Preparation technology of wood-plastic composite material

Abstract

The invention discloses a preparation technology of a wood-plastic composite material. The preparation technology comprises the following steps: 1), mixing mulberry branch fiber with recycled plasticparticles and an auxiliary agent at high speed / low speed, and then adding into a double-stage (double-screw / single-screw) mixing unit for performing extrusion granulation to obtain wood-plastic composite material masterbatch; 2), adding the wood-plastic composite material masterbatch into an extrusion moulding machine for extruding a wood-plastic composite plate material. By the preparation technology, large-scale utilization of mulberry branches can be achieved.

Description

technical field [0001] The invention relates to a fiber preparation process, in particular to a wood-plastic composite material preparation process. Background technique [0002] A large number of mulberry branches are not fully utilized, which wastes resources on the one hand and causes environmental pollution on the other hand. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention proposes a wood-plastic composite material preparation process capable of realizing large-scale utilization of mulberry branches. [0004] The present invention achieves technical goals through the following technical solutions. [0005] The wood-plastic composite preparation process is improved in that it includes the following steps: [0006] 1) Mix mulberry fiber with recycled plastic particles and additives at high speed / low speed, and then add them to a double-stage (twin-screw / single-screw) mixing unit for extrusion granulation to obtain wood-plas...
