Description

自修复高分子防水卷材及其制备方法
技术领域
本发明涉及建筑防水材料技术领域，尤其是一种自修复高分子防水卷材及其制备方法。
背景技术
雨水、地下水和生活用水渗入建筑中会对建筑的骨架结构和墙面状态造成损害，影响建筑质量，缩短建筑的使用年限，因此，建筑防水工程是保证工程质量的基础。
近年来，随着人们对生态环境问题的重视，屋面种植技术在建筑工程中得到广泛推广，不仅可提高建筑的外观美观度，更重要的是能够改善建筑屋面生态环境，提供更环保的居住、工作环境。但目前屋面种植技术的发展受到限制，主要体现在受到建筑防水卷材的限制，屋面种植会对防水卷材造成破坏，一方面是植物的根系生长会刺破防水层，另一方面是防水卷材长期处于植物种植潮湿土壤环境的影响下，容易发生老化而导致力学性能下降，出现脆化、开裂的现象。
针对防水卷材在屋面种植技术的影响下容易受损的问题，行业中进行了多方面的技术开发，而由于更换防水卷材所涉及的要素较多，直接更换受损防水卷材的成本较高，目前主要的解决方案在于针对防水卷材本身进行改进。
例如申请号为201610908739.1的中国专利申请公开了一种金属芯自修复阻根防水卷材及其制备方法，其包括金属芯层，金属芯层的两侧分别设置有高分子层，高分子层远离金属芯层的一侧或两侧分别设置有非固化橡胶层，非固化橡胶层的外表面设置有防粘隔离层；所述非固化橡胶层的各组分，质量份为：基质沥青30～50份、环烷油6～8份、SEPS橡胶12～16份、聚异丁烯10～15份、改性添加剂0.5～0.8份、增粘树脂5～10份、反应活性剂0.1～0.5份、纳米碳酸钙15～25份，化学阻根剂0.5～1.0份；本发明集密封防水和多重阻根融合一体，具有自修复、抗穿刺、密封粘结、耐老化，使用寿命长的特点；同时本发明还具有多道阻根功能，对于防止植物根穿刺具有多重保险作用，解决了屋顶绿化植物根穿刺防水层的问题。
目前行业中多采用与上述专利中技术方案类似的技术，主要是通过增强防水卷层的抗穿刺能力来提高防水卷层的使用寿命，但防水卷层的自修复能力并不突出。
发明内容
本发明所要解决的技术问题是：提供一种具有良好自修复能力的自修复高分子防水卷材。
为解决上述技术问题本发明所采用的技术方案是：自修复高分子防水卷材，所述防水卷材由自修复层和两层分别设置在自修复层两侧的高分子层组成。
进一步的是：所述自修复层的原料按质量份数计包括：100份107硅橡胶、1～5份正硅酸乙酯、1～5份羟基硅油、0.1～0.2份二月桂酸二丁基锡、0.1～0.5份氨基官能团硅烷、10～30份微胶囊；还包括占原料总质量0.1％～1％的阻根剂。
进一步的是：所述微胶囊为异氰酸酯类微胶囊或环氧类微胶囊。
进一步的是：所述微胶囊为环氧树脂微胶囊。
进一步的是：所述高分子层与自修复层粘接，高分子层靠近自修复层的一面进行电晕处理并接枝反应性单体；反应性单体的一端为含双键的烯烃结构，另一端为环氧基或异氰酸酯基。
进一步的是：所述反应性单体的接枝率为5％～15％。
进一步的是：所述高分子层为高分子膜或高分子片材。
进一步的是：所述高分子膜为聚丙烯膜、聚烯烃膜、聚酯膜、聚氯乙烯膜的中一种或多种。
进一步的是：所述高分子片材的材质为TPO、PVC、EVA、HDPE、LDPE中的一种或多种。
本发明还公开了制备上述自修复高分子防水卷材的方法，包括以下步骤：
步骤一、按配比将107硅橡胶、正硅酸乙酯、羟基硅油、二月桂酸二丁基锡、氨基官能团硅烷和阻根剂混合，在80～120r/min的搅拌速度下搅拌至混合均匀；
步骤二、加入微胶囊在10～30r/min的搅拌速度下搅拌至混合均匀，得到有机硅预聚体；
步骤三、将有机硅预聚体涂覆在高分子层的表面，经真空脱泡、浸渍玻璃纤维后再涂覆一层机硅预聚体，再次真空脱泡、浸渍玻璃纤维后，在室温下静置固化；
步骤四、卷绕、传递、包装。
本发明的有益效果是：
1、本发明中采用微胶囊为防水卷材提供良好的自修复功能，在防水卷材被植物根系刺破后能够快速进行修复，保证防水卷材的防水功能；
2、本发明中微胶囊与植物种植的潮湿土壤环境适配性良好，在不使用催化剂的情况下微胶囊的芯材即可在潮湿环境中发生固化，完成对防水卷材的修复，极大简化了自修复的周期；
