Description

一种二阶环氧粘层油、制备方法及其应用方法 技术领域
本发明涉及路桥铺装用粘结剂，尤其涉及二阶环氧粘层油、制备方法及其应用方法。
背景技术
钢桥面铺装、混凝土桥面铺装及隧道铺装等路桥铺装领域的(防水)粘结层存在两个问题，一是如何增加(防水)粘结层与上层铺装间的粘结性能；二是如何减少施工过程中摊铺机、运料车等对(防水)粘结层的破坏。这两个问题的解决往往存在矛盾：增加粘结性能往往需要(防水)粘结层在上层铺装施工时仍处于未固化状态，但施工机械的粘轮现象会破坏(防水)粘结层的完整性；而等到(防水)粘结层完全固化时，虽然施工机械粘轮问题得到解决，但固化后的(防水)粘结层与上层铺装间的粘结性能几乎丧失殆尽。
上述问题在钢桥面铺装领域尤其突出，针对上述行业技术难题，钢桥面铺装行业先后产生以下几种解决方案：方案一，采用具有热塑性的沥青(防水)粘结层，包括溶剂型沥青、热喷沥青及不粘轮乳化沥青。该方案主要配合双层SMA钢桥面铺装结构进行实施，并在海沧大桥、鹅公岩长江大桥等国内早期建设的钢桥面铺装中应用，但总体应用效果不佳。虽然沥青(防水)粘结层在一定程度上解决了施工机械粘轮问题，但沥青热塑性的本质并不满足钢桥面铺装在高温条件下的粘结及抗剪需求；方案二，采用具有热固性的环氧沥青(防水)粘结层。该方案主要配合双层环氧沥青钢桥面铺装结构进行实施，并在南京长江二桥、润扬长江大桥、阳逻长江大桥等钢桥面铺装中应用，总体应用效果好坏参半。为防止上层铺装施工过程中对未固化的环氧沥青(防水)粘结层破坏，专门开发了一套侧向喂料系统，但摊铺机履带仍不可避免的会对未固化的环氧沥青(防水)粘结层产生破坏；方案三，采用具有多层结构的丙烯酸(酯)防水粘结层。该方案主要配合浇注式沥青混合料进行施工，并在香港青马大桥、马鞍山长江大桥、港珠澳大桥等钢桥面铺装用应用，虽然目前总体应用效果较好，但是该方案仅适用于浇注式沥青铺装，且防水粘结层层数多达4层，施工较为复杂；另一方面，由于浇注式沥青高温稳定性较低，其一般仅作为钢桥面铺装下层，丙烯酸(酯)并不适合作为粘结层，故上下 层铺装间的粘结问题仍得不到解决。
有鉴于上述现有的钢桥面铺装、混凝土桥面铺装及隧道铺装等路桥铺装领域的(防水)粘结层存在的缺陷，本发明人基于从事此类产品设计制造多年丰富的实务经验及专业知识，并配合学理的运用，积极加以研究创新，以期创设一种路桥铺装用二阶环氧粘层油及其制备方法，解决钢桥面铺装、混凝土桥面铺装及隧道铺装等路桥铺装领域粘结层粘轮与粘结间的矛盾，使其更具有实用性。
发明内容
本发明的主要目的之一为提供一种二阶环氧粘层油，通过优化粘层油的组分，使得其既能够满足与铺装层之间的粘结性，又能够减少施工过程中对粘结层的破坏。
为了达到上述目的，本发明所采用的技术方案是：
一种二阶环氧粘层油，其中二阶环氧粘层油由主剂A和固化剂B组成，主剂A和固化剂B的重量比为1～3:1；主剂A包括80～90份线型酚醛多缩水甘油醚，10～20份单官能度活性稀释剂，1～3份环氧基硅烷偶联剂；固化剂B包括70～90份线型双官能度仲胺固化剂，10～30份高熔点潜伏型固化剂和1～5份防沉剂。本发明提出的二阶环氧粘层油具有两阶段固化的特性：其中一阶段采用常温固化，固化物指压干且呈热塑性状态，避免粘轮现象，二阶段在100～180℃下进一步固化，固化物呈热固性状态，保证粘结性，采用二阶段固化的模式可以解决路桥领域铺装粘结层粘轮与粘结性之间的矛盾。
优选的，线型酚醛多缩水甘油醚采用苯酚型酚醛环氧树脂、邻甲酚型环氧树脂以及双酚F型环氧树脂中的一种或多种。采用这几种材料的原因是这些材料作为环氧树脂的主体部分，每种材料均有一定的环氧当量值，本发明专利中的二阶段固化剂的用量是根据固化剂的胺当量×环氧当量值计算而得到的，换而言之，这些环氧树脂材料与本发明的固化剂相匹配。
优选的，单官能度活性稀释剂选用丁基缩水甘油醚、苯基缩水甘油醚、辛基缩水甘油醚、碳八至碳十缩水甘油醚及碳十二至十四缩水甘油醚中一种或多种。线型酚醛多缩水甘油醚为分子中含有两个以上环氧基团的一类聚合物，单官能度活性稀释剂一般是指带有一个环氧基团的低分子化合物，它们具有相似相溶的特点。在线型酚醛多缩水甘油醚中掺入单官能度活性稀释剂，一方面，单官能度活性稀释剂可以直接参与线型酚醛多缩水甘油醚的固化反应，成为二阶环氧粘层油固化物交联网络结构的一部分，对固化产 物的性能没有影响，可适当增加固化体系的韧性；另一方面，单官能度活性稀释剂可以调节二阶粘层油体系的粘度，便于施工。
