Abstract

The invention relates to a PVC wood-plastic low-foaming particle material which has the characteristics of light mass, high specific strength, water resistance, corrosion resistance and heat insulation and the characteristics of nailing, sawing and planing processing of wood. The PVC wood-plastic low-foaming particle material has very high weatherability and can be widely used for outdoors productmarkets such as exterior decoration of buildings, garden landscape, fences and walkways. The PVC wood-plastic low-foaming particle material has the significant characteristics of low formula cost andlow material density; and the comprehensive manufacturing cost of a product can be greatly lowered.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a PVC wood-plastic low-foaming granular material. Background technique [0002] PVC wood-plastic composite material is a new type of composite material that has been booming at home and abroad in recent years. It refers to the use of polyvinyl chloride, mixed with bamboo powder, rice husk, bamboo powder and other plant fibers to form new wood materials, and is prepared by mixing and granulating. composite particles. After extrusion, molding, injection molding and other plastic processing techniques, the plates or profiles are produced. PVC wood-plastic foaming materials are used as interior decoration materials, which have high requirements for flame retardancy and smoke suppression, in order to avoid fires, or minimize the personal and property losses caused by fire emergencies. At present, the main disadvantages of plastic wood products used outdoors are: easy to f...
