compared with the traditional phosphorus-containing degreasing agent, the degreasing agent does not contain phosphorus, does not cause environmental phosphorus pollution, and has relatively good environmental protection property. Through adopting isooctanol polyoxyethylene ether, fatty acid methyl ester ethoxylate sulphonate and sodium disilicate as the essential element, combine lauryl alcohol polyoxyethylene ether simultaneously, isomeric alcohol polyoxyethylene ether, propylene glycol methyl ether, triethanolamine and sodium citrate, make above-mentioned degreasing agent have better cleaning performance, cleaning efficiency is better, and when sodium disilicate and isooctanol polyoxyethylene ether, fatty acid methyl ester ethoxylate sulphonate etc. combine to use, make above-mentioned degreasing agent can compromise the characteristic of permeability and emulsibility under normal atmospheric temperature, cleaning performance is better, can have better degrease deoiling effect under the normal atmospheric temperature.
particularly, isooctanol polyoxyethylene ether has better permeability and wettability, better emulsification, dispersion and cleaning performances, better permeability to grease and better grease removal, fatty acid methyl ester ethoxylate sulfonate has better dispersion performance, so that the degreasing agent has low foam, better low-temperature performance and excellent degreasing and dewaxing capabilities, and when 1 to 3 parts of isooctanol polyoxyethylene ether and 4 to 8 parts of fatty acid methyl ester ethoxylate sulfonate are used together, the degreasing synergistic effect is better. On the one hand, the sodium disilicate has better washing assisting capacity and can improve the oil stain removing capacity and removing efficiency of the degreasing agent, and on the other hand, the sodium disilicate has better combination exchange capacity for calcium ions and magnesium ions and has better water softening effect, so that the degreasing agent can adapt to lower washing temperature and can maintain better oil stain removing capacity at normal temperature. Preferably, the sodium disilicate is modified sodium disilicate. Particularly, the traditional degreasing agent usually has certain requirements on degreasing temperature in the degreasing treatment process, and when 5-8 parts of sodium disilicate, 1-3 parts of isooctanol polyoxyethylene ether, 4-8 parts of fatty acid methyl ester ethoxylate sulfonate and the like are jointly used, the degreasing agent can have the characteristics of permeability and emulsibility at normal temperature, has a good cleaning effect, and can have a good degreasing and degreasing effect at normal temperature.

With the rapid development of the industrial society, more and more terminal customers put higher demands on products. In the modern coating industry, customers also place higher demands on industrial cleaning chemicals. In the modern coating industry, customers also place higher demands on industrial cleaning chemicals. In industrial cleaning, the traditional degreasing agent contains phosphorus and is not environment-friendly, the cleaning efficiency and the cleaning force are weak, the production efficiency is seriously reduced, and the resource waste is caused. For example, in aluminum profile coating, in order to form a good passivation film on the surface of an aluminum profile in a passivation process, a thorough cleaning process needs to be performed on the surface of the aluminum profile in a degreasing process to expose a clean surface of an aluminum profile workpiece, but the conventional degreasing agent has weak cleaning efficiency and cleaning power, so that the time consumed in the degreasing process is long, and the coating efficiency is seriously affected. Therefore, a high-performance degreasing agent which can simultaneously achieve permeability and emulsibility at normal temperature and a preparation method thereof are lacked. Compared with the traditional phosphorus-containing degreasing agent, the degreasing agent provided by the application does not contain phosphorus in the components, does not cause environmental phosphorus pollution, and is relatively good in environmental protection. Through adopting isooctanol polyoxyethylene ether, fatty acid methyl ester ethoxylate sulphonate and sodium disilicate as the essential element, combine lauryl alcohol polyoxyethylene ether simultaneously, isomeric alcohol polyoxyethylene ether, propylene glycol methyl ether, triethanolamine and sodium citrate, make above-mentioned degreasing agent have better cleaning performance, cleaning efficiency is better, and when sodium disilicate and isooctanol polyoxyethylene ether, fatty acid methyl ester ethoxylate sulphonate etc. combine to use, make above-mentioned degreasing agent can compromise the characteristic of permeability and emulsibility under normal atmospheric temperature, cleaning performance is better, can have better degrease deoiling effect under the normal atmospheric temperature.
