Anti-abrasive and anticorrosive paint for metal and preparation method of paint

Abstract

The invention discloses an anti-abrasive and anticorrosive paint for metal and a preparation method of the paint. The paint is prepared from, by weight, 40-60 parts of copolymer of styrene and acrylic acid, 10-20 parts of styrene butadiene rubber, 10-15 parts of inorganic filler, 5-15 parts of EVA abrasion-resistant agent, 2-5 parts of wetting dispersant h-9040, 3-8 parts of petroleum resin modified wax emulsion, 2-10 parts of gaseous titanium dioxide, 1-4 parts of zinc oxide, 0.5-1 part of phosphonic carboxylic acid, 1-2 parts of 1.5% phytic acid, 0.5-1 part of lignosulfonate, 1-3 parts of anti-flash-rust agent, 2-6 parts of propylene glycol, 2-6 parts of film-forming agent, and 15-25 parts of water. The invention further discloses a preparation method of the anti-abrasive and anticorrosive paint for metal. The paint obtained according to the raw material formula and the preparation method has good metal anti-corrosion property, environmental friendliness, and abrasion resisting property; the service life and the anti-corrosion period of the paint are prolonged; therefore, the cost is reduced, the work intensity is lowered, and the anti-corrosion efficiency is improved.

Description

technical field [0001] The invention relates to a coating, in particular to a wear-resistant anti-corrosion coating for metal and a preparation method thereof. Background technique [0002] Corrosion of metals is a phenomenon in which metals are damaged by electrochemical or chemical effects of environmental media. Metal corrosion pervades all areas of the national economy and has brought huge losses to the national economy. In industrially developed countries, the direct economic loss caused by metal corrosion accounts for 1% to 4% of the total output value of the national economy, and the annual rusted steel due to corrosion accounts for about 20% of the total output, and about 30% of the equipment is due to metal corrosion. Corroded and scrapped. In China, the annual economic loss due to metal corrosion accounts for 4% of the gross national product. Because of this, metal anti-corrosion coatings with excellent rust resistance and chemical medium corrosion resistance ha...

AI Technical Summary

Problems solved by technology

Due to the wide use of metal products, many metal products have been subjected to friction tests for a long time. If anti-corrosion coatings are not coated, the service life of metal products will be greatly reduced due to metal corrosion and friction. Coating anti-corrosion coatings can reduce corrosion, but the existing Metal anti-corrosion coatings have poor wear resistance. Under high-frequency friction conditions, frequent coatings are required to reduce the corrosion rate of metal products, resulting in high work intensity and low anti-corrosion efficiency.
