Abstract

The invention provides a TPO automotive interior material of a graphene reinforced EPDM rubber and a preparation method and application thereof. The TPO automotive interior material sequentially includes a TPO skin layer, a foam layer and a back coat layer in order from bottom to top. The preparation method comprises the steps of: preparing a graphene-containing EPDM masterbatch by a twin-screw extrusion method, and mixing a TPO component, a graphene reinforced EPDM rubber component, a polyolefin elastomer component, a polypropylene component and a pigment component through a metering device to prepare a TPO skin material. The preparation method is simple and controllable, good in repeatability and low in production cost. The TPO automotive interior material prepared by the method does notneed to add a light stabilizer and has the advantages of light aging resistance, heat resistance, static resistance and the like. The TPO automotive interior material can improve quality and comprehensive performances of finished leather when used for automobile leather. The soft TPO material prepared from the method has the advantages of being comfortable to use and low in odor and VOC, can be recycled and is green and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of automobile interior decoration, in particular to a TPO automobile interior decoration material of graphene-reinforced ethylene propylene diene monomer and its preparation method and application. Background technique [0002] TPO (Polyolefin Thermoplastic Elastomer) is a high-performance polyolefin product, which can be processed like thermoplastics at high temperatures, and exhibits rubber elasticity at room temperature, low density, high flexural modulus, and low-temperature impact resistance. Good, good fluidity, easy processing, and reusable, these characteristics make it promising in the field of automotive interior and exterior decoration. According to relevant data, the use of TPO can reduce the weight of the vehicle by 20% to 25%, and is considered to be an ideal material for lightweight vehicles. [0003] With the advancement of automobile localization and the advancement of science and technolog...
