Problems solved by technology

However, PVC is a high-molecular polymer with poor electrical conductivity and is prone to static electricity. In some cases, it can generate thousands or even tens of thousands of volts of static electricity; There are many problems, hidden dangers, losses and even disasters. For example, the electromagnetic field generated by static electricity is very easy to absorb dust like a vacuum cleaner, resulting in product appearance defects; , these weak static electricity cannot be taken away in time, and static sparks are likely to cause fires and even explosions

Abstract

The invention belongs to the technical field of sealing strips for vehicles, and particularly relates to an antistatic sealing strip. The sealing strip comprises the following components in parts by weight: 100 parts of PVC resin, 65-80 parts of a plasticizer, 15-30 parts of ethylene propylene diene monomer, 8-18 parts of calcium carbonate, 8-16 parts of zinc oxide, 8-14 parts of carbon black, 15-25 parts of an antistatic agent, 5-8 parts of a calcium-zinc stabilizer, 0.2-1 part of zinc stearate, 0.5-2 parts of dibenzenesulfonyl hydrazide ether and 1-5 parts of a flame retardant. The antistatic agent is a multi-walled carbon nanotube grafted and modified by an ionic liquid, and the ionic liquid is 1-hydroxyethyl-3-methylimidazolium tetrafluoroborate; the antistatic sealing strip has the beneficial effects that the surface-grafted carbon nanotubes are adopted as the antistatic agent, so that the dispersing performance of the antistatic agent is improved, and the prepared sealing strip is better in antistatic performance and better in color; and the processing manufacturability is better, and the mechanical property is better.

Description

technical field [0001] The invention belongs to the technical field of sealing strips, and in particular relates to an antistatic sealing strip for vehicles and a preparation method thereof.
