Abstract

The invention provides a metal surface degreasing agent, which aims to solve the problems that the conventional degreasing agent cannot completely remove fouling on the metal surface, and has higher corrosion on materials; and the treated metal surface has adverse influence on subsequent phosphorization and passivation processes. The degreasing agent comprises the following components in percentage by weight: 5 to 25 percent of common alkali, 10 to 15 percent of buffering agent and auxiliary agent, 3 to 5 percent of surfactant, 0.5 to 1 percent of defoaming agent and foam inhibitor, and the balance of water, wherein the common alkali is one or more of sodium hydroxide or potassium hydroxide; the buffering agent and the auxiliary agent are one or more of sodium silicate, sodium tripolyphosphate and potassium permanganate; the surfactant is one or more of BJJ001, BJJ003 and AEC; the defoaming agent and the foam inhibitor are one or more of organic silicon and organic phosphate. The metal surface degreasing agent has the characteristics of high efficiency, safety, environmental protection, low foam and no corrosion on steel plates, zinc, aluminum, copper, plastic or rubber.

Description

technical field

[0001] The invention relates to a degreasing agent for metal surface treatment. Background technique

[0002] Degreasing plays an important role in metal surface treatment. Traditional degreasing agents are difficult to completely remove dirt on the surface, and are highly corrosive to materials; the treated metal surface will have adverse effects on the subsequent phosphating and passivation processes; Defects such as defoaming. Contents of the invention

[0003] In order to overcome the deficiencies in the prior art, the object of the present invention is to provide a metal surface degreasing agent with high efficiency, safety, environmental protection, low foam and small amount, which is suitable for surface degreasing and cleaning of steel plates, zinc, aluminum, copper, plastics, rubber and other materials .

[0004] The formula of the present invention is composed of: 15%-25% (percentage by weight, the same below) of commonly used alkali, which is ...
