Non-ferrous metal cleaning agent and method of cleaning non-ferrous metal part

Abstract

The invention discloses a non-ferrous metal cleaning agent and a method of cleaning a non-ferrous metal part and relates to the technical field of chemical cleaning agents. The non-ferrous metal cleaning agent is prepared from the following components in percent by weight: 1-10% of an inorganic alkaline substance, 1-5% of sodium polyacrylate, 5-10% of AEO-9, 1-5% of AEO-3, 5-10% of alkyl glycoside, 1-5% of a copper protecting agent, 1-5% of an aluminum protecting agent and water. By means of a synergistic effect of the AEO-9, AEO-3, APG and inorganic alkaline substance, the cleaning agent canpermeate into the inner surfaces of oil stains quickly and make the oil stains be emulsified quickly and separated from the surface of the part, so that the cleaning agent h as an efficient cleaning effect. By adding the copper and aluminum protecting agents, the cleaning agent does not damage the surface of the part, such as color change and corrosion. In addition, the components of the cleaningagent are biodegradable raw materials, so that the cleaning agent does not lead to environmental pollution.

Description

technical field [0001] The invention relates to the technical field of chemical cleaning agents, in particular to a nonferrous metal cleaning agent and a method for cleaning nonferrous metal parts. Background technique [0002] Generally speaking, after the non-ferrous metal parts are processed, there will be fingerprints, dust, processing oil, cutting fluid, grease and other organic and inorganic solid particles attached to the surface of the parts, which will corrode and wear the parts, so after the parts are processed, it is necessary to High-efficiency cleaning agents remove these impurities, among which copper and copper alloys, aluminum and aluminum alloy metal parts are the most common. [0003] High-efficiency cleaners include solvent-based cleaners and water-based cleaners. Among them, solvent-based cleaning agents include gasoline, kerosene, tetrachloroethylene, trichloroethylene, methylene chloride, freon, hydrocarbon solvents, etc. These solvent-based cleaning a...

Problems solved by technology

Among them, solvent-based cleaning agents include gasoline, kerosene, tetrachloroethylene, trichloroethylene, methylene chloride, freon, hydrocarbon solvents, etc. These solvent-based cleaning agents are more or less flammable, explosive, and highly toxic. , destruction of atmospheric ozone, solvent recycling and other issues, and the recycling cost is high; because strong alkali is easy to cause parts to lose gloss, discoloration or even corrosion, the water-based cleaning agent used for non-ferrous metal parts is neutral or very weak alkaline Cleaning agents are the main ones, but these two types of cleaning agents have the defect of poor degreasing effect, although some cleaning agents are degraded due to the addition of surface active ingredients containing nonylphenols (NP) or octylphenols (OP). A good degreasing effect has been obtained, but NP and OP surfactants are difficult to biodegrade, and long-term large-scale use will cause unpredictable damage to the environment
