All-weather persistent antistatic master batch capable of being subjected to thermoplastic processing and antistatic composite material

Abstract

The invention belongs to the field of preparation of macromolecular composite materials and particularly relates to an all-weather persistent antistatic master batch capable of being subjected to thermoplastic processing and an antistatic composite material. The antistatic master batch is prepared by forming of a low-dissociation-energy compounding agent, a processing auxiliary agent and thermoplastic macromolecular resin containing polar groups through macromolecular thermoplastic processing equipment at the temperature of 25-300 DEG C; and the mass ratio of the compounding agent to the thermoplastic macromolecular resin is equal to (1:10)-(1:50). The invention also discloses the antistatic composite material which is obtained after the persistent antistatic master batch and a macromolecular base material are formed through the thermoplastic processing equipment. The antistatic composite material has the characteristics that: 1. the antistatic composite material has light color and dyeability; 2. The master batch of the antistatic composite material and the compounding agent are wider in selection range, low in cost and easy to obtain, and the production process is simple, safe and non-hazardous; and 3. the influence of the ambient environment on the antistatic performance of the antistatic composite material is less, and the antistatic performance is persistent.

Description

technical field

[0001] The invention belongs to the field of preparation of polymer composite materials, and in particular relates to an all-weather durable antistatic masterbatch and antistatic composite material which can be thermoplastically processed. Background technique

[0002] The surface resistance of most polymers is as high as 10 14 ~10 17 ohm / sq, a lightweight material with excellent insulating properties. Therefore, during the processing and transportation of polymer materials, the charge balance on the surface of the material will be broken due to friction, and the surface will generate a certain amount of static electricity due to charge gain and loss. However, high surface resistance often brings greater electrostatic hazards to polymer materials during use, often leading to dust collection on the surface of products, electrostatic breakdown and short circuit of circuit boards. It may even cause fire or explosion due to electrostatic discharge, which will ...
