At present, silicone grease cleaning agents are mainly divided into water-based cleaning agents and solvent-based cleaning agents, but the water-based cleaning agents have the problems of high alkalinity, poor cleaning effect, easy corrosion to nonferrous metals such as aluminum, copper and the like in the cleaning process, and the solvent-based cleaning agents mainly use hydrocarbon solvents and chlorohydrocarbons and have the problems of large smell, flammability, explosiveness and the like in the cleaning process. Therefore, the water-based cleaning agent is still the first choice for cleaning the silicone grease from the aspects of safety, environmental protection and users.
At present, water-based cleaning agents are mostly adopted for cleaning silicone grease, the modes are ultrasonic cleaning and spray cleaning, but the cleaning processes of the two are required to be increased to 60-80 ℃, the energy consumption is high, the cleaning process consumes long time, the concentration of working solution is up to 20-30%, the cleaning efficiency is low, and deep grooves and depressions cannot be cleaned thoroughly.

the water-based silicone grease cleaning agent for the multi-metal comprises the following raw materials in percentage by mass: 6-12% of surfactant, 2-5% of penetrating agent, 2-4% of corrosion inhibitor, 2-8% of emulsifier, 5-10% of inorganic salt, 3-5% of organic amine, 2-5% of solubilizer and the balance of deionized water.
Preferably, wherein: 9% of surfactant, 2% of penetrating agent, 2% of corrosion inhibitor, 3% of emulsifier, 6% of inorganic salt, 3% of organic amine, 2% of solubilizer and the balance of deionized water.
Preferably, wherein: 11% of surfactant, 1% of penetrating agent, 3% of corrosion inhibitor, 2% of emulsifier, 6% of inorganic salt, 2% of organic amine, 2% of solubilizer and the balance of deionized water.
Preferably, the surfactant comprises one or a mixture of more than two of alkylphenol ethoxylates, ethoxylated isomeric tridecanol, fatty alcohol polyoxyethylene ether, isomeric C13 fatty alcohol ether and ethoxylated alcohol.
Preferably, the penetrant comprises one or a mixture of more than two of modified polycarboxylate, polyoxyethylene compound and penetrant AEP.
Preferably, the corrosion inhibitor comprises one or a mixture of more than two of phosphate, thiourea, sodium nitrite, benzotriazole and urotropine.
Preferably, the emulsifier comprises one or a mixture of more than two of polyoxyethylene octyl phenol ether, sodium stearate, polyoxyethylene sorbitan monooleate and polyoxyethylene sorbitan stearate.
Preferably, the inorganic salt comprises one or a mixture of more than two of sodium bicarbonate, sodium tripolyphosphate, ethylene diamine tetraacetic acid tetrasodium salt, sodium metasilicate pentahydrate, sodium pyrophosphate and sodium borate.
Preferably, the organic amine comprises one or a mixture of more than two of monoethanolamine, diethanolamine and triethanolamine.
Preferably, the solubilizer comprises one or a mixture of more than two of phenyl polyethylene oxide phosphate and polyoxyethylene fatty acid ester.
The method for preparing the water-based silicone grease cleaning agent for the multiple metals comprises the following steps:
step S1: adding water into a first reaction kettle, adding inorganic salt, organic amine, a corrosion inhibitor and a rapid penetrating agent, continuously stirring until the inorganic salt, the organic amine, the corrosion inhibitor and the rapid penetrating agent are completely dissolved, and uniformly mixing without precipitation;
step S2: adding the surfactant and the emulsifier into a second reaction kettle, and continuously stirring for 15-30min until the mixture is uniformly mixed;
step S3: and adding the mixed solution in the second reaction kettle into the first reaction kettle, uniformly stirring for 10-20min, adding the solubilizer, and continuously stirring until the solution is transparent, thus obtaining the low-alkalinity water-based silicone grease cleaning agent.
The invention has the beneficial effects that:
the invention provides a general water-based silicone grease cleaning agent for multiple metals, which has a good cleaning effect on silicone grease with high viscosity, is low in alkalinity, free of corrosion to various metals such as aluminum, copper and iron, safe, environment-friendly and low in smell, and is suitable for cleaning silicone grease on the surfaces of multiple metals.
Wherein, the surface active agent adopts the nonionic surface active agent with strong decontamination capability and good stripping effect, and the surface tension can be greatly reduced through the synergistic action of a plurality of surface activities. In addition, the penetrant with strong permeability is selected, so that the permeability of the surfactant in the silicone grease with larger viscosity can be improved, and the stripping speed of the silicone grease can be accelerated under the ultrasonic action of ultrasonic waves. In order to reduce the corrosion to nonferrous metals such as copper, aluminum and the like, organic amine and low-alkalinity inorganic salt are compounded, and a corrosion inhibitor is added, so that the corrosion to the nonferrous metals can be effectively avoided. The emulsifier is non-ionic ether or ester compound with strong emulsifying power to the silicone grease, and the stripped silicone grease is emulsified, so that the silicone grease and oil stain dispersed in the solution are prevented from being adhered to the surface of the metal again to form secondary pollution. The solubilizer selects the ester compound with HLB value of 12-14 and good solubilization effect, can increase the solubility of the surfactant and the emulsifier, improve the stability of the cleaning agent, and avoid layering or precipitation. The water-based silicone grease cleaning agent provided by the invention does not contain an organic solvent, does not contain strong base, has small smell, is non-combustible and non-explosive, is safer and more environment-friendly, and has a good cleaning effect on silicone grease at normal temperature and low concentration mainly through the mutual matching and cooperation of components such as a surfactant, a penetrating agent, an emulsifier and the like and the ultrasonic action of ultrasonic waves.
