Problems solved by technology

Halogenated flame retardants have a good cost-effectiveness balance and are widely applicable. However, due to the large amount of smoke generated, the released gas is highly corrosive, and brominated flame retardants decompose into polybrominated dibenzos under certain conditions. Dioxane (PBDD) and polybrominated dibenzofuran (PBDF) substances, which have strong carcinogenic effects

Abstract

The present invention relates to one kind of no-halogen fire retardant thermoplastic engineering plastic, which is prepared with nylon-66 200-700 weight portions, glass fiber 100-500 weight portions, fire retarding system comprising phosphate-containing fire retardant 50-300 weight portions and mineral fire retardant 10-300 weight portions, and antioxidant with hindered phenol as main component 1-10 weight portions. Compared with available technology, the present invention has the advantages of high CTI, low smoking amount, low toxicity, environment friendship, etc.

Description

technical field [0001] The invention relates to a flame-retardant thermoplastic composition, in particular to a halogen-free flame-retardant thermoplastic engineering plastic. Background technique [0002] Thermoplastic materials used in materials such as household appliances switches and electric tool casings have certain requirements for heat resistance and fire prevention. Nylon 66 resin itself is a flammable polymer material, which will release a large amount of smoke and harmful gases when burned, so that it will cause "secondary disasters" during the burning process. For example: Nylon 66 is 1 / 8″UL-V2 grade, and its limiting oxygen index is 28.3. This limits the application of nylon 66 in electronic appliances. [0003] At present, the most commonly used method to improve the flame retardancy of nylon 66 is to add halogen-containing flame retardants. Halogenated flame retardants have a good cost-effectiveness balance and are widely applicable. However, due to the lar...
