The invention relates to a
thermoplastic elastomer composition with low TVOC and low
Fogging for automotive trim and a preparation method of the
thermoplastic elastomer composition. The
thermoplastic elastomer composition is prepared from the following raw materials with the following content in percentage by weight: 30-40% of
styrene-
ethylene-butylene-
styrene block copolymers, 5-15% of naphthenic oil, 35-45% of
alkene block copolymers, 5-15% of homopolymerized
polypropylene and 0.1-0.2% of an
antioxidant. The
thermoplastic elastomer composition disclosed by the invention has the advantages that Infuse 9807 and SEBS are added for compounding, the Infuse 9807 novel
alkene block copolymers (OBC) enable the high-low temperature compression and the deformation without separation of the excellent properties of elastomers after modification by polyblending to be improved, the Infuse 9807 novel
alkene block copolymers and PP are in stable secondary injection molding and bonding or direct injection molding, when the
thermoplastic elastomer composition is used as components of the automotive trim, the
thermoplastic elastomer composition can be used for a long time, separation cannot be generated, the thermoplastic elastomer composition is a non-toxic harmless environment-friendly material for human bodies and environment, the thermoplastic elastomer composition completely passes the inspection according to the standard of 'Air Qualitative Assessment Guide in Passenger Vehicle' (GB / These 7630-2011) and meet the using requirements of automotive trim workpieces.
