Abstract

The invention discloses a rare earth-modified natural fiber-reinforced polypropylene composite material and a preparation method thereof. The rare earth-modified natural fiber-reinforced polypropylene composite material comprises, by weight, 80-100 parts of polypropylene, 30-60 parts of natural fibers, 5-8 parts of a compatilizer, 20-35 parts of a fire retardant, 0.5-1.0 parts of a compound anti-oxidant and 1-1.5 parts of a processing assistant, and before use, the natural fibers are modified by a rare earth modifier. The preparation method has simple processes, a low cost and no pollution on the environment. The rare earth-modified natural fiber-reinforced polypropylene composite material has excellent mechanical properties, fire resistance and aging resistance, is environmentally friendly, can be recovered, can be widely used in fields of delivery vehicles such as automobiles, light rail trains and high-speed rail trains and in industries of buildings and office furniture.

Description

technical field [0001] The invention belongs to the technical field of modification and processing of polymer composite materials, and in particular relates to a rare earth modified natural fiber reinforced polypropylene composite material and a preparation method thereof. Background technique [0002] Polypropylene (PP) material has the advantages of low density, good rigidity, high strength, warpage resistance and good chemical resistance, but it also has poor impact resistance (the notched impact strength at room temperature is only 4-6kJ / m 2 ), easy aging, easy thermal deformation, large molding shrinkage and other shortcomings, which limit its application in various fields. The method of adding reinforcing fibers is usually used to improve its comprehensive performance and meet the requirements of various application fields. [0003] In recent years, with the increasing shortage of energy, rising energy prices and increasing pressure on environmental protection, govern...
