Problems solved by technology

[0002] All kinds of mechanical equipment need to be coated with a layer of metal paint, on the one hand to increase the appearance, and on the other hand to prevent dust, rust and corrosion; the anti-rust paint in the prior art contains a large amount of volatile organic solvents, which produces a large amount of toxic and harmful Volatile gases that pollute the air and damage human health
Poor weather resistance is common, easy to fall off, not suitable for complex and harsh environments

Abstract

The invention discloses water-resistant and aging-resistant metal anti-rust paint and a preparation method thereof. The anti-rust paint is prepared from slurrying raw materials and paint mixing raw materials; a paint film formed by the anti-rust paint has high hardness, scratch resistance, strong adhesion, salt fog resistance, saline resistance, acid-base resistance, water resistance and oil resistance; the anti-rust paint can be used on the surface of an old paint film repeatedly; the damage to the paint film can be avoided; and the ultra strong toughness of the paint film can be guaranteed. The service life of the common paint film is 8 to 10 years.

Description

technical field [0001] The invention relates to a metal anti-rust paint, in particular to a water-resistant and anti-aging metal anti-rust paint. Background technique [0002] The exterior of all kinds of mechanical equipment needs to be coated with a layer of metallic paint, which on the one hand increases the appearance, on the other hand, it is dust-proof, rust-proof and anti-corrosion; the anti-rust paint in the prior art contains a large amount of volatile organic solvents, which produces a large amount of toxic and harmful of volatile gases that pollute the air and damage human health. It is common to have poor weather resistance, easy to fall off, and is not suitable for complex and harsh environments. SUMMARY OF THE INVENTION [0003] The invention provides a water-resistant and aging-resistant metal antirust paint and a preparation method thereof, which have good mechanical stability, flexibility, surface hardness and good weather resistance. [0004] The techni...
