Problems solved by technology

Generally, when the temperature rises, the cleaning ability of the cleaning agent is enhanced, because when the temperature rises, the dissolution rate of the wax will be accelerated, but high temperature will cause waste of resources and increase operating costs
[0004] In addition, although various wax removers currently on the market can clean the polishing wax and grease on the metal surface to a certain extent, due to the defects in their components, content and process, the rust resistance is very poor, and the metal products after cleaning The parts are easy to rust, and the product has a lot of foam, which is dangerous to use and poor cleaning efficiency

Embodiment 1

[0036] According to the formula in Table 1, the removal ability of alcohol amine type oleic acid soaps with different compositions to the polishing wax on the steel sheet surface was tested.

[0037] Table 1 The wax removal ability of alcohol amine type oleic acid soap

[0038]

[0039] As can be seen from Table 1, the compound whose molar ratio of oleic acid and diethanolamine is 1:2 has the best wax removal performance, so the diethanolamine oleic acid soap formed by this molar ratio is selected for use in the following examples.

Embodiment 2

[0041] A water-based metal anti-rust degreasing wax removal cleaning agent, which consists of the following formula by weight:

[0042] Polyacrylic acid or its copolymers, crotonic acid or its copolymers, acrylic acid maleic anhydride copolymer 18%,

[0043] Diethanolamine Oleic Soap 16%,

[0044] Alkanolamide Phosphate 6503 14%,

[0045] Dienyl succinimide T154 8%,

[0046] Sodium Tripolyphosphate 6%,

[0047] Anhydrous sodium metasilicate 2%,

[0048] Penetrant TA-2 7%,

[0049] Zinc Dialkyl Dithiophosphate 2%,

[0050] Macrogol 400 15%,

[0051] The balance is deionized water.

Embodiment 3

[0053] A water-based metal anti-rust degreasing wax removal cleaning agent, which consists of the following formula by weight:

[0054] Anionic carboxylic acid type macromolecule surfactant (identical to the components of Example 2) 16%,

[0055] Diethanolamine Oleic Soap 16%,

[0056] Alkanolamide Phosphate 6503 18%,

[0057] The addition of other components is identical with embodiment 2,

[0058] The balance is deionized water.

Abstract

The invention provides a water-based rust-proofing, degreasing and wax removing cleaning agent and a preparation method and application thereof. The cleaning agent comprises a high molecular surfactant, diethanol amine oleic soap, alkylolamide phosphate 6503, diallyl succinimide T154, sodium tripolyphosphate, sodium metasilicate, a penetrant TA-2, zinc dialkyl dithiophosphate, polyethylene glycol 400 and deionized water. The cleaning agent is applicable to manufacturing of various metals; dirt such as polishing wax, grinding wax, grease and greasy dirt on the metal surface can be cleaned under normal temperature, instead of being cleaned under high temperature; the cleaning agent is low in use concentration, high in permeability, low in foam, high in wax removing efficiency, free from strong acid and sodium hydroxide, free from damage to a matrix, high in physicochemical stability, long in service life, free from APEO (alkylphenol ethoxylates) nonionic surfactant, green, nontoxic, and high in rust-proofing performance.

Description

technical field [0001] The invention relates to the field of metal surface treatment, in particular to a cleaning agent for anti-rust, degreasing and wax removal of metal, a preparation method and application thereof. Background technique [0002] After the metal workpiece is polished with polishing wax, the wax scale remains on the workpiece by mechanical adsorption, intermolecular adsorption and electrostatic adsorption. The main components of polishing wax are mineral oil, animal and vegetable oil, paraffin, natural wax, resin, stearic acid and abrasives. At present, the methods of wax removal, degreasing and degreasing of metal mainly include the following categories: organic solvent method, chemical method, electrochemical method and water-based cleaning agent method. Commonly used organic solvents cannot completely remove polishing wax, especially the polishing materials such as metal oxides and carbides on it cannot be effectively cleaned; and chlorine-containing sol...
