The invention relates to a bamboo powder - high-density polyethylene composite and its process for preparing, which consists of granulating in the twin-screw extruder after kneading the raw material components comprising bamboo powder, high-density polyvinyl resin, polyethylene oxide and geoceric acid, then obtaining the product by squeezing the master batch in the single screw extractor. The external appearance of the invented bamboo powder - high-density polyethylene composite is close to the wood, and the invented product has good fire-retardancy. By changing different dies, complex-shaped products can be prepared and is capable of boring, digging and nailing. The product of this invention is of no release of formaldehyde, of nice appearance, good handle, no warp, excellent resistance to aging, and so it has a prodigious superiority outside, for example, it can be used as marine landscape materials such as corridor, sunshade, baluster and movable dwelling. |
