Embodiment 1

[0036] Embodiment 1, embodiment 2, embodiment 3 see table one

[0037] A. raw material processing procedure, the hickory nut raw material is shelled, and the hickory nut shell that separates walnut kernel and walnut dregs is pulverized, sieved and dried, so that the moisture content of the hickory nut shell powder is less than 3.5%, and the crushing fineness is 80-120 mesh; surface treatment is carried out on the made pecan powder; the surface treatment is to dissolve the surface modifier with alcohol, the concentration is 5-8%, and the temperature is 40-60 ° C, the speed is 150-300 rpm / Every minute, add the surface modifier alcohol solution to the hickory shell powder and disperse for more than 30 minutes;

[0038] B. Mixing process: high-density polyethylene, polypropylene (or recycled materials), hickory shell powder or added part of wood powder (crushed to 100-120 mesh), talcum powder or light calcium carbonate (1000 mesh) in After mixing in a high-speed thermomixer to ...

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...
