Embodiment 1
[0018] The new durable wood-plastic composite board is made of the following raw materials in parts by weight: seven-type polyvinyl chloride 50, wood powder 25, polyvinyl chloride recycled material 40, active calcium 20, calcium zinc stabilizer 3.8, polyethylene wax 0.35, saturated fat Alcohol dicarboxylate 0.65, methyl methacrylate 8.5, ACM 4, MBS 4, oxidized polyethylene wax 0.25, diisopropyl azodicarboxylate 0.23, poly-4-methyl-1-pentene 4, chlorine PVC 8, glass fiber 5, ABS high rubber powder 4. The preparation method of novel durable wood-plastic composite board comprises the following steps:
[0019] (1) Put the seven types of polyvinyl chloride, wood flour, recycled polyvinyl chloride and active calcium into the mixing pot at a temperature of 80-90°C and stir at high speed for 5-8 minutes to fully evaporate the water Finally, put the remaining auxiliary materials into the mixing pot and mix together to 120-130°C, then put them into the cold mixing pot and cool to 60°C;...

Abstract
The invention discloses a novel durable plastic-wooden composite sheet material, which comprises the following raw materials: VII PVC, wood powder, a polyvinyl chloride reworked material, active calcium, a calcium-zinc stabilizer, polyethylene wax, an internal lubricant, a foam adjusting agent, ACM, MBS, oxidized polyethylene wax, a polyvinyl chloride (PVC) foaming agent, poly-4-methyl-1-pentene, chlorinated polyvinyl chloride, glass fiber and ABS high glue powder. Compared with a traditional plastic-wooden composite sheet material, the novel durable plastic-wooden composite sheet material adds the ABS high glue powder, a MBS impact modifier, glass fiber and the like, thereby the product can reach the usage function, and has toughness, rigidity and elasticity, and the flexural modulus of the product can reach 2000MPA. The novel durable plastic-wooden composite sheet material can fully embody the advanced concepts of sustainable economic development such as circular economy, resource utilization, healthy and environment protection, conservation and substitution and the like, the problem of white pollution caused by waste plastic without treatment, recovery and utilization can be effectively solved, and the novel durable plastic-wooden composite sheet material enables comprehensive utilization of resources and a function of the environment protection.
Description
technical field [0001] The invention relates to a novel durable wood-plastic composite board, which belongs to the technical field of wood-plastic composite material processing. Background technique [0002] As we all know, my country is a country short of timber, with a forest coverage rate of only 14%, far below the world average of 25%. Coupled with years of disorderly mining, my country's recoverable resources are extremely scarce. At the same time, the waste of wood processing and utilization is serious and the benefits are low. Therefore, new materials must be used to supplement the material vacancy caused by the limitation of wood. Wood-plastic composite board is a new material with excellent performance, economical and environmental protection. It is made by adding special additives to waste plastics and processed waste wood, including sawdust, crop straw, peanut shells, rice husks, etc., after high temperature and high pressure treatment. into structural panels or ...
