Abstract

The invention discloses a polypropylene conductive plastic and a preparation method thereof. The polypropylene conductive plastic comprises the following components in parts by weight: 40-50 parts of PP, 30-40 parts of carbon black, 20-25 parts of PP-g-MAH, 8-10 parts of ethylene-propylene rubber, 10-15 parts of powdered aluminum, 1-15 parts of titanium tetrabutoxide, 5-9 parts of dioctyl terephthalate, 5-6 parts of sodium sulfite, 10-19 parts of ammonium persulfate, 12-18 parts of diisobutyl phthalate, and 11-17 parts of isoeugenol. The polypropylene conductive plastic of the present invention has very good mechanical properties, high impact strength and relatively low shrinkage, good stability and no proneness of deformation; and also has good conductivity, so the plastic can be widely used in anti-electromagnetic interference products, etc., and can be used to replace metal materials, wherein superior performance and lower cost can be achieved.

Description

technical field [0001] The invention relates to the field of plastics, in particular to a polypropylene conductive plastic and a preparation method thereof. Background technique [0002] As an insulator, plastic is widely used in various fields, modern life plastic products due to Non-conductive The material will have higher corrosion resistance, so that the plastic can obtain a metal effect surface with a higher yield and lower cost, and improve wear resistance. However, compared with metal plating, plastic products Non-conductive , It is not easy to carry out electroplating treatment, so surface metallization treatment is required before electroplating, so that plastic have conductive sex. With the development of the modern electronics industry, the defects of electronics are becoming more and more obvious. It is necessary to solve the problem of electromagnetic shielding, but it is difficult for ordinary electronic products to do this. The invention provides a con...
