Abstract

The invention discloses a halogen-free phosphorus-nitrogen composite flame retardant. The composite flame retardant is prepared from the following components in parts by weight: 40-89.5 parts of aluminum diethylphosphinate, 5-45 parts of organic aluminum phosphite, 5-45 parts of phosphonitrile and 0.5-10 parts of a heat stabilizer, wherein the organic aluminum phosphite is methyl or ethyl substituted aluminum phosphite, and the heat stabilizer is a zinc salt compound and/or cerium oxide. The invention aims to provide the halogen-free phosphorus-nitrogen composite flame retardant with high glowing filament performance and high flame retardancy. The flame retardant can be applied to non-filled or filled thermoplastic polymers, especially has excellent flame retardancy to glass fiber reinforced engineering plastic, and can be used to prepare parts or products in the field of electronic equipment.

Description

technical field [0001] The invention relates to the technical field of halogen-free flame retardants, in particular to halogen-free phosphorus-nitrogen composite flame retardants and halogen-free flame-retardant thermoplastic polymers containing the same. Background technique [0002] Many plastics are highly flammable due to their chemical composition, so in order to improve the fire resistance of plastics, it is necessary to add certain flame retardants to meet the requirements. When a fire occurs, halogen-containing flame-retardant materials will produce a large amount of smoke and toxic corrosive hydrogen halide gas during the flame-retardant process, causing secondary hazards. Therefore, with the improvement of environmental awareness, halogen-free flame retardant products are becoming more and more popular among researchers and consumers. [0003] At present, the known halogen-free flame retardants are mainly phosphorus-nitrogen flame retardants and metal hydroxides. ...
