AI Technical Summary
Existing PC/ABS alloy materials are difficult to balance in automotive grille applications, as they lack high gloss, excellent flame retardancy, weather resistance, and scratch resistance. Furthermore, traditional spraying processes present environmental pollution and high costs.
A high-gloss PC material that does not require spraying is prepared by melt blending a combination of polycarbonate, acrylonitrile-butadiene-styrene copolymer, compatibilizer, flame retardant, mica powder and antioxidant in a specific ratio. The compatibilizer enhances the interfacial bonding force, the flame retardant improves the fire resistance, the mica powder enhances the gloss and wear resistance, and the antioxidant improves the weather resistance.
It achieves a balance of high gloss, good flame retardancy, excellent weather resistance and wear resistance, reducing production costs and environmental pollution.
