Abstract

The invention discloses an environment-friendly type TPO automobile trim material with ultra-soft quality. A TPO surface layer comprises the following components: 10-40 parts of low density polyethylene, 10-40 parts of polypropylene, 10-40 parts of tackifying resin, 30-60 parts of rubber, 1-5 parts of an auxiliary agent, 0-10 parts of an inorganic filling material, and 2-5 parts of a color master batch; and a sponge layer comprises the following components: 35-60 parts of polypropylene, 40-55 parts of a toughening material, 15-25 parts of rubber, and 20-30 parts of a foaming agent. Formulas of the soft TPO surface layer and the soft sponge layer improve soft handfeel of the trim material, and increases comfort level of the product; soft aqueous polyurethane paint which is used for surface coating, the composite soft sponge, and the three-layer structure improve soft performance of the material, reduce density of the product, satisfy the light weighting demand of the product, reduce VOC content of the material in the vehicle, and improve environmental protection performance of the product.

Description

technical field [0001] The invention relates to the field of automotive interior materials, in particular to an ultra-soft environment-friendly TPO automotive interior material and a preparation method thereof. Background technique [0002] In the interior design of automobiles, in order to achieve a certain feel and aesthetic effect on the instrument panel and door panels, some treatments are usually done on the skeleton. At present, the mainstream methods are: slush molding, polyurethane spraying or direct use of ABS skin. [0003] Taking the interior material of the instrument panel as an example, the soft material can be slush-molded polyvinyl chloride, polyolefin elastomer material, etc. In terms of texture and appearance, polypropylene injection molded parts are far from soft materials. On the other hand, the mold life of slush-molded PVC is generally short, and the interior materials contain halogens and plasticizers, which are not environmentally friendly; polyolefi...
