Polyurethane materials for furniture keep an eye on environmental innovation

At the polyurethane material furniture application conference hosted by the China Polyurethane Industry Association and co-organized by Fujian Tianjiao Chemical Materials Co., Ltd., which concluded in Quanzhou on May 17, participating representatives discussed polyurethane materials Application development status and trends in the furniture industry. Facing the huge furniture application market and consumers’ increasing environmental protection requirements, polyurethane materials urgently need to increase green technology, product research and development and promotion efforts, improve product performance, expand application fields, and meet market demand.

Furniture air pollution problem is prominent

Yin Chao, executive deputy secretary-general of the All-China Federation of Industry and Commerce Furniture and Decoration Chamber of Commerce, said that my country’s building materials and furniture market currently has a total market The scale is 4.5 trillion, of which furniture accounts for about 40%. Currently, China’s upholstered furniture output value accounts for approximately 47% of the world’s total. It is estimated that the output value of China’s upholstered furniture industry in 2018 was approximately US$26.9 billion, and the sales revenue of the upholstered furniture manufacturing industry was 89.9 billion yuan.

While the market is growing steadily, air pollution has become one of the stubborn diseases in the furniture industry. Song Guangsheng, director of the National Indoor Vehicle Environment and Environmental Protection Product Quality Supervision and Inspection Center and China Indoor Environment Monitoring Working Committee, said that furniture pollution is quite serious and is one of the three major indoor environmental pollution problems in my country. Divided according to polluting substances, including formaldehyde pollution, VOCs pollution, benzene pollution, odor pollution, microbial pollution, etc. Among them, the formaldehyde pollution problem of artificial boards and solid wood furniture is the most serious because of its wide source, long time, serious harm and difficulty in solving.

According to Song Guangsheng, in recent years, my country has introduced the “Indoor Wall and Wood Repainting Service and Acceptance Procedures” “Evaluation of Combustion Performance of Upholstered Furniture Mattresses”, “General Technical Conditions for Wooden Furniture”, “Limits of Formaldehyde Release in Artificial Panels and Products of Interior Decoration and Renovation Materials”, “Limits of Hazardous Substances of Interior Decoration and Renovation Materials” and other standards stipulate that consumers are concerned about home environmental protection. The issue has also received unprecedented attention, and environmental standards for furniture will be tightened in the future. It is urgent to innovate and develop new pollution-free furniture materials.

Polyurethane new technology products attract attention

Han Baole, deputy secretary-general of the China Polyurethane Industry Association, said that polyurethane materials have a wide range of applications in the furniture field, including sponges. Polyurethane materials are found in coatings, adhesives, synthetic leather, and boards. There is an urgent need to improve material application performance and standards, especially to improve environmental protection levels. The industry must further increase the research and development and promotion of green technologies and products, improve product performance, expand application areas, and meet market needs such as furniture.

Song Guangsheng said that in terms of polyurethane materials for furniture, new formaldehyde-free artificial boards that can replace urea-formaldehyde glue, TDI that replaces urea-formaldehyde glue, and new water-based PU leather that replaces traditional leather furniture should be vigorously promoted. Environmentally friendly technology products.

In recent years, aldehyde-free artificial boards have gradually emerged, including plywood, fiberboard and particleboard, as well as blockboard . Zhu Ruidong, deputy general manager of Guangdong Hanhong Wood Industry Co., Ltd., said that the total market demand for formaldehyde-free artificial panels is expected to exceed 2 million cubic meters in 2019, and the compound annual growth rate is expected to exceed 50% in the next few years. Taking MDI as the formaldehyde-free Fiberboard and particleboard produced from raw materials will become mainstream products. The artificial panel industry will become the main demand market for MDI.

The development of environmentally friendly products is in full swing

Faced with the increasing market demand for environmentally friendly products, polyurethane companies are stepping up their efforts to develop environmentally friendly polyurethane materials for furniture .

<span style="font-size: 16px" Simai has developed a series of formaldehyde-free two-component polyurethane adhesive products. It combines polyurethane adhesive with traditional technology to produce formaldehyde-free solid wood composite flooring, which has the characteristics of formaldehyde-free and formaldehyde-free solid wood composite flooring.It has the advantages of excellent bonding performance, low VOCs content, and wide application of boards.
