Abstract

The present invention discloses an aqueous rotating rust steel iron surface treatment liquid and a preparation method thereof, and belongs to the technical field of anti-corrosion coating materials, wherein the aqueous rotating rust steel iron surface treatment liquid comprises, by mass, 75-80% of an aqueous acrylic acid anti-rust emulsion, 0.2-0.4% of an auxiliary agent, 1.5-5% of tannin acid, and 15-20% of deionized water. According to the present invention, the aqueous rotating rust steel iron surface treatment liquid does not contain organic solvents, has characteristics of no toxicity, no harm, fire retardation, explosion resistance and no pollution, and meets the energy saving, emission reducing and green ecological direction; the construction performance of the aqueous rotating rust steel iron surface treatment liquid is good (fast-drying) and no obstruction exists so as to further improve the resistance of the external coating (strong adhesion and high paint film hardness); acid washing, phosphorization, sand blasting, shot blasting and other anti-rusting ways are not required to be used on the steel iron substrate, the coating with rust can be performed, and only after the substrate surface is subjected to the flattening treatment, the aqueous rotating rust steel iron surface treatment liquid is coated on the substrate surface so as to complete the operation; and the application prospects of the aqueous rotating rust steel iron surface treatment liquid are broad.

Description

technical field [0001] The invention belongs to the technical field of anti-corrosion coatings, and in particular relates to a water-based self-rotating rusty iron and steel surface treatment solution and a preparation method thereof. Background technique [0002] According to statistics, the annual loss of steel due to corrosion in the world exceeds 10,000 tons, and the cost of steel corrosion protection amounts to hundreds of millions of dollars. In terms of rust removal, most of them use traditional methods such as pickling, phosphating, sandblasting, and shot blasting. , and these traditional rust removal methods have some deficiencies more or less, for example: a large amount of volatilization of harmful gases in the process of pickling and phosphating, which not only damages the health of operators, but also pollutes the surrounding environment; shot blasting and sandblasting The raised fog and dust brought occupational diseases to many operators and caused lifelong su...
