Problems solved by technology

However, the problems of environmental protection and safety of some halogenated flame retardant materials are becoming more and more obvious
For example, tests have found that polybrominated diphenyl ether (PBDPO) and its flame-retardant materials will generate toxic carcinogens polybrominated dibenzodioxin (PBDD) and polybrominated dibenzofuran ( PBDF), and some brominated flame retardant materials flame retardant high polymer will generate a lot of smoke and corrosive gas during thermal cracking and burning, which is harmful to the environment and biology

Embodiment 1

[0010] A flame-retardant composite material, the raw materials according to weight percentage include: polyethylene terephthalate 30%, polyhedral silsesquioxane 5%, butadiene styrene brominated copolymer 20%, polyethylene terephthalate 9% benzobisoxazole, 5% melamine fiber, 8% phenolic fiber, 7% acrylic fiber, 8% pre-oxidized yarn, 8% silicon carbide fiber.

[0011] Polyhedral silsesquioxane (POSS) is a kind of characteristic organosilicon flame retardant, which can show excellent flame retardancy, mechanical and thermal properties at extremely low addition amount; butadiene styrene brominated copolymer Although it contains brominated halogens, it is an environmentally friendly polymer flame retardant with a large molecular weight. This large molecular weight is not easy to bioaccumulate, which is beneficial to health and environmental protection. In composite materials, it will not migrate and precipitate, will not hydrolyze and degrade, and has good aging and water resistanc...

Embodiment 2

[0012] Embodiment 2: A kind of flame-retardant composite material, the raw material according to weight percentage comprises: polyethylene terephthalate 35%, polyhedral silsesquioxane 2%, butadiene styrene brominated copolymer 23% , 6% poly-p-phenylene benzobisoxazole, 4% melamine fiber, 8% phenolic fiber, 9% acrylic chloride fiber, 6% pre-oxidized silk, 7% silicon carbide fiber.

[0013] In this embodiment, the content of polyhedral silsesquioxane is reduced to 2%, and other materials adopt the aforementioned ratio, and the obtained flame-retardant composite material is still excellent in flame retardancy, mechanical and thermal properties, and it is used for the casing of electronic products, and the service life is long. Long-lasting and will not deteriorate.

Embodiment 3

[0014] Embodiment 3: A kind of flame-retardant composite material, the raw material according to weight percentage comprises: polyethylene terephthalate 30%, polyhedral silsesquioxane 4%, butadiene styrene brominated copolymer 30% , 6% poly-p-phenylene benzobisoxazole, 6% melamine fiber, 6% phenolic fiber, 6% acrylic chloride fiber, 6% pre-oxidized silk, 6% silicon carbide fiber.

[0015] The flame-retardant composite material obtained in this embodiment has good flame-retardant ability, environmental protection, good aging resistance and water resistance, and has good mechanical and thermal properties. It is used in the casing of electronic products, and it can be used for a long time without deterioration.

Abstract

The invention relates to a flame-retarding composite material including, by weight, 25-35% of polyethylene glycol terephthalate, 2-18% of polyhedral silsesquioxane, 10-30% of a butadiene-styrene bromide copolymer, 5-13% of poly-p-phenylenebenzobisoxazole, 3-8% of melamine fibers, 6-10% of phenolic fibers, 5-10% of Vinyon N fibers, 5-10% of pre-oxidized fibers, and 6-10% of silicon carbide fibers. The composite material has flame-retarding effects and is environment-friendly, is anti-aging, has excellent waterproofing property, and has excellent mechanical and thermal performances.

Description

technical field [0001] The invention relates to the field of flame retardant materials, in particular to a flame retardant composite material. Background technique [0002] Composite materials are widely used in housings or components of electronic products, and their advantages are that they are easy to shape and can be mass-produced. In order to improve the high temperature resistance and fire resistance of composite materials, flame retardant components are usually added to composite materials. How to add appropriate flame retardant ingredients to composite materials to improve the fire resistance of composite materials has become one of the main research and development topics at present. [0003] At present, bromine-based flame-retardant materials are still one of the most important flame-retardant material products. There are more than 70 varieties of bromine-based flame-retardant materials. Small size, wide range of applications, moderate price and so on. However, ...
