Normal-temperature nonphosphorus degreasing agent for metal surface processing and preparation method thereof

Abstract

The invention discloses a normal-temperature nonphosphorus degreasing agent for metal surface processing and a preparation method thereof. The normal-temperature nonphosphorus degreasing agent comprises the raw material percentages by weight: 10-20% of sodium hydroxide, 5-10% of sodium metasilicate, 3-5% of sodium carbonate, 6-8% of alkylphenol polyoxyethylene, 2-4% of linear alkyl benzene sulphonate, 1-2% of 2-butoxyethanol, 0.5-1% of polyether and the balance of water. Compared with the prior art, the normal-temperature nonphosphorus degreasing agent has the characteristics of normal temperature, environmental protection (non phosphorus), high efficiency, safety, low foam, solubilization, good decontaminability and the like, and does not corrode steel plates, aluminum, copper, plastics, rubber and the like.

Description

technical field

[0001] The invention relates to a normal temperature phosphorus-free degreasing agent for metal surface treatment. Background technique

[0002] In the process of metal surface treatment, degreasing plays a very important role. The common problems of traditional degreasing agents are that the foam is too high, the dispersion performance is poor, oil stains are easy to contaminate the metal surface, and the degreasing and degreasing speed is slow, low temperature conditions The degreasing effect is even worse. Contents of the invention

[0003] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a normal temperature, environmental protection (no phosphorus), high efficiency, safety, low foam, solubilization, good decontamination, suitable for steel plate, aluminum, copper and plastic, rubber A surface degreasing agent for materials such as and a preparation method thereof.

[0004] In order to achi...
