Environment-friendly type building insulation sheet material and preparation method thereof

Abstract

The invention discloses an environment-friendly type building insulation sheet material and a preparation method thereof. The preparation method of the building insulation sheet material comprises the following steps: 1) taking perlite, polymerization alumina, calcium boride and magnesium nitride, respectively performing ball milling on the above components in a ball mill; 2) respectively weighing the following components in parts by weight: 8-15 parts of o-cresol formaldehyde epoxy resin, 4-10 parts of polyvinylidene fluoride, 6-12 parts of rigid polyurethane foam, 3-6 parts of perlite, 4-9 parts of polymerization alumina, 4-8 parts of calcium boride, 2-6 parts of magnesium nitride and 5-10 parts of polymethacrylimide, mixing the above components to an uniform state; and 3) compacting the uniformly mixed insulation material and moulding to obtain the environment-friendly type building insulation sheet material. The environment-friendly type building insulation sheet material has the characteristics of high compressive strength, high breaking strength and good thermal insulation performance.
