Abstract

The invention provides a low emission polypropylene composite material with low odor. The composite material is prepared from following raw materials in parts by weight: 49.6 to 97.6 parts of polypropylene, 0 to 40 parts of talcum powder, 0.4 to 4 parts of antioxidant, 1 to 5 parts of first deodorant, and 1 to 5 parts of second deodorant. The first deodorant is an extraction type deodorant with aneffective component content of 40-85%. The second deodorant is an adsorption type deodorant with a loaded special substance. The invention also provides a preparation method of the polypropylene composite material. The preparation technology is simple, the cost is low, and moreover, the material has excellent mechanical properties, low odor, and low emission.

Description

technical field [0001] The invention belongs to the field of polymer materials, and relates to a polypropylene composite material, in particular to a low-odor and low-emission polypropylene composite material and a preparation method thereof. Background technique [0002] Under the trend of "replacing steel with plastic", polypropylene can fully meet the material performance requirements of automotive interior parts through toughening, strengthening and other modifications. Nowadays, modified polypropylene materials are widely used in automotive interiors, mainly used in instrument panels, door guards, sub-dashboards, pillar guards and other components. [0003] However, as the amount of polymer materials used in auto parts continues to increase, some problems have also been discovered. The most important thing is the increase in plastic parts, which causes air pollution problems such as irritating odors in the car. The sporadic nature of the interior parts of the car not o...
