Problems solved by technology

Carcinogenic sodium nitrite is generally used as the main anti-rust agent in the formula of ordinary anti-rust water. At the same time, the dosage is relatively large, which is not conducive to environmental protection and the health of operators. However, the use of humectants to prolong the life of anti-rust water brings The problems of sticky hands and dust are generally only suitable for rust prevention in metal processing processes, and cannot be used for long-term rust prevention; while general dura-coat anti-rust oils are suitable for long-term rust prevention, and the film formation will be transparent and beautiful, but they are often colorless and transparent There are fewer types of resins, and they are not stable, easy to oxidize and change color, and cannot achieve the purpose of decoration
At the same time, this type of resin is expensive, inconvenient to dissolve, and needs to be dissolved in an aromatic solvent, which may cause flammability and explosion; The use of mineral oil is easy to pollute the environment, not easy to biochemically degrade, not conducive to environmental protection, and it is also difficult to remove oil for short-term rust prevention, and the disadvantages of high cost of oil removal

Embodiment Construction

[0016] This water-soluble anti-rust liquid can be prepared in a high-quality stainless steel blending kettle and is stirred by a conventional paddle agitator and speed-regulated by a reducer. Usually, the speed is 50~80r / min, and the blending kettle is heated by a water bath with a jacket. And temperature control.

[0017] The weight ratio of raw and auxiliary materials during preparation is: 5 kg of polyvinyl alcohol with a degree of hydrolysis of 88% and a molecular weight of 300 to 500, 75 kg of deionized water, 0.5 kg of potassium sorbate, 0.1 kg of methylparaben, 0.5 kg of polyvinylpyrrolidone, and triphosphate 0.1kg of butyl ester, 18.3kg of 95% ethanol, 0.4kg of hexamethylenetetramine, and 0.1kg of benzotriazole.

[0018] The preparation process of the water-soluble anti-rust liquid is as follows: put deionized water in a formula quantity into a mixing kettle, and then put polyvinyl alcohol into it while stirring at room temperature to prevent resin agglomeration. When...

Abstract

The invention relates to water-soluble antirust liquid, which comprises the following components by weight: 2-5% of film-forming agent, 0.01-0.5% of film coalescing aid, 0.4-1.0% of antirust complex agent, 0.2-0.8% of preservative, 0.1-0.5% of defoamer, and 92-97.4% of mixed solvent. The water-soluble antirust liquid is a liquid state composition which can be used for many kinds of metal, especially for decorative protection on the metal shiny surface. The composition has the characteristics of high transparency, strong decorative protection and good antirust performance. The product is free from toxicity, extraneous odor and irritation. The liquid is good in film forming property and strong in binding force. The formed film is easily removed (by water), which does not influence the objective gloss of the original metal, so that the water-soluble antirust liquid is particularly suitable for long-term or short-term decorative protection of high-grade products.

Description

technical field [0001] The invention relates to a water-soluble antirust liquid, which can be used for decorative protection and antirust on the surface of various metals (or electroplating layers), and can also be used as a release agent and an antirust agent in the molding process of unsaturated resin. Background technique [0002] Metal surface rust prevention is an important topic in industrial production. Traditional anti-rust oil, anti-rust film, anti-rust water, etc. have their own characteristics, but also have many shortcomings. Carcinogenic sodium nitrite is generally used as the main anti-rust agent in the formula of ordinary anti-rust water. At the same time, the dosage is relatively large, which is not conducive to environmental protection and the health of operators. However, the use of humectants to prolong the life of anti-rust water brings The problems of sticky hands and dust are generally only suitable for rust prevention in metal processing processes, an...
