Problems solved by technology

Most of the existing water-based antirust agents contain sodium nitrite or other inorganic and organic salts. Nitrite is harmful to human health, and other inorganic salts (such as chromate and molybdate) will cause environmental pollution. and non-renewable resource consumption, the anti-rust effect of water-soluble organic salts (such as sodium benzoate) is not good
Lanolin and lanolin magnesium soap can only be used as components of anti-rust oil because they are insoluble in water, while oil-soluble anti-rust agents consume a large amount of petroleum resources and have potential safety hazards

Embodiment 1

[0011] Mix 125 grams of lanolin and 125 grams of triethanolamine in a reactor, raise the temperature to 110-120°C, stir and keep this temperature for 60 minutes, stop heating, and add pure water to 1000 grams when the temperature drops to 50-60°C , Stir evenly for 10 minutes, that is, a multi-functional anti-rust and cleaning agent is produced.

[0012] The finished product is made into a 3% solution with tap water, and the corrosion and antirust test is carried out according to GB / T6144-2010, and the detergency test is carried out according to QB / T2117-1995. The results are as follows: the corrosion and anti-rust test of grade one gray cast iron is better than grade A, and the cleaning power is more than 90%.

Embodiment 2

[0014] 80 grams of lanolin and 170 grams of triethanolamine are mixed in a reactor, and by the conditions of Example 1, 1000 grams of multifunctional antirust and cleaning agent finished products are prepared.

[0015] Finished product is made into 3% solution with tap water, carries out corrosion and antirust test and detergency measurement by the method for embodiment 1. The results are as follows: the corrosion and anti-rust test of grade one gray cast iron is better than grade A, and the detergency is more than 92%. In addition, the 45# steel sheet and cast iron sheet were soaked in the 3% solution (as an anti-rust aqueous solution), and the results showed that after 180 days, they still maintained a good metallic luster and no rust occurred.

Embodiment 3

[0017] 62.5 grams of lanolin and 187.5 grams of triethanolamine are mixed in a reactor, and according to the conditions of Example 1, 1000 grams of multifunctional antirust and cleaning agent finished products are prepared.

[0018] Finished product is made into 3% solution with tap water, carries out corrosion and antirust test and detergency measurement by the method for embodiment 1. The results are as follows: the corrosion and anti-rust test of grade one gray cast iron is better than grade A, and the detergency is more than 94%.

Abstract

The invention provides a multifunctional metal water-based antirust cleaning agent, and a preparation method and application thereof. The multifunctional metal water-based antirust cleaning agent disclosed by the invention is characterized by comprising 20-80wt% of wool fat and alkylol amine, and the balance of water, wherein the weight ratio of the wool fat to the alkylol amine is 1 to (1-3). The preparation method disclosed by the invention is characterized by comprising the following steps: mixing the wool fat with the alkylol amine in a reaction kettle, heating to 120+ / -10 DEG C, agitating and keeping the temperature for 60+ / -10 minutes; and stopping heating and cooling to 50-60 DEG C, and then adding quantitative water to the reaction kettle to evenly agitate. The multifunctional metal water-based antirust cleaning agent disclosed by the invention is suitable for metal processing, and metal rust protection and cleaning in the machinery manufacturing industry, and being used as an anti-rust additive.

Description

technical field [0001] The invention relates to a metal water-based antirust and cleaning agent, a preparation method and application thereof. Background technique [0002] In the metal processing and machinery manufacturing industries, anti-rust agents must be used to treat metals, and cleaning agents for steel materials must contain anti-rust components to avoid rust during the cleaning process. Most of the existing water-based antirust agents contain sodium nitrite or other inorganic and organic salts. Nitrite is harmful to human health, and other inorganic salts (such as chromate and molybdate) will cause environmental pollution. and non-renewable resource consumption, the anti-rust effect of water-soluble organic salts (such as sodium benzoate) is not good. Lanolin and lanolin magnesium soap can only be used as components of anti-rust oil because they are insoluble in water, while oil-soluble anti-rust agents must consume a large amount of petroleum resources and have ...
