Abstract

The invention relates to a production process of a fireproof environment-friendly wood-plastic floor board. The production process comprises the following steps of: crushing straws or waste wood, waste plastics and calcium carbonate filler by using a crusher, drying the powder after crushing, and then adding a lubricant, a stabilizer and a plasticizer and blending all the materials, and granulating the mixture; and furthermore, performing extrusion forming through an extruder and a die head, cooling through a cooling pool, and then cutting into desired specification. The process provided by the invention is simple, low in processing cost; and the product has the characteristics of fire protection and corrosion resistance, and has the tenacity of wood and plastics in addition to high strength. Moreover, as crop straws or waste wood and waste plastics are taken as the raw materials, recycling of resources is realized.
