Description

夜光热收缩管的制造方法
技术领域
本发明涉及一种辐射交联热收缩管的制造方法,特别涉及一种夜光热收缩管的制造方法。
背景技术
目前,市场上的热收缩管普遍应用于电力、电器、医疗等产业。由于现有的热收缩管不能在黑暗中发光,使得应用范围难以扩展。随着科技的进步,现有产品的应用已经远远满不能满足市场的需求。根据国内外客户的需求,为拓展热收缩管的应用范围,提高该产品的科技含量,增加其附加值势在必行。
发明内容
本发明的目的在于克服上述不足之处,提供一种工艺简单、制成成品发光性能优良、应用广泛的夜光热收缩管的制造方法。
为实现上述目的本发明所采用的技术方案是:一种夜光热收缩管的制造方法,是经混炼、造粒、挤出、辐照、扩张完成;其特征在于按重量份数比由如下原料制造而成:
聚烯烃材料采用型号为EVA1405的聚乙烯-醋酸乙烯共聚物:60-90份,配以超长余辉发光粉采用型号为LG402的硅铝酸锶:5-50份;
或聚烯烃材料采用型号为PE18D的聚乙烯:60-90份,配以超长余辉发光粉采用型号为LG502的硅铝酸锶:5-50份;
抗老化剂采用型号为BNX1010的酚类抗氧剂:            0.5-2份;
光稳定剂采用型号为GW540的受阻胺类光稳定剂:        0.5-2份;
交联剂采用型号为TMPTA的三羟甲基丙烷三丙烯酸酯:    0.5-2份;
乙烯共聚物采用型号为POE8410:                      5-10份;
所述夜光热收缩管产品设为内外双壁结构时,其收缩管内壁采用聚烯烃阻燃白色母料;
实施步骤如下:
(1)混炼、造粒:
超长余辉发光粉与聚烯烃材料在混合之前要充分烘干,在80-85℃以下干燥2±0.5小时,按上述重量份数配比加入超长余辉发光粉、聚烯烃材料及上述各种原料均匀混合,用双螺杆或开炼机和单螺杆挤出机混炼,然后造粒。
(2)挤出成型:
使用塑料挤出机,采用45#或50#挤出机组,挤出成型;
挤出温度:1区:110±10℃、2区:120℃±10℃、3区:125℃±10℃、4区:128℃±10℃,机头温度:110℃±10℃;
(3)辐照:
