Abstract

The invention discloses a method for fiber-reinforced modified wood-plastic decorative plates, the method comprises the following steps: dispersing a silane coupling agent in an ethanol solution, soaking aramid fiber therein, washing with deionized water, and drying in an oven to obtain silane coupling agent modified ammonium polyphosphate; adding organically modified zirconium phosphate and n-butylamine into deionized water, oscillating in a water bath, adding carboxymethyl chitosan, stirring at constant temperature under microwave, washing with deionized water and ethanol, centrifuging, anddrying under vacuum to obtain modified zirconium phosphate; drying regenerated high density polyethylene, putting into a mixer for mixing and melting, adding an antioxidant, silane coupling agent modified ammonium polyphosphate, the silane coupling agent modified ammonium polyphosphate and the modified zirconium phosphate, finally adding modified wood flour for uniform mixing, paving in a mold, putting into a hot press for preheating, starting hot pressing, and then putting into a cold press for cold pressing to prepare the wood- plastic decorative plate.

Description

technical field [0001] The invention belongs to the field of plastic product processing, and in particular relates to a method for fiber-reinforced modified wood-plastic decorative boards. Background technique [0002] Due to the lack of forest resources in our country, the ineffective use of windproof and sand-fixing shrubs, and the serious pollution of waste plastics, it is urged to use the organic combination of wood flour and plastics to prepare wood-plastic composite materials. Wood-plastic composite materials are due to their excellent moisture resistance, decay resistance, With unique appearance, environmental friendliness and recyclability, it is widely used in construction, outdoor decoration, transportation and other fields. [0003] However, wood-plastic composites have problems such as low strength, poor toughness, and creep. The commonly used methods for wood-plastic reinforcement and toughening mainly include modifying the plastic matrix, adding reinforcements,...
