Embodiment Construction

[0013] specific implementation plan

[0014] The present invention will be described in detail below through specific examples.

[0015] A metal epoxy protective paint, prepared from the following raw materials in parts by weight (kg): urethane acrylate 40, amino resin 30, E-12 epoxy resin 40, trimethylolpropane triacrylate 6, styrene 1. Blocked isocyanate (TS280) 2. Ethylene glycol monobutyl ether 2. Calcium naphthenate 3. Titanium dioxide 10. Kaolin 6. Iron red powder 2. Copper powder 1. Zinc powder 2. Benzoin dimethyl ether 4. Acetic acid Ethyl ester 9, dispersing aid 3.

[0016] The dispersing aid is prepared by the following method: the parts by weight (kg) of each raw material component are: diatomite 200, nano-carbon 4, jade powder 12, zinc gluconate 2, ascorbic acid 1, pentaerythritol triacrylate 1 , zirconium fluoride 1, alum 3, octylphenol polyoxyethylene ether 1, silane coupling agent KH550 1; the preparation method is to add diatomaceous earth to 12-15% hydrochlo...

Abstract

The invention discloses a metal epoxy protective paint which is prepared from the following raw materials in parts by weight: 40-45 parts of urethane acrylate, 30-42 parts of amino resin, 40-45 parts of E-12 epoxy resin, 6-8 parts of trimethylolpropane triacrylate, 1-2 parts of styrene, 2-3 parts of enclosed type isocyanate (TS280), 2-3 parts of ethylene glycol monobutyl ether, 3-4 parts of calcium naphthenate, 10-12 parts of titanium dioxide, 6-8 parts of kaolin, 2-3 parts of iron oxide red powder, 1-2 parts of copper powder, 2-3 parts of zinc powder, 4-5 parts of benzoin dimethyl ether, 9-12 parts of ethyl acetate and 3-4 parts of dispersing auxiliary. According to the dispersing auxiliary, the optical performance is improved, so that the paint is uniformly dispersed, and the stability of the paint is maintained. The metal epoxy protective paint has extremely strong corrosion resistance, rust resistance and saline-alkaline resistance, is high in hardness, resistant to scratch, simple in preparation process, overcomes the defects of the traditional epoxy paint and is especially suitable for back face protection of a metal plate.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof, in particular to a metallic epoxy protective paint and a preparation method thereof. Background technique [0002] As an important coating, epoxy paint is widely used in the coating anti-corrosion process due to its good anti-corrosion performance. Can be used as primer and intermediate coat for metal products. [0003] Metal corrosion is the result of chemical or electrochemical reactions between the surface of the metal and the medium in the surrounding environment from the surface to the inside, causing the metal to be damaged and lose its original properties. People have studied various measures to prevent and inhibit the corrosion of metals, among which coating anti-rust is an effective method. Since steel accounts for 95% of metal usage, and 70% of steel is used in an atmosphere that is prone to rust, so preventing steel from corroding in the atmosphere is the main task of ant...
