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

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...
