Abstract

The invention discloses a conductive carbon black modified PP material and a preparation method thereof. The conductive PP material is prepared from components of, by weight: 55 to 75 parts of PP resin, 15 to 25 parts of conductive carbon black, 6 to 10 parts of a toughening agent, 4 to 8 parts of a compatibilizer, 0.2 to 0.4 parts of an antioxidant, and 0.1 to 0.3 parts of an acid absorbent. According to the invention, carbon black is added into PP resin, and the materials are processed through blending modification, such that a permanently conductive plastic material with adjustable resistivity is obtained. The material has permanently stable conductivity. The resistivity of the material can be adjusted within a relatively large range. The plastic material has good performance as thermoplastics, and has low price. The material is an ideal antistatic material which can be widely applied in antistatic reusable containers, pallets, wafer carriers, and film sacs in processing procedures of precise electronic components of integrated circuits, wafers, and sensor sheaths. The material can also be used in industries of electronic product EMI shielding housings in fields of telecommunications, computers, automation systems, industrial electronic products, consumption electronic products, and automobile electronic products.

Description
