Problems solved by technology

Generally, 15% to 25% of carbon black needs to be filled in the ABS resin matrix to give it antistatic and conductive functions, and only when the distance between adjacent carbon black particles is 1.5-10nm, the two particles can conduct each other. When the distance between two adjacent carbon black particles is about 0.35nm, the contact between particles can be approximated as the contact of pure particles, but the high filling of carbon black will lead to poor processability of composite materials, melting The bulk viscosity increases, the mechanical properties of the material are reduced, and the carbon black particles are easy to fall off from the composite system, which makes the material resistivity difficult to control, etc.

Description

technical field [0001] The invention relates to a preparation method of an antistatic material, in particular to an antistatic flame-resistant ABS resin material and a preparation method thereof. Background technique [0002] Surface resistivity is an important index to measure the ability of materials to disperse electrostatic charges. It is generally believed that when the surface resistivity is 10 10 ~10 11 Below Ω·cm, the material has good antistatic and accumulation capabilities. Usually, most polymer materials have the characteristics of good electrical insulation and small dielectric constant, and generally belong to non-conductors, and their volume resistivity is about 10. 10 ~10 20 Ω·cm, so in the process of use, the surface generates static electricity accumulation through friction, contact, etc., and the accumulated charge is difficult to eliminate, which is easy to cause electrostatic discharge, and eventually causes a series of hazards, such as component def...
