Color paste for nanometer modified phthalocyanine machine and preparation method thereof

Abstract

The invention discloses a color paste for a nanometer modified phthalocyanine machine and a preparation method thereof. The color paste comprises the following raw materials in percentage by weight: 0-30% of phthalocyanine, 3-8% of aqueous grinding resin, 0-35% of aqueous nanometer concentrated pulp, 15-25% of wetting dispersant, 0.1-0.5% of pH value regulator, 0-15% of moisturizing cosolvent, 0.06% of anticorrosion antiseptic, 0.04% of defoamer and the balance of water, wherein the wetting dispersant does not contain volatile organic compound; all components are performed with quality detection, vacuum defoaming and filtering packaging after being mixed and ground to finally obtain the needed color paste for the nanometer modified phthalocyanine machine. The color paste for the nanometer modified phthalocyanine machine prepared with the preparation method of the invention has favourable intermiscibility with majority of emulsion paint, satisfies low VOC requirements, has favourable moisturizing property, favourable storage stability, low production cost, aqueous environment protection, strong generality and simple preparation process, and is easy for industrial production.

Description

technical field [0001] The invention relates to the field of water-based color paste, in particular to a nano-modified phthalocyanine pigment machine color paste for mechanical color adjustment and a preparation method thereof. Background technique [0002] With the rapid development of the paint industry, people choose paint not only for its decoration and protection, but also for the matching of paint colors. In order to meet people's needs for personalized color matching, well-known brand paint manufacturers continue to expand their sales channels in the civilian market , The fast and accurate on-site color matching service has become another highlight of retail stores in addition to brand benefits. Therefore, the development prospects of computer color matching systems (POS color matching systems) in the civil market for architectural coatings are becoming more and more promising. [0003] The color matching system is based on computer simulation technology. The color pa...

Problems solved by technology

[0005] At present, the content of volatile organic components (VOC), heavy metals, and nonylphenol polyoxyethylene ether (APEO) in commercially available water-based machine color pastes is relatively high. Most paint manufacturers have begun to introduce low-VOC or even zero-VOC basic latex paints. And the matching water-based machine color paste for the deployment of low-VOC and zero-VOC paints has become a vacancy in the market
