Water-based paint has the characteristics of being green, energy-saving, safe, and convenient to use. It has been rapidly developed in various countries of the world. Water-based paint as a pure environmental protection product diluted with water, is a new generation of high-tech Chaoyang products, compared with traditional solvent-based paints with low formaldehyde and low aromatic hydrocarbons. Many people do not understand water-based paints and cannot get rid of the misconceptions of solvent-based paints. They believe that water-based paints are not as good as solvent paints. In fact, the water-based paint adds water to dilute and does not dissolve the film-forming substance. The solvent-based paint is a dry film and is a parallel film. The water-based paint is a polymer film and is a thick film. The latter is truly advanced. Film, a high-tech product.
First, what is water-based paint
Water-based paint is water-based thinner, organic solvent-free paint, free of benzene, toluene, xylene, formaldehyde, free TDI toxic heavy metals, non-toxic, non-irritating odor, harmless to the human body, no environmental pollution, full paint film , Crystal translucent, good flexibility and has water resistance, wear resistance, anti-aging, anti-yellowing, fast drying, easy to use and so on. Any paint that uses water as a solvent or a dispersion medium can be called a water-based paint. Water-based paints include water-soluble, water-dilutable, and water-dispersible (latex paints).
1, water-soluble type: water-soluble type is a water-soluble resin as a film, represented by polyvinyl alcohol and its various modifications, in addition to water-soluble alkyd resin, water-soluble epoxy resin and inorganic polymer The aqueous resin.
2, water dilution type: water dilution type refers to the post-emulsion emulsion as a film preparation of the paint, the solvent-based resin dissolved in organic solvents, and then with the help of emulsifier by strong mechanical stirring to make the resin dispersed in water Emulsions, known as post-emulsions emulsions, can be diluted with water during construction.
3, water dispersion type: water dispersion mainly refers to the synthetic resin emulsion film as a preparation of paint. Emulsions are dispersed emulsions in which small groups of particles formed by the polymerization of unsaturated vinyl monomers under certain temperature conditions are dispersed in water in the presence of an emulsifier. The paint formulated by adding a little emulsion to a water-soluble resin cannot be called a latex paint. Strictly speaking, water dilute paint cannot be called latex paint, but it is customarily classified as latex paint.
Second, the difference between water-based paint and traditional paint:
1. Water-based paint is based on a variety of polymer resins, water is the dispersion medium, and special additives are added to make organics (filler pigments) and emulsion resin form a network structure; traditional paints use vegetable oils and synthetic resins as main film-forming substances. Supplemented by a variety of additives and pigments, there are fifteen major series, several varieties, the use of toluene, xylene and other organic solvents to be diluted.
2. Waterborne paint film is divided into several types: matt, glossy, and high gloss. It is resistant to alkali, acid, weather, salt, water, fire retardant, fast drying time, large covering area, and good rust and corrosion resistance. With rust and rust-proof effect, and the combination of the paint is good, can not afford any reaction; traditional paint film light and hard, water, weather, chemical resistance, electrical insulation is good but the paint film is brittle, long drying time Low-grade paint film is easy to yellow. Different paints are not suitable for combination because of their different performance.
3. Water-based paint is widely used on surfaces such as wood, metal, ships, cement, automobiles, etc. It is especially suitable for anti-corrosion and anti-rust of pipelines and equipments; traditional paints are suitable for different occasions and environments according to different characteristics.
4. The adhesion of water-based paint is higher than that of ordinary paint and can reach 1-2; traditional paint adhesion is 2-3.
5. The water-based paint shall be dry for 20 minutes and dry for 15 hours; the traditional paint shall be dry for 2 hours and the dry paint shall be for 30 hours or longer.
Summary: After reading so much information about water-based paints, everyone has a deeper understanding of water-based paints. What kind of paint should be used in the specific decoration process? Xiaobian thinks that it is necessary to analyze specific problems. If you want to learn more about water-based paint, you may wish to pay attention to the information on this site.
