What is the biomass wood plastic composite material?
Biomass Wood-Plastic Composites is a new type of environmentally friendly composite material in recent years.It is a composite material made of wood fiber or natural plant fiber as a enhanced phase, thermoplastic plastic as the base, which is made of melting, using heat pressure, extrusion, injection and other processing methods.
The raw materials of biomass wood plastic composite materials mainly include biomass fiber raw materials, thermoplastic raw materials, coupling agents and other additives. The most commonly used biomass fiber raw materials in biomass wood plastic composite materials are wood and crop fibers such as straw and other crop fibers. Thermoplastic plastic is mainly native and recycled polyethylene (PE), polypropylene (PP), and polyvinyl chloride (PVC). The coupling agent can improve the interface characteristics between the filler and the polymer material, improve the adhesion of the interface, and improve the performance of the composite material. Other additives mainly include light stabilizers, pigments, lubricants, preservatives, antioxidants, etc., which are used to improve processing performance and practical performance.
The performance characteristics of biological wood plastic composite materials
Good processing performance
Biomass wood plastic composite materials contain plastic and wood fibers, combining the flexibility of plastic with the rigidity of wood,It has a processing performance similar to the same wood, and the processing process is formed at one time to reduce the generation of waste. High utilization rate, its mechanical properties are significantly better than wooden materials.
Good mechanical performance
Wood fiber has rigidity. Increase in the fiber content in a certain range can improve the curved performance of composite materials, make the product difficult to deform and crack, and the durability is significantly higher than that of ordinary wooden materials. The surface of the product is high, generally 2 to 5 times the wood.
Good water resistance, corrosion resistance, long service life
Biomass wood plastic composite materials are much smaller than wood, and it is not easy to deform, antibacterial, light, and acidic and alkali. The stability and durability of biomass wood plastic composite materials, especially anti -microbial degradation capacity than wood.
Excellent adjustable performance
Plastics can change, foaming, solidification, modification, etc. under the action of other additives,In order to change the density and strength of biomass wood -plastic composite materials, it can also improve special properties such as anti -ultraviolet, anti -aging, anti -static, flame retardant and other special properties.
Raw materials are widely
Wooden fibers can be used for waste wood, wood processing, and crop straw, etc., with extensive resources.
Environmental protection
Wood powder, plastic and commonly used auxiliary agents of biological wood plastic composite materials are green and environmentally friendly types.There is no "three wastes" during its production and processing process. There is no harmful substance during use, and the material can still be recovered to a large extent after abandonment.
