Antistatic floor paint

Abstract

The invention relates to antistatic floor paint. The antistatic floor paint is prepared from modified poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate), aromatic polyurethane acrylate, organic silicone resin, dimethylaminoethyl acrylate, a diluent, a leveling agent, graphene, magnesium chloride, nanometer aluminum powder and organic bentonite. After film formation and curing, the antistatic floor paint film has self-assembling characteristics and can be freely spread on a base so that a high efficiency conductive network is constructed. The antistatic floor paint film has high light transmittance, high conductivity and stability and has a wide application prospect.

Description

technical field [0001] The invention belongs to the field of paint preparation, and in particular relates to a floor paint with antistatic performance. Background technique [0002] Static electricity is a phenomenon of charge accumulation due to contact or friction. In daily life, static electricity will be generated due to climate, environment, and physical influences, and the existence of static electricity will bring harm to metal devices, and even lead to a decrease in stability. Defects such as faults, or serious hazards such as combustion or explosion of metal oil pipelines. [0003] Antistatic coatings are functional coatings that have the ability to conduct electricity and dispel accumulated static charges. Antistatic coatings have been developed along with modern science and technology, and have a history of more than half a century. As early as 1948, the United States published a patent for making conductive adhesive from silver and epoxy resin, which was th...

Problems solved by technology

Among them, the density of metal powder is high, and a large volume fraction is required to form a conductive path. The surface layer is easily oxidized, which will reduce or even lose electrical conductivity, and has poor corrosion resistance, thereby affecting other properties of the coating. Therefore, the application of metal powder as a conductive filler is subject to certain restrictions. Restrictions; antistatic agents have poor temperature resistance, water resistance, oil resistance, corrosion resistance, durability, and unstable antistatic performance; early antistatic coatings generally use carbon-based materials as conductive fillers, and black conductive graphite and carbon black have poor dispersion. The color of the product is black, and it is not easy to adjust to other lighter colors; with the development of science and technology, new conductive fillers such as semiconductor metal oxides and nano-conductive powders have gradually appeared, and have been applied in antistatic coatings. These materials are light in color , easy to color, enrich the color system of antistatic coatings, but when this kind of material is used alone, the addition amount is large, and the dispersion stability is poor, which will affect the performance of the coating and its coating, so it is generally used in conjunction with carbon-based materials
