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.

Abstract

The invention discloses a metal rust inhibitor, which comprises, by weight, 4-5 parts of sodium citrate, 6-8 parts of ethylenediaminetetraacetic acid, 15-25 parts of an epoxy acrylate resin, 2-3 partsof a silicone defoamer, 2-4 parts of urotropine, 1-3 parts of oily wax, 2-5 parts of vaseline, 1-3 parts of sodium molybdate, 3-6 parts of diethylene glycol propyl ether, 6-8 parts of an epoxy acrylate resin, 6-8 parts of a balance agent, 6-8 parts of a thickener, and 150-200 parts of water. According to the present invention, the metal rust inhibitor has characteristics of scientific and reasonable formula, strong anti-rust property, strong degreasing and decontaminating ability, no adverse effect on 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 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. Metal is widely used in various industries such as machinery, automobiles, home appliances, construction, etc. In order to improve the ...
