1. acrylic water-based paint

The use of acrylic emulsion as the main component, the main feature is good adhesion, will not deepen the color of wood, but the wear resistance and chemical resistance is poor, the film hardness is soft, fullness is poor, comprehensive performance in general, film Good construction is easy to produce defects. It is suitable for water-based wood primer, matte finish. Because of its low cost and low technical content, is the majority of low-end water-based paint business to market the main products. This is also the reason why most people think that water-based paint is not good.

2. acrylic and polyurethane synthesis

Its characteristics in addition to adhering to the characteristics of acrylic paint, but also increased the wear and anti-chemical characteristics of the strong, better film hardness, comprehensive performance close to oily paint. Is the country's water-based paint to the development of the backbone.

3. pure polyurethane water-based paint

Its comprehensive performance, fullness, high hardness, high hardness, wear resistance even more than oily paint, service life, color deployment has obvious advantages. Is a high-end products in the water-based wood paint, suitable for high-grade solid wood furniture, the price is relatively high.

Water-based wood paint according to its film can be divided into three categories:

1. One-component water-based wood paint

Advantages: one-component water-based paint through continuous improvement, its performance is getting better and better, in the original film flexible, high transparency, fast drying, good adhesion, delicate film on the basis of soft, the film fullness, water Resistance, hardness and scratch resistance are also significantly improved, fully able to meet the wooden furniture plane and facade system coating needs. At present, one-component water-based wood paint in children's pine furniture, children's toys, outdoor furniture, the application has been very mature.

Disadvantages: water-based paint with water as a thinner, in the course of use will change the moisture content of wood, wood moisture content changes will lead to wood swelling, bending deformation, thus increasing the difficulty of water-based paint construction. In addition, water-based paint for thinner, made open and semi-closed effect, and thus in the processing of grinding to be more sophisticated, which requires furniture companies need to have a higher production process standards. As a single component of water-based paint by the natural evaporation of water film, so the construction temperature and humidity have certain requirements, and the film dry speed is slow, the degree of cross-linking is not high formation of the film is not dense, the final film Quality is not guaranteed, so the one-component water-based paint film hardness and scratch resistance is not strong. So the one-component water-based wood paint is not suitable for painting on the hardness requirements of high furniture.

Summary: the whole water-based wood paint industry, the current market, one-component water-based wood paint the quality of uneven, to do the effect is also a big gap, some low-grade low-grade water-based paint products affect the market for water-based paint Understanding and development, but one-component water-based wood paint as the backbone of water-based wood paint, in the national environmental policy to encourage, will quickly sweep the paint market. Faced with fierce competition, high-quality water-based wood paint business will be surfaced, water-based single-component coating applications will be more extensive.

2. Two-component water-based wood paint (water-based PU paint)

Advantages: due to chemical reaction film, so the overall performance of the film have been significantly improved, especially water resistance, chemical resistance, stain resistance, anti-adhesion, hardness, anti-scratch, high temperature, wear resistance and other performance More prominent. Film hardness can reach 2H, the performance can be comparable with the traditional PU oil paint. So it can be applied to the hardness of the higher requirements of the furniture coating. And can also be used with a single component of water-based wood paint to reduce the cost of furniture business.

Disadvantages: Although the two-component water-based paint to rely on curing agent to increase the performance of water-based paint film, but the environmental impact of water-based paint have a certain impact, although the water-based paint curing agent does not contain formaldehyde, benzene and other substances, but also increased Some VOC emissions and odor. At the same time, two-component water-based wood paint coating costs than single-component water-based wood paint at least twice as high. Especially for those who have just received oil to change the water, their workers have not fully adapted to the construction of water-based paint, to do the effect is often unsatisfactory, so many companies on the two-component water-based wood paint also hold wait and see attitude.

Summary: Two-component water-based wood paint than the common one-component water-based wood paint has a better overall performance. Is due to the addition of a solid agent on the basis of a one-component water-based paint to help film, so that the film-forming polymer chemical reaction, the formation of network structure, and ultimately the formation of paint film, rather than rely on the natural evaporation of moisture film Greatly improving the performance of the film.

3. water-based UV paint

Advantages: water-based UV paint that is UV-curable water-based paint, relying on ultraviolet light film, to promote the film more closely cross-linked to speed up the drying to improve painting efficiency, excellent film performance, hardness up to 2-3H, water-based paint Environmental performance can be fully retained.

Disadvantages: water-based UV paint the need for UV light curing equipment, and water-based UV paint in the presence of water, so compared to oily UV paint, in the light curing, the need for dry water, in the light curing equipment need to add flash equipment , While the high heat of water led to increased energy consumption, but also to extend the production time. Photo-curing coating is only suitable for large-scale mechanized production structure Simple flat coating flat plate type of sheet construction, shaped structure UV can not be irradiated to, so the main application in the wooden doors and other flat system coating.

Summary: Water-based UV paint combines the advantages of water-based paint and light-cured coatings, in recent years has been rapid development, but also the future development of light-cured coatings one of the main direction. Water-based UV paint close to zero VOC emissions, more conducive to environmental protection, and has a fast curing rate characteristics, in line with the requirements of the times, in Europe and the United States and other developed countries have been widely used.
