[0002] Resin color paste is one of the raw materials used in the production of paint. The resin color paste used in the production of water-based paint must have good water solubility. Otherwise, the color paste will float in the water after the paint is mixed with water, which will cause the coloring effect of the paint. Very poor; in addition, during the production of resin color paste, it is easy to produce shrinkage cavities, which will lead to a decline in product quality, and will also lead to uneven paint film when the paint is used in the later stage; moreover, the production of resin color paste During the process, heating and heat preservation are required so that the reaction between the various raw materials can proceed normally, but during the heating and heat preservation process, the solvent is easy to volatilize, resulting in waste of production raw materials and environmental pollution, which brings losses and inconvenient

Embodiment 1

[0031] A kind of resin color paste, is made of following raw material:

[0032]

[0033] The production process includes the following steps:

[0034] Step 1: Add the prescribed amount of isooctyl alcohol and propylene glycol methyl ether into the epoxy kettle where the epoxy resin is melted, then add the prescribed amount of CYD epoxy resin, and feed the cooling water into the epoxy kettle and the condenser on the reaction kettle .

[0035] Step 2: Keep warm when the temperature rises to 80°C. After the epoxy resin in the epoxy kettle is completely melted, open the lid of the kettle and observe to confirm that it is completely melted.

[0036] Step 3: put the melted epoxy resin into the reaction kettle, when the temperature of the reaction kettle rises to 80°C, start stirring, add ethylenediamine and diethanolamine, and keep the temperature for 2 hours.

[0037] Step 4: After the heat preservation is completed, add the polyamine resin, raise the temperature to 100°C, and...

Abstract

The invention discloses a resin color paste and a production process thereof, belonging to the technical field of anti-corrosion coatings. The resin color paste includes 260-330 parts of epoxy resin, 130-160 parts of alcohol ether solvent, 60-80 parts of isooctyl alcohol, 35 parts of ~50 parts of diethanolamine and 100~200 parts of polyamine resin are dispersed in 10~20 parts of deionized water through chemical reaction and mixing, and the above parts are all measured by weight. Its production process includes melting of epoxy resin, addition of raw materials and heat preservation reaction. In the production process of the resin color paste of the present invention, the loss is less, the production cost is reduced, and the anti-shrinkage effect is good, the quality of the product is improved and the hydrophilicity is strong; the production process of the present invention makes the ring opening of the epoxy resin moderate, avoiding The waste of raw materials increases the water solubility of epoxy resin, eliminates the shrinkage cavity of the product, and improves the product quality.
