Low-temperature degreasing cleaning agent

Abstract

The invention discloses a low-temperature degreasing cleaning agent, comprising, by mass, 10-30% of chemically pure sodium hydroxide, 2-5% of chemically pure sodium hypochlorite, 5% of a chemically pure surfactant, 0.1% of a chemically pure chelating auxiliary agent, 1-3% of a chemically pure antibacterial agent, and the balance being chemically pure deionized water. The surfactant comprises at least one of an NP series surfactant, fatty acid methyl ester (FMEE), a heterogeneous tridecane alcohol ethoxylated compound and an RF series surfactant; the chelating auxiliary agent comprises ethylenediamine tetraacetic acid (EDTA); and the surfactant comprises an RF-25-1 surfactant; and the antibacterial agent is triclosan. With the above way, the low-temperature degreasing cleaning agent provided by the invention can be used at a low temperature lower than or equal to 60 DEG C, contains low bubble content or no bubble, can be used for cleaning rotating steel belts, can be used for cleaning rotating metal products with a contact time longer than 20 seconds at a low temperature environment, and has antibacterial property as well as environmental protection property.

Description

technical field [0001] The invention relates to the field of cleaning agents, in particular to a low-temperature degreasing cleaning agent. Background technique [0002] In the strip steel surface coating and coating processing production line, the cleaning and degreasing of the strip steel surface is an important link that affects product quality. Practice has proved that if the degreasing of the surface of the strip is not complete, the paint or coating will be difficult to fully spread and adhere to the substrate, and in severe cases, the coating will peel and fall off. Strip cleaning and degreasing is to use the active ingredients in the degreasing agent to reduce the adhesion of surface oil, and through saponification, dispersion, and emulsification, the oil is converted into soap or in an emulsified state, and detached from the steel strip substrate. At the same time, the chelating agent in the degreasing agent interacts with the metal ion components in the oil to for...

Problems solved by technology

[0003] At present, the domestically produced degreasing agents that can be used at low temperatures are all soaking type, and the degreasing time is long, which cannot meet the degreasing requirements of high-speed strip steel, and the degreasing agent applied to strip steel must be used at a higher temperature ( 70 ~ 85°C) to achieve good results, while general cleaning agents need to be heated, which consumes more energy and pollutes the air environment. At the same time, a large number of bubbles generated during use will not only take away part of the degreasing waste of chemicals and worsen the working environment on site
