Description

PET热缩套管的制备方法
技术领域
本发明涉及一种PET热缩套管的制备方法。
背景技术
热缩套管被广泛应用于电子元器件上，如电容、电感、电池等上面，作为这些电子元件的外部绝缘包覆层，一方面可以对内部的电子元件进行有效的防护，另一方面，在热缩套管的外表面上可以标注电子元件的信息，以便于识别，热缩套管通过在配方中加入不同的颜料色母可以制成各种颜色，在增强电子元件的美观性同时，对不同类或是同类的不同型号的电子元件加以区分。但通常的热缩套管主要原料采用PVC，这种产品通常韧性差，相对较脆，比较容易产生裂纹破损，耐侯性能也较差。最主要的是PET产品能够改善上述性能外还具有明显的环保性能。
发明内容
为了克服上述利用PVC作为主要原料制备的热缩套管存在的不足，本发明提供一种工艺简单、操作方便的PET热缩套管的制备方法，有效改进了热缩套管的各种性能。
本发明所要解决的技术问题是：一种PET热缩套管的制备方法，其特征是采用如下工艺步骤：
a.配料：原料包括PET(聚对苯二甲酸乙二醇酯)、POE(聚烯烃热塑性弹性体)、TPEE(热塑性聚酯弹性体)及PC滑剂(聚碳酸酯)，配方重量组份为：PET 100份，POE 1～15份，TPEE 2～50份，PC滑剂0.5～8份，均匀混合。其中，POE起到了加强产品韧性的作用，TPEE起到了抗冲、改性的作用，提高在热缩套管表面印刷性能，PC滑剂提高了产品的表面光洁度。
b.除湿干燥：采用除湿干燥机，干燥时间控制在2～6小时。
c.挤塑：采用挤塑机，设置五个温度控制段，第一温度控制段180～200℃，第二温度控制段200～230℃，第三温度控制段220～250℃，第四温度控制段240～250℃，第一温度控制段235～255℃，挤出半成品塑管。
d.一次冷却：对挤出的半成品采用冷却水冷却，控制水温≤20℃，保持塑管具有延展性。
e.管体成形：经过一次冷却的塑管牵引进入定型套，在定型套前端加入蒸汽，后端加入室温水，向塑管内鼓入压缩空气膨胀，由定型套对膨胀后的塑管进行定形，压力保持0.3～2kg。
f.二次冷却：采用室温水对定形后的塑管进行再次冷却，制成热缩套管。
g.后处理：对热缩套管进行压扁、卷绕、包装。
为了制成各种颜色的热缩套管，进一步地：配方中还加入颜料色母，重量组份为1～10份。
为了提高产品的耐高温性，进一步地：配方中还加入耐温助剂PET-C，重量组份为0.3～6份。
为了使最后成品达到最佳的性能，更进一步地：优选配方为，PET 100份，POE 2～8份，TPEE 2.5～35份，PC 1～2份，颜料2～6份，PET-C 0.5～2份。
本发明工艺简单，操作方便，制得的热缩套管较原有的PVC产品相比，在产品的韧性、表面光洁度和耐高温性、印刷性方面都有很大的优化和性能改善，最主要的是PET为环保无污染材料，故所做产品符合欧盟和我国环保要求之趋势。
