Wood plastic door research report
- Aug 20, 2018 -

Domestic wooden basic raw materials have been used for two generations: the first generation is wood and sawn timber, and the second generation is wood-based panels represented by plywood, fiberboard, particleboard and wood pulp. In 2003, China's wood-based panel production ranked first in the world. The third generation is wood-plastic materials, which have now shined in the market. Wood-plastic materials combine the excellent properties of both plastic and wood, and they have an absolute advantage in the door panel materials. At present, the domestic wood-plastic market has great potential. Although the annual output of wood-plastic products is only several million tons, since 1998, countries in Europe and the United States have increased at a rate of 65% per year.


China's chemical materials testing department has undergone rigorous testing of the performance and environmental protection of this material to ensure that the interests of consumers are not harmed. It has good mechanical properties and can be sawed, planed, nailed and other mechanical processing like wood. It has the characteristics of hardness, toughness, durability and wear resistance. After foaming, a large number of uniform and regular cells are formed, which can save the cost of the product. Experiments show that compared with unfoamed PVC/wood powder composites, the density after extrusion foaming can be reduced by 50%, up to 0.6g/-1.0g/cm3. The evenly structured cell structure after foaming can be passivated. The elongation at break of the crack tip can be significantly improved. It is also an environmentally friendly material. The raw materials are cheap and rich, and can be recycled, which can reduce environmental pollution and protect forest resources.


The wood-plastic materials project entered the "2002 High-Tech Development Report" of the Chinese Academy of Sciences; in the same year, it was included in the "863" project and the "948" plan of the Ministry of Science and Technology, and a wood-plastic project group, wood-plastic composite materials and 5 The five themes of the field are related and have a place in cutting-edge technology and basic research. Wood-plastic composites reflect the life characteristics of recycled products that originate from nature, are superior to nature, and are used for nature and return to nature.
