A kind of ultra-high pressure spray cleaning agent and its preparation method and application

Abstract

The invention provides an ultrahigh pressure spray cleaning agent and a preparation method and application thereof. The ultrahigh pressure spray cleaning agent comprises 100% branched fatty alcohol-polyoxyethylene ether, non-sealing end ethyleneoxide-propyleneoxide segmented copolymer and benzyl quaternary ammonium salt. A 100% branched fatty alcohol-polyoxyethylene ether non-ionic surface active agent, the non-sealing end ethyleneoxide-propyleneoxide segmented copolymer and a benzyl quaternary ammonium salt cationic surface active agent of the ultrahigh pressure spray cleaning agent have a synergistic effect, and thus the ultrahigh pressure spray cleaning agent has ultrahigh wetting cleaning capacity and can still maintain low foam after being polluted by emulgator cutting fluid; and besides, the alkalinity of the ultrahigh pressure spray cleaning agent is low, corrosion of a strong-alkali cleaning agent to aluminum, cooper and rubber parts of cleaning equipment is greatly reduced, and the ultrahigh pressure spray cleaning agent can be widely applied to the field of spray cleaning.

Description

Technical field [0001] The invention belongs to the technical field of cleaning agents, and relates to a spray cleaning agent and a preparation method and application thereof, in particular to an ultra-high pressure spray cleaning agent and a preparation method and application thereof. Background technique [0002] With the development of the metal processing industry, the requirements for ultra-high pressure spray cleaning agents have gradually increased. Although the solvent-based cleaners commonly used in the past have strong cleaning power and low foam, the solvent-based cleaners have low flash point and volatility, which bring safety hazards to production and have certain hazards to human health. At the same time, the cost of solvent-based cleaners It is also higher than water-based products. [0003] The above shortcomings make the application of water-based cleaning agents in the ultra-high pressure spray deburring process more and more. However, the biggest disadvantage o...

Problems solved by technology

The formulation includes 0 to 4 ethylene oxide or propylene oxide nonionic surfactants and benzyl quaternary ammonium salts, but it does not disclose branched EO alcohols, nor does it disclose uncapped ethylene oxide / propylene oxide copolymer, and there is no disclosure of synergy between branched EO alcohols, uncapped EO / PO copolymers, and benzyl quaternary ammonium salts

[0014] The traditional water-based ultra-high-pressure spray cleaning agent also has the following disadvantages: no or a small amount of low-foaming non-ionic surfactant is added, this type of cleaning agent has limited decontamination ability, poor wetting performance, and is prone to Dirt remains on the metal surface because it is not wetted by the cleaning agent; once the low-foaming non-ionic surfactant used is emulsified by the emulsified cutting fluid, it cannot control the foam generated after the emulsified cutting fluid is mixed with the cleaning agent; Strong alkali is used to ensure high cleaning power under low foam conditions, but strong alkali will cause corrosion to aluminum, copper and cleaning equipment
