Embodiment 1
[0013] Embodiment 1: prepare the antirust liquid of 100 parts by weight
[0014] Take by weighing 91.7 parts of weight of deionized water, add 1.8 parts of weight of sodium molybdate, stir and dissolve; add 2.8 parts of weight of zinc gluconate, stir and dissolve; add 1.9 parts of weight of sodium benzoate, stir and dissolve; add 1.8 parts of weight of Glycerin, stirred and mixed to obtain a water-soluble antirust solution.
[0015] Brush the prepared water-soluble anti-rust solution on the newly processed and oil-free steel plate substrate surface for anti-rust treatment, and no obvious rust marks were found after being placed indoors for 40 days.
Embodiment 2
[0016] Embodiment 2: prepare the antirust liquid of 100 parts by weight
[0017] Weigh 91.9 parts by weight of deionized water, add 2 parts by weight of sodium molybdate, stir and dissolve; add 4 parts by weight of zinc gluconate, stir and dissolve; add 2 parts by weight of sodium benzoate, stir and dissolve; add 0.1 parts by weight of Carboxymethyl cellulose, stirred and mixed to obtain a water-soluble antirust solution.
[0018] Brush the prepared water-soluble anti-rust solution on the newly processed and oil-free steel plate substrate surface for anti-rust treatment, and no obvious rust marks were found after being placed indoors for 25 days.
Embodiment 3
[0019] Embodiment 3: prepare the antirust liquid of 100 parts by weight
[0020] Weigh 92.2 parts by weight of deionized water, add 3.7 parts by weight of sodium molybdate, stir and dissolve; add 1 part by weight of zinc gluconate, stir and dissolve; add 1 part by weight of sodium benzoate, stir and dissolve; add 2.1 parts by weight of Glycerin, stirred and mixed to obtain a water-soluble antirust solution. .

Abstract
The invention discloses a water-soluble antirust solution between processes, which is composed of the following raw materials in parts by weight: 5-8 parts by weight of sodium molybdate, 2-4 parts of zinc gluconate, 1-2 parts of sodium benzoate, and 2-4 parts of glycerin , sodium carboxymethyl cellulose 0.1-0.2, deionized water 80-90. The water-soluble antirust liquid provided by the invention does not contain highly toxic substances such as sodium nitrite, dichromate or volatile organic amines, nor does it contain phosphate and nitrate components that make water eutrophication, and has low toxicity , has a certain degree of environmental protection; when the antirust solution provided by the invention is used to prevent rust on steel parts, no rust marks will be generated within 20 to 40 days, which can meet the requirements of antirust between processes and short-term storage of ordinary steel workpieces , and can be easily removed by washing with water, and has the advantages of low cost and convenient preparation.
Description
technical field [0001] The invention mainly relates to an antirust liquid, in particular to a water-soluble antirust liquid between processes. Background technique [0002] Iron and steel products generally need to be processed through multiple processes. The semi-finished products will be rusted due to the influence of processing media, humid air and hand sweat during transportation and storage between processes. Therefore, temporary inter-process protection is often required. Rust, in which the use of anti-rust liquid coating the surface of the workpiece is a common method. The anti-rust liquid includes water-based anti-rust liquid with water as the dispersion medium and oil-based anti-rust liquid with mineral oil as the dispersion medium (that is, anti-rust oil). Oil-based anti-rust liquid is mainly composed of mineral oil and oil-soluble corrosion inhibitor. When it is applied on the surface of steel parts, it is difficult to clean and remove; if it is not cleaned, it w...
