Abstract
The invention belongs to the technical field of polymers and specifically relates to a thermoplastic elastic material for producing a low-VOC mud guard and a preparation method of the thermoplastic elastic material. The thermoplastic elastic material for producing the low-VOC mud guard. The thermoplastic elastic material for producing the low-VOC mud guard comprises the following raw materials: polypropylene, a polyolefinelastomer, ethylene-propylene-dienemonomer rubber, a filling material and auxiliaries. The preparation method of the thermoplastic elastic material for producing the low-VOCmud guard comprises the following steps: (1) mixing the raw materials according to a certain proportion, and carrying out uniform stirring at room temperature to obtain a mixed material; (2) conveying the mixed material into an extruder at constant speed, and setting ten heating regions on the extruder; and (3) carrying out pelletizing after extruding. The thermoplastic elastic material for producing the low-VOC mud guard, disclosed by the invention, is wear-resistant, bending-resistant, high in tearing strength, low-temperature-resistant, low in organic volatile content and high in normal-temperature / low-temperature shock resistance; and the preparation method disclosed by the invention is simple in process, easy to operate and high in product yield.
