Problems solved by technology

However, the system contains resins, compatibility needs to be tested, otherwise it will easily lead to floating color of the paint, and the versatility of the product is greatly limited
At present, water-based color pastes are developing towards resin-free systems, so that the versatility of the system can be guaranteed; but how to make resin-free systems more stable, more environmentally friendly (APEO-FREE, VOC-FREE), and better moisture retention but a new challenge

Abstract

The invention provides water-based universal bright red color paste, which comprises, by weight, 5-15% of leveling agent, 5-15% of dispersing agent, 0.5-2% of nonionic wetting agent, 15-60% of water, 0.1-2% of mouldproof fungicide, 0.1-2% of thickening agent, 0.1-2% of pH (potential of hydrogen) regulator, 0.2-2% of defoaming agent and 29-45% of bright red powder. The water-based universal bright red color paste is prepared by means of reasonable match of the leveling agent, the dispersing agent and the specific wetting agent, is high in university, does not contain APEO (alkylphenol ethoxylates) but contains ultra-Low VOC (volatile organic compounds) (VOC<=2G / L), and can be used for color matching of emulsion paint and water-based wood lacquer.

Description

technical field [0001] The invention relates to the technical field of color paste, in particular to an environment-friendly water-based universal scarlet paste and a preparation method thereof. Background technique [0002] Water-based color paste refers to the uniform and stable organic or inorganic pigments formed under the wetting and dispersion of surfactants or water-soluble resins, with certain fluidity or thixotropic fluidity, and strong coloring strength. Concentrated pigment paste. There are two types of water-based colorants: one is a resin-free system with high pigment content; the other is a resin system with low pigment content, and the resin can be general-purpose resin or other single resin. Low pigment content has a resin system with a low pigment concentration, but it has good tinting strength, color development, fluidity and viscosity, and is widely used. However, the system contains resins, and experiments are required for compatibility, otherwise it wi...
