Abstract

The invention discloses a bamboo fiber / polypropylene composite material and a preparation method thereof. The method comprises the following steps of: adding polypropylene, bamboo fibers, a compatilizer and a plasticizer into a kneading machine, an internal mixer or a double-screw extruder according to a certain ratio for mixing so as to prepare the bamboo fiber / polypropylene composite material; and preparing sheets, plates, tubes or sections of the bamboo fiber / polypropylene composite material through extrusion molding, calendaring and compression molding, and other post-procedures. The sheets, plates, tubes or sections can be used for manufacturing structural, decorative, packaging products and the like. Because the bamboo fibers come from bamboo which has the advantages of rich resources, short growth cycle and natural mold and bacteria resistance, the bamboo fiber / polypropylene composite material is a novel and renewable material.

Description

technical field [0001] The invention relates to a bamboo fiber / polypropylene composite material, more specifically to a composition and preparation method of a bamboo fiber / polypropylene composite material, and belongs to the fields of polymer blending and polymer molding processing. Background technique [0002] In recent years, people try to use natural plant fibers, such as wood fibers, bamboo fibers, hemp fibers or cotton fibers, to prepare natural plant fiber-reinforced polymer matrix composites. Natural plant fiber is rich in resources and low in price; its density is lower than that of inorganic fiber, and it has less wear and tear on processing equipment; its most prominent advantage is its biodegradability and renewability. These advantages enable natural plant fiber composites to replace synthetic fiber composites to a certain extent. [0003] Wood fibers can be combined with plastics to make wood-plastic materials, which are used in construction, packaging logist...
