Description

一种防护纳米弹性鞋垫制备方法
技术领域
本发明涉及一种防护纳米弹性鞋垫制备方法。
背景技术
特殊工种如五金制造业、林木业、探勘及救援作业的工作人员,需要在一些特殊环境下进行工作。因此,对于特殊工种的特种安全防护鞋需要作出新的设计。由于职业的特殊性,如部队、消防等人员的负荷量远远超过常人,经常会出现一些下肢损伤,主要表现在足弓韧带过度拉伸、足部的跟骨痛、前脚掌痛等症状。这是由于前掌和后跟部位的峰值压力过大,足部神经受到严重压迫所致。针对这种情况,需要对防护鞋垫做出改进,现在的使用的鞋垫种类比较多,有弹性的发泡材料EVA、TPU材质、布料、还有皮制等多种,然而这些鞋垫对足部的防护力度明显不足。
发明内容
为了克服上述缺陷,本发明提供了一种改变弹性体的物理性质,增强催化性、稳定性等化学性质,使力学性也得到改善的防护纳米弹性鞋垫。
本发明解决其技术问题所采用的技术方案是:一种防护纳米弹性鞋垫制备方法,包括如下步骤:
S1、塑炼:取天然橡胶投入开炼机塑炼,所述开炼机的辊筒温度为40-50℃;
S2、混炼:取一定配比量的丁腈橡胶加入到开炼机内与天然橡胶混炼;
S3、香料配比:取20-40份盐酸洗必泰粉,16-20份纳米二氧化硅,14-18份沸石粉,24-30份电气石粉,5-15份甲壳胺粉混合成香料粉;
S4、搅拌:向开炼机内加入上述配比量的香料搅拌均匀,辊筒温度70-80℃,辊距2-3mm;
S5、助剂配比:向开炼机内依次加入配比量的增塑剂、碳酸钙、炭黑、氧化锌、十八碳烷酸、促进剂、防老剂、发孔剂以及硫磺;
S6、混炼:将上述开炼机内的混合物进行混炼50-60分钟形成混炼胶;
S7、延压:将混炼胶在压延机上制成胶片;
S8、硫化:将胶片通过挤出机压出到模具中进行硫化,硫化温度110℃,硫化时间1.2h;
S9、出片:从模具中取出,用切片机按要求厚度进行切片。
在本发明一个较佳实施例中,盐酸洗必泰粉、纳米二氧化硅、沸石粉、电气石粉、甲壳胺粉的粒径为10-20nm。
在本发明一个较佳实施例中,增塑剂为邻苯二甲酸二辛酯;所述防老剂为2,2,4-三甲基-1,2-二氢化喹啉;所述发孔剂为N,N-二亚硝基五亚甲基四胺;所述促进剂为2,2’-二硫代二苯并噻唑。
本发明的有益效果是:采用上述结构后,借助橡胶材料弹性优良的特性,将纳米改性材料介入,改变基质单一材料的结构参数,改变弹性体的物理性质,增强催化性、稳定性等化学性质,使力学性也得到改善;高比表面积的纳米材料表面存在大量的残键,其表面能对气体和细菌有强烈的吸附作用,可使细菌的细胞膜或细胞原生质活性酶得到破坏,从而使细菌死亡;并可与鞋内的异臭分子或者任何形式的水分子、氧分子、氮分子结合,发生化学反应,改变异臭分子的性质,使异臭分子消失及依附微粒而消失下沉。
