Abstract

The invention relates to a TPV thermoplastic elastomer with an excellent adhesive property and a preparation method thereof. The TPV thermoplastic elastomer comprises the following raw materials in parts by weight: 15-30 parts of EPDM, 10-20 parts of PP, 10-20 parts of SEBS, 1-5 parts of EVA, 1-5 parts of TPU, 1-5 parts of C5 petroleum resin, 1-5 parts of terpene resin, 10-30 parts of softening oil, 15-20 parts of ABS resin, 1-3 parts of MBS resin, 1-3 parts of PA, 3-5 parts of a vulcanizing agent, 1-2 parts of antioxidant and 1-2 parts of an anti-aging agent. The TPV thermoplastic elastomer provided by the invention is prepared in the manner of twice extruding pelletizing through a twin screw parallel mixing type extruder; the invention mainly solves the problem of poor adhesive propertyof the TPV thermoplastic elastomer with other materials; processing property and abrasion resistance of the TPV thermoplastic elastomer are both greatly promoted, so that the TPV thermoplastic elastomer can be applied to the fields of home appliances, automobiles, recreation and sports, medical treatment, and the like, and especially can be applied to automotive trim leather.

Description

technical field [0001] The invention belongs to the technical field of TPV thermoplastic elastomer modification, in particular to a TPV thermoplastic elastomer with good bonding performance and a preparation method thereof. Background technique [0002] TPV is the abbreviation of Thermoplastic Vulcanizate. The Chinese name is thermoplastic EPDM dynamic vulcanized elastomer or thermoplastic EPDM dynamic vulcanized rubber. It is a highly vulcanized EPDM particle dispersed in continuous polypropylene PP phase. Molecular elastomer materials. The physical properties and functions of TPV at room temperature are similar to those of thermosetting rubber. At high temperatures, they behave like thermoplastics, and can be processed quickly, economically and conveniently. [0003] TPV has excellent performance. It has good elasticity and compression deformation resistance, and has outstanding environmental resistance, aging resistance, oil resistance, and solvent resistance. It has a w...
