Description

technical field [0001] The invention relates to the field of metal surface anticorrosion treatment, 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 my 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, e...
