Antistatic injection molding material for preparing electronic parts

Abstract

The invention discloses an antistatic injection molding material for preparing electronic parts. The antistatic injection molding material is prepared from, by weight, 12-18% of glyceryl stearate, 16-20% of polycarbonate, 5-9% of a plasticizer, 5-9% of a lubricant, 4-10% of an antistatic agent and the balance acrylonitrile-butadiene-styrene copolymer. The antistatic agent is formed by mixing, by mass, 8-12% of lignin, 16-20% of magnesium chloride and the balance aluminum chloride. The antistatic injection molding material is excellent in antistatic performance and prevents static generation of electronic parts in use, and accordingly service life prolonging and utilization safety improving can be realized.

Description

Technical field [0001] The invention relates to an injection molding material, in particular to an antistatic injection molding material for preparing electronic parts. Background technique [0002] The so-called injection molding refers to a method of injecting heated and molten materials into a mold, and then cooling and solidifying to obtain a molded product. The specific process is: feeding granular or powdered plastic from the hopper of the injection molding machine into the heated barrel. It is heated and plasticized into a molten state, and then pressurized and injected into the closed mold cavity through a nozzle, and then cooled and hardened to maintain the shape given by the mold cavity. After the mold is opened, the colloid can be taken out. At present, there are more injection molding materials on the market. It is mostly used to prepare electronic parts, which requires high anti-static performance of injection molding materials, while traditional injection molding ma...

[0002] The so-called injection molding refers to the method of injecting the heated and molten material into the mold, and obtaining the molded product after cooling and solidification. The specific process is: feeding granular or powdery plastic from the hopper of the injection molding machine into the heated barrel, It is heated and plasticized into a molten state, and then injected into the closed mold cavity through the nozzle under pressure, and then cooled and hardened to maintain the shape given by the mold cavity. After opening the mold and taking out the colloid, there are relatively few injection molding materials on the market. It is mostly used to prepare electronic parts, which requires high anti-static performance of injection molding materials, and traditional injection molding materials have been difficult to meet people's needs now
