Squeak reduction thermoplastic resin composition and creaking sound reduction structure

摘要

Provided is a thermoplastic resin composition (X) for squeaking noise reduction containing a rubber-reinforced vinyl-based resin (A) obtained by polymerizing a vinyl-based monomer (b1) in the presence of an ethylene/α-olefin-based rubber polymer (a1) having a melting point (Tm) of 0°C or higher, the thermoplastic resin composition being characterized in that the amount of silicon contained in the thermoplastic resin composition (X) is 0.15 mass% or less relative to the 100 mass% of the thermoplastic resin composition (X). According to the present invention, it is possible to provide a structure whereby the squeaking noise generated when components grind against each other is markedly reduced and whereby the squeaking noise reduction effect is maintained even when the structure is placed under a high temperature for a long period of time, and which offers excellent impact resistance and molded outer appearance.
