Abstract

The invention discloses a lightweight wood plastic foam board and a preparation method thereof and relates to the technical field of wood plastic board manufacturing. The foam board is prepared from the following raw materials: PVC resin, terpene resin, methyl acrylate, modified ramie fibers, corn straw powder, barium feldspar powder, faujasite powder, methylpentachlorostearate, oxidized polyethlene wax, azo-bis-iso-heptonitrile, N-hydroxymethyl acrylamide, a calcium-zinc stabilizer, a foaming agent, a foam stabilizer, a coupling agent and a flame retardant. The preparation method of the lightweight wood plastic foam board is characterized in that the lightweight wood plastic foam board is prepared by mixing and extruding the raw materials. The wood plastic foam board disclosed by the invention has the characteristics of simple and convenient preparation, stable mechanical property, high yield strength, good toughness, heat insulation, flame retardance, water resistance and impermeability.

Description

technical field [0001] The invention relates to the technical field of wood-plastic board manufacture, in particular to a lightweight wood-plastic foam board and a preparation method thereof. Background technique [0002] Wood-plastic board is a new type of environmentally friendly wood-plastic composite material product. The wood powder produced during the production of medium and high-density fiberboards is added to recycled plastics to make wood-plastic composite materials through granulation equipment, and then extruded into production groups. Made into wood-plastic flooring. The PVC foamed wood-plastic material prepared by the current process formula is prone to problems such as delamination, uneven bubbles, and poor mechanical properties when producing floors, which not only affects the appearance and sales of the product, but also greatly reduces the practical performance of the finished wood-plastic board. , therefore, needs to be improved.
