Water-oil universal color paste and preparation method thereof

Abstract

The invention relates to the field of coatings and provides a water-oil universal color paste prepared by a reasonable dispersant system. A hydrophilic nonionic surfactant is used as a first dispersant, and a second dispersing agent synergistically interacting with the first dispersing agent is adopted, so that a pigment can be sufficiently dispersed in a water-oil system. At the same time, wateris adopted as a main solvent, and the paste is environmentally friendly and free of toxicity. The color paste production cost is reduced. A preparation method of the water-oil universal color paste isfurther provided. The process is simple and feasible and easy to popularize.

Description

technical field

[0001] The invention relates to the field of coatings, in particular to a water-oily universal color paste and a preparation method thereof. Background technique

[0002] Color paste is a concentrated pigment paste, which is prepared by using different pigments, through surface treatment and packaging of pigments, and through specific processing techniques. Color paste is a semi-finished product made of pigment or pigment and filler dispersed in paint. The oil-based color paste with pure oil as the adhesive is called oil-based color paste, and the pigment-filler paste dispersed with water as the medium is called water-based color paste. Oil-based colorants can only be applied to oil-based systems, and water-based colorants can only be applied to water-based systems; when an enterprise produces oily and water-based products at the same time, it is necessary to purchase water-based colorants and oil-based colorants separately, causing great harm to the enterpr...
