Abstract

The invention discloses high-efficiency antistatic coating, which is prepared from the flowing components in parts by weight: 60 to 80 parts of matrix resin, 40 to 60 parts of acrylate polymer emulsion, 5 to 8 parts of polyisocyanate curing agent, 5 to 12 parts of carbon nano tube, 5 to 10 parts of nanosilicon dioxide, 10 to 15 parts of ground calcium carbonate, 3 to 5 parts of graphite powder, 2 to 4 parts of wetting agent, 3 to 5 parts of coupling agent, 0.5 to 1.5 parts of methyl ethyl ketoxime, 5 to 10 parts of film-forming agent and 3 to 5 parts of leveling agent. According to the high-efficiency antistatic coating disclosed by the invention, through the reasonable formulation design, the obtained antistatic coating has excellent antistatic property when the usage amount of an antistatic agent (carbon nano tube) is relatively lower, has excellent mechanical property, and has wide application prospect.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a high-efficiency antistatic coating. Background technique [0002] Antistatic coatings are functional coatings that have the ability to conduct electricity and dispel accumulated static charges. At present, the most commonly used antistatic modification method in industrial applications is to add antistatic agents or use antistatic fillers. In terms of the use of antistatic agents, their antistatic performance is poor and their durability is insufficient; the most commonly used antistatic filler is carbon black, and its disadvantage is that the required amount of addition is too large and the color is dark, which is not suitable for light-colored coating products. Be applicable. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a high-efficiency antistatic coating, which can solve the above-mentioned problems existing in the...
