Problems solved by technology

[0002] Color paste is an important part of paint. At present, the reaction temperature in the production process of color paste generally needs to reach about 170°C. After the production is completed, when carboxylic acid is added in the blending process, the temperature needs to be lowered to below 60°C. As a result, the energy consumption in the color paste production process is very large, and the production efficiency is also reduced due to the time required for heating and cooling

Abstract

The invention discloses a color paste for water-based paints and a production technique thereof, belonging to the technical field of anticorrosive paints. The color paste contains 2-5 wt% of oxides as an esterification reaction catalyst. The production technique comprises the following steps: adding the raw materials for producing the color paste and the 2-5 wt% of oxides into a grinding tank of a grinder, stirring uniformly, heating the materials, standing until the reaction of the raw materials finishes, grinding, and injecting into a finished product kettle; and after detecting the material in the finished product kettle, adding carboxylic acid and distilled water, blending, and stirring uniformly to obtain the color paste finished product. The production technique can lower the reaction temperature in the production process. The added oxides have the function of shortening the resin crosslinking time and leveling time, so that the paint film can be quickly dried, thereby enhancing the production efficiency and lowering the production energy consumption.

Description

technical field [0001] The invention relates to the technical field of anti-corrosion coatings, in particular to a color paste for water-based coatings and a production process thereof. Background technique [0002] Color paste is an important part of paint. At present, the reaction temperature in the production process of color paste generally needs to reach about 170°C. After the production is completed, when carboxylic acid is added in the blending process, the temperature needs to be lowered to below 60°C. As a result, the energy consumption in the color paste production process is very large, and the production efficiency is also reduced because it takes time to heat up and cool down. In addition, when water-based paint is used, it takes a certain amount of time for the paint film to be dehydrated and cured. Generally speaking, before the paint film is cured, it is easily damaged by external factors. Therefore, the shorter the curing time of the paint film, the lower th...
