Abstract

The invention relates to the technical field of coatings, in particular to an air-drying antistatic coating and a preparation method thereof. The air-drying antistatic coating comprises butyl acetate,diacetone alcohol, xylene, acrylic resin, a dispersing agent, conductive powder, a leveling agent, an anti-settling agent and propylene glycol methyl ether acetate, wherein the acrylic resin can meetthe adhesion of most plastic materials, in addition, flocculent carbon nanotubes are used as a conductive carrier and are easy to grind, the resistance of the carbon nanotubes can be controlled by controlling the grinding particle size and increasing or decreasing the use amount, and wax dispersion liquid is used as an anti-settling agent in the formula and can prevent the coating from settling in a tank. The air-drying antistatic coating is good in leveling property, free of obvious wrinkling orange peel, free of obvious sagging accumulation edges, high in scratch resistance, high in dryingspeed, capable of choosing to be baked or non to be baked in the using process and capable of meeting the requirements of different users.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a self-drying antistatic coating and a preparation method thereof. Background technique [0002] With the rapid development of science and technology and the increasingly diversified and individualized electronic products, the demand for anti-static plastic products is becoming more and more obvious. However, the anti-static coatings in the prior art are used in a small range and have a long drying time, which cannot meet the requirements. Market demand. Contents of the invention [0003] One of the objectives of the present invention is to provide a self-drying antistatic coating for the deficiencies of the prior art. The self-drying antistatic coating is suitable for most plastic materials, has a fast drying speed, and is suitable for different customer requirements.
