The invention discloses a bamboo and plastic
composite material and a preparation method thereof. The bamboo and plastic
composite material comprises the following raw materials according to parts by weight: 40-80 parts of modified bamboo
fiber, 15-85 parts of plastic, 2-10 parts of compatilizer, 2-10 parts of
lubricant, 0.2-1.0 part of
antioxidant, 5-15 parts of filler and 2-10 parts of
fire retardant. Bamboo raw materials are prepared into modified bamboo fibers with an explosion treatment method, wherein the modified bamboo fibers are mutually separated, and eh surface of the modified bamboo fibers is covered with
lignin; then the modified bamboo
fiber is compounded with plastic; and the product is extruded to form finished product material. According to the bamboo and plastic composite, the technical problems of poor compatibility of wood
fiber and
thermoplastic plastics can be solved to realize the purpose of comprehensively utilizing the bamboo fiber and plastic, the wood can beomitted, and the additional value of the forest residue is increased. The bamboo and plastic
composite material manufactured with the preparation method has the advantages of high
mechanical property, and strong tensile strength, bending strength and
impact strength of composite material, and the industrial production of high-performance products, such as building
engineering materials can be realized.
