High-efficient rust-proofing agent

Abstract

A high efficient antirust which consists of the following component by weight ratio: water 200-300 share, orthophosphoric acid 80-160 share, sodium nitrate 0.5-4 share, zinc oxide 1-6 share, ammonium bichromate 1-5 share, tertiary sodium phosphate 1-8 share, sodium molybdate 0.01-1 share, hydroxypropyl methylcellulose 1-8 share, divinyl ether 1-4 share. It's high efficient antirust with great performance, strong penetrability and strong adhesive power.

Description

Technical field: [0001] The invention relates to a metal surface treatment agent, in particular to an efficient rust-removing and anti-rust agent. Background technique: [0002] Rust removal and rust prevention of metal products has always been an important issue for technicians in the related surface treatment industry. The invention patent with the application number 01131523.7 discloses a rust-removing and anti-rust solution, which includes phosphoric acid, potassium dichromate, potassium nitrate, zinc oxide, sodium phosphate, sodium molybdate, and hydroxymethylcellulose. But the patent application also has some substantive problems. For example, the production raw materials are poisonous, unable to prevent oil and decontamination, the penetration is not strong, and there are many raw materials in the component, which cannot achieve a more ideal effect. Potassium dichromate is poisonous and environmentally friendly. In addition, as metal products, the construction envi...

AI Technical Summary

Problems solved by technology

If the production raw materials are poisonous, it cannot prevent oil and decontamination, the penetration is not strong, and there are many raw materials in the component, which cannot achieve a more ideal effect.

Potassium dichromate is toxic and not environmentally friendly

In addition, as metal products, the construction environment of some equipment is harsh, and dust and dirt are common, and mechanical products themselves need to deal with oil. Difficult to remove and prevent rust

Due to the lack of penetration, the aforementioned background technology products cannot penetrate into the original layer of steel, and can only cover the surface of the steel without decontamination and oil removal, so rust removal and anti-rust cannot achieve the desired effect

Moreover, in the process of use, it is necessary to wipe off the dust and oil stains first, which is time-consuming and laborious. For those large buildings, such as towers and bridges, the ideal anti-rust effect cannot be achieved.
