Problems solved by technology

[0003] At present, during the use of degreasing agents, in order to enhance the decontamination effect, a large amount of tackifier or surfactant is often added, which will cause continuous foaming on the steel surface
An appropriate amount of foam can help suspend oil stains, but too much foam or foam that is difficult to remove will emerge from the washing machine, pollute the workshop, and cause the loss and waste of degreasing agent; at the same time, the existence of foam for a long time may also cause deterioration of steel parts and damage Affects the quality of finished steel parts
Especially in winter when the degreasing agent is used at room temperature, the water temperature is low (about 5°C), not only the decontamination effect is significantly reduced, but also the amount of foam is higher, which seriously affects the degreasing efficiency of steel parts

Abstract

The invention provides a high-efficiency degreasing agent. The high-efficiency degreasing agent comprises, by weight, 3-5 parts of emulsifying agent, 2-4 parts of dispersing agent, 10-50 parts of washing assistant, 2-3 parts of complexing agent and 60-80 parts of water. The cleaning ability of the high-efficiency degreasing agent can be known through testing. The prepared high-efficiency degreasing agent has the good cleaning ability on greasy dirt at 25 DEG C and 5 DEG C. A foam capacity test shows that the high-efficiency degreasing agent has low foam capacity at 25 DEG C and 5 DEG C. In addition, the contents of raw material ingredients adopted for the high-efficiency degreasing agent are low and all belong to environment-friendly reagents. The high-efficiency degreasing agent has goodindustrial application prospects.

Description

technical field [0001] The invention belongs to the technical field of metal material surface cleaning agents, and more specifically, the invention relates to a high-efficiency degreasing agent and a production method. Background technique [0002] Steel parts must be degreased before painting to remove pollutants such as grease, scale and rust attached to the surface, which is the key to ensuring the quality of the next phosphating process and coating quality. [0003] At present, during the use of degreasing agents, in order to enhance the decontamination effect, a large amount of tackifiers or surfactants are often added, which will cause continuous foaming on the steel surface. An appropriate amount of foam can help suspend oil stains, but too much foam or foam that is difficult to remove will emerge from the washing machine, pollute the workshop, and cause the loss and waste of degreasing agent; at the same time, the existence of foam for a long time may also cause dete...
