Abstract

The invention discloses a novel nanometer flame-retardant composite material. The composite material is characterized by comprises the following substances by weight: 35 to 70 parts of glass fiber reinforced polyethylene terephthalate ester, 15 to 23 parts of rare earth phenyl phosphonate, 10 to 20 parts of aluminum hydroxide, 3 to 8 parts of ethylene acrylate, 1 to 9 parts of high density polyethylene, 5 to 9 parts of diammonium phosphate, 3 to 11 parts of hexabromo water dispersion, 4 to 12 parts of superoxide dismutase, 10 to 18 parts of tetra(3,5-di-tert-butyl-4-hydroxy)pentaerythritol phenylpropionate, 20 to 31 parts of methyl benzoate, 5 to 17 parts of polyvinyl alcohol and 10 to 24 parts of chlorobenzene. The novel nanometer flame-retardant composite material has a wide application scope, reduces the usage amount of a fire retardant, enables cost to be saved, accords with the trend of environmental protection and conservation, is simple and easy to prepare and process, exerts an obvious effect, accords with practical application conditions and is quite possible to be marketed.

Description

technical field [0001] The invention relates to a novel nano flame-retardant composite material. Background technique [0002] Polyethylene terephthalate (PET) is one of the most widely used synthetic fiber materials and is widely used as fiber and film materials. In recent years, PET has attracted more and more attention as engineering plastics, especially glass fiber Reinforced PET engineering plastics (Glass-fiber reinforced Poly (ethylene terephthalate), abbreviated as GF-PET) are not only low in price, but also have excellent dimensional stability, high strength and high modulus, making them widely used in automobiles, home appliances, There are more and more applications in electrical, mechanical and other fields. However, one of the shortcomings of GF-PET that cannot be ignored is its flammability. The low oxygen index value of 18-20% and the large amount of smoke produced during combustion can easily cause fire and cause the fire to spread rapidly. Extensive applic...
