Abstract

The invention relates to the field of wood-plastic composite materials, and provides a foamed HDPE wood-plastic profile which is prepared from the following raw materials: 20-50 parts of an HDPE matrix, 8-13 parts of POE powder, 30-60 parts of wood flour pretreated by a chitosan-nano silver composite antibacterial agent, 2-4 parts of nano calcium oxide powder with the particle size of 100-500 nm, 2-4 parts of long-chain alkyl and polyether co-modified silicone oil, 0.5-5 parts of a lubricant, 0.5-5 parts of an AC foaming agent and 0.5-0.8 part of an anti-aging agent. The invention also provides a preparation method of the foamed HDPE wood-plastic profile. The foamed HDPE wood-plastic profile has the advantages that the foamed HDPE wood-plastic profile prepared by the method is high in strength, smooth and bright in appearance, good in antibacterial property and not easy to age.

Description

technical field [0001] The invention relates to the field of wood-plastic composite materials, in particular to a foamed HDPE wood-plastic profile and a preparation method thereof. Background technique [0002] Wood-plastic composites, also known as wood-plastic composites (WPC), are an emerging class of materials that include a wide range of composite materials made from virgin or recycled plastics and natural fiber fillers . Among them, plastics can be materials such as high-density polyethylene (HDPE), polypropylene (PP), polystyrene (PS) and polyvinyl chloride (PVC), and natural fibers can include wood flour and burlap fibers. Among them, foamed wood-plastic composite materials have the functions of light weight, excellent dimensional stability, sound absorption, shock absorption, heat preservation, convenient nailing and installation, etc., and are widely used in outdoor leisure floors, wall panel decoration, fence panels and other fields. [0003] However, although f...
