Problems solved by technology

[0004] Metal devices are often subject to wear during use, thereby reducing their service life, and metal devices, especially large metal equipment such as punches, wear quickly when used with ordinary coatings, and the coatings are not strong enough. Therefore, there is a need for a metal surface. The coating can protect the metal from damage, and its own anti-rust and anti-corrosion performance is also very good

Abstract

The invention discloses a rust-proof metal coating and a preparation method thereof. The rust-proof metal coating comprises, by weight, 20-40 parts of ammonium lauryl sulfate, 10-60 parts of ribonucleoside triphosphote, 35-70 parts of titanium dioxide, 25-50 parts of polyethylene polyamine, 5-30 parts of sebacic acid, 15-50 parts of isopropanolamine, 40-80 parts of sulfitation, 25-35 parts of octadecanol phosphate sodium salt, 10-40 parts of polyester type carbamic acid ester, 30-90 parts of divinyl tetramine, 30-60 parts of tertiary butyl anthraquinone and 20-70 parts of surface active agent. The preparation method comprises the steps of evenly mixing the ammonium lauryl sulfate, the ribonucleoside triphosphote, the titanium dioxide and the polyethylene polyamine, then adding the octadecanol phosphate sodium salt and the polyester type carbamic acid ester and heating the materials to be at the temperature ranging from 80 DEG C to 90 DEG C so as to perform reaction for 20-30 min; adding the sebacic acid, the isopropanolamine, the sulfitation, the divinyl tetramine, the tertiary butyl anthraquinone and the surface active agent into water at the temperature ranging from 30 DEG C to 40 DEG C to be dissolved, then adding the mixture to perform even stirring. The rust-proof metal coating is good in rust-proof performance, foaming performance and overall performance and wide in application range.

Description

technical field [0001] The invention belongs to the field of mechanical processing materials, and in particular relates to an antirust metal coating and a preparation method thereof. [0002] Background technique [0003] Paint is a chemical mixture paint that can firmly cover the surface of objects for protection, decoration, marking and other special purposes. It is mainly composed of three basic substances: film-forming substances, secondary film-forming substances and auxiliary film-forming substances. Film-forming substances: also known as binders, most of the film-forming substances are organic polymer compounds such as natural resins (rosin, lacquer), paints (tung oil, linseed oil, soybean oil, fish oil, etc.), synthetic resins, etc. It is formed by high temperature reaction, and there are also paints composed of inorganic substances (such as: inorganic zinc-rich paint). Various film-forming substances are divided into xxx categories according to national standard...
