Title:
加硫ゴムおよび熱可塑性エラストマーからなる複合成形体およびその用途
Document Type and Number:
Japanese Patent JP4615441
Kind Code:
B2
Abstract:
The object of the invention is to provide a vulcanized rubber molded product which upon melt bonding of olefinic thermoplastic elastomer thereto without an adhesive layer, can form a molded product having sufficient adhesion while generating matrix breakage upon release, as well as a molded composite comprising thermoplastic elastomer melt-bonded to the vulcanized rubber molded product. The vulcanized rubber molded product of the invention is a vulcanized rubber molded product used in melt-bonding to olefinic thermoplastic elastomer and containing 2 to 10 wt % olefinic resin having a crystallinity of 10% or more as determined by a differential scanning calorimeter (DSC). The molded composite of the invention is a molded composite comprising (1) a vulcanized rubber molded product containing 2 to 10 wt % olefinic resin having a crystallinity of 10% or more as determined by a differential scanning calorimeter (DSC) joined to (2) a molded product consisting of a thermoplastic elastomer containing 10 wt % or more olefinic resin having a crystallinity of 10% or more, as determined by a differential scanning calorimeter (DSC), and having a gel fraction of 30 wt % or less. The molded composite is used preferably in an interior or exterior decorative material for an automobile, particularly in a weather strip.
