preparation example Construction

[0014] As the preparation method of the high-temperature protective aluminum powder coating described above, its component one preparation steps are as follows:

[0015] 1. Dry the pigments and fillers; all the pigments and fillers should be baked in a 110°C drying oven for 2 hours.

[0016] 2. Prepare the resin solution: weigh the resin, additives and solvent according to the ratio of the coating formula, and dissolve it into a uniform mixture;

[0017] 3. Weigh the raw materials; weigh various raw materials according to the proportion of the coating formula;

[0018] 4. Ingredients; put the weighed pigments and fillers into the container to mix, then mix with the resin solution, and stir evenly;

[0019] 5. Grinding: Put the evenly stirred slurry into a sand mill for grinding, and grind for 2 to 3 times in total. During the grinding process, gradually add the remaining solvent to the material to be ground, and form a component after grinding. ,Package.

Abstract

The invention belongs to the field of aviation paint technology, and relates to a high-temperature-resisting aluminum paint used on steel surfaces, and a preparation method thereof. The paint is composed of three components with a weight ratio of 100:3-10:5-20. A component one is composed of a film-forming substance, a pigment and filling material, an auxiliary agent, and a solvent according to a weight ratio of 40-70:5-20:1-5:20-50. A component two is polyamide resin. A component three is aluminum powder slurry. The paint has a good heat resistance, good hardness, good solvent resistance, and good salt spray resistance. When a coating formed by construction is held for 5h under a temperature of 300 DEG C, the coating is well-preserved. The pencil hardness of the coating is no lower than 2H. During part assembly, the coating can hardly get scratched. Under a normal temperature, the coating is not changed after 60d in water and 60d in oil. With a salt spray test of 2000h, the comprehensive performance of the coating is determined as grade 1.

Description

technical field [0001] The invention belongs to aviation paint technology, and relates to a high-temperature-resistant aluminum powder paint for steel surface and a preparation method thereof. Background technique [0002] Steel is one of the most important raw materials for the development of the national economy. It is consumed in large quantities every year in the fields of construction, automobiles, transportation, transportation, machinery, equipment, culture, and sports facilities. With the advancement of technology, the strength of steel is getting higher and higher, and high-strength steel is becoming more and more sensitive to impurity ions. When exposed to air, water and other environments, it is easy to be damaged by water, oxygen, and impurity ions. Corrosion. Steel corrodes faster at higher temperatures, so products made of steel must be protected with paint. [0003] High temperature resistant coatings generally refer to coatings that do not fall off when the ...
