Description

TAIC助交联法制造紫外光辐照可交联聚乙烯电缆料
技术领域
本发明公开了一种紫外光辐照可交联聚乙烯电缆料的制造方法——TAIC(三烯丙基异氰脲酸酯)助交联法。
背景技术
一般情况下，紫外光辐照可交联聚乙烯电缆料是在聚乙烯树脂中加入紫外光吸收剂、TAC(三烯丙基氰脲酸酯)助交联剂或TAC与多级胺合成助交联剂、阻聚剂和抗氧剂等助剂，经过机械掺混后用双螺杆挤出机挤出造粒而成。TAC助交联法或TAC与多级胺合成助交联法制造的电缆料使用时稳定性尚有欠缺，需要配合的其他助剂成本高。TAC助交联法常用挥发性大的多级胺类配合，不仅有污染、有毒和刺激性大，而且对紫外光发射器损害性强；TAC与多级胺合成助交联法，助剂合成过程中，挥发有毒物质，易燃烧爆炸和污染环境，制造电缆过程中释放刺激性气体较多。
发明内容
为了提高紫外光辐照可交联聚乙烯电缆料的使用稳定性、提高电缆制造效率和克服TAC助交联法(或TAC与多级胺合成助交联法)制造(或使用)成本高、污染大和刺激性强等缺点，在保证紫外光辐照可交联聚乙烯电缆料性能及制造电缆性能的前提下，发明了TAIC(三烯丙基异氰脲酸酯)助交联法，主要内容如下：
1、聚乙烯树脂中加入紫外光吸收剂、助交联剂、阻聚剂、抗氧剂等助剂经过80～140℃机械掺混，再经过双螺杆挤出机145～180℃挤出造粒冷却而成紫外光辐照可交联聚乙烯电缆料。其中助交联剂采用TAIC或TAIC与非TAC助交联剂复合；
2、紫外光吸收剂采用BP(二苯甲酮)或BP与其他类型紫外光吸收剂复合；
3、采用接枝剂和阻聚剂降低电缆料在制造和使用过程中刺激、污染气体的产生、排放；
4、电缆料使用过程中采用常规LED紫外光发生器连续挤出辐照交联。
具体实施方式
1、所需设备：①、高速混合机；②、TSH-75双螺杆混炼挤出造粒机组。
2、所需原料：低密度聚乙烯或线性低密度聚乙烯，紫外光吸收剂、TAIC助交联剂、阻聚剂、抗氧剂等助剂。
3、制造步骤：将聚乙烯树脂、紫外光吸收剂、助交联剂、阻聚剂和抗氧剂等原料一并加入高速混合机内，在一定温度和常压下进行机械混合。一定时间后，将混合物在双螺杆内混炼、挤出、造粒、包装。
4、制造温度：物料混合温度为80～140℃、挤出造粒温度为145～180℃。
5、物料在高速混合机内的混合时间：15～30min。
6、贮藏：常温避光条件下，密封保存。
