Problems solved by technology

[0003] The technical problem to be solved by the present invention is that adding low-molecular antistatic agents to the color paste in the prior art is not enough to improve the antistatic performance of polyurethane materials, and excessive addition of color pastes with antistatic agents will easily affect the physical properties of polyurethane materials. To overcome the defects in mechanical properties, provide a conductive color paste that can obtain good antistatic performance with a small amount of addition

The electroconductive color slurry provided by the invention has low addition amount and good electrical conductivity; and the low-resistance polyurethane material provided by the invention is applicable to dust-free room and other clean places, and has good antistatic property, low humidity dependence and good physical and mechanical properties.

Description

technical field [0001] The invention relates to a color paste and a polyurethane material using the color paste, in particular to a conductive color paste and a low-resistance polyurethane material thereof. The color paste can be widely used in polyurethane microcellular elastomer and polyurethane foam (foam density > 0.05g / cm 3 ), effectively reducing the volume resistance of elastomers and foams. Background technique [0002] Black color paste is generally made of carbon black, talc powder and base resin after grinding and mixing. It is an auxiliary agent commonly used in the preparation of polyurethane materials. Adding this auxiliary agent can give polyurethane materials a uniform black tone. However, when used in the production of antistatic materials, black colorants are added together with commonly used low molecular antistatic agents, but the antistatic effect of polyurethane materials is not good and is highly dependent on humidity. Increasing the amount of col...
