Abstract

The invention discloses an ecological wood-plastic material. The ecological wood-plastic material comprises the following components in percentage by mass: 50% of polyethylene, 12.5% of straw powder,10% of aerogel powder, 10% of activated calcium carbonate, 12.5% of wood flour, 1% of stearic acid, 1% of PE wax, 2% of a calcium-zinc stabilizer and 1% of methyl acrylate. Compared with the prior art, the ecological wood-plastic material has the advantages that the defects of logs are completely overcome, the deficiencies of the logs are improved, the special wood texture of the logs is kept, a use ratio of the wood flour is greatly decreased, and the ecological wood-plastic material does not contain toxic gas of formaldehyde, methylbenzene and the like; moreover, by adding a certain percentage of the aerogel powder, the ecological wood-plastic material has excellent heat preservation and insulation performance, high hydrophobicity, very low density and good sound insulation; and meanwhile, the ecological wood-plastic material has excellent lubricating and dispersing effects, by adding the stearic acid, the PE wax regulator and the calcium-zinc stabilizer with good thermal stability performance and high environmental protection, a processing technology of the ecological wood-plastic material is greatly improved, and the product quality is further improved.

Description

technical field [0001] The invention belongs to the technical field of wood-plastic materials, and in particular relates to an ecological wood-plastic material. Background technique [0002] At present, the production technology of wood-plastic composite materials at home and abroad is constantly innovating and developing, and wood-plastic products are widely used in various industries and fields. In the case of increasingly scarce forest resources, the research and development and application of wood-plastic composite materials are in line with the basic national conditions of our country, which is conducive to promoting the conservation and sustainable development of forest resources. Low-carbon, ecological, environmental protection, and resource recycling have become the trend of the times; in addition At present, many people like to use wooden floors and wooden decorations when decorating, but some wooden materials begin to rot after three to five years, and flying insec...
