The invention discloses a solvent-free static-electricity conducting paint and a preparing method. The solvent-free static-electricity conducting paint comprises 1 part of liquid A and 0.2-0.35 part of liquid B. The liquid A is prepared from, by weight, 50%-65% of polyester resin, 14%-23% of mica powder, 20%-30% of conductive powder, 1%-3% of titanium dioxide and 0.005%-0.01% of fumed silica, wherein the sum of the weight percents of the components of the liquid A is 100%. The liquid B is polyisocyanate. The polyester resin serves as a base material, the conductive powder and other pigment filler are used in cooperation, and the solvent-free static-electricity conducting paint is formed; curing and film forming of the solvent-free static-electricity conducting paint are achieved in the mode that the solvent-free static-electricity conducting paint is reacted with the polyisocyanate to generate polyurethane, and the adopted polyester resin only contains ester bonds and does not contain ether ponds; as the ether bonds are easy to decompose after being exposed in light, the weather resistance is good; as the resin is low in acid value and viscosity, the resin can be prepared into a solvent-free paint, the weather-resistance static-electricity conducting paint can be prepared after the static-electricity conductive powder is added, powdering and falling of a coating can be avoided, and the static-electricity conducting effect of a tank with a coating formed by the solvent-free static-electricity conducting paint is guaranteed.
Description
technical field [0001] The invention relates to the technical field of coatings, in particular to a solvent-free static conductive coating and a manufacturing method. Background technique [0002] Static conductive coatings are a kind of anti-corrosion coatings with static conductive properties mainly made by adding antistatic agents or conductive fillers. Epoxy conductive coatings are currently used more and are relatively mature products. Epoxy electrostatic conductive coating is prepared by adding electrostatic conductive fillers to epoxy resin. Since the ether bond in epoxy resin is decomposed by light, the anti-ultraviolet aging resistance is poor, and it is easy to pulverize when there is light. . As the liquid level of the crude oil floating roof tank drops, the inner wall of the tank may be exposed to the atmospheric environment. After a period of light, the coating will be powdered or even peeled off. When the liquid level in the tank rises again, the coating will ...
