Abstract

The invention provides a metal antirust agent. The metal antirust agent comprises, by weight, 6-10 parts of citric acid, 1-5 parts of edetic acid, 4-8 parts of binary acid, 10-20 parts of monoethaneamine benzoate, 10-20 parts of triethanolamine, 10-20 parts of diethanol amine, 20-30 parts of synthetic boric acid ester, 25-35 parts of macrogol ester, 35-45 parts of epoxy acrylate resin, 30-40 parts of N-octadecane oeoyl sarcosine acid, 0.4-1.0 part of a silicon antifoaming agent and 600-800 parts of water. The metal antirust agent is scientific and reasonable in formula and free of hazardous substances such as trichloroethane and tetrachloroethane and environment pollution, and the ozone sphere at a high altitude cannot be damaged. The degreasing and decontamination capacity is high, and no harmful effect to non-ferrous metal exists. The antirust capability is high, foam is not produced, and the overflowing phenomenon cannot occur at a high pressure.

Description

technical field [0001] The invention relates to the field of chemical products, in particular to a metal antirust agent. Background technique [0002] Metal corrosion is a problem often encountered in production and life. Metal rust not only damages the shape, color and mechanical properties of the metal workpiece itself, but also reduces the quality of its products. In our country, the steel due to metal corrosion accounts for 20% of the total steel output every year, and about 30% of the equipment is scrapped due to corrosion, which not only pollutes the environment, but also wastes a lot of resources and energy consumption. The metal scrapped due to corrosion accounts for about 20%-40% of the world's annual metal output every year, and the corrosion of steel accounts for half of the metal corrosion, which is a serious waste of resources. [0003] Metal is widely used in various industries such as machinery, automobiles, home appliances, construction, etc. In order to imp...
