Abstract

The invention relates to a preparation method of a solvent type nano phthalocyanine coloring agent for UV vacuum plating paint. The coloring agent is composed of the following components in percentage by weight: 12% to 35% of hydroxy acrylic resin, 8% to 25% of wetting dispersant, 15% to 30% of phthalocyanine pigment, 0.1% to 0.5% of defoaming agent, and 40% to 70% of solvent. The particle size (D50) of the prepared nano phthalocyanine coloring agent is controlled in a range of 50 to 160 nm. The coloring agent has the characteristics of good storage stability, strong coloring power, high transparency, good compatibility, high temperature resistance, and aging resistance, is environment-friendly, is capable of replacing the metal complex dyes, is suitable for being used as a transparent coloring agent for UV vacuum plating paint, and can also be used as a surface coloring agent for children toys, wooden furniture, leather products, plastic products, metal products, aluminum foil, copper foil, food package materials, and the like.

Description

technical field [0001] The invention relates to a solvent-type nano-phthalocyanine colorant, in particular to a nano-phthalocyanine colorant suitable for UV vacuum coating coatings, high temperature resistance, high transparency and capable of replacing metal complex dyes. Background technique [0002] Vacuum coating mainly uses vacuum evaporation, sputtering, ion plating and other methods to coat metals, alloys and compounds on the surface of materials or products to form the coating required by the product. Vacuum coating technology has been widely used in various fields such as electronics, aerospace, optics, magnetism, construction, machinery, packaging, decoration, etc., and is playing an increasingly important role. Vacuum coating is a vapor deposition method, and organic coatings are usually formed by curing the coated organic polymer coating solution, and are widely used in the protection and decoration of plastic and non-ferrous metal substrate surfaces. There are ...
