Abstract

The invention discloses a high-efficiency flame-retardant material, and belongs to the technical field of flame-retardant materials. According to the invention, raw materials like glass fiber and basalt fiber are subjected to grinding and activation treatment, and treated raw materials are mixed and homogenized with rice washing water and swim bladders, so macromolecular proteins are dissolved out; polyvinylpyrrolidone is added to provide the action of cross-linking homopolymerization, so a macromolecular polymerization network is constituted; meanwhile, a hard component namely graphene oxideis added for filling the macromolecular polymerization network to prepare a toughening reinforcer, so mechanical strength and heat-dissipating and flame-retardant effects in a composite flame-retardant base material are assisted to be improved. With boron nitride and carbon nanotubes and the like as raw materials, a high-efficiency heat-conducting network is constituted in cooperation; through linear lap joint of the carbon nanotubes, a heat flow path is directly formed; a heat flow network is constituted by point-contact heat flow paths constituted by connection of silicon nitride; a dense heat conduction-heat insulation ordered integrity is formed; and by combination of a variety of organic and inorganic components, the effects of toughening and strengthening are provided, and mechanicalstrength is improved. The high-efficiency flame-retardant material provided by the invention solves the problems of low flame-retardant efficiency and poor mechanical strength of a conventional commonly-used flame-retardant material.

Description

technical field [0001] The invention belongs to the technical field of flame retardant materials, and in particular relates to a high-efficiency flame retardant material. Background technique [0002] Flame retardant materials mainly include organic and inorganic, halogen and non-halogen. Inorganic flame retardant materials are the most widely used flame retardant materials at present. Its main components are inorganic substances. Among them, the aluminum-magnesium series is non-toxic, halogen-free, smokeless, low in price, and easy to store. The filling amount is very large, which has a great influence on the physical properties and mechanical properties of the substrate. Inorganic phosphorus is halogen-free, low toxicity, stable and long-lasting, but red phosphorus is easy to absorb moisture and oxidize, and will generate highly toxic PH 3 gas. Inorganic antimony-based flame-retardant materials are mainly antimony trioxide, which produces a large amount of smoke during ...
