Problems solved by technology

[0005] Chinese patent CN1548582A discloses a special cleaning agent for cold-rolled steel plates, the main components of which are non-ionic surfactants, alkaline compounds, chelating agents, solubilizers and solvents; Solubilizers such as acid salts can avoid stratification, and the cleaning effect is poor under high-pressure spray conditions, and there are a lot of foam at medium and low temperatures (10 degrees Celsius to 60 degrees Celsius)
Chinese patent CN103937628A discloses a high-alkaline foam-free spray cleaning agent, whose main components are strong alkali, polyether, surfactant, solubilizer and solvent; During the cleaning process, a relatively satisfactory cleaning effect has been achieved, but there is still the problem of excessive foaming at medium and low temperatures, which limits its use

Abstract

Disclosed are a stainless steel high-pressure spray cleaning agent and a preparation method thereof. The stainless steel high-pressure spray cleaning agent comprises the following components of, by mass, 3-10 parts of N-lauryl imino dipropionate sodium salt, 0.05-0.2 part of calcium nitrate, 3-10 parts of isomeric alcohol polyoxyethylene polyoxypropylene phenyl capping polyether, 10-30 parts of saponification agent, 1-5 parts of chelating agent and 60-80 parts of water. The stainless steel high-pressure spray cleaning agent adopts all the components of the mass parts, the cleaning effect is good, cosolvent and defoamer do not need to be added additionally, the stainless steel high-pressure spray cleaning agent can be used at both high and low temperatures, namely the stainless steel high-pressure spray cleaning agent can be used at the temperature of 10-80 DEG C, and delamination is not liable to occur to the stainless steel high-pressure spray cleaning agent during storage and use.

Description

technical field [0001] The invention relates to the technical field of oil stain cleaning, in particular to a stainless steel high-pressure spray cleaning agent and a preparation method thereof. Background technique [0002] Stainless steel is more and more popular because of its excellent performance. During the production and processing of stainless steel, the surface is often stained with cutting oil, drawing oil and other oil stains that need to be cleaned. For workpieces with thick oil stains on the surface or stubborn oil stains on the surface after a long period of storage, strong alkaline water-based cleaning agents are generally used on the market to clean the stainless steel surface with high-pressure spray. Strong alkaline water-based cleaning agents have good cleaning effect and fast cleaning speed, and stainless steel itself is corrosion-resistant, so strong alkaline water-based cleaning agents usually do not cause any adverse effects on stainless steel surface...
