Abstract

An antistatic polyester alloy material and a preparation method thereof, the polyester alloy material comprises the following components according to the weight ratio: 30-50 parts of polybutylene terephthalate, 50-70 parts of polycarbonate 2.1 to 11 parts of conductive particles, 3 to 15 parts of toughening agent, 0.1 to 1 part of antioxidant and 0.2 to 1 part of lubricant. The conductive particles are composed of 2 to 10 parts of conductive carbon black and 0.1 to 1 part of Granular conductive particles formed by banburying silicone oil, the antistatic polyester alloy material prepared by the present invention has a uniform and stable surface resistance, and can overcome the problems of delamination and bridging during the blanking process of conductive carbon black , greatly reducing the amount of conductive carbon black added.

Description

Technical field[0001]The invention relates to the technical field of polymer material processing, in particular to an antistatic polyester alloy material and a preparation method thereof.Background technique[0002]At present, in home appliances and industrial application scenarios, it is easy to absorb dust when the fan blades, electrical appliances and other equipment are placed and operated. The accumulation of dust for a long time will cause the appearance of dust, which affects the appearance, is difficult to clean, and can also cause poor operation , The problem of attenuation of the damaged life of electrical appliances, so in order to be able to effectively prevent dust, the surface resistance of the material needs to be as high as 10^8-9.[0003]As a high-quality conductive filler, conductive carbon black can change the surface resistance of the substrate. However, because the bulk density of conductive carbon black is quite different from that of powder and granular materials,...
