Foaming type mica composite material and processing method thereof

The processing method comprises the following steps: S1, selecting mica with the fineness of 600-2200 meshes, and carrying out acid treatment and high-voltage electrostatic treatment for later use; s2, heating the high-speed mixer to 85 DEG C, adding mica powder, mixing for 5-10 minutes, drying, then adding an auxiliary agent, mixing at a high speed for 4-7 minutes, and carrying out surface treatment on the mica powder; s3, carrying out heat preservation on the high-speed mixer to 80 DEG C, adding an auxiliary material adhesive and an auxiliary agent, carrying out high-speed mixing for 3-6 minutes, and further carrying out surface treatment, modification treatment and blending; S4, adding a foaming agent in the auxiliary agent into the high-speed mixer, carrying out high-speed mixing for 3-5 minutes, then taking out the materials, pouring the materials into a low-speed stirrer, and carrying out low-temperature cooling stirring for 4-10 minutes, so as to obtain a finished product.
