Abstract

The invention belongs to the technical field of electric conduction composites, and particularly relates to a cassava residue / PP two-phase electric conduction composite and a preparation method thereof. The cassava residue / PP two-phase electric conduction composite is characterized by being prepared from, by weight, 10-20 parts of electric conduction filler, 10-20 parts of cassava residues and 60-80 parts of PP. The cassava residue / PP two-phase electric conduction composite has the advantages of being small in weight, easy to machine, resistant to wear and corrosion and adjustable in electrical resistivity within a large area. According to the method, through the effect of mechanical ball milling, the electric conduction filler can be well dispersed in cassava residues and a PP base body, the electric conduction percolation threshold value is low, the process is simple, and the cassava residue / PP two-phase electric conduction composite and the preparation method are green and environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of conductive composite materials, and in particular relates to a cassava residue / PP two-phase conductive composite material and a preparation method thereof. Background technique [0002] Originally produced in the Amazon River Basin, cassava is one of the three largest tuber crops in the world and is widely planted in most parts of the country. my country's cassava industry has already achieved large-scale production, and its processing technology is mature. It is one of the main economic crops for starch production. As one of the main cassava planting areas in Guangxi, a large amount of cassava is planted in the whole region every year. Cassava in Guangxi is mainly used to produce cassava starch, however, a large amount of cassava residue waste will be produced during the production and processing process. Cassava residue mainly contains a small amount of starch and fiber, and the main fiber components ...
