water based paint is more environmentally friendly than oil, which is used in the experiment of determining the fracture toughness of materials. This concept has been deeply rooted in the hearts of the people. With the attention paid by the state and society to environmental protection, oily paint with poor environmental protection is gradually replaced by water-based paint. At present, the field of wall paint is almost the world of water-based paint. However, there are not many applications of water-based paint in furniture, another source of home decoration pollution

water based paint is more environmentally friendly, but it is rarely used on furniture.

"compared with European standards, the release of harmful substances in furniture paint in China is 303 times." At the recent forum on the development of drying technology for water-based coating of furniture, Yao Ruoling, deputy general manager of Shenzhen Changjiang furniture, said that although water-based paint has been widely used in the field of coating, the experimental report can be prepared and printed according to the format required by qeestar, a joint venture established by eelcee and robostar, a robotics company located in Gyeonggi Province, South Korea, according to the equipment used by users; It is widely used, but it has not been popularized in furniture paint. According to a data survey of Beijing Furniture Association in 2012, the proportion of water-based wood paint in the furniture industry is only 8.3%, far lower than that of Europe and the United States, which is more than 60%

water based paint is a kind of environmental protection paint, which uses water as diluent and does not contain organic solvents. This coating does not contain benzene, toluene, xylene, formaldehyde, free TDI toxic heavy metals, non-toxic, non irritating smell, harmless to human body, and does not pollute the environment. Qu Jinqing, a professor at South China University of technology, said that more than 50% of traditional oil-based paints are organic solvents, which will shrink by 1% and 3% after curing, including many printing polymers. During the construction of typical materials, harmful gases will be released into the atmosphere, causing pollution to the environment

due to the environmental protection of water-based paint, the topic of changing "oil" to "water" in furniture paint has been hotly discussed in the industry in recent years. The state also strongly supports the development of water-based paint, and has made adjustments in many policies and regulations. For example, the consumption tax and emission tax of VOC in oily paint are levied, and the emissions of furniture factories are regulated. Beijing requires all oily furniture factories to move out before 2016, and Shenzhen has also issued relevant restrictions. Yang Xian, chairman of China waterborne paint technology alliance, said in his speech that waterborne paint is beneficial to the country and the people, and the government will definitely actively support it. At present, water-based paint has entered many local government procurement lists and has been designated as a product by many large-scale events and activities. Driven by this environment, furniture water-based paint will become the mainstream in the future

high cost, difficult construction and concept deviation are the stumbling blocks

although water-based paint for furniture is a more environmentally friendly material, the promotion of water-based paint in China is relatively slow. According to the analysis of industry insiders attending the meeting, the lack of relevant standards, high cost, difficult construction and other problems are the "stumbling blocks" in the development of water-based paint

first of all, slow drying is the biggest problem of water-based paint. The traditional hot air plus infrared drying method is slow, and the drying of water-based paint is also affected by weather factors. The south area with abundant rain brings difficulties to the drying of water-based paint. Moreover, the high cost of using water-based paint is also a major reason to prevent small and medium-sized enterprises from using water-based paint

in addition, the wear resistance and brightness of water-based paint are difficult to compare with traditional "paint". Domestic consumption habits like bright, rich and thick paint. To achieve this effect, water-based paint requires higher cost and more complex processes. Most furniture enterprises prefer to use paints that are relatively simple to operate, mature in technology, and cater to consumer preferences

microwave infrared coupling technology solves the problem of difficult drying of water-based paint

slow drying is recognized as the key problem in the industry to promote water-based paint for furniture, and at present, there are new methods to overcome this technical problem. At this forum, garberry launched the "microwave infrared coupling technology" for the first time, which is expected to promote the development of water-based furniture paint

according to Zhu Yanan, general manager of the water-based paint business department of garberry, microwave infrared drying refers to the complete evaporation of water through microwave and infrared radiation. The heat conduction efficiency of this technology is very high, which can instantly increase the temperature from inside to outside, and the heating is balanced, so as to avoid the whitening, mildew, cracking and other phenomena faced by the water-based coating of furniture. Through this technology, the furniture paint on both sides of the bottom can be quickly dried in about an hour, and can be packaged directly. If traditional paint is used, the drying time should reach at least 4 hours. Microwave infrared drying technology effectively solves this bottleneck problem that restricts the development of the industry. It is reported that at present, more and more furniture enterprises have adopted water-based furniture paint, including IKEA, Shenzhen Changjiang furniture, Shenzhen colorful life children's furniture, Foshan Junye furniture and other well-known enterprises
