Novel environment-friendly iron oxide red anti-corrosion paint capable of removing formaldehyde and preparing method of novel environment-friendly iron oxide red anti-corrosion paint

Abstract

The invention discloses a novel environment-friendly iron oxide red anti-corrosion paint capable of removing formaldehyde. According to the novel environment-friendly iron oxide red anti-corrosion paint capable of removing formaldehyde, wild kudzuvine root starch is modified and then added into raw materials as a binding agent, and thus the binding performance and the affinity of the paint with a polymer are improved; nano-silica and superfine iron oxide red powder are mixed and then subjected to organic modification, on one hand, the surface of the iron oxide red powder is organized, the lipophilicity of the iron oxide red powder and the compatibility of the iron oxide red powder with organic matter are improved, the phenomenon that the iron oxide red powder is likely to agglomerate is avoided, and the waterproof performance and the anti-corrosion performance of the paint are also improved; on the other hand, the inorganic SiO2 network of the modified nano-silica and a polymer chain form a mutual cross-linked interpenetrating structure, the movement of the polymer chain is restrained, and the heat resistance of the paint is improved; the prepared paint has good formaldehyde removing performance and durability of the formaldehyde removing effect, and the distilled water resisting and saline resisting effects of a coating also meet the practical use standards.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a novel formaldehyde-removing environmentally friendly iron oxide red anti-corrosion coating and a preparation 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, more and more high-temperature equipment and supporting facilities are used. Oxidation reaction produces rust phenomenon, which makes metal materials gradually lose strength and lead to structural loss, which becomes a hidden danger of various accidents. Therefore, the surface of high-temperature equipment generally needs to be protected by coating with high-temperature resistant anti-corrosion coatings to prevent oxidation and corrosion of metal materials and prolong the service life of high-temperature equipment. [0003] Iron oxide red, also known as rust red, is a red ir...

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
