Process for preparing composite material consisting of a vulcanized elastomer associated with a thermoplastic elastomer with polyamide blocks and composite so formed.

摘要

The invention relates to a process of preparation of material compound formed by a vulcanized elastomer containing FUNCTIONS carboxylic acid or anhydride dicarboxylic acid, coupled with an elastomer thermoplastic polyamide blocks, wherein A elastomeric composition comprising ELASTOMER vulcanizable a crosslinking system and optionally various adjuvants it is vulcanized in a mold part of which is occupied by said thermoplastic elastomer SEQUENCE polyamides being comprised the vulcanization temperature -15 (degrees) CY + 5 (DEGREES) C with respect to the Vicat point OF SEQUENCE said thermoplastic elastomer polyamides, ELASTOMERIC COMPOSITION AND kINETIC vulcanizing being such that the material exhibits cohesive failure DURING AN EFFORT IN THE SEPARATION OF THE TWO ELASTOMEROS. This process leads to material compounds having excellent properties, particularly TENSILE STRENGTH (RUPTURA Cohesive). The invention also relates to the composite material thus constituted and its application in sporting goods PERFORMED BY THESE MATERIALS.
