Abstract

The invention discloses a high-CTI, high-heat-resistance, halogen-free and flame-retardant PC / ABS composition and a preparation method thereof. The composition comprises the following raw materials in parts by weight: 65-90 parts of polycarbonate, 3-10 parts of ABS resin, 4-10 parts of self-made phosphosilicate polymer, 3-10 parts of modified porous material, 1-5 parts of thickening agent, 0.1-0.3 part of antioxygen, 0.3-0.7 part of anti-dripping agent, and 0.2-0.5 part of lubricating agent. According to the high-CTI, high-heat-resistance, halogen-free and flame-retardant PC / ABS composition,the defects of low CTI, high dosage of phosphorus based flame retardant, low flame retarding performance and low thermal deformation temperature of a traditional halogen-free flame-retardant PC / ABSresin are solved; the complex system of the self-made phosphosilicate polymer and the porous material is selected, and a continuous net shaped carbon layer structure is formed through an electric field and electrolyte, so that the resin is high in CTI, and high in thermal deformation temperature; the thermal deformation temperature of the prepared PC / ABS composition is up to 113 DEG C, and the CTI is up to 450V.

Description

technical field [0001] The invention belongs to the technical field of alloy materials, and relates to a halogen-free flame-retardant modified resin composition, more specifically, to a high-CTI, high-heat-resistant halogen-free flame-retardant PC / ABS composition and a preparation method thereof. Background technique [0002] At present, PC / ABS alloy is widely used in electronic appliances, automobile industry, office equipment, communication equipment, household appliances and other fields. However, with people's emphasis on safety, electronic and electrical products have higher and higher requirements on the heat resistance and CTI value of materials. Tracking is the ability of the surface of a material to form a conductive path under the action of an electric field and an electrolyte, and the CTI value is an important indicator to measure the tracking resistance of a material. Since traditional halogen-free flame-retardant PC / ABS mostly uses phosphate ester as a flame re...
