Abstract

The invention relates to an anti-aging wood-plastic composite material board and a preparation method of the board. The preparation method comprises the steps of: firstly, evenly stirring plastic particles, diisopropylbenzene peroxide, nano-titanium dioxide, antioxidant, antioxidant synergist, light stabilizer, basic magnesium sulfate whisker, stearic acid and oxidized polyethylene; carrying out melt blending and pelleting by adopting an extruder to obtain modified plastic particles; and then stirring the modified plastic particles, wood powder and pigment, and carrying out melt blending and extruding forming by adopting the extruder to obtain the anti-aging wood-plastic composite material board. The anti-aging wood-plastic composite material board is convenient to produce and manufacture, low in cost, less in plastic consumption and wood consumption, environment-friendly and high in modulus and rigidity, does not easily cause buckling deformation, and is free from cracking and damage by worms, resistant in ultraviolet light and thermal oxidizing aging, free from color fading and decomposition and long in service life. The anti-aging wood-plastic composite material board can be used as an open-air table and chair, a stool, a picnic table, a flower box, a guardrail, a sign and the like to be widely applied to occasions such as a park, a court, municipal administration, a dock and the like.

Description

technical field [0001] The invention relates to a plastic-wood composite material, in particular to an aging-resistant plastic-wood composite material board and a preparation method thereof. Background technique [0002] Wood-plastic composite materials, also known as environmentally friendly wood, technological wood, and recycled wood, are made of resins such as polyethylene, polypropylene, and polystyrene, or recycled waste plastics and natural biological fibers such as wood powder, straw powder, and rice husk powder.
