Problems solved by technology

Although the flame retardant effect of the traditional halogen-based flame-retardant system is good, it generates more smoke, corrosive gas and toxic gas during combustion. Therefore, the use of the traditional halogen-based flame-retardant system has potential harm to the environment and human body, and is not environmentally friendly. With the development of society, people's requirements for environmental protection and safety are increasing day by day, and the promulgation of the European Union's "RoHS Directive", the development of high-efficiency, lead-free, mercury-free, cadmium, hexavalent chromium, polybrominated biphenyls and polybrominated diphenyl ethers and other harmful substances, smoke generation Small, non-toxic and environmentally friendly flame-retardant ABS resin is of great significance and has a huge market space

Abstract

The invention provides halogen-free environmentally-friendly flame-retardant ABS / PC resin alloy, which is characterized by comprising the following materials by mass: 40-70 parts of ABS resin, 20-30 parts of PC resin, 5-10 parts of modified montmorillonite, 10-15 parts of a composite flame retardant, 0-5 parts of a synergistic effect flame retardant, 1-3 parts of an antioxidant, 3-6 parts of a lubricant and 0-5 parts of an inorganic filler. The halogen-free environmentally-friendly flame-retardant ABS / PC resin alloy keeps properties of the ABS resin and the PC resin, and the resin alloy has excellent mechanical and flame retardant properties.

Description

technical field [0001] The invention relates to the technical field of flame-retardant polymer materials, in particular to a halogen-free, environment-friendly, flame-retardant ABS / PC resin alloy. Background technique [0002] Acrylonitrile-butadiene-styrene plastic (ABS) combines the rigidity and heat resistance of acrylonitrile, the gloss and processability of polystyrene, and the impact resistance of polybutadiene, and can be widely used in Household appliances, office equipment, instrumentation, transportation, building materials, daily necessities and packaging materials and other fields. However, the limiting oxygen index (LOI) of ABS is only 18%, which is a flammable material. In order to improve its combustion behavior and make it difficult to burn or self-extinguish when it is away from fire, it is necessary to modify the flame retardant of ABS. [0003] At present, traditional halogenated flame retardants are mainly used in the flame retardant system of ABS, amon...
