Abstract

A method for preparing plastic wood slab includes applying 30-90 shares of crops fiber, 10-70 shares of regenerated plastic, 1-10 shares of wetting agent, 1-10 shares of coupling agent, 10-20 shares of fire retardant, appropriate amount of absorber and appropriate amount of antiager as raw materials, mixing them then pressing them to be slab. The prepared slab is on specification as width of 500-2000mm and length of 2000-4000mm.

Description

technical field [0001] The invention relates to a plastic wood board and a preparation method thereof. Background technique [0002] Wooden materials, steel, cement, and plastics are called the four basic raw materials, and woody materials are the only renewable ones. At present, the amount of large-diameter timber in my country is very small, which cannot meet the needs of the market. In order to solve this crisis, people advocate replacing wood with steel and plastic, and consume non-renewable petroleum and iron ore resources. , but led to the occurrence of one raw material crisis after another. On the other hand, facing the number of big trees, people use composite methods to glue small materials together. For this reason, a large amount of rubber must be used, of which 90% More than % is urea-formaldehyde glue, which is the main source of formaldehyde pollution in the air. [0003] Now the annual output of plastics in the world is about 130 million tons, and the output i...
