Description

改性EVA发泡体及其制备方法与应用
技术领域
本发明涉及一种改性EVA发泡体及其制备方法与应用。
背景技术
射出乙烯醋酸乙酯共聚物(简称EVA)是将EVA原材料塑炼造粒高温熔融后，通过管道射出到模具，继而在模外发泡得到的产品。一般运动鞋的鞋底是由发泡中底和耐磨橡胶大底组成，由于乙烯与醋酸乙烯共聚物(EVA)具有很好的可塑性、弹性、可加工性，发泡后材料密度小、力学性能好、易着色等优点。目前绝大多数运动鞋的中底或鞋垫采用EVA发泡材料。
一般射出EVA产品存在收缩和压缩变形严重等缺点，对后续的生产和使用有很大的障碍和局限，因此，需要一种新的改性EVA发泡体。
发明内容
本发明的目的是提供一种改性EVA发泡体及其制备方法与应用。
本发明提供的改性EVA发泡体，包括乙烯醋酸乙酯共聚物、聚烯烃弹性体(简称POE)、木质纤维素粉体、发泡剂、架桥剂、活性剂和氧化锌。
上述改性EVA发泡体也可只由上述组分组成。
其中，所述乙烯醋酸乙酯共聚物的数均分子量为400-4000，优选800-2000，所述乙烯醋酸乙酯共聚物中醋酸乙酯(VA)的质量百分含量为10-21％，优选16-19％；
所述聚烯烃弹性体的数均分子量为400-4000，优选600-2000；
所述木质纤维素粉体选自针叶材植物秆芯粉体、阔叶材植物秆芯粉体和禾本科植物秆芯粉体中的至少一种，优选大麻杆芯、汉麻秆芯、黄麻杆芯、亚麻杆芯、剑麻杆芯、苎麻杆芯和竹子中的至少一种，所述木质纤维素粉体的粒径为200目-1000目，优选400-800目，更优选500目；
所述发泡剂选自偶氮二甲酰胺、对甲苯磺酰肼和偶氮二甲硫胺中的至少一种，优选偶氮二甲酰胺；
所述架桥剂选自过氧化二异丙苯(DCP)、硫磺和二叔丁基过氧化物中的至少一种，优选过氧化二异丙苯；
所述活性剂选自硬脂酸、碳酸镁和氧化钙中的至少一种，优选硬脂酸。
所述乙烯醋酸乙酯共聚物、所述聚烯烃弹性体、所述木质纤维素粉体、所述发泡剂、所述架桥剂、所述活性剂和所述氧化锌的质量比为70∶30∶20-80∶3.0-5.0∶0.4-1.0∶1.0-3.0∶0.5-2.5，优选70∶30∶40-70∶3.5-4.5∶0.6-0.8∶2-2.5∶1-1.5，更优选70∶30∶50∶4∶0.6∶2∶1。
本发明提供的制备所述发泡体的方法，包括如下步骤：将前述各组分混合后进行硫化成型，得到所述发泡体。
该方法所述硫化步骤中，温度为165-175℃，优选168-175℃，更优选175℃，时间为5～15分钟，优选6-10分钟，更优选6分钟。
另外，为了使各组分混合得更加均匀，所述制备发泡体的方法，还包括如下步骤：在所述硫化步骤之前，所述混合步骤中混合的方式可为混炼，可包括如下步骤：将EVA、乙烯醋酸乙酯共聚物、POE和木质纤维素粉体进行混炼(该步骤中，温度不超过70度，混炼温度为80-100℃，混炼时间可为0.2小时)，同时将发泡剂、架桥剂、活性剂和氧化锌于另一密炼机中进行混炼(该步骤中，温度不超过70℃，混炼温度为100-110℃，混炼时间为0.1小时)。
上述本发明提供的发泡体在制备鞋底中的应用，及以所述发泡体为底的鞋底，也属于本发明的保护范围。其中，所述鞋底为鞋中底或鞋大底。
本发明改性发泡体EVA不仅具有较轻重量的性能，而且还具有较佳的耐久性能，由其制成的鞋中底重量轻、耐久性好，可适用于用作耐久性能要求较高的鞋大底。
本发明采用乙烯醋酸乙酯共聚物(EVA)、聚烯烃弹性体(POE)和木质纤维素粉体为主体胶料，经混炼、造粒和射出硫化制成。该改性EVA发泡体的比重在0.2以下，质量轻，耐压缩歪在50％以下，能经受长时间的穿着，以该改性发泡体制备的鞋中底轻质、耐久性能佳，适用于各种竞技类和休闲类的鞋中底，具有重要的应用价值。
