Abstract

The invention discloses a degradable high-performance plant fiber filled polypropylene composite material and a preparation method thereof, and belongs to the technical field of composite polymer materials and processing thereof. The composite material is obtained by adding modified plant fibers into thermoplastic polypropylene, mixing with other components in proportion, extruding and granulating, the tensile strength of the composite material can reach 40-55MPa, the bending strength can reach 50-65MPa, the impact strength can reach 15-25KJ / m<2>, and the melt index can reach 5-15g / 10min. Themodified plant fiber and the fiber reinforced material are used together, so that the composite material has better degradability while the mechanical property is better; due to the micropore structure of the zeolite powder, the composite material can continuously absorb VOC, so that the content of the VOC is reduced; by adding a photosensitizer, part of polypropylene which is difficult to degradecan be successfully degraded, and no damage is caused to the environment; and the di-tert-butyl peroxide can improve the fluidity of the composite material in the processing process.

Description

technical field [0001] The invention relates to a polypropylene composite material and a preparation method thereof, in particular to a degradable high-performance plant fiber-filled polypropylene composite material and a preparation method thereof, belonging to the technical field of composite polymer materials and processing thereof. Background technique [0002] As the plastic industry is more and more widely used in various fields, various plastics are also seriously polluting the human ecological environment while being widely used, and then there is a demand for the development and application of degradable materials. Among them, plant fiber comes from abundant agricultural products and is cheap, making it the main material for the development of degradable materials. In recent years, composite materials using plant fibers as reinforcing materials have attracted more and more attention. However, most of the existing plant fiber composite materials have problems such as...
