Problems solved by technology

However, no matter whether steel materials are used or placed in the atmospheric environment for a long time, they will gradually undergo chemical or electrochemical reactions with the surrounding medium, causing surface corrosion
Slight corrosion can make the surface lose its metallic luster and reduce precision. In severe cases, rust pits will appear on the surface, which will deteriorate or even break the mechanical properties of steel products and affect their service life.

Abstract

The invention discloses a solution for antirust based on nano-ceramic materials and a preparation method thereof. The solution is a mixed solution prepared from various components, and the mass of each component in every 600 grams of the mixed solution is expressed in grams. The unit meets: 3-(2,3-glycidoxy) propyltrimethoxysilane, silane hydrolyzate, ethyl silicate, sodium metasilicate pentahydrate, nano ceramics, silica sol, sodium carbonate, sodium gluconate , sodium citrate, isopropanol, and the balance is deionized water. In the present invention, by adding the nano-ceramic material into the silane solution for rust prevention, the added nano-ceramic material forms a hard layer on the surface of the silanized composite film on the metal surface, thereby improving the oxidation resistance of the metal surface, abrasion resistance.

Description

technical field [0001] The invention belongs to the technical field of metal surface treatment, in particular to a solution for antirust based on nano-ceramic materials and a preparation method thereof. Background technique [0002] Iron and steel materials have high strength and hardness, as well as good plasticity and processability, so it is the most widely used structural material in the world today. However, no matter whether steel materials are used or placed in the atmospheric environment for a long time, they will gradually undergo chemical or electrochemical reactions with the surrounding medium, causing surface corrosion. Mild corrosion can cause the surface to lose its metallic luster and reduce precision. In severe cases, rust pits will appear on the surface, which will deteriorate or even break the mechanical properties of steel products and affect their service life. According to reports, in industrially developed countries, the annual loss due to corrosion of...
