A kind of preparation technology of antistatic wall paint

Abstract

The invention relates to a preparation process of an antistatic wall paint. First, the modified poly(3,4-ethylenedioxythiophene)-polystyrene sulfonic acid is prepared, and then it is sheared and dispersed at a high speed in a high-speed disperser. Add aromatic urethane acrylate, silicone resin, dimethylaminoethyl acrylate, diluent, leveling agent, graphene, magnesium chloride, nano-silver powder, and organic bentonite into it in turn, stir and mix evenly, and stir for 15-60 minutes to obtain the product. The antistatic wall paint prepared by it has self-assembly characteristics after the film is cured, can spread freely on the substrate, and builds an efficient conductive network, so that the antistatic film has high light transmittance, high conductivity and stability, and has a wide range of applications prospect.

Description

technical field [0001] The invention belongs to the field of wall paint preparation, and in particular relates to a preparation process of antistatic wall paint. 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 wall paint is a functional wall paint that has the ability to conduct electricity and eliminate accumulated static charges. Antistatic wall paint has been developed along with modern science and technology, and has 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,...

Problems solved by technology

Among them, metal powder has a high density, and a large volume fraction is required to form a conductive path. The surface layer is easily oxidized, which will reduce or even lose conductivity, and has poor corrosion resistance, which affects 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 wall paints 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 modulate into 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 wall paints. Light color, easy to color, enriches the color system of antistatic wall paint, but this kind of material is added in a large amount when used alone, and the dispersion stability is poor, which will affect the performance of wall paint and its coating, so it is generally used with carbon Use with materials
