Water-based metal-degreasing cleaning agent

Abstract

The invention discloses a water-based metal-degreasing cleaning agent. The water-based metal-degreasing cleaning agent comprises the components in percent by weight: 10-30% of composite surface active agent, 5-10% of cleaning additive, 2-5% of corrosion inhibiting agent, 0.4-0.8% of hard-water resistant agent, 0.05-0.2% of defoaming agent and the balance of deionized water. By mass, the composite surface active agent is a mixture compounded by LAS (sodium alkyl benzene sulfonate), AEO-9 (Fatty alcohol polyoxyethylene ether) and TX-10 (alkylphenol ethoxylates) according to the mass ratio of 1:2:1; the corrosion inhibiting agent is a mixture compounded by benzotriazole (BTA) and benzimidazole (BIA) according to the mass ratio of 1:1; the cleaning additive is a mixture compounded by 4A zeolite, sodium metasilicate and sodium carbonate according to the mass ratio of 1:1:1; the defoaming agent is a polyether-modified organic silicon defoaming agent. The water-based metal-degreasing cleaning agent disclosed by the invention has the characteristics of low surface tension, fast defoaming, long foam-inhibiting time, low cost and less use amount and the like.

Description

technical field [0001] The invention relates to the field of cleaning agents, in particular to a water-based metal degreasing cleaning agent. Background technique [0002] In heat treatment machining and maintenance and repair of auto parts, petroleum solvents are mostly used to clean the parts, which is easy to clean off the dirt on the metal surface, but it is flammable, harmful to the human body, and seriously polluted, and the metal parts after cleaning are easy to clean. Rust, so it has been replaced by water-based metal degreasing cleaning agent. [0003] High-efficiency low-foam metal cleaning agent is composed of surfactants and cleaning aids based on water. It has excellent permeability, emulsification and ability to remove oil stains. When it is directly used to clean metal parts, it will not produce any spots. Corrosion, oxidation or other harmful reactions, it can be a good substitute for petroleum solvent-based cleaning agent to clean metal parts, and the price...

Problems solved by technology

However, general water-based metal degreasing cleaning agents contain harmful substances such as phosphorus and nitrite, and do not have environmental protection performance. The efficient and environmentally friendly cleaning agents on the market are civil and household cleaning agents, which are not suitable for use in machinery. Cleaning action of metal parts
