AI Technical Summary

Problems solved by technology

Water-based cleaning agents containing nitrites have excellent rust resistance, but nitrites are highly toxic and have indirect carcinogenic effects when used together with triethanolamine, while water-based cleaning agents without nitrites are more effective in preventing rust Sexuality is often suboptimal and costly

Embodiment 1

[0064] Calculated in parts by weight, the raw materials of the environmentally friendly water-based EMU special cleaning agent components include:

[0065] 56 parts of nonionic surfactants;

[0066] 6 parts of anionic surfactant;

[0067] 4 parts of antirust agent;

[0068] 5 parts of organic corrosion inhibitor;

[0069] 3 parts of defoamer;

[0070] 4 parts of builder;

[0071] 1 part of fungicide;

[0072] 50 parts of deionized water;

[0073] Wherein, the weight ratio of the alkylphenol polyoxyethylene ether OP-10 to the lauric acid diethanolamide and the fatty alcohol polyoxyethylene ether AEO-9 in the nonionic surfactant is 1:0.4: 1.3;

[0074] The anionic surfactant is selected from fatty alcohol polyoxyethylene ether sodium sulfate AES;

[0075] Described antirust agent is selected from sodium petroleum sulfonate;

[0076] The organic corrosion inhibitor is selected from benzotriazole;

[0077] The defoamer is selected from polyether defoamer SPG-10, purchase...

Embodiment 2

[0086] Calculated in parts by weight, the preparation method of the special cleaning agent component raw material for the environmental protection water-based motor train unit and the special cleaning agent for the environmental protection water-based motor train unit is the same as in Example 1;

[0087] The difference is that the weight ratio of the alkylphenol polyoxyethylene ether OP-10 to the lauric acid diethanolamide and the fatty alcohol polyoxyethylene ether AEO-9 in the nonionic surfactant is 1:0.1 :1.

Embodiment 3

[0089] Calculated in parts by weight, the preparation method of the special cleaning agent component raw material for the environmental protection water-based motor train unit and the special cleaning agent for the environmental protection water-based motor train unit is the same as in Example 1;

[0090] The difference is that the weight ratio of the alkylphenol polyoxyethylene ether OP-10 to the lauric acid diethanolamide and the fatty alcohol polyoxyethylene ether AEO-9 in the nonionic surfactant is 1:1 :3.

Abstract

The invention provides an environment-friendly water-based cleaning agent special for a motor train unit and a preparation method of the environment-friendly water-based cleaning agent. The cleaning agent comprises the following raw materials: 10-90 parts of a nonionic surfactant; 1 to 20 parts of an anionic surfactant; 1-20 parts of an antirust agent; 0-10 parts of an organic corrosion inhibitor; 1-6 parts of a defoaming agent; 0-7 parts of a builder; 0-5 parts of a bactericide; and deionized water. The cleaning agent provided by the invention has very strong cleaning ability and good rinsing performance, and has very good corrosion resistance to nonferrous metals (such as aluminum, copper and the like).

Description

technical field [0001] The invention relates to the technical field of cleaning agents, in particular to an environment-friendly water-based cleaning agent for EMUs and a preparation method thereof. Background technique [0002] In the process of manufacturing, using and maintaining motor vehicle products and parts, it is often necessary to clean all kinds of dirt attached to the surface of products and parts (such as metal shavings, cutting fluid, abrasives and various greases and dust during processing) And acid, alkali, salt and other electrolytes and hand sweat, friction and wear products and corrosion products, etc.), and achieve a certain surface cleanliness to ensure the smooth progress of the processing process, eliminate the hidden dangers of metal corrosion and friction and wear, and prevent corrosion and wear from continuing Development, to ensure the intrinsic and surface quality of the product, and to prolong the service life. [0003] The water-based liquid me...
