Anti-rust agent for steel and iron plates

Abstract

The invention discloses an anti-rust agent for steel and iron plates. The anti-rust agent comprises the following components in parts by weight: 15-25 parts of sodium benzoate, 10-14 parts of sodium nitrite, 8-12 parts of sodium bicarbonate, 4-8 parts of dibutyl phthalate, 2-8 parts of diphenylamine, 2-4 parts of urea and 80-120 parts of distilled water. According to the anti-rust agent, the relatively long anti-rust time of the plates can be still kept in a place with relatively high humidity after the anti-rust agent is sprayed on the surfaces of the plates, and the drying effect is good.

Description

technical field [0001] The invention relates to the field of antirust on metal surfaces, in particular to an antirust agent for iron and steel plates. Background technique [0002] Iron and steel plates generally rust during the production process or the storage of finished products. In order to prevent surface corrosion, anti-rust treatment must be carried out; the current existing technology is to apply anti-rust oil on the surface of steel plates to form a layer of protection on the steel plates. Anti-rust oil film, so as to isolate the corrosion of metal by water vapor in the air, and achieve the purpose of rust prevention. However, the use of anti-rust oil needs to consume a large amount of oil raw materials, which will increase energy consumption and increase costs. Contents of the invention [0003] The object of the present invention is to provide an antirust agent for iron and steel plates, which can solve one or more of the above-mentioned problems in the prior a...
