A continuous fiber cloth three-dimensional reinforced wood-plastic composite material and its production method and equipment

Abstract

The invention discloses a continuous fiber cloth three-dimensional reinforced wood-plastic composite material and a production method and equipment thereof. The reinforced wood-plastic composite material comprises a wood-plastic core layer; a wood-plastic surface layer is arranged outside the wood-plastic core layer, and thermosetting resin impregnated fiber cloth is arranged on at least one sidebetween the wood-plastic core layer and the wood-plastic surface layer. Experimental data show that the transverse / longitudinal bending property, the transverse / longitudinal tensile property, the transverse / longitudinal impact property, the transverse / longitudinal creep property, the compression property in the thickness direction, the dimensional stability of boiling at 100 DEG C and the surfacehardness of the reinforced wood-plastic composite material in some embodiments of the invention are remarkably improved.

Description

technical field [0001] The invention relates to a reinforced wood-plastic composite material and its manufacturing method, in particular to a continuous fiber cloth three-dimensional reinforced wood-plastic composite material and its production method and equipment. Background technique [0002] As a green and environmentally friendly composite material, wood-plastic composite materials mainly use thermoplastic polymers such as polyethylene, polypropylene, and polyvinyl chloride to replace the usual resin adhesives, and more than 35%-70% of wood powder, rice husk, and straw Waste plant fibers are mixed into new wood materials, and then obtained by extrusion, molding, and injection molding. [0003] Compared with wood, wood-plastic composite material has a series of excellent properties, and it is also a green and renewable material, which is easy to prepare into various profiles. In recent years, it has developed rapidly internationally and is widely used in interior decora...

AI Technical Summary

Problems solved by technology

[0005] 1. Unidirectional reinforcement, single performance enhancement effect, poor interface compatibility between reinforcement fiber and wood-plastic matrix, very limited reinforcement and toughening effect, and the performance of the reinforced product cannot meet the requirements of load-bearing materials;

[0006] 2. The production process is complex, and most of them adopt multi-stage molding methods, which lead to high production costs and poor stability of material properties;

[0007] 3. When using wood-plastic products at high outdoor temperatures in summer, the thermoplastic resin will be heated and softened, making the reinforcement effect more limited under high temperature conditions
