Embodiment 1

[0018] Mix 30g of eucommia gum with 70g of polypropylene, 5g of zinc oxide, 0.4g of NS, 3g of SA, 2g of anti-264, 1g of anti-1010, and 0.5g of sulfur in an internal mixer. Set the temperature at 155°C, add TPI, PP, and all small materials into the internal mixer, and banbury for 15 minutes; add S at 15 minutes, and continue banbury for 5 minutes; the total banbury time is 20 minutes, and the sheet is removed by cold roll. During the tableting process, set the temperature at 175°C; put in the rubber material, preheat for 15 minutes; deflate 10 times, heat press for 3 minutes; cold press for 15 minutes.

Embodiment 2

[0020] Mix 40g of eucommia gum with 60g of polypropylene, 5g of zinc oxide, 0.4g of NS, 3g of SA, 2g of anti-264, 1g of anti-1010, and 0.5g of sulfur in an internal mixer. Set the temperature at 155°C, add TPI, PP, and all small materials into the internal mixer, and banbury for 15 minutes; add S at 15 minutes, and continue banbury for 5 minutes; the total banbury time is 20 minutes, and the sheet is removed by cold roll. During the tableting process, set the temperature at 175°C; put in the rubber material, preheat for 15 minutes; deflate 10 times, heat press for 3 minutes; cold press for 15 minutes.

Embodiment 3

[0022] Mix 50g of eucommia gum with 50g of polypropylene, 5g of zinc oxide, 0.4g of NS, 3g of SA, 2g of anti-264, 1g of anti-1010, and 0.5g of sulfur in an internal mixer. Set the temperature at 155°C, add TPI, PP, and all small materials into the internal mixer, and banbury for 15 minutes; add S at 15 minutes, and continue banbury for 5 minutes; the total banbury time is 20 minutes, and the sheet is removed by cold roll. During the tableting process, set the temperature at 175°C; put in the rubber material, preheat for 15 minutes; deflate 10 times, heat press for 3 minutes; cold press for 15 minutes.

Abstract

The invention relates to a preparation method and application of a eucommia ulmoide gum shape memory material. The process of firstly, banburying and secondly, tabletting is adopted. The composite isprepared through the dynamic vulcanization technology. The material has the two beneficial effects that firstly, the impact resistance is excellent, and the impact strength of the material is improvedby more than three times compared with that of common PP materials; and secondly, shape memory performance is achieved.

Description

technical field [0001] The invention relates to a preparation method and application of an Eucommia gum shape memory material. Background technique [0002] With the rapid development of the automobile industry, the lightweight of automobiles has become a trend in the development of the automobile industry. Therefore, more and more automobile parts use plastics to replace metals to reduce the weight of automobiles. In addition, automobile bumpers are inevitably subjected to external shocks during use, and sometimes produce irreversible deformations. At this time, the recoverability of bumpers is particularly important. [0003] Automobile bumpers mostly use polypropylene (PP) as the main raw material. Since the bumper is a thin-walled large-scale structural component with a large surface area and a relatively complex shape, it will be affected by factors such as impact during use, so the bumper material needs to be higher. Fluidity, rigidity, toughness, heat resistance, etc...
