Abstract

The invention discloses a method for preparing a polyurethane-polydiphenylamine antistatic material, and the polyurethane-polydiphenylamine antistatic material is prepared from diphenylamine, sodium dodecyl benzene sulfonate, (NH4) 2S2O8, triphenylmethane triisocyanate, ethanol, propylene glycol and other raw materials by combination of vacuum distillation, ice water bath, acid treatment and other methods. The material prepared by the method has very good antistatic performance.

Description

technical field [0001] The invention relates to a preparation method of a polyurethane-polydianiline antistatic material, which belongs to the field of antistatic. Background technique [0002] At present, the main antistatic methods of polymers include: adding antistatic agents; filling conductive fillers such as carbon black, metals, metal oxides, and inorganic salts; blending with hydrophilic polymers or conductive polymers, etc. Although the addition of antistatic agents or inorganic conductive powders to polyurethane materials has a certain antistatic effect, the antistatic durability is poor, and the material performance also decreases to a certain extent. I have invented a method for preparing polyurethane-polydianiline antistatic materials. The method is simple, and the prepared polyurethane-polydianiline antistatic materials have good antistatic effect and good durability. Contents of the invention [0003] Aiming at the above-mentioned problems in the prior art,...
