Abstract

The invention discloses a TPV easy to bond with glue and a manufacturing method thereof. The TPV is prepared from EPDM, PP, maleic anhydride grafted PP, EMMA, naphthenic oil, calcium carbonate, peroxide, a cross-linking agent, a cross-linking auxiliary agent and an antioxidant through two-step twin-screw granulation, the problem that TPV is difficult to adhere to glue is solved, meanwhile, a lubricating agent is not added, the naphthenic oil is used for further improving the bonding effect, the problem that TPV is difficult to adhere to glue is thoroughly solved, and the product can be bondedto metal through common glue, does not need special treatment and is convenient and fast to use.

Description

Technical field: [0001] The invention relates to the technical field of thermoplastic elastomers, in particular to a TPV easily bonded with glue and a manufacturing method thereof. Background technique: [0002] TPV thermoplastic elastomer, that is, thermoplastic dynamic vulcanizate. It is a thermoplastic elastomer produced by dynamic vulcanization of EPDM (ethylene propylene diene monomer) and PP (polypropylene) through a twin-screw extruder. It has excellent processing performance and aging resistance, good elasticity, and is regarded as an alternative New material for PVC and conventional vulcanized EPDM. TPV materials are currently widely used in various fields such as automobile sealing strips, building sealing strips, wires and cables, daily necessities, etc., and have broad market prospects. The main raw materials of TPV include EPDM, PP, filler and rubber oil and various additives. [0003] Because TPV has a wide range of applications, it is often necessary to use...
