Description

通信光缆阻水材料及其制备方法
技术领域
本发明涉及光电子信息技术领域，具体地讲涉及一种对通信光缆进行包扎和填充的通信光缆阻水材料及其制备方法。
背景技术
为了确保通信光缆阻水防潮，生产通信光缆的厂家需要用阻水材料(阻水带和阻水纱)对通信光缆进行包扎和填充。
国内外科研人员都有一个思维定式，即：采用再湿性胶粘剂(以水为溶剂)将丙烯酸超强吸水粉粘接到无纺布和芳纶纱上而制得阻水带和阻水纱。
目前生产通信光缆阻水带或阻水纱的厂家均采用再湿性胶粘剂将阻水粉(超强吸水剂)粘接到特种无纺布或芳纶纱上而制得产品。该制备方法为了避免阻水粉吸收再湿性胶粘剂中的水而膨胀，在生产过程中采用迅速涂胶、迅速布粉、迅速复膜和迅速干燥。该工艺存在阻水粉从基材上脱落、复膜不牢和含水量较高的弊端，严重影响了产品质量。
发明内容
本发明的目的在于提供一种不脱粉、复膜牢和、含水量极低的通信光缆阻水材料及其制备方法，其制备方法简单。
为了实现上述目的，本发明的技术方案是：通信光缆阻水材料，它由遇水膨胀阻水涂料、特种无纺布、芳纶纱组成，其特征是遇水膨胀阻水涂料由超强吸水剂、粘接剂、无水醇类溶剂组成，其各组份所占总重量百分比为：
超强吸水剂 22-42
粘接剂 1-30
无水醇类溶剂 42-62
遇水膨胀阻水涂料滚涂在特种无纺布或浸涂在芳纶纱上。
如上所述的遇水膨胀阻水涂料，其各组份所占总重量最佳百分比为：
超强吸水剂 32
粘接剂 16
无水醇类溶剂 52。
所述的超强吸水剂为丙烯酸-聚乙二醇二丙烯酸酯共聚物超强吸水剂或/和聚丙烯酸酯超强吸水剂或/和淀粉接枝超强吸水剂。
所述的粘接剂为聚乙烯吡咯烷酮或/和乙烯基吡咯烷酮/醋酸乙烯共聚物或/和乙烯基吡咯烷酮/乙烯醇共聚物。
所述的无水醇类溶剂为无水甲醇或/和无水乙醇或/和无水丙醇。
通信光缆阻水材料的制备方法，其特征是按下列步骤实现：
1)遇水膨胀阻水涂料的制备：取超强吸水剂、粘接剂、无水醇类溶剂，其各组份按总重量百分比：超强吸水剂 22-42、粘接剂 1-30、无水醇类溶剂 42-62，制成遇水膨胀阻水涂料；
2)将遇水膨胀阻水涂料滚涂在特种无纺布或者浸涂在芳纶纱上而制得通信光缆阻水材料。
所述的遇水膨胀阻水涂料的制备，以丙烯酸-聚乙二醇二丙烯酸酯共聚物超强吸水剂为体质填料、以乙烯基吡咯烷酮/醋酸乙烯共聚物为粘接剂、以无水乙醇为溶剂，制成遇水膨胀阻水涂料。
所述的遇水膨胀阻水涂料的制备，以聚丙烯酸酯超强吸水剂为体质填料、以聚乙烯吡咯烷酮为粘接剂、以无水甲醇为溶剂，制成遇水膨胀阻水涂料。
所述的遇水膨胀阻水涂料的制备，以淀粉接枝超强吸水剂为体质填料、以乙烯基吡咯烷酮/乙烯醇共聚物为粘接剂、以无水丙醇为溶剂，制成遇水膨胀阻水涂料。
所述的遇水膨胀阻水涂料的制备，以丙烯酸-聚乙二醇二丙烯酸酯共聚物和聚丙烯酸酯超强吸水剂为体质填料、以聚乙烯吡咯烷酮和乙烯基吡咯烷酮/醋酸乙烯共聚物为粘接剂、以无水甲醇和无水乙醇为溶剂，制成遇水膨胀阻水涂料。
本发明采用超强吸水剂、粘接剂、无水醇类溶剂制成遇水膨胀阻水涂料，其超强吸水剂在醇类物质中表现为惰性；其粘接剂既具有醇溶性又具有水溶性又不吸潮，且具有良好的粘结性、再湿性和成膜性，而无水醇类溶剂不含水。如乙烯基吡咯烷酮/醋酸乙烯共聚物(PVP/VA)为粘接剂，它既具有醇溶性又具有水溶性又不吸潮，且具有良好的粘结性、再湿性和成膜性；丙烯酸-聚乙二醇二丙烯酸酯共聚物超强吸水剂吸收纯水后可膨胀1000倍以上，而在醇类物质中表现为惰性。本发明正是利用上述两种高分子材料各自的特点，制得的涂料在固化前与一般涂料没有区别，而在其固化后遇水就会发生膨胀。由于粘接剂具有良好地粘结性，不脱粉、复膜牢和，即使是单面阻水带(通信光缆阻水材料)也不会发生阻水粉(如PVP/VA)从无纺布上脱落的质量问题；由于遇水膨胀阻水涂料是以无水醇类为溶剂(如无水乙醇)，因而采用该涂料制得的通信光缆阻水材料(阻水带和阻水纱)含水量极低(0.55％)，而信息产业部通信业标准YD/T1115.1-2001、YD/T1115.2-2001中阻水带、阻水纱的含水量只要求≤9％就合格了。
本发明由于采用无水醇类为溶剂(如无水乙醇)，不用迅速涂胶、迅速布粉、迅速复膜和迅速干燥，因而其制备方法简单。性能指标如下：
1、遇水膨胀阻水涂料各项理化性能指标如下表所示
备注：本指标按DZD-0.30·50 YD/T 1115.1-2001要求测试。
本发明用遇水膨胀阻水涂料制备通信光缆阻水带和阻水纱，主要技术指标如“膨胀速率”和“膨胀倍率”达到或超过信息产业部通信行业标准，“成品含水量”远远超过信息产业部通信行业标准，这对确保通信光缆的安全运行具有十分重耍的意义。由于采用遇水膨胀阻水涂料制备通信光缆阻水带和阻水纱工艺简单，工艺指标易于控制，次品废品率低，能耗低，故能较大幅度降低阻水带和阻水纱的生产成本。
