Description
Technical Field
The invention relates to the technical field of wood-plastic composite material processing, in particular to a flame-retardant smoke-suppression type high-mechanical-property flame-retardant PVC/PE (polyvinyl chloride/polyethylene) -based wood-plastic composite material and a preparation method thereof.
Background
The wood-plastic composite material is a novel composite environment-friendly material which mainly takes wood plant fibers as filling or reinforcing materials and thermoplastic plastics as a matrix. The wood-plastic composite material has the advantages of simple preparation process, high color degree, repeated processing and utilization and the like, and is widely applied to the fields of furniture, decoration, decks, gardens, automobile parts, buildings and the like. Common thermoplastic polymer substrates in life comprise Polyethylene (PE), polystyrene (ABS), polypropylene (PP), polyvinyl chloride (PVC) and the like, and the wood is generally selected from rice hull powder, poplar powder, straw powder and the like. The PVC-based wood-plastic composite material is more popular with people due to good color and luster degree and high flame retardance, people have a rising demand for the PVC wood-plastic composite material year by year, and compared with other wood-plastic composite materials, the PVC-based wood-plastic composite material has higher cost, and cannot be well blended and melted with wood powder mainly due to poor processing flowability and ductility of PVC resin. In order to reduce the production cost of the PVC-based wood-plastic composite material, the low-cost wood-plastic composite material is prepared by adopting a PVC and PE blending method, and the mechanical property of the PVC/PE-based wood-plastic composite material is poor because PVC and PE are not compatible easily. Chlorinated Polyethylene (CPE) is prepared by chlorination reaction of PE with high crystallinity, and the chlorine content and chlorine atom distribution on the molecular chain of the CPE are different, so that the molecular chain of the CPE is not chlorinated, and the lengths and the amounts of residual PE crystalline chain segments are different. Thus, both un-chlorinated residual PE chains and chlorinated segments similar to the PVC molecular structure are present on the CPE molecular chain. From molecular structure analysis, CPE with appropriate chlorine content and residual crystallinity should be compatible with both the PVC and PE moieties. Therefore, CPE is selected as a compatibilizer of PVC and PE and is used for preparing the PVC/PE-based wood-plastic composite material with high mechanical property.
Because the PVC/PE-based wood-plastic composite material contains a large amount of PVC, a large amount of toxic smoke is accompanied during combustion, and the personnel casualty is easily caused during fire. Therefore, it becomes more important to improve the smoke suppression performance of the PVC/PE-based wood-plastic composite material
