Abstract

The present invention relates to a low-odor TPV for vehicle air conditioner pipe members, wherein the low-odor TPV is prepared from a vulcanized mixture through a dynamic vulcanization process, and the vulcanized mixture comprises, by weight, 100 parts of a vulcanizable elastomer, 50-200 parts of a thermoplastic polyolefin, 0.01-10 parts of a cross-linking agent, 10-100 parts of filling oil, 0.1-5 parts of an olefinic acid compound-modified thermoplastic polyolefin, and 0.01-0.1 part of a carbodiimide compound. The TPV of the present invention meets the requirements of the national vehicle interior air-related standards.

Description

technical field [0001] The invention relates to the field of low-odor thermoplastic vulcanizate (TPV), and also relates to the TPV applied to automobile air-conditioning pipe fittings. Background technique [0002] At present, a class of polyolefin thermoplastic elastomers (TPOs) is prepared by blending a semi-crystalline plastic (such as PP) with an amorphous rubber (such as EPDM) using rubber-plastic blending technology, creating a new class of The first of its kind in thermoplastic elastomers. Although such thermoplastic elastomers have obtained the physical properties and processing properties of elastomers and thermoplastics, their mechanical properties are not satisfactory, so they have not been widely used. [0003] For this reason, the development of these blending technologies in recent years has mainly focused on dynamic vulcanization. Dynamic vulcanization is the process of elastic vulcanization and crosslinking at the same time of melting and mixing under high ...
