Title:
ISOTROPIC ELECTROMAGNETIC SHIELDING POLYPROPYLENE COMPOSITE MATERIAL, PREPARATION THEREFOR, AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/061004
Kind Code:
A1
Abstract:
The present invention relates to an isotropic electromagnetic shielding polypropylene composite material, a preparation therefor, and use thereof. The isotropic electromagnetic shielding polypropylene composite material comprises polypropylene, polyethylene, conductive carbon black, a lubricant, an antioxidant, and a filler. The polypropylene composite material of the present invention has a relatively good electromagnetic shielding effect (more than 30 dB), and also achieves an isotropic electromagnetic shielding effect.
