Abstract

The invention discloses an inorganic zinc-rich antirust skid-resistant coating which consists of a component A, a component B and a component C, wherein the component A consists of 40-40 parts of solvent, 3-6 parts of water and 30-50 parts of ethyl silicate; the component B consists of 20-30 parts of toughened resin, 5-10 parts of accessory ingredient, 40-60 parts of zinc powder, 30-40 parts of corundum and 5-10 parts of solvent; the component C is aluminum powder; and the mixing mass ratio of the component A to the component B to the component C is (1-3):(2-5):(0.2-0.5). According to the inorganic zinc-rich antirust skid-resistant coating, ethyl silicate hydrolysate, namely silanol is adopted to react with zinc powder and active iron on the surface of a steel product so as to generate zinc silicate and zinc-silicic acid-iron compound; due to such chemical bond joint, a certain adhesive force between the coating and the steel product is achieved; a zinc standard electrode is smaller than a ferric standard electrode and loses electrons easily, so that an anode can be sacrificed, and iron is prevented from being eroded; and irregular anti-skid grains are added into the coating, so that the surface roughness of the coating is properly increased, other objects are obstructed or prevented from sliding on the upper surface of the coating, so that an anti-skid effect is achieved.

Description

technical field [0001] The invention relates to a coating in the chemical industry, in particular to an inorganic zinc-rich anti-rust and anti-slip coating with excellent anti-rust and anti-skid properties. Background technique [0002] In recent years, with the rapid development of the national economy and the continuous growth of the iron and steel industry, the scale of my country's infrastructure construction has expanded, and the protective coating of many large government projects, key projects, and large steel bridges has become an important topic in the field of anti-corrosion engineering. . Especially in the anti-corrosion coating of the friction surface of the bolted and welded beam joints of ships, bridges and other steel facilities, it is necessary to use coatings with excellent anti-rust and anti-slip properties; inorganic zinc-rich anti-rust and anti-slip coatings are special coatings with excellent anti-rust properties Anti-slip performance, as an inorganic z...
