Preparation method of high temperature resistant high-strength abrasive belt

The invention relates to a preparation method of a high temperature resistant high-strength abrasive belt and belongs to the technical field of abrasive tool material preparation. The preparation method comprises the steps that firstly, rice hulls are soaked in a citric acid solution and alkali liquor in sequence, then the rice hulls and kaolinite are mixed and ground, tetraethoxysilane is added for mixing, and a mixture is obtained; secondly, corn starch is added into the mixture for enzymolysis, and zymolytes are prepared; and thirdly, the zymolytes, phenolic resin and other mixing materialsare mixed and coated on a composite intersecting layer for hot pressing, and the high temperature resistant high-strength abrasive belt is prepared after cooling and solidification are performed. According to the preparation method of the high temperature resistant high-strength abrasive belt, plant fiber in the rice hulls is separated first, meanwhile, carboxyl groups adhere to the surface of the plant fiber, the adsorp
