Abstract

The invention disclose an ultraviolet-curable high-transparency permanent antistatic coating which contains an oligomer of (methyl) acrylate, a monomer of (methyl) acrylate, a photoinitiator, an antistatic agent and other surface additives, wherein the antistatic agent is a reactive type alkyl nitrogen onium salt type organic matter or a mixture thereof; the antistatic coating is easy to process and apply, and the obtained coating layer is still capable of keeping excellent antistatic property under a low humidity condition; the additives do not affect the chroma and the transparency of the formed coating layer, separation, white-turning, yellowing and the like are prevented under mal-conditions such as a high temperature and a high humidity and the antistatic property of the coating layer is in the range from 108 to 1010 ohm / cm<2>; as a result, the ultraviolet-curable high-transparency permanent antistatic coating is capable of meeting general antistatic requirements, and applicable to treatment of surface antistatic coating layers of an optical thin film, a packaging thin film, high-grade carpentry, an automobile and the like which have high requirements for light transmission, color and luster, gloss, weather fastness and environmental protection.

Description

technical field [0001] The invention relates to an antistatic paint, in particular to a UV-cured, highly transparent and permanent antistatic paint. Background technique [0002] In recent years, in the fields of automobiles, high-end solid wood furniture, lighting fixtures, electronic and electrical packaging, optical moldings, printing, etc., more and more materials are required for antistatic functional coatings to prevent electrostatic adsorption of dust or dust generated during production activities. Injury to staff, etc. [0003] It is known that an antistatic layer is usually applied to the surface of the finished product. The antistatic layer is usually coated on the surface of the article by a coating containing conductive fillers such as conductive metal oxides, nano-metal powders, metal sols, and nano-carbon blacks, or conductive polymer dispersions, ionic liquids, and surfactants. Cloth is formed after curing. The use of this type of antistatic coating usually...
