Abstract
The invention provides a scratch-resistant light-shielding high-reflection polypropylene composite material, which comprises the following components in parts by weight: 100 parts of copolymerized polypropylene, 100 parts of ionomer, 20-50 parts of mica powder, and 20-50 parts of titanium dioxide parts, 20‑50 parts of glass microspheres. The preparation method is as follows: A. Put glass microspheres and titanium dioxide into high-speed stirring treatment; B. Mix polypropylene resin, ionomer and mica powder together at high speed; C. Add the mixed materials obtained in steps A and B to In the twin-screw extruder, the mixed material obtained in step A is added by side feeding, extruded and granulated at a temperature of 210°C-220°C and a rotational speed of 500-600r / min to obtain the composite material. The composite material has good shading effect, high reflectivity and good scratch resistance.
