Water-based color paste knowledge big explanation
In home life, we see a lot of colorful items are dressed up by color paste, and color paste is a kind of pigment concentrated paste, which is obtained through the surface treatment of different pigments, surface wrapping and other technical processing. Water-based color paste is one of the color paste.
One, the emergence of color paste
The traditional paint has many shortcomings, such as uneven coloring, coarse pigment particles, not coated with a smooth and delicate texture, easy to fade, chalking, pollution, etc.. Through continuous improvement, paint to the direction of low toxicity, low pollution, and the emergence of the current color paste, color paste by pigment or pigment and filler dispersed in the paint to form a semi-product. It has a variety of classifications. It embellishes our life, from small dressing to big house construction.
Color paste can be divided into different solvents: water-based color paste, oil-based color paste, water-oil general color paste, etc;
Color paste can be divided into: paint color paste, tape color paste, paper color paste, textile color paste, mechanical color paste, toy color paste, latex products color paste, etc. according to different uses.
Second, what is water-based color paste?
Compared with oil-based color paste, the solvent of water-based color paste is mostly water. It is a kind of pigment dispersion, which is the main coloring material of water-based plastic. Water-based color paste is better than oil-based color paste in terms of environmental friendliness. Good coloring, widely used in hotels, transportation, home and other aspects, currently mainly serves the paint industry.
Third, what are the main components of water-based color paste?
The main components of water-based color paste are generally composed of water, powder pigments (color powder), organic solvents, surfactants, humectants and so on. When special needs, some additives will be added to improve the performance. Color powder is the key component of the color paste, but also one of the more toxic components, and different additives, generally has a strong volatility, organic solvents are generally benzene, formaldehyde, etc., also contains toxicity.
Fourth, why choose water-based color paste?
Quality water-based color paste can be well compatible with water-based polymer latex body together, showing a uniform texture. Light resistance, weather resistance, chemical resistance, good UV resistance; finished water-based color paste coloring power, high fluidity; can be stored for a long time, not easy to caking and the formation of precipitates, and will not air dry; stable nature, stable viscosity, not easy to produce foam, not easy to mold, etc., low VOC index. With so many excellent performance, also makes the water-based color paste more and more general. In the home decoration also played is not negligible role.
