AI Technical Summary
Existing automotive mudguards are prone to localized material cracking, increased noise, and mud accumulation due to gravel impact and mud adhesion under high-speed driving or harsh road conditions, affecting vehicle driving comfort and component durability. Existing improvement methods cannot simultaneously achieve multiple properties such as lightweight, stone impact resistance, low-temperature toughness, and mud adhesion resistance.
Using polypropylene as the matrix, modified hollow glass microspheres and modified basalt fibers are prepared through co-precipitation reaction and surface modification treatment to enhance the impact resistance and anti-adhesion ability of the material. The interfacial bonding strength is improved by grafting polyolefin elastomer and maleic anhydride onto polypropylene, and the material properties are improved by combining nano-silica, carbon black and lubricant.
It achieves lightweight, low-temperature impact resistance, stone chip resistance, and mud and water adhesion resistance in automotive mudguards, reduces mud residue, and improves the long-term durability and noise reduction effect of the material.
