Problems solved by technology

[0002] As an engineering plastic, polycarbonate (PC) has high impact strength, good creep resistance, good electrical insulation and dimensional stability; however, due to the high melt viscosity of PC, fluidity, solvent resistance and Wear resistance is poor, its application is limited
Polybutylene terephthalate (PBT) is a crystalline thermoplastic with fast crystallization speed and is suitable for high-speed molding. It has the advantages of chemical resistance and melt fluidity, but the notched impact strength is low.
The blending and modification of PC and PBT can complement each other, but the flame retardancy of the two blends is not good. Although the flame retardancy of PC itself can reach UL94 V-2 level, the addition of PBT reduces the flame retardancy of PC. sex

Abstract

The invention discloses a flame retardation antistatic polycarbonate / polybutylene telephthalate composition. The composition comprises the following ingredients, by weight, 40%-60% of PC, 20%-30% of PBT, 6%-12% of halogen free flame retardants, 2%-5% compatilizers, 1%-3% of antistatic agents, 0.1%-1% of triphenyl phosphate, 0.1%-0.5% of anti-oxidants and 0.1%-1% of lubricants. The halogen free flame retardants are a mixture of phosphorus-based flame retardant polysulfonyldiphenylene phenyl phosphonate and silicon-based flame retardant polydimethylsiloxane with a weight ratio of 3:1. The beneficial effects are that the composition has good antistatic performance and flame retardation performance, and meets halogen free, low smoke and UL94V-0 level flame retardation requirements.

Description

Technical field [0001] The invention relates to the technical field of polymer materials, in particular to a flame-retardant antistatic polycarbonate / polybutylene terephthalate composition. Background technique [0002] Polycarbonate (PC), as an engineering plastic, has high impact strength, good creep resistance, good electrical insulation and dimensional stability; but because of the high melt viscosity of PC, fluidity, solvent resistance and The wear resistance is poor, and its application is limited. Polybutylene terephthalate (PBT) is a crystalline thermoplastic with fast crystallization speed and suitable for high-speed molding. It has the advantages of chemical resistance and good melt fluidity, but has low notched impact strength. . The blending modification of PC and PBT can have complementary advantages, but the flame retardancy of the blending of the two is not good. Although the flame retardancy of PC itself can reach UL94 V-2, the addition of PBT reduces the flame ...
