Highly effective cleaners include solvent-based cleaners and water-based cleaners. The solvent type cleaning agent comprises gasoline, kerosene, tetrachloroethylene, trichloroethylene, dichloromethane, freon, hydrocarbon solvents and the like, and the solvent type cleaning agent has the problems of flammability, explosiveness, high toxicity, damage to atmospheric ozone, solvent recovery treatment and the like, and has higher recovery cost; the water-based cleaning agent for non-ferrous metal parts is mainly neutral or weak alkaline cleaning agent, but both cleaning agents have the defect of poor oil stain removal effect, and although part of the cleaning agents obtain good oil stain removal effect due to the addition of surface active ingredients containing Nonylphenol (NP) or Octylphenol (OP), the NP and OP surfactants are difficult to biodegrade, and the environment is damaged difficultly after long-term large-scale use.
In view of the above, the invention provides a non-ferrous metal cleaning agent which is a water-based cleaning agent and has the advantages of environmental protection and high efficiency.
Specifically, the non-ferrous metal cleaning agent provided by the embodiment of the invention comprises the following components in percentage by weight: 1-10% of 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 copper protective agent, 1-5% of aluminum protective agent and water.
The inorganic alkaline substance can provide an alkaline environment for the cleaning agent, and in the alkaline environment, the cleaning agent can more easily permeate into oil stains, so that the cleaning effect is stronger. In this embodiment, the inorganic alkaline substance may include one or more of potassium hydroxide, sodium metasilicate pentahydrate, and sodium silicate, and sodium metasilicate pentahydrate is preferred.
Fatty alcohol polyoxyethylene ether (AEO), also known as polyoxyethylene fatty alcohol ether, is a biodegradable nonionic surfactant and has emulsifying, foaming and decontaminating functions. AEO-9 and AEO-3 are two fatty alcohol-polyoxyethylene ethers with different HLB (hydrophilic-lipophilic balance), wherein the HLB of AEO-3 is 8.50, and the AEO-3 has good emulsifying effect on greasy dirt with high viscosity; AEO-9 has HLB value of 12.50, and has good emulsifying effect on oil stain with low viscosity. When the cleaning agent is sprayed to the greasy dirt on the surface of the part, the AEO-3 plays a wetting role, so that the greasy dirt with large viscosity is partially emulsified, and meanwhile, the AEO-9 quickly permeates into the greasy dirt to further emulsify the greasy dirt with reduced viscosity, so that the greasy dirt is stripped from the surface of the part, and a cleaning effect is achieved.
The alkyl glycoside (APG) has the characteristics of common nonionic and anionic surfactants, is easily soluble in organic solvents, shows excellent compatibility, stability and surface activity in alkaline solutions, is a novel nonionic surfactant with comprehensive performance, has a dissolving assisting effect when being compounded with fatty alcohol-polyoxyethylene ether, can clarify a cleaning agent, and can enhance the cleaning capacity of the cleaning agent. Most importantly, APG is completely biodegradable in nature without the formation of metabolites that are difficult to biodegrade.
