[0026] The self-drying metal antirust paint is made of the following raw material components in parts by weight:

[0027] Raw material for pulping:

[0028] Pigment 5, propylene glycol phenyl ether 5, 2,2,4-trimethyl 1,3-pentanediol monoisobutyrate 5, anti-settling agent 3300S 1, leveling agent BYK-300 5, butyl hexanediol Acetate 2, LBCB-1 Thixotropic lubricant 4. Antimony trioxide 15, modified nano-attapulgite powder 8, modified water-soluble nano-scale silica sol 8;

[0029] Raw materials for paint mixing:

[0030] Water-soluble nano-scale silica sol 30, epoxy emulsion 10, phytate 25, styrene-acrylic emulsion 10, diisopropyl adipate 2, dispersant LBD-1 10, polyethylene glycol diallyl ether 2. Propylene glycol 50.

[0031] Modified nano attapulgite powder is prepared by the following method:

[0032] (1) Attapulgite powder is soaked in (0.8-1.2) g / L potassium permanganate solution for 2-3 hours, removed, washed with water until neutral, and then soaked in 2-5% sodium ph...

Abstract

The invention discloses air-dry metal anti-rust paint and a preparation method thereof. The air-dry metal 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 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 antirust paint, in particular to a self-drying metal antirust paint. Background technique [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 pollute the air and damage human health. Poor weather resistance is common, easy to fall off, and not suitable for complex and harsh environments. Contents of the invention [0003] The invention provides a self-drying metal antirust paint and a preparation method thereof, which have good mechanical stability, flexibility and surface hardness, and good weather resistance. [0004] Technical scheme of the present invention is: [0005] A self-drying metal antirust paint is characteriz...
