Light ageing resistant low-cost renewable polyvinyl chloride (PVC) foamed composite material and preparation method thereof

Abstract

The invention discloses a light ageing resistant low-cost renewable polyvinyl chloride (PVC) foamed composite material and a preparation method thereof. The light ageing resistant low-cost renewable PVC foamed composite material is a foamed material prepared by compositely processing a macromolecular substance and other materials. The light ageing resistant low-cost renewable PVC foamed composite material is characterized by being prepared from the following raw materials in part by mass: 100 parts of PVC, 4 to 10 parts of foaming stabilizer, 0.5 to 2 parts of foaming agent, 0.4 to 1.0 part of auxiliary foaming agent, 0.05 to 0.2 part of foaming agent aid, 5 to 10 parts of processing aid, 0.5 to 2.5 parts of lubricant, 0.5 to 1.0 part of light stabilizer, 0.5 to 1.0 part of auxiliary light stabilizer and 30 to 50 parts of activated wood meal, bamboo flour or rice husk. The light ageing resistant low-cost renewable PVC foamed composite material is suitable for outdoors, has excellent mechanical properties, is added with a great amount of wood meal and the like, and can be recycled; and the preparation method for the recyclable light ageing resistant low-cost renewable PVC foamed composite material has the advantages of small equipment investment, simple manufacturing process, and low production cost.

Description

technical field [0001] The invention is a light-aging resistant, low-cost, renewable PVC foaming composite material and a preparation method thereof. It belongs to the foaming material which is compounded and processed by high molecular material and other materials. Background technique [0002] Polyvinyl chloride foam composite material is a new type of composite material made by using wood powder or other plant straw, seed shell 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-resista...

AI Technical Summary

Problems solved by technology

Generally, in this case, the coupling effect of wood powder is poor, and the number of wood powder added to the material should not be too much, otherwise it will easily cause uneven dispersion of wood powder in the resin, or the combination of wood powder and PVC resin body is not good. , resulting in a decrease in the mechanical properties of the material
