Abstract

The invention relates to an oil-resistant electric-leakage-resistant halogen-free flame-retardant PC insulating material composition and a preparation method. The oil-resistant electric-leakage-resistant halogen-free flame-retardant PC insulating material composition comprises polycarbonate, a compatilizer, polyester, an antioxidant, a halogen-free flame retardant, a phosphorus flame retardant and an anti-dripping agent. The oil-resistant compatibilizer and the polyester raw material are added into the polycarbonate for compounding according to the optimal proportion, and the oil-resistant compatibilizer and the polyester raw material can be uniformly distributed in the polymer, have good compatibility with the polycarbonate, and have excellent synergistic oil resistance, so that the flame retardance of a product with the thickness of 1.60 mm can reach the UL-94V-0 level, the mechanical property of the product is not influenced, the product is not cracked due to oil stains, the insulation effect is kept, the tracking resistance reaches 250V, and the safety standard of the electric melting shell of the electronic and electrical product is met.

Description

technical field [0001] The invention belongs to the field of PC insulating materials, and in particular relates to an oil-resistant, anti-leakage, halogen-free flame-retardant PC insulating material composition and a preparation method. Background technique [0002] At present, halogen-free flame-retardant PC can achieve flame-retardant 0.8mm thickness UL-94 can reach V-0 level, this material is often widely used in the field of capacitor shells of electronic appliances, and has good insulation and anti-leakage tracking ability. The tracking resistance performance is mainly due to the conductive substances deposited on the surface of insulating materials by live parts of different polarities in the actual use of electrical products, causing creepage on the surface of insulating materials, breakdown short circuit and fire hazard. During the use of electrical products, due to the leakage of lubricating oil and dirt during the long-term operation of the motor, the corrosion and...
