Abstract

The invention provides an environment-friendly degreasing agent and a preparation method thereof. The environment-friendly degreasing agent is prepared by the following steps: (1) sodium metasilicate pentahydrate, sodium lignin sulfonate, sodium carbonate, sodium hydroxide, sodium citrate and distilled water are mixed for stirring by 10-20 minutes by a magnetic stirrer at rotating speed of 300-500 r / min under room temperature; and (2) alginate fibers, carboxymethylcellulose, 4A zeolite, nonyl phenol polyoxyethylene ether, cocamidopropyl dimethylamine oxide, squalane and polyoxyethylene sorbitan monostearate are added for heating to 40-60 DEG C, are stirred by 20-40 minutes at 200-300 r / min, and are cooled. The environment-friendly degreasing agent is excellent in degreasing efect, is higher in degreasing rate at room temperature and high temperature, is relatively higher in degreasing rate at high temperature, and meanwhile, contains no phosphor to achieve greenness and environmental protection.

Description

technical field [0001] The invention relates to the technical field of fine chemicals, in particular to an environment-friendly degreasing agent and a preparation method thereof. Background technique [0002] In the surface treatment process of metal materials, the degreasing process is a very important link. All kinds of oil stains on the surface of metal materials will not only hinder the formation of phosphating film, but also affect the bonding force and corrosion resistance of the coating. According to statistics, the proportion of poor coating and conversion coating caused by incomplete degreasing Generally, it accounts for 60%-80%, so choosing a suitable degreasing agent is very important for the pre-painting treatment process. At present, polyphosphate represented by sodium tripolyphosphate is still the main component of most degreasing agents. This is because polyphosphate can not only soften hard water, but also capture various metal components contained in dirt, ...
