Environmentally-friendly metal rust inhibitor

Abstract

The invention discloses an environmentally-friendly metal rust inhibitor, which comprises, by weight, 5-7 parts of zinc sulfate, 3-5 parts of an amide-based gas-phase rust inhibitor, 4-6 parts of sodium propionate, 2-4 parts of a complexing agent, 1-3 parts of a surfactant, 3-5 parts of kaolin, 7-9 parts of fatty alcohol polyoxyethylene ether, 6-8 parts of diethanolamine, 5-7 parts of modified silicon resin, 4-6 parts of octadecylamine N-oleoyl sarcosinate, 1-3 parts of octadecylamine, 4-6 parts of sodium alkylsulfonate, and 100-300 parts of deionized water. According to the present invention,the environmentally-friendly metal rust inhibitor has characteristics of scientific and reasonable formula, strong anti-rust property, strong degreasing and decontaminating ability, no adverse effecton non-ferrous metals, no foam generation, no overflow phenomenon under high pressure, excellent contact rust prevention performance and good gas-phase rust resistance.

Description

technical field [0001] The invention relates to the field of chemical products, in particular to an environment-friendly 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. Metal is widely used in various industries such as machinery, automobiles, home appliances, construction, etc. In...

Problems solved by technology

The existing anti-rust agents are composed of base oil and oil-soluble corrosion inhibitors, which can only play the role of contact anti-rust, and cannot form effective anti-rust protection for those parts that cannot be exposed to anti-rust agents.
