technique [0003] Silicone resin, also known as polysiloxane, is a general term for a class of polymers that are composed of silicon atoms and oxygen atoms alternately connected, and different organic groups are connected with silicon atoms. The structure of silicone resin contains both "organic group" and "inorganic structure". This special composition and molecular structure make it integrate the characteristics of organic matter and the function of inorganic matter. One of the most prominent properties of silicone resin is its excellent thermo-oxidative stability. After heating at 250°C for 24 hours, the weight loss of silicone is only 2% to 8%. After heating at 350°C for 24 hours, the silicone resin The weight loss is also less than 20%, and its performance is far superior to polycarbonate...
