AI Technical Summary

Problems solved by technology

However, these two types of modification methods have their own shortcomings: the conductive fillers are easy to agglomerate, difficult to disperse, the content of fillers required to form a conductive network is relatively high, the cost increases, and the color is single, which greatly limits the application field of PC. Due to migration, electrostatic agents or conductive polymers will migrate and lose to the outer surface of the material with time, and the antistatic durability is poor
In addition, due to the high processing temperature of PC, many types of antistatic a

Abstract

The invention discloses a halogen-free flame-retardant antistatic PC material and a preparation method thereof. The halogen-free flame-retardant antistatic PC material is prepared from the following raw materials in percentage by mass: 70%-90% of PC pure resin, 1%-5% of an antistatic agent, 1%-5% of a flexibilizer, 0.2%-0.5% of an antioxidant, 0.2%-0.5% of a lubricant, 5%-10% of a flame retardant and 0.1%-0.5% of an anti-dripping agent. The invention also discloses a preparation method of the halogen-free flame-retardant antistatic PC material. The halogen-free flame-retardant anti-static PC material prepared by the invention has excellent anti-static performance, high flame-retardant effect, excellent mechanical property and easiness in forming and processing, and the prepared PC composite material can be used for electronic devices and products of precise instrument packaging shells.

Description

technical field [0001] The invention relates to the technical field of polycarbonate materials, in particular to a halogen-free flame-retardant and antistatic PC material and a preparation method thereof. Background technique [0002] PC is polycarbonate, which is an engineering plastic with good comprehensive performance. It has high strength, high elastic modulus, high impact strength, high transparency, low molding shrinkage, good dimensional stability, good fatigue resistance and weather resistance. It is widely used in glass assembly industry, automobile industry, electronics and electrical industry, as well as industrial machinery parts, CDs, packaging, computers and other office equipment, medical and health care, film, leisure and protective equipment and other fields. However, the antistatic performance of PC is poor. If the antistatic performance of PC can be improved, the application of PC resin in automobiles, aviation, office machines, electronics and other fiel...
