Method for preparation of machinable mica glass ceramic insulating material from waste glass and phlogopite

The invention relates to a method for preparation of machinable mica glass ceramic insulating material from waste glass and phlogopite. The method specifically includes the steps of: washing the waste glass and phlogopite repeatedly, and conducting breaking, crushing and sieving for standby use; mixing the above two powder according to a mass ratio (with the mica accounting for 50-75%), performing grinding, adding 4-5wt% of polyvinyl alcohol as a binder, carry out dry pressing and cold isostatic pressing molding, placing the molded sample into a muffle furnace to perform pressureless sintering at 800DEG C-1500DEG C, carrying out heat preservation for 2h, performing natural cooling to room temperature, and then taking the sample out, thus obtaining the machinable mica glass ceramic insulating material prepared from waste glass and phlogopite. The material has the advantages of low cost, high strength and good electrical insulation properties, etc.
