1.One-component water-based wood paint
One-component water-based paint is a water-based paint product that is often seen and applied in the market. It is a truly environmentally friendly water-based paint, because after the production of one-component water-based paint is completed, it can be diluted with water and can be used directly without any other additives. The water-based paint film-forming substance is a polymer emulsion dispersed in water in the form of small particles. With the volatilization of water, the emulsion particles approach each other, aggregate, compress each other, gradually merge and coalesce, and the interface between the particles disappears, finally forming a continuous and uniform paint film.
Advantages of one-component water-based wood paint
With the advancement of water-based wood paint technology, the performance of one-component water-based paint is getting better and better, the paint film is flexible, high transparency, fast drying, good adhesion, fine and soft and beautiful. There are also significant improvements in paint film fullness, water and chemical resistance, hardness and scratch resistance. It can fully meet the furniture painting needs of cabinets, wall panels, bookshelves, showcases, beds and other facade systems. At present, the application of one-component water-based wood paint in pine children's furniture and outdoor paint is very mature, and it has occupied more than half of the market share.
At present, with water-based paint and other water-based paint enterprises focusing on the promotion and development of water-based door and window paint, water-based paint has the characteristics of breathability and impermeability. High ductility and toughness; Long-lasting weather resistance and other characteristics that these oil-based paints do not have, can protect wooden doors and windows for a longer time to cope with the test of indoor and outdoor environments. And its coating process and effect also gradually meet the needs of wooden doors and windows, and now the water-based coating of solid wood windows and aluminum wood windows has also ushered in a period of rapid development.
Disadvantages of one-component water-based wood paint
Water-based paint uses water as a diluent, which will change the moisture content of the wood during use. The change in the moisture content of the wood will cause the wood to swell and bend, thus increasing the difficulty of water-based paint construction. In addition, water-based paint is suitable for open effect and semi-closed effect, so it needs to be more finely processed and polished, which requires furniture companies to have a higher level of production technology.
Since the one-component water-based paint relies on the natural volatilization of water to form a film, there are certain requirements for the construction temperature and humidity. In addition, the drying speed of the paint film is slow, the degree of cross-linking is not high, the paint film formed is not dense enough, and the quality of the final film is not guaranteed. Therefore, the film hardness, scratch resistance and chemical resistance of the one-component water-based paint are not high, and the sealing effect is not strong, so the one-component water-based paint is not suitable for painting furniture that requires high hardness, such as tables and floors.
As far as the entire furniture industry is concerned, the quality of one-component water-based paints is uneven at present, and the effect produced will be very different. Some low-quality and low-grade water-based paint products have affected the market's correct understanding and development of water-based paints, but One-component water-based paint, as the main body of water-based paint, will develop rapidly from raw materials to construction applications, and will be more widely used to meet the needs of painting.
2.Two-component water-based wood paint
Two-component water-based wood paint has better comprehensive performance than common one-component water-based wood paint. It is because the curing agent is added to the one-component water-based paint to form a paint film, so that the film-forming polymer undergoes a chemical reaction to form a network structure, and finally a paint film is formed, rather than relying on the natural volatilization of water. Thereby improving the performance of the paint film.
Advantages of two-component water-based wood paint
Due to the chemical reaction film formation, the comprehensive properties of the paint film have been significantly improved, especially the performance of water resistance, chemical resistance, stain resistance, blocking resistance, hardness, scratch resistance, hot resistance, wear resistance and other properties. The hardness of the paint film can reach 2H, and its performance can be comparable to that of traditional PU oil-based paint. Therefore, it can be completely applied to the furniture coating of the flat system to meet the requirements for hardness and scratch resistance. And it can also be used as a sealing primer and one-component water-based wood paint to effectively seal the oil, tannin, etc. of wood.
Disadvantages of two-component water-based wood paint
Although the two-component water-based paint relies on the curing agent to increase the film performance of the water-based paint, it has a certain impact on the environmental protection of the water-based paint. Although the water-based paint curing agent also does not contain formaldehyde, benzene and other substances, it will also increase some VOCs Emissions and odors. At the same time, the coating cost of two-component water-based wood paint is at least twice as high as that of one-component water-based wood paint. For furniture enterprises, although the two-component water-based paint is environmentally friendly and can meet the requirements of furniture painting, the increase in painting cost is difficult for furniture to accept.
However, the cost of painting can be effectively controlled. When Haisun water-based paint matches the two-component water-based paint for customers, it fully considers the problem of painting cost and reasonable collocation of processes, and does its best to meet the requirements of the paint. It can effectively control the coating cost.
