Method for preparing corrosion-resistant antistatic coating

Abstract

The invention discloses a method for preparing a corrosion-resistant antistatic coating and belongs to the technical field of coating preparation. When a high polymer material and other non-conductivebase materials is coated with the corrosion-resistant antistatic coating disclosed by the invention, tin powder is first deposited on the surface layer of the base material so as to form a tin metallayer. Therefore, when the tin metal layer is complexed, oxygen and other substances are effectively prevented from entering the metal surface, and a single-molecule hole-electron conductive layer isformed on the covering metal base surface. According to the method disclosed by the invention, mixed coumarin powder, fresh lemon peel and ammonium hydroxide are mixed and fermented to perform acidification precipitation, 2,3-epoxypropyltrimethylammonium chloride is added, the coumarin powder is fermented to produce coumarin, and an effect of promoting cured cross-linking can be achieved. Due to increase of the degree of crosslinking, the ageing degradation ability of resins is decreased, anti-aging and corrosion-resistant effects are achieved, and graphite, carbon black and other highly antioxidant substances can prevent the coating from being corroded. Moreover, the wear resistance and conductivity of the coating are improved, and the application prospects are wide.

Description

technical field

[0001] The invention discloses a method for preparing a corrosion-resistant and antistatic coating, which belongs to the technical field of coating preparation. Background technique

[0002] The name of conductive coatings includes antistatic coatings and antistatic coatings. According to a series of standards formulated by the country, conductive coatings are used. From the design of industrial buildings and equipment, conductive coatings are used. From the functional analysis of coatings, coatings can be used in 2~ In a short period of 10 seconds, discharge static voltage accumulation to avoid accidents that cause fire or damage electronic components due to discharge. The generation and accumulation of static electricity is an objective existence in nature and has no resistance skills. It has not been tested for fabrics. The antistatic agent product based on the theory of leakage can prevent the accumulation of static electricity during the wearing process ...
