Water-like paint lecture hall: single-group, two-part and water-like UV paint

Single-pack water-like paint is often seen and applied in the market water-like paint products, is a truly environmentally friendly water-friendly paint, because single-pack water-like paint production after the completion of water dilution can be used directly, without any other additives. Water-based painted film matter is a polymerized polymerized emulsion or dispersion dispersed in the form of small particles. With the evaporation of water, emulsion particles close to each other, gather, compress each other, gradually merge and converg, the interface between particles disappears, and eventually form a continuous uniform paint film .
"
single-component water-based wood paint according to its main components can be divided into three categories:
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 the wood, but wear resistance and chemical resistance is poor, paint film hardness is soft, poor plumpness, comprehensive performance in general, membrane construction is not easy to produce defects. Suitable for water-like wood primer, matte finish. Because of its low cost and low technical content, is the majority of low-end water-color paint enterprises to the market's main products. This is also the formation of most people think that water-based paint is not good reason
2 acrylic and polyurethane synthesis
its characteristics in addition to adhering to the characteristics of acrylic paint, but also increased wear resistance and strong chemical resistance characteristics, some enterprises marked as water-based polyester paint. The hardness of the paint film is good, and the comprehensive performance is close to that of oily paint. Is the current national water-like paint to develop the backbone.
3 pure polyurethane water-based paint
its comprehensive performance is superior, high plumpness, high hardness of the paint film, wear resistance even exceeds oily paint, service life, color deployment have obvious advantages. It is a high-end product in water-like wood paint at a relatively high price.The advantages of single-pack water-like wood lacquer
With the progress of water-like wood lacquer technology, the performance of single-group water-coated paint is getting better and better, the paint film is flexible, transparent, dry fast, good adhesion, fine and soft paint film And beautiful, in the paint film plumpness, water resistance, hardness and scratch resistance on the above also have a significant improvement, can fully meet the cabinet, wall panels, bookshelves, display cabinets, beds and other facade system furniture coating needs. At present, a single group of watery wood paint in pine children's furniture and outdoor paint application is very mature, has accounted for more than half of the market share. At present, with the Burdink water-resistant paint and other water-like paint enterprises focus on the promotion and research and development of water-resistant door and window paint, water-resistant paint with breathable, breathable and impermeable; And its coating process and effect is gradually in line with the needs of wooden doors and windows, and now solid wood windows and aluminum wood windows water-like coating also ushered in a high-speed development period.
Insuffication of single-component water-based wood paint
water-based paint with water as a thinner, in the process 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-resistant paint is suitable for thinner, to make an open effect and semi-closed effect, so in the processing and grinding to be more fine, which requires furniture enterprises have a higher level of production technology.Because a single set of water-like paint depends on the natural volatile film of moisture, so the construction temperature, humidity has certain requirements, and the paint film is slow to do, cross-linking degree is not high formation of the paint film is not dense enough, the quality of the final film is not good Guaranteed, therefore, a single component of water-resistant paint film hardness and scratch resistance, resistance is not high, closed effect is not strong so single-component water-resistant paint is not suitable for coating furniture with high hardness requirements, such as tables, floors and other flat system coating. It is also difficult to close the upper float of grease for pine trees with a lot of grease.As far as the whole furniture industry is concerned, the quality of single-pack water-based paint is uneven, the effect will be a big gap, some poor quality low-grade water-based paint products affect the market's correct understanding and development of water-based paint, but single-group water-based paint as the main body of water-based paint, from raw materials to construction applications will be rapid development, to meet the needs of coating to get a wider range of applications.two-part water-based wood paint has better comprehensive performance than the common single-group water-based wood paint. It is because on the basis of a single group of water-based paint to add curing agent to assist in film formation, so that the film polymer chemical reaction, the formation of network structure, and eventually the formation of paint film, rather than relying on the natural volatile physical film, thus greatly improving the performance of the paint film.
The advantages of two-part water-based wood paint
because it is a chemical reaction into the film, so the comprehensive performance of the paint film has been significantly improved, especially water resistance, resistance, stain resistance, anti-adhesion, hardness resistance to scratching, iron resistance, wear resistance and other performance is more prominent. Paint film hardness can reach 2H, performance can be comparable with traditional PU oily paint. Therefore, it can be applied in the flat system furniture coating, to meet the hardness and scratch resistance needs. And can also be used as a closed primer and single-part water-related wood paint, effectively closed wood grease, tingate and so on.
The disadvantages of two-part water-like wood paint
Although the two-part water-like paint relies on curing agent to increase the performance of water-like paint film, but the environmental protection of water-like paint has a certain impact, although water-like paint curing agent also does not contain formaldehyde, benzene and other substances, but also increase some VOC emissions and odors. At the same time, the cost of coating two-pack water-like wood paint is more than double that of single-group water-hydrative wood paint. For furniture enterprises although the two-part water-like paint, that is, environmental protection performance can meet the requirements of furniture coating, but the increase in coating costs is difficult to make furniture acceptable.However, the cost of coating can be effectively controlled, Qumei furniture all furniture using water-based coating, Burtink water-based paint for its supporting two-part water-based paint, however, Qumei furniture coating costs only increased by about 30%, combined with the enterprise water-based coating application of the comprehensive cost than oily paint is not much higher. Burtinck water-based paint for Qumei furniture with the coating process, fully consider the problem of coating costs, the reasonable combination of the process can not only meet the needs of coating but also effectively control the cost of coating.UV paint, that is, UV-cured water-like wood paint, light trigger through ultraviolet light exposure to promote cross-linking reaction, and eventually form a paint film. Water-based UV paint combines the advantages of traditional water-based coatings and UV-cured coatings, water-based UV paint can be made into a true sense of zero VOC paint, although in most cases still need to add a small amount of additives to produce VOC problems, but compared to the use of active thinner photo-curing coatings, VOC content is greatly reduced.
advantages of water-based UV paint
Compared with traditional oily UV-cured coatings, water-based water-based UV paint has the following advantages: 1, water instead of active thinner, viscosity is easier to adjust.2, reduce the use of active thinners, so that its toxicity and irritation greatly reduced.3, water as a thinner can reduce the shrinkage rate of curing film, which is conducive to improving the adhesion of curing film to the substrate.4, you can get ultra-thin curing film, reduce the cost of coating.5, coating equipment and devices can be cleaned with water.6, can use relatively high molecular quality pre-polymer, overcome the traditional UV curing coating can not take into account the high hardness and high flexibility of the two problems.7, more suitable for spraying, increase construction flexibility.Compared with water-resistant paint, water-resistant UV paint has the following advantages: 1, in ultraviolet light can be quickly dried, speed up the coating efficiency2, paint film performance is excellent, high hardness can reach 2H, scratch resistance, strong resistance to scratches3, paint film fullness, easy to level, paint film adhesion.4, can achieve a two-part water-like paint film effect at the same time to ensure environmental protection.
Water-based UV paint shortcomings
water-based UV paint there is water, so compared to oily UV paint, before light curing, need to dry dewatering, in the photo-curing equipment needs to add flash steaming equipment, and the high evaporation heat of water leads to increased energy consumption, but also make the production time longer. And the light curing coating is only suitable for simple structure of flat coating, the shape of the structure of ultraviolet radiation can not be irradiated so can not do.At present, water-powered UV paint has begun to be applied in wood door coating, than oily UV paint has a higher environmental protection and flexibility, TATA wood door and Burtink water-type paint has been prepared for the wood door environmental protection coating, leading the new pattern of green environmental protection in the wood door industry.
