Abstract

The invention discloses a TPV composition and a preparation method thereof, which consists of 30-40 parts of polypropylene, 20-30 parts of EPDM rubber, 20-30 parts of plasticizer, 10-20 parts of filler, lubricating 0.2-1 part of agent, 0.2-1 part of cross-linking agent, 0.5-2 part of auxiliary cross-linking agent, 0.3-0.5 part of antioxidant and 1-5 parts of porous adsorbent. In the present invention, special additives are added to the formulation, so that the prepared TPV composition has high encapsulation bonding strength.

Description

technical field [0001] The invention belongs to polymer materials, in particular to a TPV composition and a preparation method thereof. Background technique [0002] ABS (acrylonitrile-butadiene-styrene terpolymer) resin is a thermoplastic material with high rigidity and high toughness. Its surface has high gloss and can be used for high-gloss black appearance parts. However, in some products, it is necessary to use secondary injection of soft rubber to improve the soft touch and anti-slip effect of the product, such as the application in the camera base. [0003] Due to the characteristics of vulcanized rubber, TPV has a touch similar to that of human skin, and is widely used in various fields. However, the basic materials of TPV are PP and EPDM, both of which are non-polar materials. The commonly used plasticizers are also non-polar paraffin oil or naphthenic oil, which is difficult to form a good surface bonding effect with ABS. For example, in Chinese patent CN10349742...
