Abstract

The invention relates to a phosphorus-free degreasing agent for carbon steel. The agent is a liquid prepared from sodium bicarbonate, alkyl dimethylamino acetic lycine, octyl phenyl polyurethane vinyl ether, sodium gluconate and water through mixing. With the agent, grease on stainless steel surfaces can be removed quickly, and the effect is remarkable. The degreasing agent for stainless steel is prepared from the components as follows: 0.6% of sodium bicarbonate, 3.1% of alkyl dimethylamino acetic lycine, 2.8% of octyl phenyl polyurethane vinyl ether, 0.9% of sodium gluconate and 92.6% of water.

Description

A kind of carbon steel agent of non-phosphate degreasing
Technical field
The present invention relates to Treatment of Metal Surface, and in particular to a kind of carbon steel agent of non-phosphate degreasing, the degreasing agent is used for the oils and fatss of carbon steel surface adhesion carries out defat.
Background technology
Electrochemical deoiling, it is exactly a kind of method that carbon steel surface and oil contaminant is removed using alkaline chemical solution, to reach the effect of surface cleaning, the present invention provides a kind of carbon steel agent of non-phosphate degreasing of environment-friendly type, carbon steel surface and oil contaminant not only can be effectively removed, and to human body avirulence.
A kind of carbon steel agent of non-phosphate degreasing, rate of charge is respectively sodium bicarbonate:0.6%th, alkyl-dimethyl oxyneurine:3.1%th, the poly- ammonia vinyl Ether of octyl phenyl:2.8%th, sodium gluconate:0.9%th, water:92.6%.This carbon steel agent of non-phosphate degreasing, can be such that carbon steel surface more cleans and light, and the later stage for being easy to carbon steel is surface-treated, the effect is significant in terms of carbon steel surface-beautifying.
The content of the invention
It is an object of the invention to provide a kind of with the chemical degreasing agent for improving carbon steel surface cleanness degree, being easy to the later stage to be surface-treated, the mechanism of action is will to stick to the cold-rolling oil of surface of steel plate by saponification.Antirust oil and other residues are removed.
The present invention realizes in the following way purpose:Surfactant has relatively low surface tension, effectively can peel off oils and fatss from carbon steel surface.
Nitrogen-atoms and oxygen atom in chelating agen can form other chelates with the calcium ions and magnesium ions in water, prevent the deposition of calcium and magnesium phosphate, carbonate.
Inorganic builders can be dispersed into little dirt particles and contribute to water softening big dirt particles.
Described surfactant is the poly- ammonia vinyl Ether of octyl phenyl.
Described chelating agen is sodium gluconate.
Described inorganic builders are sodium bicarbonate.
NPE is aqueous degreasing agent.
Specific embodiment
With reference to embodiments the present invention will be further described.
Parts by weight of raw materials is constituted:
Sodium bicarbonate  6g
Alkyl-dimethyl oxyneurine 31g
The poly- ammonia vinyl Ether 28g of octyl phenyl
Sodium gluconate 9g
Water 926ml.
6g sodium bicarbonate, 31g alkyl-dimethyl oxyneurines, the poly- ammonia vinyl Ether of 28g octyl phenyls, 9g sodium gluconates and 926ml water are carried out into premixing.After mix homogeneously, that is, required carbon steel chemistry degreaser is obtained, its density is about 1.05g/cm3
Obtained carbon steel chemistry degreaser is tested, can be seen by different test specimens, the carbon steel surface after oil removing is more cleaned and light.But due to being influenced each other by composite factors such as degreaser temperature, oils and fatss property, times in oil removal process, therefore the cleaning effect of test specimen is also different, should be according to field condition flexible Application, appropriateness grasps various conditions, could obtain ideal cleaning effect.
It should be noted that, above example is only to illustrate technical scheme and unrestricted, although being described in detail to the present invention with reference to above-described embodiment, still technical scheme can be modified or equivalent, without deviating from the spirit and scope of technical solution of the present invention, all should cover in the middle of scope of the presently claimed invention.
