Oil and rust removing agent for surface of copper material and preparation method of oil and rust removing agent

Abstract

The invention discloses an oil and rust removing agent for the surface of a copper material and a preparation method of the oil and rust removing agent. The oil and rust removing agent is prepared from, by weight, 8-11 parts of polyving akohol, 10-13 parts of polyacrylamide, 11-14 parts of sebacic acid, 2-6 parts of alkylphenol ethoxylates, 8-11 parts of konjac glucomannan, 3-7 parts of benzotriazole, 3-6 parts of dimethyl methylphosphate, 3-6 parts of vinyltriethoxysilane, 3-7 parts of boric acid, 11-14 parts of sodium alga acid, 3-6 parts of tannic acid, and 2-5 parts of N-hydroxymethyl-3-(dimethoxyphosphoryl) propanamide. The oil and rust removing agent for the surface of the copper material is reasonable in formula, good in rust removing effect, high in rust removing efficiency and capable of removing oil dirt and rust spots on the metal surface rapidly, and corrosion to the copper material is avoided; and in addition, components in anti-rust liquid are environmentally friendly and non-poisonous, and the preparation method is simple and low in cost.

Description

technical field [0001] The invention relates to a copper material surface degreasing and derusting agent and a preparation method thereof. Background technique [0002] In the production of non-ferrous metals, the output of copper ranks second only to aluminum. Due to its excellent strength, machinability, electrical conductivity, weldability and corrosion resistance, it has been widely used in various fields such as industry, military and civilian for a long time. According to the data, at present, the marine industry alone consumes more than 10 tons of copper and its alloys every year. With the development of the electric power industry and the large-scale construction of thermal power generation, copper alloys are more and more widely used in various fields. Under normal circumstances, copper has no tendency to corrode. In the electrochemical order, copper has a higher positive potential than hydrogen, so copper has high thermodynamic stability and will not depolarize hy...

Problems solved by technology

However, most of the degreasing and derusting agents on the market now use strong alkaline hot solutions (high energy consumption, heavy pollution, and the oil slick on the surface of the working fluid will cause secondary oil pollution to the treated parts), or use strong acids, or use Flammable, explosive, and toxic organic solvents produce toxic, highly corrosive, and heavy pollution of gas, liquid, and solid wastes
