Problems solved by technology

[0004] In view of this, it is necessary for the present invention to provide a TPV composition and a preparation method thereof. With PP and EPDM as the base, a plasticizer and a crosslinking agent are added therein, and other auxiliary agents are used to obtain a TPV composition with high packaging Adhesive bonding strength, which solves the degumming problem caused by the insufficient bonding strength of the existing TPV and ABS coating

Abstract

The invention discloses a TPV composition and a preparation method thereof. The material is prepared from 30-40 parts of polypropylene, 20-30 parts of ethylene propylene diene monomer, 20-30 parts ofa plasticizer, 10-20 parts of a filler, 0.2-1 part of a lubricant, 0.2-1 part of a crosslinking agent, 0.5-2 parts of an assistant crosslinking agent, 0.3-0.5 part of an antioxidant and 1-5 parts of aporous adsorbent. According to the invention, the special auxiliary agent is added into the formula, so that the prepared TPV composition has high encapsulation bonding strength.

Description

technical field [0001] The invention belongs to polymer materials, and in particular relates 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. The surface of its parts has high gloss and can be used for high-gloss black appearance parts. However, in some products, secondary injection soft rubber molding is required to improve the soft touch and anti-slip effect of the product, such as the application in the base of the camera. [0003] Due to the characteristics of vulcanized rubber, TPV has a touch similar to 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, and it is difficult to form a good surface bonding effect with ABS. For example, in the Ch...
