Abstract

The invention discloses an improved polypropylene composite material and a preparation method thereof. The method comprises the following steps: mixing attapulgite and nano titanium dioxide, adding absolute ethyl alcohol and a solubilizer, and performing the ultrasonic dispersion, thus obtaining ultrasonic dispersion; adding the ultrasonic dispersion into polypropylene, mixing, extruding, granulating, and drying, thus obtaining the improved polypropylene composite material. The attapulgite and the nano titanium dioxide are mixed, then the absolute ethyl alcohol and the solubilizer are added and ultrasonically dispersed, and the ultrasonic dispersion can effectively modify the polypropylene, so that while the ultraviolet aging resistance of the polypropylene composite material is improved,the original mechanical performance of the polypropylene can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of polypropylene composite materials, and in particular relates to a modified propylene composite material and a preparation method thereof. Background technique [0002] Polypropylene (PP) has good mechanical properties and processing properties, a simple synthesis method, abundant raw material sources, low price, and a wide range of applications. However, due to the presence of tertiary carbon atoms with high chemical activity, polypropylene materials are prone to aging under ultraviolet light, resulting in performance degradation. Therefore, polypropylene needs to be modified to make up for its lack of UV aging resistance. [0003] At present, the anti-ultraviolet aging performance of polypropylene materials is improved by adding montmorillonite, but the added amount has a great influence on the mechanical properties of polypropylene materials. When the content of montmorillonite is very small, the modulu...
