ABSTRACT:
A method to produce an anti-swelling mica having following steps:mixing powdery mica with an alkaline compound to form a mixture;heating the mixture at a temperature between 150° C.˜230° C. for lasting 30 minutes to make metal ions out of the alkaline compound to diffuse into the mica homogeneously;using water to reduce temperature of the mixture so as to form an alkaline solution;separating the powdery mica from the alkaline solution to obtain a solid mica;neutralizing excessive alkaline compound adhering to the solid mica by an acid solution that is diluted by cold water and the mica anti-swells after adjusting pH of the solid mica to less than 7.0; anddiluting the acid solution again by adding water and separating the solid mica from diluted acid solution to obtain a production—anti-swelling mica.
