Method for improving the heat resistance of silicone resin

Method for improving the heat resistance of silicone resin, which relates to a method for improving the heat resistance of silicone resin. It solves the problems of high cost, unsuitable for large-scale industrial production and raw materials difficult to obtain. Methods: by crushing, screening, grinding method to achieve micron level the mica particle size; second, the use of plasma, high temperature, high speed dispersing, colloid mill dispersion or ultrasonic vibration method processing sericite;, concentrated hydrochloric acid or concentrated nitric acid acidification sericite; fourth, with saturated sodium carbonate or saturated sodium chloride solution by ion exchange; fifth, and silicone resin were polymerization. The raw material of the invention is easy to obtain, and the cost is low, which is suitable for industrial production and can be used to improve the heat resistance of other thermosetting resins. Compared with the heat resistance of modified silicone resin, the initial decomposition temperature of silicone resin was 154 degrees, the temperature of the two time was 609 degrees, and the heat resistance was improved obviously.
