Fireproof polystyrene thermal-insulation layer material

Abstract

The invention relates to a fireproof polystyrene thermal-insulation layer material. The fireproof polystyrene thermal-insulation layer material comprises the following components in parts by weight: 115 parts of polystyrene, 10 parts of polyvinyl alcohol, 2 parts of antimonous oxide, 5 parts of a magnesium hydroxide flame retardant, 10 parts of polystyrene, 34 parts of kaolin, 4 parts of zinc borate, 3 parts of polypropylene cellulose, 3 parts of phthalate, 4 parts of a brominated flame retardant and 2 parts of polytetrafluoroethylene. Polystyrene foam disclosed by the invention has very scarce and excellent flame retardant effects and remarkable fireproof and heat insulation effects, can be used for effectively preventing a polystyrene thermal-insulation board from heat shrinkage at an early stage, can prevent and delay the combustion of the polystyrene thermal-insulation board. Moreover, the fireproof polystyrene thermal-insulation layer material has excellent mechanical performance, high mechanical strength and strong crack resistance, can be used for improving the interface protective capacity and reducing the damage degree of the thermal-insulation layer.

Description

technical field [0001] The invention relates to a chemical product, in particular to a fireproof polystyrene insulation layer material. Background technique [0002] In recent years, fire accidents of thermal insulation materials and external wall insulation systems have occurred frequently. Frequent fire accidents of building insulation have not only caused huge economic losses and environmental pollution. In the thermal insulation system widely used at present, polystyrene is the key to its fire safety performance. From the current technical level, it is difficult to achieve high-standard polystyrene flame retardancy indicators. Simply increasing the amount of flame retardants will not only increase the cost of process materials, but also obviously the toxicity of flame retardants will also affect human health. Life poses a great threat. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a fireproof polystyrene insulati...
