Problems solved by technology

[0002] Degreasing, also known as degreasing, is an important process of metal surface treatment. The main method is to remove oil stains on the metal surface by alkali washing. The degreasing agent is a complex mixture of organic and inorganic chemicals in the water base. A new type of industrial degreasing agent developed based on the principle of saponification. The degreasing agent is mainly composed of multiple groups of surface active agents and builders. The decontamination ability is not very good, resulting in the cleaning of the surface of the noise reduction component is not clean enough. In addition, because the existing degreasing agent has a large environmental pollution, it is not conducive to environmental protection

Abstract

The invention provides a surface degreaser of an engine noise elimination assembly and a preparation method of the surface degreaser. The surface degreaser comprises 15-17 parts of sodium dodecyl benzene sulfonate, 17-19 parts of sodium ethoxylated alkyl sulfate, 15-16 parts of nonyl phenol alkylphenol polyoxyethylene, 16-18 parts of cocoanut fatty acid diethanolamide, 14-15 parts of rhamnolipid,14-15 parts of alkyl glycoside, 16-18 parts of zinc vitriol, 18-22 parts of sodium tripolysilicate, 17-20 parts of sodium citrate, 16-18 parts of tributyl citrate, 14-15 parts of benzotriazole, 15-16parts of polydimethylsiloxane and 14-15 parts of polyaspartic acid. By means of a surfactant included in the surface degreaser, the emulsification function is enhanced, the surface tension can be reduced, permeability can be enhanced, the cleaning effect to the noise elimination assembly can be improved, the surface of the noise elimination assembly is not damage during cleaning, and surface smoothness can be enhanced.
