Antibacterial and lasting iron oxide red anticorrosive paint and making method thereof

Abstract

The invention discloses an antibacterial and lasting iron oxide red anticorrosive paint. According to the invention, common fenugreek seed straw is modified and then added into raw materials as a binder to improve the cohesiveness and affinity to a polymer, as the components contain chitosan, a lasting antibacterial effect can be achieved. In the invention, nano-silica and superfine iron oxide red powder are mixed evenly and then subjected to organic modification, on the one hand, the iron oxide red powder surface is organized to improve its lipophilicity and compatibility with organic matters, the easy agglomeration phenomenon of iron oxide red superfine powder is solved, also the water resistance and anticorrosive performance of the paint are also improved, and on the other hand, the inorganic SiO2 network of modified nano-silica and a polymer chain form a mutually cross-linked interpenetrating structure, thus inhibiting the motion of a polymer molecular chain, and improving the heat resistance of the paint. The prepared paint has the characteristics of strong cohesiveness, lasting antibacterial performance, water and damp resistance, no scaling and no shedding, and also can reach an air purification effect.

Description

Technical field [0001] The invention relates to the technical field of coatings, in particular to an antibacterial durable iron oxide red anticorrosive coating and a manufacturing method thereof. Background technique [0002] With the continuous development of my country's modern industry, especially in metallurgy, petrochemical, energy, new materials and military industries, there are more and more applications of high-temperature equipment and supporting facilities. Metal materials are easy to react with oxygen in the air in high-temperature environments. The oxidation reaction produces rust, which causes the metal material to gradually lose strength and cause structural loss, which becomes a hidden danger of various accidents. Therefore, the surface of high-temperature equipment generally needs to be coated with high-temperature anticorrosive coatings for protection to prevent oxidation and corrosion of metal materials and prolong the service life of high-temperature equipment....

Problems solved by technology

[0006] However, although the iron oxide red ultrafine powder has the advantages of small particle size, large specific surface area, strong surface activity, and fast chemical reaction speed, it also has thermodynamic instability and is prone to agglomeration, which seriously affects the application performance. , so we need to improve the dispersion performance of ultrafine iron oxide red powder; most of the commonly used binders in the prior art are organic or inorganic chemical binders, which are easy to fall off after being coated on the metal surface for a long time and still exist Corrosion of metals and hidden dangers of environmental pollution, the present invention also needs to improve the existing coating binder, optimize the existing production process and formula ratio, and then prepare a multi-functional environment-friendly iron oxide red anti-corrosion coating
