Abstract

The invention discloses a fireproof flame-retardant material. The fireproof flame-retardant material is prepared from the following raw materials: in parts by mass, 40-50 parts of polybutylene terephthalate, 110-130 parts of epoxy resin, 30-40 of hydroxyethyl cellulose, 12-20 parts of asbestos powder, 30-40 parts of calcium carbonate, 6-8 parts of perlite, 5-10 parts of dimethylacetamide, 4-6 parts of ethyl acetate, 6-8 parts of magnesium hydroxide, 25-35 parts of acrylic acid emulsion and 20-30 parts of stearyl methacrylate. The fireproof flame-retardant material has good heat insulation andfire resistance, no cracking, no falling off and high temperature resistance, and is economical and environmentally friendly.

Description
