Efficient cooling metal surface treating agent

Abstract

The invention discloses an efficient cooling metal surface treating agent. The efficient cooling metal surface treating agent is prepared from the following raw materials of, by weight, 7.8-9 parts of emulsified asphalt, 2.1-2.5 parts of molybdenum carbide, 0.7-1 part of ceramic powder, 2.3-3 parts of glycerol, 2.8-3 parts of coolants, 0.4-0 .5 part of manganese naphthenate, 40-50 parts of polyvinyl alcohol, 12-15 parts of polyethylene glycol, 0.4-0.6 part of emulsifiers op10, 0.3-0.5 part of glycerol, 0.6-0.8 part of triethanolamine, 6-8 parts of benzotriazole, 4-6 parts of cinnamic acid benzyl ester, 2-3 parts of sodium dodecyl sulfate, 0.4-0.6 part of butanedial, 4-5 parts of nano-cellulose and an appropriate amount of deionized water. The efficient cooling metal surface treating agent has good cooling and lubricating performance and good usage prospects, is not liable to hydrolysis, and is good in heat resistance, stain resistance and rust resistance.

Description

technical field [0001] The invention relates to the technical field of metal surface treatment agents, in particular to an efficient cooling metal surface treatment agent. Background technique [0002] According to statistics, every year in the world, steel products with a total weight equivalent to 10-20% of the annual metal output cannot be used due to corrosion, rust and other reasons. For this reason, people have adopted various anti-rust methods to avoid rust and reduce loss. There are various kinds of antirust agents, among which sodium nitrite has been favored and widely used because of its excellent antirust performance and low price. A lot of research and development work has been carried out, and a variety of alkyl, alkoxy, halo, naphthoic acids and their derivatives, nitrobenzoic acids, and borates, borates, and molybdates have been prepared. The main material to replace the new water-soluble rust inhibitor of sodium nitrite. Although these new antirust agents ...

Problems solved by technology

[0003] Guo Jun proposed in the article "Development of PVA Water-Soluble Polymer Peelable Antirust Film" that by adding antirust agent and other additives to polyvinyl alcohol, it is placed in a beaker in a constant temperature water bath at a temperature of 99°C. Heating in middle temperature until completely dissolved, and then uniformly coating it on the metal surface by coating casting method, drying to form a film, and measuring the performance of the film. The experimental results show that the surface has good rust resistance. In cold water below 40 ° C, almost It is completely insoluble in water, but when placed in hot water above 40°C, the film will gradually become soft and thin, and finally dissolve completely, so the application area is limited
