Problems solved by technology

However, its application range is only for customized materials, and it cannot be added to other products to reduce odor. At the same time, it cannot avoid the odor problem caused by the volatilization of toxic substances released due to high temperature and high shear during the secondary injection molding process.

Abstract

The invention discloses a polypropylene odor adsorption masterbatch for automobiles, which comprises the following ingredients in parts by weight: 30-80 parts of polypropylene, 20-60 parts of a porous adsorbent, and the porous adsorbent is diatomite with a porous structure or its derivatives. In the present invention, by compounding and modifying polypropylene and a specific porous adsorbent, the obtained polypropylene odor-absorbing masterbatch has better odor-adsorbing characteristics, and can be widely used in the extrusion or injection molding process of automobile polypropylene products , and can be applied to different processing techniques, effectively adsorb toxic small molecular substances in the production process, and form an irreversible physical and chemical reaction, avoid later volatilization, thereby improving the odor effect of the product. At the same time, the invention also discloses a preparation method of the polypropylene odor-absorbing masterbatch for automobiles.

Description

technical field [0001] The invention relates to a polypropylene odor absorption masterbatch and a preparation method thereof, in particular to a polypropylene odor absorption masterbatch for automobiles and a preparation method thereof. Background technique [0002] In recent years, pollution incidents in various types of automobiles have occurred frequently, and consumers have increasingly strong demands for health in the car. The air pollution problem inside the car has become the third largest indoor environmental pollution problem that endangers human health after China's decoration and furniture pollution, and PM2.5 pollution in the indoor environment. Generally speaking, the air quality problem in the car is mainly caused by the toxic substances released by the interior materials of the car, emitting an unpleasant smell, which is directly related to the vehicle manufacturing process and parts, and has a relatively large impact on the car dashboard assembly, Door trim,...
