Composite water-soluble multicolor paint

Abstract

A composite aqueous colorful coating comprises a composition A and a composition B. The coating is characterized in that the main ingredients of the coating include aqueous film forming material, filling, surfactant, aqueous resin, polysaccharide derivative, pigment, polymerization promoter, anti-mould agent, protective adhesive and water. Due to introduction of the polysaccharide derivative into preparation of the coating, lipophilic association and charge interaction between high molecular water-soluble polymers and the surfactant in water can form colloidal complexes of even higher molecular weights by which a colorful coating with patterns of different sizes and colors is produced so that particles cut by machines have excellent stability, and even when the pigment content is high, problems such as color bleeding and missing, which appear in the prior art, do not occur.

Description

technical field [0001] The invention relates to the paint industry in the field of chemical industry, in particular to a combination of environment-friendly water-based colorful paint widely used in the construction industry and a preparation method thereof. Background technique [0002] Looking back on the development of water-based architectural coatings in the past ten years, it can be roughly divided into four types: water-in-oil, oil-in-oil, oil-in-water, and water-in-water. The first three types are mainly composed of oily particles and aqueous medium. Most of the oily media used in the oily particles require a large amount of organic solvents, so that it will inevitably cause harm to people and the environment during construction and application. Therefore, it is necessary to develop environmentally friendly low-pollution water-based products that use water as the medium instead of organic solvents. Coatings, especially colorful coatings, should be the development di...

Problems solved by technology

[0003] my country's building exterior wall decoration has always been dominated by ceramic tiles, mosaics, marble, etc. During their use, the single color of the facing bricks is not conducive to the improvement of the city's beautification function, and what is more serious is the adhesive used for bonding the facing bricks to the wall. It will age, and there are safety hazards such as damage and falling, and even smashing people, which not only seriously affects the appearance of the city, but also is quite difficult to repair

The problem of paint products as such decorative substitutes is that the existing interior and exterior wall paints in my country have a single color tone and lack of change. It is urgent to adopt technological innovation and new product development to meet the needs of market diversification, human culture, and individualization.

The water-based colorful paint disclosed by domestic patents has water-in-water aromatic colorful pattern paint, such as Chinese Patent Publication No. CN1097782A, and water-in-water type colorful pattern paint, such as Chinese Patent Publication No. CN1117509A, from the decorative patterns that can be formed by these coatings From the point of view, it can only be regarded as some colorful paints that can make small patterns, and cannot become a colorful paint that can make large patterns with good storage stability, so it can not meet the needs of the market.
