Water-based paint is a coating that does not contain organic solvents and uses water as a diluent. Compared with other types of paint, water-based paint has no formaldehyde inside, which is a relatively environmentally friendly paint. Water-based paint can be divided into water-soluble, water-dispersed and water-dispersed types. So, is water-based paint toxic? What are the advantages and disadvantages of water-based paint?
First, water-based paint characteristics, is water-based paint toxic?
1, acrylic acid as the main component of water-based wood paint, its main characteristics are good adhesion, will not deepen the color of wood, but wear resistance and chemical resistance is poor. Because of its low cost and low technical content, it has become the main product on the market.
2, based on the synthesis of acrylic acid and polyurethane as the main component of water-based wood paint, its characteristics in addition to adhering to the characteristics of acrylic paint, but also increased wear resistance and chemical resistance characteristics.
3, it is a complete polyurethane water-based lacquer coating, its wear resistance even reaches several times that of oil-based paint, for water-based paint products, the technology is only a few professional companies to master.
Water-based paint is very convenient to use, not easy to appear bubbles and other common problems of oily paint; Waterborne wood paint has low harm and low pollution. Because it is water-soluble paint, no poison, so environmental protection; Waterborne wood paint is not easy to turn yellow and has good water resistance.
Two, the advantages and disadvantages of water-based feel paint
1, water-based paint with water as the solvent, saving a lot of resources, greatly reducing the construction of fire hazards; Air pollution is also greatly reduced. A small amount of low toxic alcohol ether organic solvent was used to improve the working environment.
2, water-based paint on the construction process and the surface cleanliness of the material requirements are very high, if the cleaning is not very clean, then the effect of water-based paint will be greatly affected.
3, the coating tool of water-based paint can be cleaned with water, which saves the consumption of washing solvents. Isn't that a lot of money? The adaptability of water-based paint to the surface of the material is particularly good, and the adhesion of the coating is very strong.
4, water-based paint is corrosive to the coating equipment, need to use anti-corrosion lining or stainless steel material, equipment cost is high. The corrosion of water-based coating on the pipeline, metal dissolution, so that dispersed particles precipitation, coating film pitting, also need to use stainless steel pipe.
5. Electrophoresis coating is uniform and smooth. Good flattening; The inner cavity, weld, edge and edge parts can be coated with a certain thickness of film, with good protection; The electrophoretic coating has good corrosion resistance, and the salt spray resistance of thick film cathodic electrophoretic coating can reach 1200h.
Water-based paint has advantages and disadvantages, we can see their own situation, relatively speaking, water-based paint is still better. I hope you found the above helpful.
