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

Abstract

The invention discloses electroconductive color slurry and a low-resistance polyurethane material thereof. The electroconductive color slurry is prepared from the following raw materials in parts by weight: 35-55 parts of carbon powder, 30-60 parts of ionic liquid and 0.2-1 part of dispersant. The low-resistance polyurethane material is prepared from the following raw materials in parts by weight: 100 parts of polyester polyol, 0.8-9 parts of electroconductive color slurry, 100-120 parts of isocyanate and 0.5-3 parts of catalyst. 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 elastomers and polyurethane foams (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, talcum powder and base resin after grinding and mixing. It is an auxiliary agent commonly used in the preparation of polyurethane materials. Adding this additive can give polyurethane materials a uniform black tone. However, when used to produce antistatic materials, the black color paste is added at the same time as 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 color...
