Surface-treated wood flour with physical reinforcing agent and vinyl chloride resin composition for the manufacture of synthetic wood with added wood flour

摘要

The present invention improves the compatibility with the resin by treating the surface with a physical property enhancer in the wood powder used to manufacture synthetic wood to replace natural wood in a wide range of fields such as door frames, window frames, flooring, moldings, etc. It's about wood flour.;In addition, the present invention in the vinyl chloride resin composition used in the manufacture of synthetic wood, by adding wood powder to the vinyl chloride resin to give the extrusion molding the appearance and surface texture similar to natural wood, reducing the shrinkage rate during molding of the molded article and also in processability In addition to the vinyl chloride resin processing methods such as welding and bending, not only the wood processing methods such as planer and nailing can be processed, but also the wood powder in the resin during kneading by using wood powder treated with the physical property enhancer. To improve the dispersibility and flowability of the molten resin during extrusion, and to increase the mechanical properties such as tensile strength, flexural strength and impact resistance of the molded article. Wood gas and cup such as carbon monoxide (CO) and carbon dioxide (CO ₂ ) This process eliminates the problem of corroding or shortening the life of extruding equipment by reducing wood gas, reducing the efficiency of extrusion molding, preventing surface roughness and pinhole phenomenon of extruded products, and easily corrupting molded products by residual moisture. The present invention relates to a vinyl chloride resin composition to which wood flour is added.
