Technical Field

The invention relates to the technical field of color paste, in particular to a preparation method of novel environment-friendly color paste.

Background

The color paste is a pigment concentrated paste, is developed by using different pigments through the technologies of pigment surface treatment, surface coating and the like and strict processing technology, and is a semi-product formed by dispersing the pigments or the pigments and fillers in paint. According to the different solvents used by the color paste, the color paste is divided into water-based color paste, oil-based color paste, water-oil-used color paste and the like, and the oil-based color paste is called by taking pure oil as an adhesive. Resin paint is used as adhesive and is called resin color paste. The pigment and filler pulp which is formed by dispersing water as a medium and adding a surfactant is called water-based color paste. Because the paint types are various, the color paste types are also various. In order to better disperse pigments and the like in paints, it is often necessary to add small amounts of surfactants, such as zinc naphthenate and the like, during the manufacturing process. The color paste is cooperated with the natural color paste to dress the whole world, and the color paste is small enough to dress the whole world, daily use, toys and the like, and large enough to bridge, house and building and the like, and is not capable of showing the colorful colors.

As the domestic color paste factory is less than thirty, and because of the limitation of equipment, technology, capital and the like, the domestic real large-scale color paste factories are few, the demand of the domestic market for the color paste is far greater than the output of the factories (besides the color paste of the building coating, the color paste for rubber products, the color paste for PVC products and other civil and industrial color pastes, the demand for the color paste is much greater than that of the coating), the product quality is uneven, and the quality is still to be further improved.

The existing color paste is often added with organic adhesives, solvents and the like in the production process, has high toxicity and carcinogenicity, is easy to volatilize under the influence of environmental factors in the use process, is easy to cause environmental pollution, and is easy to be absorbed into the body by workers to cause body injury.
