Description

一种高弹发泡料及其制作方法
技术领域
本发明涉及高分子领域，尤其涉及一种高弹发泡料及其制作方法。
背景技术
运动休闲、鞋类、安全防护、玩具、医疗复健等大多要求具有高弹、耐磨、防滑、柔软舒适触感等特征。现有市场上大多使用EVA、PE、POE橡胶来架桥发泡制作，而EVA、PE、POE橡胶制作的产品收缩率高达8％，手感不佳，止滑效果差，另由于塑料成份重，稳定性差，填充物碳酸钙含量低，故成本高，耐温差，余边废料回收困难。
发明内容
本发明所要解决的问题是提供一种稳定性高、经济环保、柔软舒适度好的高弹发泡料。
为解决以上问题，本发明通过以下技术方案来实现：
一种高弹发泡材料，包括以下成分组成：SEBS(乙烯、丁烯、苯乙烯共聚物)的重量百分比是20-50％，石蜡油的重量百分比10-30％，EPDM(三元乙丙橡胶)的重量百分比10-30％，填充物CaCO3的重量百分比10-20％，抗老化剂的重量百分比0.5-2％，抗氧化剂的重量百分比0.5-2％。
一种高弹发泡材料的制造方法，包括以下工艺步骤：
1)拌料：将SEBS加入高速混炼机中搅拌20-50秒后加入石蜡油，再搅拌3-10分钟，最后加入EPDM、填充物CaCO3、抗老化剂、抗氧化剂搅料1-3分钟即可；
2)造粒：将已混合好的材料加入同向高速双螺杆挤出机组中造粒，造粒工艺如下：电热片加热温度段中，预热段130-150℃，输送段150-170℃，塑化段170-180℃，冷却段140-150℃；造粒机主机转速300-500转/min，喂料转速30-100转min；
3)卸料：将生产好的原料颗粒装入纸袋中，以25-100KG/包，封包入库。
步骤1)中所述SEBS的重量百分比是20-50％，石蜡油的重量百分比10-30％，EPDM的重量百分比10-30％，填充物CaCO3的重量百分比10-20％，抗老化剂的重量百分比0.5-2％，抗氧化剂的重量百分比0.5-2％。
本发明具有以下有益效果：其一、本发明所述工艺简单，成本低；其二、本发明采用高氢化饱和的苯乙烯类高分子聚合物等材料进行加工，分子量高、耐候性好、耐寒于零下20℃状态下还能保持其弹性和柔韧度，此点对于产品在寒冷地区的使用将有很大助益，解决了传统发泡料耐候性差的弊端；其三、本发明分子量高，在高充填量下仍能保持非常好的弹性，从根本上解决了用EVA、POE等发泡低填充量的缺陷，大大降低了成本，且由于具有高填充性，可达到较小的收缩率和较低的模具缩水量，据统计仅2％的收缩率；其四、由于本产品分子量高，耐温好，最高可达230℃，故对复合发泡产品余边废料的回收再生有优异的活化效果，原因在于使用其发泡材料做产品时所发生的余边废料可100％再生而不浪费材料，此为架桥发泡的一大突破，亦合乎使用绿色环保材料潮流的趋势；其四、其延伸及弹性好，且手感佳，止滑好，可制作出仿PU触感的材质，解决了传统发泡的止滑性差的问题，避免出现人滑倒而造成的安全事故。
