Anti-static anti-corrosive paint using aluminum triphosphate/nano-silver compound electric conducting powder

Abstract

The invention relates to the field of the chemistry and chemical engineering, and aims to provide anti-static anti-corrosive paint using aluminum triphosphate / nano-silver compound electric conductingpowder. The paint is formed by double components A and B, wherein the component A is formed by the following raw materials: water-borne epoxy resin, the aluminum triphosphate / nano-silver compound electric conducting powder, titanium dioxide, barium sulfate, talcum powder, a dispersing agent, a defoaming agent, dipropylene glycol methyl ether, propanediol butyl ether and deionized water; and the component B is an epoxy hardener, and a weight of the component B accounts for 5-8% of a weight of the component A. In the paint, the aluminum triphosphate / nano-silver compound electric conducting powder is an important component for bringing an anti-static function. A preparation technology for the powder is simple without a high-temperature process, energy is saved, used raw materials are non-toxic without polluting the environment, the powder is stable in performance, and small in electrical resistivity, and has the rust-proof and anti-corrosion functions. Compared with current conventional metal anti-corrosive paint, the paint is low in electrical resistivity, has the anti-static function, and continuously keeps good corrosion resistance.

Description

technical field [0001] The invention relates to an antistatic anticorrosion paint using aluminum tripolyphosphate / nano-silver composite conductive powder, which belongs to the field of chemical industry. Background technique [0002] Metal materials occupy an important position in the field of materials due to their excellent mechanical properties and process properties, but metal corrosion has also caused huge losses to human society, such as storage and transportation equipment made of metal materials, petrochemical equipment, steel workshops, ships, Construction machinery, etc., are damaged due to long-term chemical or electrochemical effects, causing a large amount of economic losses. Aiming at the problem of metal corrosion, a variety of technologies can be used to protect, slow down or prevent metal corrosion. The most effective and common method is to coat the metal surface with an anti-corrosion coating to isolate the corrosive medium from contacting the metal substr...
