Abstract

The present invention relates to a water-based metal rust inhibitor, which comprises the following raw material components by weight: 10-15% of boric acid, 40-50% of triethanolamine, 35-40% of dimethyl dodecanedioate, and the balance of water. According to the present invention, the used raw materials are environment-friendly and pollution-free; the product has the high concentration, and is usedafter mixing with water, such that the product is economical and durable; during the use, when the water-based metal rust inhibitor concentration is 1%, the damp heat box single sheet anti-rust time is more than 72 h, and the stacked sheet anti-rust time is more than 24 h; and the water-based metal rust inhibitor can be widely used for rush resistance of ferrous metals, and can be used as the anti-rust agent so as to be added to metal cleaning agents and cutting fluids.

Description

technical field [0001] The invention belongs to the field of chemical products, in particular to a water-based metal antirust agent. Background technique [0002] The main purpose of the antirust agent is to provide protection for the base metal and prevent the metal from being corroded to a certain extent. It is used as a primer before painting to improve the adhesion and anti-corrosion ability of the paint film. However, in the production process, there is a large amount of alkaline washing emulsified wastewater; rinsing wastewater; pickling waste liquid and other wastewater, and it is very troublesome to handle, wasting a lot of resources, and also causing environmental pollution. Therefore, the application of the present invention Provide a new environmental protection material, anti-rust material, replace the phosphating process, can meet the requirements of a small amount of discharge and non-toxic discharge. Contents of the invention [0003] The object of the pres...
