Abstract

The invention discloses a modified bamboo fiber reinforced polypropylene composite material which comprises polypropylene resin, bamboo fibers, compatilizer, coupling agent, chemical modifier and the like; first, prepared natural fibers are modified and then the fibers are mixed with other components; and the mixture is extruded and formed by a double-screw extruder. According to the preparation method, the production procedures are simple and the production efficiency is improved; and the prepared modified bamboo fibers have more excellent performance, and have the advantages of environmental friendliness, sound absorption, heat insulation, low density, low shrinkage, good processing and forming performance, degradability and excellent integrated mechanical properties.

Description

technical field [0001] The invention belongs to the technical field of new materials, and in particular relates to a composite modification of natural bamboo fiber and its composite material with reinforced polypropylene and a preparation method thereof. [0002] technical background [0003] In recent years, people's awareness of environmental protection has been continuously enhanced, and the environmental pollution caused by plastics with excellent processing performance and used in various industrial products has become a common concern. In particular, fiber-reinforced composite materials are usually composed of glass fibers, carbon fibers, etc. and plastics. Waste disposal is difficult and the production environment is harsh, which adds a great burden to the environment. Therefore, the use of natural fibers as reinforcing materials to make environmentally friendly composites has attracted people's attention. The use of plant fibers and synthetic resins for composite r...
