Embodiment 1～4

[0029] In Examples 1 to 4, the olefin block copolymer is produced by U.S. Dow Chemical Company under the trade name of Infuse9807; The styrene-ethylene-butylene-styrene block copolymer; the homopolypropylene is the homopolymer PP produced by SK Petrochemical Company in South Korea, and the product name is PP R370Y; the naphthenic oil is the naphthenic oil produced in Karamay, Xinjiang, and the commodity The name is KN4010; the antioxidant is a hindered phenolic antioxidant, specifically AO 1010 from Ciba.

[0030] Its preparation method is as follows:

[0031] (1) take raw materials by each component shown in Table 1 and the weight percentage content thereof;

[0032] (2) Mix SEBS and naphthenic oil (plasticizer) in the above raw materials in a high mixer for 20 to 30 minutes;

[0033] (3) Add other raw materials and mix evenly, take out;

[0034] (4) Then put it into a twin-screw machine to extrude and granulate, the host speed of the screw is 200-300 rpm, and the processi...

Abstract

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.

Description

technical field [0001] The invention relates to a thermoplastic elastomer material and a preparation method for low TVOC and low Fogging used in automotive interiors, in particular to a thermoplastic elastomer that has passed the standard detection of the "Guidelines for the Evaluation of Air Quality in Passenger Cars" (GB / T 27630-2011) Elastomeric composition and method for its preparation. Background technique [0002] Elastomers have good weather resistance, heat resistance, compression deformation resistance, matte non-glare and excellent anti-skid performance. When in contact with hard objects such as metal glass, they can reduce vibration and noise, and are widely used in automobiles. Interior accessories (such as coasters, sliding curtains, storage boxes, gear handles, etc.). [0003] As we all know, automotive interior parts (such as coasters, sliding curtains, storage boxes, gear handles, etc.) are generally made of a layer of elastomer coated with a secondary inje...
