preparation example Construction

[0016] The invention provides a method for preparing a metal degreasing agent. The method is as follows: the raw materials are respectively placed in containers according to the required dosage, and dissolved in water respectively. The amount of water should be able to melt the raw materials. The optimum temperature for water dissolution is:

[0017] (1) Anionic surfactant and nonionic surfactant are dissolved in hot water at 60-90°C, stirred evenly to obtain mixed solution 1;

[0018] (2) Other substances are dissolved in warm water at 25-50°C, and stirred evenly to obtain mixed solution 2;

[0019] Mix mixed solution 1 and mixed solution 2 evenly, and adjust to the required concentration with water.

[0020] The present invention also provides a degreasing method. The metal material is immersed in a degreasing agent for ultrasonic degreasing for 1-3 minutes, wherein the degreasing agent is the degreasing agent described in the present invention.

Embodiment 1

[0023] 1. Preparation method of degreasing agent

[0024] (1) Dissolve 400 g of triethanolamine oleic acid soap, 120 g of coconut oil fatty acid diethanolamide (6502), and 80 g of fatty alcohol polyoxyethylene ether (AEO) in 150 g of hot water at 80° C., and stir evenly to obtain a mixed solution 1;

[0025] (2) Dissolve 50 g of sebacic acid, 50 g of lauric acid, and 50 g of n-butanol with 70 g of warm water at 40° C., and stir evenly to obtain a mixed solution 2;

[0026] Mix mixed solution 1 and mixed solution 2 evenly, add 30 g of water to adjust to 1000 g, and obtain degreasing agent A1.

[0027] 2. Degreasing

[0028] Take an appropriate amount of degreasing agent A1, add water 15 times the weight of the degreasing agent to it to dilute the degreasing agent, and immerse the aluminum alloy in the diluted degreasing agent at 70°C for ultrasonic degreasing for 3 minutes.

[0029] After washing, drying and other processes, the surface of the product has no oil stains and no...

Embodiment 2

[0031] 1. Preparation of metal degreaser

[0032] (1) Dissolve 500g of polyoxyethylene sodium lauryl sulfate, 100g of coconut oil fatty acid diethanolamide (6501), 50g of fatty alcohol polyoxyethylene ether (Pingpingjia) in 70g of hot water at 80°C, and stir evenly to obtain a mixed solution 1 ;

[0033] (2) 30 g of sodium benzoate, 60 g of phytic acid, 2 g of lauric acid, 1 g of adipic acid, and 100 g of ethanol were dissolved in 30 g of warm water at 30° C., and stirred evenly to obtain a mixed solution 2;

[0034] Mix mixed solution 1 and mixed solution 2 evenly, add 57g of water to adjust to 1000g, and obtain degreasing agent A2.

[0035] 2. Degreasing

[0036] Take an appropriate amount of degreasing agent A2, add water 18 times the weight of the degreasing agent to it to dilute the degreasing agent, and immerse the stainless steel in the diluted degreasing agent at 70°C for ultrasonic degreasing for 3 minutes.

[0037] After washing, drying and other processes, the su...

Abstract

The invention provides a metal deoiling agent. The deoiling agent contains anionic surfactant, nonionic surfactants, solubilizer and corrosion inhibitor, wherein corrosion inhibitor contains monocarboxylic acid and dicarboxylic acid and the weight ratio of monocarboxylic acid to dicarboxylic acid is 10-1:1. The invention also provides a deoiling method. The deoiling method is as follows: soaking a metal material in the deoiling agent to perform ultrasonic deoiling for 1-3min, wherein the temperature of the deoiling agent is 50-80 DEG C and the metal deoiling agent is the metal deoiling agent in the claim 1. The deoiling agent of the invention can be used to effectively remove greasy dirts on the surface of metal in a short time can not corrode metal; and the deoiling agent has simple formula, low cost and stable performance.

Description

technical field [0001] The invention relates to a metal degreasing agent and a degreasing method. Background technique [0002] Cleaning and degreasing processes are often used in the process of metal production and processing. Various metal degreasers that are often used at present mainly include strong acids, strong alkalis and surfactants. They are generally aimed at the treatment of light oil stains on the metal surface. The cleaning efficiency of heavy oil stains is low, which is reflected in the long cleaning time and poor effect; there are many foams, which affect the effect of degreasing and cleaning after degreasing; Toxic and harmful substances such as sodium nitrite, etc., pollute the environment and cause harm to the operator's body; they are easy to cause corrosion to more active metals such as aluminum, which affects subsequent processing. Contents of the invention [0003] The technical problem to be solved by the present invention is the defect of low deg...
