Problems solved by technology

For example, because activated carbon itself is black in color, it can only be used in black materials, so its use is greatly limited. In addition, it is only simple physical adsorption, and odor molecules will still be released when heated. Therefore, using activated carbon for The method of physical adsorption has many shortcomings

Abstract

The invention relates to a low-smell polypropylene composite material and a preparation method thereof. The low-smell polypropylene composite material comprises the following components in percentage by weight: 54 to 90 percent of polypropylene, 10 to 40 percent of talcpowder, 0.5 to 5 percent of plant fibers and 0.1 to 1.0 percent of heat stabilizer disteaxyl thiodipropionate (DSTP). The preparation method comprises the following steps of: weighing the raw materials in a weight ratio; performing dry mixing in a high-speed mixer for 3 to 5 minutes; and putting the mixed raw materials into a twin-screw machine, and melting, extruding and granulating to prepare granules of the polypropylene composite material. The polypropylene composite material has a simple preparation process, is low in cost, good in smell, low in organic volatile matter content and high in other fundamental characteristics such as mechanical properties and thermal oxidization stability.
