A kind of antirust flame retardant metal coating

Abstract

The invention discloses an antirust and flame-retardant metallic paint, which is mainly prepared from the following components: A) 98-103 parts by weight of iron oxide red powder; B) 48-53 parts by weight of aluminum tripolyphosphate; C) 78-83 parts by weight Parts of composite iron-titanium powder; D) 23-28 parts by weight of rutile titanium dioxide; E) 73-78 parts by weight of heavy calcium carbonate; F) 198-213 parts by weight of water; G) 28-33 parts by weight of propylene glycol; H) 18-23 parts by weight of film-forming aid; I) 398-403 parts by weight of metal paint emulsion; J) 7-12 parts by weight of leveling agent; K) 10-15 parts by weight of rheology agent; L) 0.5-4 Parts by weight of defoamer DK-3; M) 1-5 parts by weight of defoamer CF-16. The beneficial effects of the present invention are: no waste water and waste gas are produced during the preparation process, and it has environmental protection performance; and the combination of red iron oxide powder, aluminum tripolyphosphate and composite iron-titanium powder in the components can achieve a good function of rust prevention and rust prevention , and has non-toxic characteristics, it will not pollute the environment during production and use, and will not damage the health of production personnel and construction operators; the metal paint emulsion in the components can withstand high temperatures up to 800 ° C, so that Make the coating have high flame retardancy, so as to achieve fireproof effect.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a metal coating. Background technique [0002] Antirust coatings are used to coat metal surfaces to prevent metals from being oxidized and rusted during long-term use. The main requirements are that the coatings have the advantages of strong adhesion, good waterproof effect and fast drying. Anti-rust coatings widely used in traditional industries, the anti-rust raw material components are usually red lead, lead powder and chromate of zinc, lead or barium, and these components have strong toxicity, in the production of coatings and Can seriously pollute the environment during use, and damage the health of production and construction personnel; Therefore, many countries have passed legislation to prohibit the production and use of antirust paints containing red lead, lead powder and other components. [0003] At present, people have successively developed antirust coatings with a...

Anti-rust coatings widely used in traditional industries, the anti-rust raw material components are usually red lead, lead powder and chromate of zinc, lead or barium, and these components have strong toxicity, in the production of coatings and During use, it will seriously pollute the environment and damage the health of production and construction personnel; therefore, many countries have passed legislation to prohibit the production and use of antirust paints containing red lead, lead powder and other components

[0003] At present, people have successively developed antirust coatings with antirust raw material components such as zinc phosphate, aluminum phosphate, zinc molybdate, and calcium borate. Although these antirust raw material components have the characteristics of low toxicity, the antirust effect is not good. , not fireproof
