Polyvinyl chloride wood-plastic flame retardance composite plate and preparation method

Abstract

The invention discloses a polyvinyl chloride wood-plastic flame retardance composite plate and a preparation method. The polyvinyl chloride wood-plastic flame retardance composite plate is prepared from the following raw materials in parts by weight: 100 parts of PVC (polyvinyl chloride) resin, 80 to 120 parts of bamboo powder, 5 to 15 parts of shell powder, 20 to 30 parts of nano calcium carbonate, 5 to 10 parts of aramid fiber, 3 to 6 parts of sepiolite fiber, 1 to 3 parts of a foaming agent, 0.5 to 2 parts of a plasticizer, 1 to 3 parts of a coupling agent, 0.5 to 2 parts of a composite antibacterial agent, 0.5 to 2 parts of a flame retardant, 1 to 3 parts of a stabilizer, 0.5 to 1.5 parts of methyl allyl polyoxyethylene ether, 0.5 to 1.5 parts of octaphenyl caged sesquiloxane, 1 to 3 parts of phytic acid and 0.5 to 1.5 parts of nonylphenol polyoxyethylene ether. The polyvinyl chloride wood-plastic flame retardance composite plate prepared by the preparation method has the advantages of high intensity, high impact property, wear resistance, weather resistance, heat resistance, difficulty in deformation, high stability, high flame retardance, good antibacterial effect and the like, and is good in processability; the process is simple, low in cost and high in production efficiency.

Description

technical field [0001] The invention belongs to the technical field of wood-plastic materials, and in particular relates to a polyvinyl chloride wood-plastic flame-retardant composite board and a preparation method thereof. Background technique [0002] PVC wood-plastic composite material is a new type of composite material made by using wood powder or other plant straws, seed shells and other powder materials and PVC resin as the main raw materials, adding various processing aids, mixing and molding. . It has excellent physical and mechanical properties, uniform physical properties, low water absorption, stable size, corrosion resistance, insect resistance and convenient processing. It can be molded and processed with general plastic processing equipment or after slight modification and can be reused Recycle. It is mainly used in furniture and decoration materials, building materials, outdoor materials and corrosion-resistant equipment. It is a good material for replacing...

AI Technical Summary

Problems solved by technology

When the wood-plastic board is used as a wooden floor, hardness and impact strength are two important concerns of those skilled in the art, but the performance of the wood-plastic board today is not perfect, such as low strength and hardness, low impact strength, poor Defects of poor wear resistance, antibacterial and flame retardant properties
