Composite resin composition for automotive interior materials and automotive interior material including the same

Abstract

Provided is a composite resin composition for automotive interior materials and an automotive interior material including the same. The composite resin composition comprises: 47 to 52 wt % of a polybutylene terephthalate resin; 10 to 28 wt % of a (meth)acrylate compound-conjugated diene compound-aromatic vinyl compound copolymer; 8 to 14 wt % of a polyethylene terephthalate resin; 0.1 to 2.2 wt % of a carboxy reactive epoxy resin; and 10 to 28 wt % of glass fiber containing SiO2, CaO, and Al2O3, wherein an SiO2 content is greater than a sum of a CaO content and an Al2O3 content. By changing conventional components, the composite resin composition for automotive interior materials provided herein has an effect of improving heat resistance, impact stability, and crystallization rate controllability, satisfying physical property balance between mechanical properties and fluidity, and providing excellent product reliability and appearance.
