Abstract

The invention relates to a halogen-free inflaming-retarding conductive PC resin composition, and a preparation method thereof. The composition is prepared from raw materials of, by weight: 40 to 95% of PC resin, 1 to 10% of an impact modifier, 2 to 15% pf a halogen-free inflaming retardant, 1 to 10% of an inflaming retardant synergist, 0.1 to 1.5% of an anti-dripping agent, 1 to 15% of a conductive material, 0.1 to 2% of a lubricant, and 0.1 to 1% of an anti-oxidant. PC resin is dried in an air dry oven at a temperature of 120 DEG C for 2 to 4 hours; raw materials weighed according to the weight ratio are mixed in a low-speed mixer for 3 to 5 minutes; the mixed raw material is added to a hopper of a twin screw extruder, and is fused, extruded, and granulated. According to the invention, excellent physical properties of PC resin are maintained, and the composite has good inflaming-retarding performance and conductivity. The halogen-free inflaming-retarding conductive PC resin composition can be widely applied in industries of automobiles, astronautics and aerospace, and electronics and electrics.

Description

technical field [0001] The invention relates to a resin composition, in particular to a halogen-free flame-retardant conductive PC resin composition and a preparation method thereof, which can be widely used in automobile, aerospace and electronic and electric industries. Background technique [0002] In recent years, with the deepening of the concept of social sustainable development, people's awareness of environmental protection and safety has been greatly improved, and their awareness of ecological environment and safety has been greatly improved. Attention is also more important. Reducing and preventing the adverse effects of traditional halogen flame retardants on the environment and human health has become an urgent issue in the current flame retardant polymer material industry. Halogen-free flame-retardant polymer materials are favored by the society because of their low toxicity and environmental protection. It has broad application prospects because of its unique ...
