Embodiment 1

[0020] Weigh each raw material according to the parts by weight of the component formula 1 shown in Table 1, among which 150 parts of SEBS with a weight average molecular weight greater than 80,000 are weighed, 125 parts of white oil with a pour point lower than minus 25°C are weighed, and 125 parts of white oil with a crystallinity lower than 30% grade is 62.5 parts of ST612 high-permeability polypropylene, weigh 78.5 parts of filler, calcium carbonate is used as filler, diatomite, wollastonite, talcum powder, zeolite powder, molecular sieve, carbon black, porous alumina and For one or more of the hollow glass microspheres, weigh 0.4 parts of the antioxidant. The antioxidant is selected from phenols, and one or more mixtures of phosphites and sulfur-containing esters can also be used. All of the above raw materials can be obtained in the market, or can be obtained by using existing technologies.

[0021] Add the prepared SEBS, polypropylene and filler into the mixer, and stir...

Abstract

The invention relates to a TPE (Thermo Plastic Elastomer) material capable of being recovered after stress and deformation at low temperature, and a preparation method and application thereof. The TPE material is prepared from the following components in parts by weight: 100 to 200 parts of SEBS, 125 to 300 parts of white oil, 45 to 120 parts of polypropylene, 50 to 200 parts of filler and 0.1 to 1.5 part of antioxygen. In order to prepare the TPE material, the method comprises the steps of screening, weighing and preparing the SEBS, the white oil, the polypropylene, the filler and the antioxygen; adding the prepared SEBS, the prepared polypropylene and the prepared filler into a stirring machine, and stirring at slow speed to 45 DEG C; slowly adding the prepared white oil, and after the white oil is uniformly absorbed, adding the antioxygen; discharging when the temperature is higher than 85 DEG C, and feeding a discharged material into a double-screw extruder for pelleting. The TPE material prepared through the technical scheme can automatically get back into shape after an external force is removed if being stressed to be curled for a long time at low temperature, is excellent in inoxidizability, durable and not easy to abrade and deform, and can be used for manufacturing a foot pad.

Description

technical field [0001] The invention relates to the preparation and application of a thermoplastic elastomer material, in particular to a TPE material capable of being deformed under low temperature and its preparation method and application. Background technique [0002] At present, the main function of car floor mats is to keep the original car carpet dry and clean, free from dust, muddy water and debris brought in by the soles of the feet. In addition, during use, the foot pads are required not to have adverse effects on the handling and driving of the car. Therefore, it is necessary to prevent the foot pads from deforming after being trampled on, or to quickly return to their original shape when the external force is removed after deformation. At present, although some mats can meet the above requirements at room temperature, under low temperature conditions, especially in winter in regions with higher latitudes, such as Northeast China, northern United States and northe...
