According to the development idea of "strengthening independent innovation, breaking key technology, strengthening technical integration, establishing standard system, expanding market scale and improving industrial efficiency", the products of plastic-wood composite materials should follow the integrated route, and form an independent product system. So that the performance of these products related to similar products or similar national standards, so that the application of wood-plastic composite materials have been recognized by quality inspection departments, which is more conducive to plastic-wood composite materials market development and application of the expansion. The following analysis from the perspective of the application of the construction industry problems.

1, China is currently on the stage of development of market economy, the recovery of plastic processing on the lack of professional bodies, the lack of separation, detection means. Because of the small size of domestic plastic products enterprises, it is difficult to form the number of corners of the waste, the scale and stability of performance in the old plastic market, domestic waste, industrial waste, modified materials, the second cycle or even multiple cycles Materials, and multi-component materials mixed together, can not be broken down, the basic properties of plastic and melt index is unknown, raw material recycling difficulties caused by wood processing difficulties, plastic / wood compatibility (adhesion) and mechanical strength Also have a great impact.

2, The market performance not only on the quality of competition, more price competition. In China's overall economy is still underdeveloped today, and sometimes people value the price even more than the quality, which is the initial stage of the market economy is a feature. Domestic plastic-wood enterprises, if the plastic is clearly uneconomical with genuine, if the use of recycled plastics, sources of instability, resulting in product performance instability, and because of the level of research, the filling of wood powder is generally about 30 to 60% , While the foreign can be as high as 80%. With the increase in wood-plastic products, the varieties of raw materials used are also varied, such as polyethylene, polypropylene, PVC, etc., filled with wood, bamboo, paper, cloth, rice husk, straw, , Of course, the compatibility of additives used are also different, so many differences will inevitably result in product performance (strength, stiffness, thermal properties, weather resistance, electrical properties, chemical properties, etc.) there are also very different.

3, Wood-plastic composite materials, national standards are not perfect, a lot of production and testing are reference to wood, plastic and even inorganic building materials testing standards, and seriously hindered the long-term development of plastic-wood industry. The experts have long suggested that the basis of foreign standards and the actual situation of domestic products, the development of scientific and rational production, testing and testing guidelines. Buildings that are self-retaining wall materials are currently not used. This type of building materials can be used to build the construction unit of simple dormitories, canteens and offices and mobile conservation houses and other buildings, can be modular lifting transport, easy assembly and disassembly. Although the development of wood-plastic products, there are some problems, but it can eventually solve a large number of plastic waste and other waste recycling is a matter of economic development, environmental protection are beneficial things.

At present, the domestic plastic-wood composite material design, manufacture has reached the international advanced level, many products have been exported abroad, China's wood-plastic composite materials in the international community have had a good impact. As the wood-plastic composite material has a simple wood and plastic can not match the many advantages, has been widespread concern at home and abroad. The material is green and environmentally friendly materials, can be recycled low-cost waste wood and plastic, using this technology to produce wood-based composite material can replace the use of wood, effectively alleviate the dilemma caused by China's forest resources. Plastic-wood composite materials production technology is in line with national economic development needs, but also in line with national industrial policy, and the use of a wide range of products. Therefore, we can believe that the wood-plastic composite material is a very promising material, is also a viable market prospects for the development of innovative technology, has broad market prospects, good economic and social benefits.
