Abstract

The invention discloses a TPO automotive trim material with simulated stitching effect. The TPO automotive trim material comprises a sponge layer, a TPO surface layer and a paint from the lower part to the upper part in sequence, wherein the TPO surface layer is prepared by performing extrusion molding on a TPO material; the TPO material comprises the following components in parts by weight: 20 to 40 parts of polypropylene, 10 to 20 parts of low density polyethylene, 5 to 12 parts of polyurethane, 40 to 55 parts of rubber, 12 to 20 parts of tackifying resin, 8 to 14 parts of an inorganic filler, 0 to 8 parts of color master, and 2 to 5 parts of an assistant. The invention further discloses a preparation method of the TPO automotive trim material with simulated stitching effect. The TPO trim material can achieve authentic stitching effect of an automotive trim instrument board or a door sheet, and ensures that automotive trim is high-end oriented; the production technology is simple, the manufacture time can be greatly shortened through a one-step shaping technology, the rejection rate is reduced, and the cost is reduced.

Description

technical field [0001] The invention relates to the field of automotive interior materials, in particular to a TPO automotive interior material with simulated sutures and a preparation method thereof. Background technique [0002] In the car interior design, with stitching effect, it often makes the car interior look high-end. In order to achieve a certain high-end aesthetic effect on the instrument panel, door panels, etc., some stitching effects are often done. By sewing one or more sutures with a sewing machine, a certain aesthetic effect can be achieved. Commonly used materials are wrapped with PVC leather with fabrics. [0003] Due to many reasons, PVC materials with fabrics will always encounter more or less problems when applied to car dashboards or door panels. However, the common slush molding process also has many difficulties, either the stitching effect is unreal, or the scrap rate is extremely high. . At present, some OEMs also use TPO as real sutures, but b...
