Abstract

The invention relates to the technical field of coatings, and particularly discloses water-based phthalocyanine blue paste and a preparation method thereof. The water-based phthalocyanine blue paste comprises the following components in parts by weight: 25-35 parts of deionized water, 2-6 parts of a humectant, 15-30 parts of a dispersing agent, 0.1-1.0 part of a defoaming agent, 35-50 parts of phthalocyanine blue powder, 0.1-0.8 part of an anti-settling agent, 0.1-0.2 part of a bactericide and 0.1-0.3 part of a pH adjuster. The water-based phthalocyanine blue paste prepared by the invention isgood in fluidity, small in color difference, high in stability of the color paste itself, good in compatibility with a two-component polyurethane system, low in VOC (volatile organic compound) content, safe and environmentally-friendly, and has a relatively high practical value; and a pint film has an excellent surface effect after the paste is mixed with basic paint.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based phthalocyanine blue paste and a preparation method thereof. Background technique [0002] With the increasingly stringent national environmental protection policies, the use of solvent-based coatings has been restricted unprecedentedly, and high-performance, environmentally-friendly water-based coatings have developed rapidly. Two-component water-based polyurethane uses polyisocyanate as a crosslinking agent, and the formed paint film has a high crosslinking density, and the performance of the paint film can reach the level of solvent-based polyurethane. It is widely used in construction machinery, special vehicles, car repairs, and wooden furniture. And other areas with high decorative requirements. Due to the rich color of water-based two-component polyurethane topcoat, with the increase of output, the traditional paint making method cannot meet the needs of cus...
