Abstract

The invention relates to a wood-plastic composite, in particular to an anti-ageing wood-plastic composite board and a preparation method thereof. The anti-ageing wood-plastic composite board of the invention is manufactured by mechanically mixing and melt-mixing wood meal, calcium carbonate powder, plastic particles, maleic anhydride, stearate, pigment, antibacterial agent, antioxidant and ultraviolet absorber in sequence, and extruding and molding the mixture. The anti-ageing wood-plastic composite board has extremely wide application, is suitable for the industries of architectural decoration, transportation, furniture, municipal administration, gardens and the like, is renewable, has low cost, ageing resistance and ultraviolet resistance, is an ideal material for replacing wood, and is a novel upgraded product of the wood-plastic composite.

Description

technical field [0001] The invention relates to a wood-plastic composite material, in particular to an aging-resistant wood-plastic composite material board and a preparation method thereof. Background technique [0002] In recent years, with the enhancement of people's awareness of environmental protection, more and more people pay attention to wood-plastic composite materials that are environmentally friendly, renewable and recyclable. The application fields have involved car interior decoration substrates, building decoration, decorative materials, Outdoor tables and chairs, benches, picnic tables, packaging materials and furniture used in parks, stadiums, streets and other occasions. Wood-plastic composite material has homogeneous material, more stable size than wood, less prone to cracks, warping deformation, and no wood knots, twill and other defects; it has the processability of thermoplastics, extrusion, molding, injection molding and other processes can be used For...
