Abstract

The invention discloses a high-performance wood-plastic plate. The high-performance wood-plastic plate is prepared from the following raw materials in parts by weight: 23-34 parts of polyvinyl chloride, 20-30 parts of plant straws, 8-17 parts of calcium carbonate, 15-25 parts of modified attapulgite clay, 9-14 parts of polyolefin resin, 6-13 parts of ceramic fiber, 3-5 parts of carbon black, 1-2 parts of calcium stearate, 2-3 parts of a flexibilizer, 2-4 parts of a coupling agent, 1-3 parts of a stabilizer and 1-2 parts of an antioxidant. The high-performance wood-plastic plate is simple in preparation method, low in cost, high in abrasion resistance, excellent in heat preservation performance and excellent in moisture resistance.

Description

technical field [0001] The invention belongs to the technical field of wood-plastic boards, and in particular relates to a high-performance wood-plastic board and a preparation method thereof. Background technique [0002] At present, PVC wood-plastic panels occupy an important position in the field of furniture and floor decoration due to their excellent performance. With the acceleration of my country's economic construction, the scope of PVC wood-plastic panels is becoming more and more extensive. In the process, it is usually necessary to place various main and auxiliary materials in a high-temperature mixing chamber, mix them in a molten state, and then cool the high-temperature mixed materials before extruding them through the extruder die. Existing PVC wood-plastic panels still have certain defects during use, and there is a large room for improvement in terms of moisture resistance, heat preservation, and wear resistance. Contents of the invention [0003] The pres...
