Embodiment Construction

[0021] The first embodiment

[0022] First select 40 (weight) parts of waste plastic, 50 (weight) parts of plant fiber, 15 (weight) parts of calcium carbonate, and 5 (weight) parts of polyethylene wax. Among them, the plant fiber is rice straw fiber, wheat straw fiber, corn straw fiber, sorghum straw fiber, cotton straw fiber, soybean straw fiber, reed fiber, sugarcane fiber, weed fiber, bamboo fiber, banana straw fiber and Any one, any two or a mixture of two or more of the coconut husk fibers. In this embodiment, corn stover fiber is used.

[0023] Then put waste plastic, calcium carbonate, polyethylene wax and the above-mentioned plant fiber into the extruder together, after plasticizing, uniformly mixing, and extruding into pellets.

[0024] Then, a large hydraulic press is used for compression molding to make a composite board.

[0025] The plant fiber is made by crushing other plants or plant straws except wood. The corn fiber used in this embodiment is made by crushing corn...

Abstract

The present invention discloses one kind of composite board and its making process. The composite board is made with waste plastic, plant fiber, calcium carbonate, polyethylene wax and other material, and through plasticizing, mixing and extruding in a plastic extruding machine, and pressure forming in a large hydraulic press. It has low production cost, environment friendship, high moisture resistance and high fire-proofing performance, and may be applied in furniture, packing box, building shuttering, indoor decorating, etc.

Description

Technical field [0001] The invention relates to a composite board and a preparation method thereof. Specifically, it is a composite board used as a furniture board, a packaging box board, a building template or an interior decoration board, and a preparation method thereof. Background technique [0002] At present, the composite boards used as furniture boards, packaging box boards, building templates or interior decoration boards include wood chipboards, wooden multilayer boards and medium-density boards. These wood chipboards, wooden multi-layer boards and MDF are all made of wood chips or wood boards as the main raw materials, and then mixed with glue, which is mixed and molded. Because this composite board uses wood chips or planks as the main raw material, a large amount of wood is required, which not only has a high production cost, but also damages the ecological environment due to felling of wood. In addition, since the production of this composite board requires glue, an...
