Two-acid non-yellow smoke polishing additive and polishing liquid

Abstract

The invention proposes a two-acid non-yellow smoke polishing additive, including 15-35 parts of ethylene thiourea, 25-45 parts of benzotriazole, 10-15 parts of iron sulfate, 1-5 parts of nickel sulfate, and 20 parts of ammonium molybdate. ~40 parts and 5~15 parts of sodium molybdate. The polishing process using the two-acid smoke-free polishing additive of the present invention will not produce nitrogen oxide yellow smoke and other gas pollutants, and its components are environmentally friendly; the surface gloss of the polished product is above 700 degrees, the gloss is uniform, and the mirror effect is very good Good; lower temperature requirement for polishing operation, less energy consumption, energy saving and environmental protection.

Description

technical field [0001] The invention relates to the technical field of metal surface processing, in particular to a two-acid yellow-smoke-free polishing additive and a polishing liquid based thereon. Background technique [0002] Polishing agent, commonly known as brightener, light yellow or yellow transparent liquid preparation, suitable for polishing various metal or alloy products. According to market demand, preparations for different materials have been continuously evolved, such as stainless steel polishing agent, magnesium alloy polishing agent, copper polishing agent Agent, aluminum alloy polishing agent, glass polishing powder, research polishing powder, etc. As metals or alloys are more and more widely used in daily life, metal or alloy products need to be treated to obtain a more beautiful appearance, and in the automatic production process, surface treatment methods such as chemical polishing are generally used. Traditional polishing additives require three-acid...

AI Technical Summary

Problems solved by technology

Traditional polishing additives require three-acid chemical polishing formula, which contains nitric acid, nitrate or nitrite, and its ingredients cause serious harm to the environment, and when polishing operations produce smoke, odor, and even toxic gases, it is very harmful to the human body. The production process needs to increase the purification equipment, the production cost is high, the temperature required for the polishing operation is high, and the energy consumption is large

At present, most of the domestic and foreign research formulas for smokeless chemical polishing agents used for aluminum alloy surface polishing use the combination of phosphoric acid, sulfuric acid and polishing additives, or use phosphoric acid, sulfuric acid, Al 3+ However, there are still some shortcomings and deficiencies in the prior art polishing additives, such as complicated maintenance of the bath solution of polishing additives, low or uneven polishing gloss, etc.
