Abstract

The invention discloses a mineral-filled permanent antistatic PC / PBT composite material and a preparation method thereof, and belongs to the technical field of polymer material modification. The mineral-filled permanent antistatic PC / PBT composite material comprises the following components in parts by weight: 45-55 parts of PC, 5-55 parts of PBT, 0-10 parts of talcum powder, 0-22 parts of a permanent antistatic agent, 0-5 parts of a flexibilizer, 0-0.5 part of an antioxidant, 0.2 part of a transesterification inhibitor and 1 part of black masterbatch. The talcum powder with high purity is adopted to improve the rigidity and dimensional stability of the whole PC / PBT material, and the permanent antistatic agent is added to make the whole material more accord with the ergonomic requirements in the application process, so the comfort degree of the human body is improved, the electrostatic damage generated when the human body contacts parts is reduced, and the application range of the material is expanded.

Description

technical field [0001] The invention relates to the field of polymer material modification, in particular to a mineral-filled permanent antistatic PC / PBT composite material and a preparation method thereof. Background technique [0002] PC / PBT alloy material combines the excellent properties of polycarbonate and acrylonitrile-butadiene-styrene. Among them, PC (polycarbonate) is a general engineering plastic with excellent mechanical properties and electrical properties. And heat resistance, especially known for its excellent impact strength and creep resistance, high light transmittance, low water absorption, stable product size, has become the fastest growing general engineering plastic among the five engineering plastics; and PBT (for Butylene phthalate) material, the molecular structure is highly symmetrical, has a certain crystal orientation ability, has high film-forming properties, and PBT plastic has good friction resistance, low wear and high hardness, good electrica...
