Problems solved by technology

At present, the use of soft-touch materials for automotive interior parts has become the pursuit of high-end models, but traditional soft materials such as PU, PVC and other materials have some unfavorable problems, such as poor high and low temperature resistance, high specific weight, and soft materials. A series of problems such as low strength, excessive VOC emissions, and strong odor limit the application and promotion of these traditional materials in automotive interiors

Abstract

The invention relates to a TPE (thermoplastic elastomer) material applicable to automobile interior decorations and a preparation method thereof. The material comprises the following components in parts by weight: 100-200 parts of SEBS (styrene-ethylene-butadiene-styrene), 100-200 parts of white oil, 20-80 parts of polypropylene, 30-100 parts of filler and 0.2-0.4 part of stabilizer. The method comprises the following steps: slowly mixing the SEBS and white oil in a stirrer at 50-80 DEG C for 20-30 minutes, mixing with the other raw materials and assistants for 20-30 minutes, and adding into a double screw extruder; meanwhile, adding a liquid azeotrope former into first three regions of a vacuum zone by using a melt measuring pump; and carrying out vacuum exhaust until the liquid azeotrope former is thoroughly discharged. The TPE material has the advantages of low smell, high / low-temperature resistance, low atomization value, wear resistance and excellent stretching resistance, is especially suitable for automobile interior decoration materials, has the characteristics of wide application range, high practicality and simple production technique, is more environment-friendly and durable than the existing TPE material, and is worthy of widespread popularization.

Description

technical field [0001] The invention belongs to the technical field of production and processing of polymer modified materials, and in particular relates to a TPE material that can be used for automobile interior decoration and a preparation method. Background technique [0002] The lightweight and environmental protection of automobile materials has become the top priority of the automobile manufacturing industry. At present, the use of soft-touch materials for automotive interior parts has become the pursuit of high-end models, but traditional soft materials such as PU, PVC and other materials have some unfavorable problems, such as poor high and low temperature resistance, high specific weight, and soft materials. A series of problems such as low strength, excessive VOC emissions, and strong odor limit the application and promotion of these traditional materials in automotive interiors. The application of thermoplastic elastomer (TPE) materials in automotive interiors ha...
