Abstract

The invention discloses wear-resisting iron oxide red anticorrosive paint. According to the wear-resisting iron oxide red anticorrosive paint, modified isolated soybean protein meal is added into raw materials by serving as an adhesive, and therefore the cohesiveness and the affinity of the paint with a polymer are improved; nano-silicon dioxide and ultrafine iron oxide red powder are mixed to be uniform and then subjected to organic modification, on one hand, the surface of the iron oxide red powder is organized, the lipophilicity and the compatibility of the paint with organic matter are improved, therefore, the phenomenon that the ultrafine iron oxide red powder is prone to agglomeration is prevented, and the water resistance and the corrosion resistance of the paint are improved, and on the other hand, an inorganic SiO2 network of modified nano-silicon dioxide and a polymer chain form a mutually-crosslinked interpenetrated structure, motion of the polymer molecular chain is inhibited, and the heat resistance of the paint is improved. The prepared paint is good in adhesive force, capable of resisting wearing, water and alkali, long-acting and durable, convenient to construct, simple in preparation method and capable of easily achieving large-scale production.

Description

technical field

[0001] The invention relates to the technical field of coatings, in particular to a wear-resistant 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 iron oxide powder. It has become the mos...

Embodiment Construction

[0015] A wear-resistant iron oxide red anti-corrosion coating, made of the following raw materials in parts by weight: epoxy resin 44, soybean protein isolate powder 5, wood fiber 6, high wear-resistant carbon black 4, sweet almond oil 3, hydroxyproline 2. Ketimine 3, aminosilane 7, sorbitan oleate 2, nano silicon dioxide 1.6, iron oxide red superfine powder 13, n-butanol 23.

[0016] The preparation method of described a kind of wear-resistant iron oxide red anticorrosion paint, comprises the following steps:

[0017] (1) Grind and mix soybean protein isolate powder and wood fiber evenly, add an appropriate amount of sodium hydroxide aqueous solution with a mass concentration of 1-2%, cook for 5-8 hours, cool and rinse with running water, add ketimine, high wear-resistant carbon Black and sweet almond oils are ultrasonically ground at 85-95°C for 1-3 hours, and dried to obtain modified soybean protein isolate powder;

[0018] (2) Heat and boil the aminosilane under the prote...
