Neutral oil and rust removing detergent

Abstract

The invention discloses neutral oil and rust removing detergent. The neutral oil and rust removing detergent comprises the following raw materials in parts: 10-15 parts of acrylic acid, 15-18 parts of methyl methacrylate, 10-15 parts of styrene, 12-15 parts of ethylene oxide, 5-10 parts of amino trimethylene phosphonic acid, 3-5 parts of etidronic acid, 3-8 parts of ferric hydroxide, 5-10 parts of sodium benzoate, 5-8 parts of triethanolamine, 10-15 parts of sodium bicarbonate, 12-15 parts of potassium carbonate, 15-20 parts of sodium alkyl benzene sulfonate, 8-12 parts of fatty alcohol-polyoxyethylene ether, 10-15 parts of trisodium phosphate, 12-20 parts of urea, 10-15 parts of citric acid, and 100-150 parts of purified water. The neutral oil and rust removing detergent is neutral, has little corrosion to equipment made of various materials, widens the application range, and has better storage stability.

Description

technical field [0001] The invention relates to the technical field of cleaning agents, in particular to a neutral cleaning agent for degreasing and derusting. Background technique [0002] At present, metal processing, machinery manufacturing and other industries need to use degreasing and rust removing agents to treat the processed metal surface before spraying, electroplating, plastic spraying and other processes; some pipes, wires, plates or devices also need Carry out degreasing and rust removal. Existing various effective oil and rust removal technologies and products have been widely used in industry. For example, most of the existing degreasing and rust removing agents are composed of inorganic acids, organic acids, salts, corrosion inhibitors, surfactants and water, or are composed of sulfuric acid and various anion and cationic surfactants. What these products have in common is that they are all derusted in a strongly acidic atmosphere, and the degreasing and der...

Problems solved by technology

This has just caused this kind of oil and rust remover to have some defects.

Applicable materials are limited to ferrous metals. It is not suitable for more precise small light rust components and galvanized sheets currently used in large quantities. The processing time must be strictly controlled. Excessive corrosion will occur if the time is too long. The corrosion inhibitor should be used in the acid solution Unstable, easy to decompose and fail, not conducive to long-term storage of products
