Hickory nut shell ecologic wood composite material and preparation method thereof

Abstract

The invention relates to a plastic-wood composite material and provides a hickory nut shell ecologic wood composite material and a preparation method thereof. The hickory nut shell ecologic wood composite material is prepared from following components including, by weight, 50-60 parts of a thermoplastic high-molecular resin, 40-50 parts, or 30-40 parts, of hickory nut shell powder, 10-20 parts of wood powder, 8-10 parts of light calcium carbonate, 10-14 parts of a compatilizer, 2-4 parts of a thermal stabilizer, 2-4 parts of a lubricant, 2-3 parts of a plasticizer, and 1-3 parts of an antioxidant and an ultraviolet stabilizer. A comprehensive technology comprising deep process of raw materials and extrusion moulding and the like is employed. Deep process waste of wild hickories and waste plastic resources are employed. The composite material in the invention has dual-characteristics, which exist in common plastic-wood, of wood and plastic, is better in mechanical performances and is more rigid, durable, wear-resistant and weather-resistant. The method is simple and convenient, is low in manufacturing cost, can be recovered and recycled, can save energy resources and can protects environment.

Description

technical field [0001] The invention relates to a polymer-based wood-plastic composite material and a preparation method thereof, in particular to a hickory shell ecological wood composite material and a preparation method thereof. Background technique [0002] The per capita annual consumption of wood in the world is 0.58 cubic meters, while that in my country is only 0.29 cubic meters. my country's annual demand for forest wood and its products is equivalent to more than 300 million cubic meters of resource reserves, while the annual reasonable supply of existing forest resources only accounts for the demand. About 60% of. On the other hand, in the next 5-10 years, the average annual net increase of the national population will be about 11 million, and the annual economic growth rate will be over 7%, which puts forward higher requirements for the already poor timber supply. There is a shortage of timber in the world, the self-sufficiency rate of Australia and the United St...

AI Technical Summary

Problems solved by technology

Hickory nuts have few edible parts and many shells, and a large amount of concentrated hickory shells are discarded or burned, resulting in a great waste of resources and seriously polluting the environment
