Abstract

The present invention relates to a highly rigid composite resin composition with excellent tactility. Specifically, the composite resin composition according to the embodiment of the present inventionis excellent in tactility and heat resistance as well as excellent in rigidity and scratch resistance as it comprises a polyamide resin as a component thereof. Thus, a molded article prepared therefrom can be advantageously used as automobile interior and exterior parts, electronic and household appliances parts, construction and industrial supplies, and the like.

Description

technical field [0001] The present invention relates to a highly rigid composite resin composition having excellent touch and heat resistance. In particular, the present invention relates to a composite resin composition having not only excellent touch and heat resistance but also excellent rigidity by including polyamide as a resin component. Background technique [0002] Polypropylene resin is a general-purpose resin widely used as automotive interior and exterior parts, components of electrical and home appliances, construction and industrial materials, etc., due to its excellent economical efficiency, mechanical properties, formability, and chemical resistance. s material. In order to improve the feel of molded articles molded and produced from such polypropylene resins, attempts have been made to provide composite resins containing polypropylene resins and thermoplastic elastomers. However, the tactile feeling of this composite resin has been improved, but there are s...
