Embodiment Construction

[0027] The metal coating is characterized in that it is made of the following raw materials in parts by weight:

[0028] Dodecenylsuccinic acid 185, propylene glycol 133, glycidyl methacrylate 212, octyl acrylate 364, methyl propylene glycol 433, phenolic resin 106, styrene 88, ethylenediamine 105, titanium dioxide 305, modified silicon Alginate 25, formic acid 7.5, water 102, sodium isethionate 15,

[0029] Described modified diatomite is prepared by the following method:

[0030] (1) First heat the diatomaceous earth at 105°C for 3 hours;

[0031] (2) Soak diatomite in 1.0g / L potassium permanganate solution for 2-3 hours, remove, wash with water until neutral, then soak in 9% sodium hydroxide solution for 3-4 hours, remove, Rinse with deionized water to be neutral;

[0032] (3) Calcining the washed diatomaceous earth at 425°C for 1-2 hours, and then grinding it into powder;

[0033] (4) Add 1-2% quartz sand nano-powder of diatomite quality, 2-3% silane coupling agent...

Abstract

The invention discloses a metal paint, which is prepared from the following raw materials in parts by weight: 180 to 190 parts of dodecenylsuccinic acid, 130 to 135 parts of propylene glycol, 210 to 215 parts of glycidyl methacrylate, 360 to 365 parts of 2-ethyl hexyl acrylate, 430 to 435 parts of methylpropanediol, 105 to 108 parts of phenolic resin, 85 to 90 parts of styrene, 100 to 110 parts of ethylenediamine, 300 to 310 parts of titanium dioxide, 20 to 30 parts of modified diatomite, 7 to 8 parts of formic acid, 100 to 105 parts of water, and 14 to 16 parts of sodium hydroxyethyl sulfonate. The raw materials are mixed, dispersed at a high speed, and grinded into nano-grade metal paint. The coating formed by the metal paint has the advantages of high hardness, scratch prevention, strong attachment, salt mist resistance, saline water resistance, acid and alkali resistance, water and oil resistance, recycling on oil paint film surface, paint film hurt prevention, super-strong paint film flexibility and the like. The service life of a conventional paint film can be between 5 and 8 years.

Description

technical field [0001] The invention relates to the field of metal coatings, in particular to a metal coating and a preparation method thereof. Background technique [0002] The appearance of various mechanical equipment needs to be coated with a layer of metal paint, on the one hand to increase the appearance, 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 metal coating and a preparation method thereof. The coating has good mechanical stability, flexibility and surface hardness, good weather resistance and high gloss. [0004] Technical scheme of the present invention is: [0005] A kind of metallic pai...
