Wood Plastic Door Research Report

The domestic wooden basic raw materials have gone through two generations: the first generation is wood and materials, and the second generation is plywood, fiberboard, particleboard, and wood pulp as representative man-made boards. In 2003, my country's wood-based panel output has ranked first in the world. The third generation is wood-plastic material, which has already shined in the market today. Wood-plastic material has the excellent properties of both plastic and wood, and has an absolute advantage in door panel materials. At present, the domestic wood-plastic market has huge potential. Although the annual output of wood-plastic products in the world is only a few million tons, since 1998, countries in Europe and the United States have increased at a rate of 65% each year.

China's chemical materials testing department has undergone strict inspections on the performance and environmental protection of the materials to ensure that the rights and interests of consumers are not harmed. It has good mechanical properties and can be machined like wood by sawing, planing, nailing, etc. It has the properties 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. After foaming, the uniform and regular cell structure can be passivated The elongation at break of the crack tip can be significantly improved. It is also an environmentally friendly material, with cheap and abundant raw materials, recyclable, which can reduce environmental pollution and protect forest resources.

The wood-plastic material 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 research group was established for this purpose. Wood-plastic composite materials and 5 The five themes in the field are related and occupy a place in cutting-edge technology and basic research. Wood-plastic composite material embodies the life characteristics of circular products originated from nature, superior to nature, used in nature, and attributed to nature.

In terms of operation, wood plastic, like logs, can be processed with solid wood, which can be nailed, drilled, planed, glued, and painted. The surface is smooth and delicate without sanding and paint. At the same time, wood-plastic paint has good adhesion, and consumers can paint according to personal preference. As a new type of wood substitute material, WPC can be widely used in building decoration and outdoor building materials and other fields, such as corner line, particle board, door and window line, wood plastic floor, flower garden fence, skirting board, ceiling line, blinds, stair railing , Decorative wall panels, outdoor pavilions, etc., most of the indoor and outdoor decorative building materials can be made of wood plastic. It is particularly worth pointing out that wood plastic has the function of waterproofing and fireproofing, so it can be used for decoration of kitchens, toilets, etc., which is beyond the reach of logs. Wood-plastic products have now attracted international attention and are known as green and environmentally friendly new materials, which will have broad development prospects.

A report analyzes that in 2005, North American plastic-wood composite outdoor decking and fencing accounted for 15% of the residential outdoor decking and fencing market. It is expected that the plastic-wood composite market will continue to maintain strong growth before 2010, and the market prospects for decking and fencing are particularly promising. But the growth in demand is not limited to these two applications, and other products have also grown correspondingly. According to the data provided by the report, in 2005, the turnover of construction products such as plastic wood outdoor decking in North America reached 495 million U.S. dollars, and it is expected to increase to 1,045 million U.S. dollars in 2008. From a global perspective, according to the research report of the American Principia Partners consulting company, it is estimated that the world plastic-wood composite material market will exceed 1.4 billion US dollars in 2007, and it will maintain a good growth momentum until 2010. The largest application is still extrusion construction products. However, it is expected that more types of plastic-wood construction products will appear, and the automotive and transportation industries are also markets that cannot be ignored for plastic-wood composite materials.
