Abstract

The invention discloses an environment-friendly PVC (polyvinyl chloride) wood-plastic foamed board material and a preparation method thereof, and relates to the technical field of a PVC wood-plastic material. The foamed board material is prepared from the following raw materials: polyvinyl chloride, modified rice husk powder, modified saw dust, kaolin, pyrophyllite powder, light calcium carbonate,styrene-acrylic emulsion, benzoyl peroxide, polybutanediol carbonate, a foaming agent, a processing modifier ACR, an adhesion aid and an initiator. The preparation method comprises the steps of mixing the raw materials, extruding and shaping. The PVC wood-plastic foamed board material has an integrated and beautiful appearance, high dimensional stability, light weight and high strength, has the advantages of high sound-insulating and heat-insulating properties, high flame-retardant and waterproof grade, excellent mildewproof and insect-preventing properties and the like, and is long in service life, wide in application field, environment-friendly and suitable for popularization and application.

Description

technical field [0001] The invention relates to the technical field of PVC wood-plastic materials, in particular to an environment-friendly PVC 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 and uneven bubbles in the production of flooring, which not only affects the appearance and sales of the product, but also affects the sound insulation and heat insulation of the finished wood-plastic board, flame retardant and waterproof. , anti-mildew and anti-insect pr...
