Abstract

The invention discloses a heat-resistant halogen-free flame-retardant PC / ABS composite material and a preparation method thereof. The halogen-free flame-retardant PC / ABS composite material comprises the following components in parts by weight: 70-80 parts of PC resin, 5-10 parts of ABS resin, 12-15 parts of an organic phosphorus compound flame retardant, 3-5 parts of a toughening agent, 0.3-0.5 part of an anti-dripping agent, 0.1-0.3 part of an antioxidant. and 0.3 to 0.5 part of a lubricant. According to the technical scheme provided by the invention, the PC / ABS composite material is subjected to flame-retardant modification treatment by using the organic phosphorus compound with good fluidity and high melting point, so that the fluidity of the composite material can be effectively improved, and meanwhile, a good thermal deformation temperature is kept. Compared with an existing halogen-free flame-retardant PC / ABS alloy system, the halogen-free flame-retardant PC / ABS alloy system has the advantages of simple production process, no need of special preparation or treatment, high cost performance and favorable application prospect, and is particularly suitable for large household appliances such as display rear shells.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a heat-resistant halogen-free flame-retardant PC / ABS composite material and a preparation method thereof. Background technique [0002] Halogen-free flame-retardant PC / ABS alloy combines the excellent properties of PC and ABS, reduces the cost of PC and melt viscosity, improves processing performance, reduces internal stress of products, and improves the heat resistance, impact strength and tensile properties of ABS Strength, with excellent electrical insulation, elongation, dimensional stability, high impact strength and cold resistance, also has the advantages of flame retardancy, environmental protection, non-toxic and colorable, widely used in home appliances, automobiles, consumer electronics, electric tools, rail transit and other industries. [0003] Halogen-free flame-retardant PC\ABS alloys currently mainly use phosphate ester flame retardants such as TPP, BDP...
