Abstract

The invention relates to a novel flame-retardant foaming material, particularly, the novel flame-retardant foaming material contains the following components in parts by weight: 20-50 parts of polyvinyl chloride, 10-30 parts of polymethyl methacrylate, 5-10 parts of calcium phosphate, 5-10 parts of melamine, 5-10 parts of zinc oxide, 1-5 parts of zinc stearate, 0.5-2 parts of azodicarbonamide and 0.5-2 parts of benzoyl peroxide. By adopting the combination of calcium phosphate, melamine and zinc oxide combination as a flame retardant of the foaming material, the novel flame-retardant foaming material has excellent flame-retardant performance to achieve the B1 level (flame retardancy) requirement specified in building interior decoration design fireproof standard GB50222-95 (revised in 2001).

Description

technical field [0001] The invention belongs to the technical field of building materials and relates to a novel flame-retardant foaming material. Background technique [0002] Due to the advantages of high strength, light weight, good thermal insulation performance, and strong energy absorption capacity, foaming materials can be used as packaging materials for valuables, precision instruments, and fresh food. In addition, due to its excellent characteristics such as low thermal conductivity, low water absorption, good electrical insulation, sound insulation, moisture resistance, and simple molding process, it is widely used in roadbed laying of roads and bridges, housing construction, and insulation materials for fishing and refrigeration industries. etc. [0003] Flame-retardant foaming materials are widely used in various occasions that require fire protection because of their light weight and flame-retardant properties. However, the flame-retardant properties of existin...