3、本发明中的自修复层采用室温固化的有机硅作为基体，其前驱体为液态，固化过程不需要高温反应，可以减少自修复成型过程中微胶囊的破损，能够极大提高微胶囊的存留率；
4、本发明中的有机硅基体材料的化学键键能高，能够为基体材料赋予良好的热稳定性和阻燃性；
5、本发明所公开的防水卷材兼具良好的防水性、阻根性、自修复性和阻燃性，使用寿命长。
附图说明
图1为本发明中防水卷材的结构示意图；
图中标记为：100-自修复层、200-高分子层。
具体实施方式
为了便于理解本发明，下面结合附图以及实施例对本发明进行进一步的说明。
如图1所示，本发明所公开的自修复高分子防水卷材由自修复层100和高分子层200组成，两层高分子层200粘接在自修复层100的两侧面上。
本发明中自修复层的原料按质量份数计包括：100份107硅橡胶、1～5份正硅酸乙酯、1～5份羟基硅油、0.1～0.2份二月桂酸二丁基锡、0.1～0.5份氨基官能团硅烷(KH550)、10～30份微胶囊；还包括占原料总质量0.1％～1％的阻根剂。
本发明中的自修复层采用室温固化有机硅作为基体，添加微胶囊提供良好的自修复功能。微胶囊与屋面种植技术的潮湿土壤环境非常适配，当防水卷材被刺破时，在不使用催化剂的情况下，微胶囊的芯材即可释放出来在潮湿环境中发生固化，完成对防水卷材的自我修复。微胶囊可采用异氰酸酯类微胶囊或环氧类微胶囊，本发明中优选无锡惠隆电子材料有限公司生产的环氧树脂微胶囊，该环氧树脂微胶囊微的囊壁为脲醛树脂，芯材为E-51环氧树脂，外观为规则的球形，表面光洁，形态规整，不粘连，微胶囊的粒径较小且分布相对较窄，平均粒径为12μm，包封率为64.32％，囊芯含量77.06％。另外，本发明中的107硅橡胶为粘度为1～5Pa.s的透明流动液体，阻根剂为德国朗盛Preventol B2和B5阻根剂，上述阻根剂对温度的适应性较广，在建筑工程所处的环境温度中都能起到作用，并且用量较少，对节约成本有一定帮助。本发明中集体的前驱体为液态，在固化过程中不需要高温反应，可以有效减少自修复层成型过程中微胶囊的破损，从而提高微胶囊的存留率；同时有机硅基体材料中的Si-O键能比C-C键键能高，能够为自修复层提供较好的热稳定些，基体中大量的Si组分还能为自修复层提供较好的阻燃性。自修复层中还可掺入改性玻璃纤维布以提高自修复层的强度。
本发明中的高分子层采用高分子膜或高分子片材，高分子膜可选用聚丙烯膜、聚烯烃膜、聚酯膜、聚氯乙烯膜的中一种或多种，若选用高分子膜，其厚度为50～100μm；高分子片材可选用TPO、PVC、EVA、HDPE、LDPE中的一种或多种。高分子层与自修复层粘接时，为了保证两者之间的粘接力，可以对高分子层与自修复层相粘接一面的表面进行电晕处理并接枝反应性单体，反应性单体的一端为含双键的烯烃结构，另一端为环氧基或异氰酸酯基，优选为甲基丙烯酸缩水甘油酯，反应性单体的接枝率为5％～15％。
在制备本发明上述内容所公开的防水卷材时，按照一下步骤进行：
步骤一、按配比将107硅橡胶、正硅酸乙酯、羟基硅油、二月桂酸二丁基锡、氨基官能团硅烷和阻根剂混合，在80～120r/min的搅拌速度下搅拌至混合均匀；
步骤二、加入微胶囊在10～30r/min的搅拌速度下搅拌至混合均匀，得到有机硅预聚体；
步骤三、将有机硅预聚体涂覆在高分子层的表面，经真空脱泡、浸渍玻璃纤维后再涂覆一层机硅预聚体，再次真空脱泡、浸渍玻璃纤维后，在室温下静置固化；
步骤四、卷绕、传递、包装。
实施例1
取100份107硅橡胶，1份正硅酸乙酯，1份羟基硅油，0.1份二月桂酸二丁基锡(DBTDL)，0.1份氨基官能团硅烷(KH550)，0.1％的阻根剂进行初混合，搅拌速度为80r/min，使各组分混合均匀，再将10份的微胶囊加入上述体系，在10r/min的速度进行搅拌，得到有机硅预聚体，然后涂覆在改性高分子层表面，真空脱泡，浸渍玻璃纤维，再涂覆一层上述有机硅预聚体，真空脱泡，静置室温固化，经过卷绕辊对卷材进行卷绕、传递、包装。其中高分子层采用厚度100μm的聚丙烯膜，进行电晕处理并接枝甲基丙烯酸缩水甘油酯，接枝率为5％。
