Abstract
The present invention relates to the technical field of polymer composite materials, particularly to a low-odor polypropylene composite material and a preparation method thereof, wherein the low-odorpolypropylene composite material is prepared from the following components by weight, 55-99 wt% of polypropylene, 0.1-2 wt% of an odor adsorbent, 0.1-3 wt% of a small molecular deodorant, 0.05-0.5 wt%of a scratch-resistant agent, 0-40 wt% of talc powder, 0.1-1 wt% of a main antioxidant, 0.1-1 wt% of an auxiliary antioxidant, and 0.1-1 wt% of a lubricant. According to the present invention, with the technical scheme, the production cost is low, the market prospect is good, and the obtained low-odor polypropylene composite material can be used in the vehicle field such as vehicle instrument panels, door protection plates, sub-instrument panels and other vehicle interior and exterior decoration parts, and the household appliance field such as refrigerators and small household appliances.
Description
technical field [0001] The invention relates to the technical field of polymer composite materials, in particular to a low-odor polypropylene composite material and a preparation method thereof. Background technique [0002] There are many reasons for the odor of PP plastics, mainly including: low molecular substances remaining in PP resin; added additives migrate to the surface of the polymer or volatilize on the surface of the polymer; After the chain is oxidized, volatile substances such as aldehydes and ketones will be produced. [0003] CN1727389 relates to a polypropylene composite material with low odor and low volatile content. The odor of the material is adsorbed through fine-pore silica gel. [0004] CN1727390 relates to a low-odor polypropylene composite material and its preparation method, in particular to a product obtained by adding an odor suppressor that can effectively suppress the unpleasant smell in the polypropylene composite material. The adsorbent is ...
