According to wood plastic equipment manufacturers, wood plastic composite (WPC) is a new kind of composite materials of green environmental protection, is to polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), acrylonitrile, butadiene and styrene copolymer (ABS) of recycled material and processing of scrap wood, sawdust, branches, crop straw or shell's plant fiber according to certain proportion, such as adding special additives, after high temperature and high pressure treatment made of synthetic materials. Therefore, wood-plastic composite materials can best reflect the advanced concepts of sustainable development such as circular economy, low-carbon economy, ecological environmental protection, resource conservation, energy conservation and emission reduction, and become the most dynamic new biomass composite materials for manufacturing wood-plastic special equipment. Wood plastic composite material production practice tells us that: although the wood fibre and herbaceous fibre is the basic material in the manufacture of the wood plastic composite, however, because of the wood fiber and herbaceous fiber material is qualitative different, its geometry is different also, in the actual production of wood fibre and herbaceous fibre filling amount is different, it may affect the mechanical properties of wood plastic composite, and the cost of production. In most areas, wood-plastic composites are basically made of wood powder fibres with mesh Numbers ranging from 20 to 40. As a result of fibre size of the fibre of this kind of wood, the powder is larger, grain of wood powder is very apparent, not only affected the evenness of wood powder in material, still bring about product appearance coarse, reduced the aesthetic feeling of material and adornment sex. And the wood that we undertake processing model product wood pink fineness can achieve 100~200 eye because this has fine close simple sense, the exterior is more beautiful. However, as the size of wood powder fibre decreases, its surface area will increase, which will increase the difficulty of wood powder treatment, wood plastic material production process conditions and equipment have higher requirements. At present, most of the wood-plastic composite materials produced on the wood powder particles are in the requirements of 40~80 mesh, this specification of wood powder fibre is more consistent with the majority of processing equipment and technology level, on the other hand, the surface treatment of the product is more convenient, can make the product has more close to the wood texture. It is worth paying attention to that, due to the advantages of wood-plastic composites such as aesthetics, good mechanical properties, low maintenance cost, non-degradable, termite resistance, flame retardant and so on, wood processing and biomass material fields at home and abroad are paying more and more attention. Therefore, in order to make wood-plastic products into the ranks of excellent biomass composite products, and has a certain advantage in cost-effective, we must solve the problem from the source of wood-plastic raw material production. According to the different needs of wood-plastic composite materials, the number and proportion of wood powder mesh of the two geometric shapes can be adjusted, which plays a certain exemplary role in the refinement and deepening of the research and development of wood-plastic materials.

Since the concept of wood plastic and product are brought into the market, also let a person find everything new and fresh really, bring new choice for a few enterprises and consumer, subsequently, the product of a few wood plastic Products in building materials market. The main wood-plastic materials are divided into PE wood-plastic and PVC wood-plastic two categories. PE wood-plastic products are mainly based on outdoor garden construction, such as guardrail, floor, garbage can, flower pool, tray and so on. PVC wood-plastic products are mainly indoor some decorative materials, such as doors, floors, foot line, door cover and so on. PE wood plastic materials are mainly secondary and tertiary PE recovery materials plus wood powder, calcium powder and a small amount of modifier. PVC wood plastic materials are mainly PVC resin powder, PVC recycling materials, wood powder, stone powder and some modifiers and so on. The preparation of PE wood plastic (PVC Ceiling Panel) products mainly adopts the cold promotion method, so each process is roughly similar. The cost control of finished raw materials depends on the content of filler, so the quotation is basically the same. The preparation of PVC wood-plastic products can be divided into vacuum moulding, cold push method, vacuum moulding is mostly low foam products, and the cost control of low foam wood-plastic products vary greatly, and the product quality (refers to the rigidity, toughness and tensile strength) vary greatly. As far as I am concerned, the development and production of wood-plastic products. first of all, are PE wood-plastic products. Its advantages and disadvantages are as follows: (1) PE wood-plastic material is excellent in water resistance and corrosion resistance; (2) PE has poor antioxidant and anti-light decomposition ability, and even the effect of adding antioxidant and UV absorber is not ideal, which can lead to poor product strength and colour fastness, and limited outdoor service life of the product; (3) it is easy to deform and bend when heated, but the effect of thickening or porous hollow structure is better; (4) the product surface colour is single, without wood sense, and the aesthetic effect is poor. In terms of these properties and characteristics of PE wood-plastic materials, I think trays, building templates, container pads and other places that are not exposed for a long time and where visual aesthetics is not required are more suitable for development and utilization. Secondly, the low cost of PVC wood-plastic products, good processing, surface decoration and other aspects of performance are taught PE wood-plastic superior, mainly in: (1) Washroom PVC Panel can be made of new or old materials, which is easy to modify. The amount of filling depends on the quality of the product; (2) PVC can be made into low-foaming wood-plastic products so that the cost is lower, the use of co-extrusion (double-material multi-material co-extrusion or steel-plastic co-extrusion), strength and wood grain sense is good; (3) PVC can be secondary processing of a variety of surface decoration or paint, including UV paint, beautiful products and good colour fastness; (4) the waterproof and anticorrosive property of PVC wood products is also superior. On the characteristics of PVC wood-plastic material, wood plastic products in interior decoration materials (such as floor, the line that play a base, decoration, door cover line, etc.), furniture, decorative plate with boards (such as furniture, etc.), building decoration materials (such as exterior wall hangs Taiwan, sound insulation board, wallboard, etc.), the botanical garden decoration materials (such as guardrail) with wood plastic and wood may be a promising direction of development.

WPC Floor is a new kind of environmental protection products, at the same time with woodiness sense and water-resistant anticorrosive properties, make it become a kind of excellent performance and very durable outdoor waterproof anti-corrosion materials, the wood plastic composite floor is very environmental protection. Its service life is longer, but also more affordable and environmentally friendly. 1. WPC floor is held concurrently with the characteristic of lumber and plastic, so it is waterproof performance is better not only, but moisture-proof performance is very good also. This is a good solution to the problem that traditional wood products tend to rot after encountering water. 2. The colour of the WPC floor is much more, it has the texture and texture of natural wood, and we can also customize the colour we like according to our own preferences. 3. The plasticity of the WPC floor is also relatively strong. It can be made into the shape we like when we use it. 4. The WPC floor is a kind of pollution-free floor, it does not contain benzene in the middle, and the content of formaldehyde only has 0.2. The wood plastic composite floor is Europe’s top environmental standards. We can also save on the use of wood in the manufacturing process. 5. Its fire resistance is also good. The fire rating is B1. In other words, it can be extinguished automatically after it encounters fire. And it doesn’t produce harmful gases. It effectively ensures the safety of the family environment.
