Abstract

The invention provides a degradable flame-retardant wood-plastic composite and a preparation method thereof. The wood-plastic composite material is prepared from the components of waste polypropylene, waste low-density polyethylene, nanometer kaolin, polyhydroxybutyrate, poly(ethylene naphthalate), modified berberis amurensis powder, shell powder, glass fiber, quartz fiber, bronyl acetate, itaconic acid, disodium maleate, ethylene bisstearamide, composite flame retardant, coupling agent and stabilizer. The degradable flame-retardant wood-plastic composite material is degradable, impact strength of the composite material is up to 9.3-10.7kJ / m<2>, the tensile strength is up to 43-55MPa, the flame retardant rating is up to grade UL-94 V0, the formaldehyde release amount is 0.036-0.071mg / L, and the standard of less than 1mg / L of formaldehyde release amount of materials used in interior architecture environments is met.

Description

technical field [0001] The invention belongs to the field of composite materials, and in particular relates to a degradable flame-retardant wood-plastic composite material and a preparation method thereof. Background technique [0002] Wood-plastic composite material is a new type of green environmental protection material. Wood-plastic composite material refers to the use of polyethylene, polypropylene and polyvinyl chloride instead of the usual resin adhesive, and more than 50% of wood powder, rice husk, straw, etc. Waste plant fibers are mixed into new wood materials, and then processed by extrusion, molding, injection molding and other plastic processing techniques, mainly used in building materials, furniture, logistics packaging and other industries. [0003] Although wood-plastic composite materials are green and environmentally friendly, they can "turn waste into treasure", which not only retains the advantages of wood in terms of processing performance, but also ove...
