Description

一种高分子EVA卷芯工艺
技术领域
本发明属于功能膜类制作技术领域,尤其与具有解决功能膜类的高分子EVA卷芯工艺。
背景技术
锂电池的结构中,隔膜是关键的内层组件之一。隔膜的性能决定了电池的界面结构、内阻等,直接影响电池的容量、循环以及安全性能等特性。隔膜的主要作用是使电池的正、负极分隔开来,防止两极接触而短路,此外还具有能使电解质离子通过的功能。隔膜材质是不导电的,其物理化学性质对电池的性能有很大的影响。而对于锂电池系列,由于电解液为有机溶剂体系,因而需要有耐有机溶剂的隔膜材料,一般采用高强度薄膜化的聚烯烃多孔膜。但是随着市场竞争的关系,现有市面上的隔膜厚度都是5μ左右,但是越薄的膜就越容易出现质量问题,比如褶皱不平整,在长度200-500米之间容易产生高不良率。之前厂商一直使用工业纸管,但是厚度只能控制在不低于12μ,12μ以下还是会出现质量问题。
发明内容
针对上述背景技术存在问题,本发明旨在提供一种高分子EVA卷芯工艺。
为此,本发明采用以下技术方案:一种高分子EVA卷芯工艺,其特征是,包括以下步骤:
第一步,准备原料,所述原料包括醋酸乙烯化合物、碳酸钙、三元乙丙胶、过氧化二异丙苯、氧化锌、硬脂酸锌和钛白粉,其所占百分质量比分别为:80%、5%、5%、2%、2%、2%和4%;
第二步,将上述原料混合后进行搅拌;
第三步,将搅拌后的混合物进行颗粒烘烤;
第四步,将烘烤后的原料放入注塑机中进行注塑,注塑参数为:压力40KPA,温度85摄氏度,射速60S;
第五步,注塑成形后待材料缓慢冷却至5摄氏度后静置,静置时间为1小时;
第六步,静置后对材料进行打磨处理,打磨参数为:砂轮转速6000转/分,砂轮走道速度1米/2分钟;
第七步,将成形后的材料进行校验、除尘和打包,完成卷芯工艺。
本发明可以达到以下有益效果:本发明的原材料通过结合醋酸乙烯化合物、碳酸钙、三元乙丙胶、过氧化二异丙苯、氧化锌、硬脂酸锌和钛白粉,其成形的产品薄性能更好,性能包括韧性,硬度,张力,释缓力,回弹性,收缩力(1.6-1.7)。