优选的，硅烷偶联剂为SCA-E87M、SCA-E87E、SCA-E87T、SCA-E87F、SCA-E86M及SCA-E86中的一种或多种。硅烷偶联剂中的烷氧基吸湿后可水解而与钢板层或者环氧沥青层表面形成化学健，提高二阶粘层油的亲和性及抗湿热性，硅烷偶联剂中的其他活性基团亦可与环氧树脂或固化剂反应，提高二阶粘层油粘结性。
优选的，线型双官能度仲胺固化剂由双官能度伯胺固化剂与单环氧化合物接枝改性而来，双官能度伯胺固化剂为己二胺、癸二胺、十二胺及端氨基聚醚中的一种或多种；单环氧化合物为丁基缩水甘油醚、苄基缩水甘油醚、辛基缩水甘油醚及碳十二至十四缩水甘油醚中的一种或多种。采用这些单环氧化合物可使得双官能度伯胺固化剂中的-NH 2基团被部分封端。采用这些线型双官能度仲胺固化剂可使得最终的线型双官能度仲胺固化剂与环氧树脂能够常温固化，固化物成热塑性。
优选的，高熔点潜伏型固化剂为有机酸酯与水合肼经水热反应制得的熔点介于100～180℃的有机酸酰肼，有机酸酯的结构通式为R 1(COOR 2) n，当n＝1时，R 1为苯基或邻羟基苯基，R 2为甲基或乙基；当n＝2时，R 1为亚甲基或亚乙基，R 2为甲基或乙基。
优选的，防沉剂为亲水型气硅、疏水型气硅R974及改性膨润土中的一种或多种。
本发明的主要目的之二为提供一种二阶环氧粘层油的制备方法，通过优化二阶环氧粘层油的制备工艺，调控制备参数，使得最终产品能够满足工程需求，既能够提高与铺装层之间的粘结性，又能够减少施工过程中对粘结层的破坏。
为了达到上述目的，本发明所采用的技术方案是：
二阶环氧粘层油的制备方法，包括以下步骤：
S1.将1～5份(摩尔量)双官能度伯胺固化剂投入到反应釜中，并升温至80℃；将2～10份(摩尔量)单官能度环氧化合物缓慢滴入反应釜内，滴加时间为2h，料温为80℃，搅拌速率为60r/min，得到线型双官能度仲胺固化剂；
S2.将1～5份(摩尔量)水合肼投入到反应釜中，并升温至70℃；将1～5份50％浓度的有机酸酯异丙醇溶液缓慢滴入反应釜内，滴加时间为2h，滴加完成后继续反应5h，料温为70℃，搅拌速率为60r/min，向反应釜内加入适量二甲苯，然后在真空条件下蒸馏二甲苯、水、水合肼及醇的共沸物，得到的有机酸酰肼即为高熔点潜伏型固化剂；
S3.称取线型酚醛多缩水甘油醚、活性稀释剂和环氧基硅烷偶联剂，在60℃下搅拌60min，得到主剂A；
S4.称取线型双官能度仲胺固化剂、高熔点潜伏型固化剂及防沉剂，在50℃下搅拌60min，得到固化剂B；
S5.将主剂A和固化剂B搅拌混合得到二阶环氧粘层油。
本发明的主要目的之三为提供一种二阶环氧粘层油的应用方法，将性能优化后的二阶环氧粘层油应用在钢桥面铺装、混凝土桥面铺装及隧道铺装中，作为路桥铺装用防水粘结层材料，使得桥面层之间具有良好的粘结性，同时又避免了在施工过程中产生的粘轮现象对结构层的破坏，保证工程质量。
为了达到上述目的，本发明所采用的技术方案是：
本发明的二阶环氧粘层油主要应用在钢桥面铺装、混凝土桥面铺装及隧道铺装中，作为路桥铺装用防水粘结层材料，其中二阶环氧粘层油的应用方法，包括以下步骤：
A1.基面清洁：对基面进行清洁处理，提高粘结性，具体可以采用喷砂、抛丸等方法；
A2.喷洒硅烷界面剂形成对清洁基面的增粘改性防腐层：按硅烷偶联剂1～2％、异丙醇85～99％、水0～10％、醋酸0～1.5％的质量比配制硅烷界面剂，然后采用机械喷涂的方式对A1中的清洁基面进行喷洒；针对不同基面采用不同的喷洒量，其中钢板基面的喷洒量为0.1～0.2kg/m 2，混凝土基面的喷洒量为0.2～0.5kg/m 2；
A3.涂布二阶环氧粘层油形成(防水)粘结层：待硅烷界面剂干燥成膜后，采用人工刮涂、滚涂或机械喷涂的方式涂布二阶环氧粘层油，针对不同基面采用不同的涂布量，钢板基面的涂布量为0.4～0.6kg/m 2，混凝土基面的涂布量为0.6～1.0kg/m 2；
A4.一阶段固化：对二阶环氧粘层油进行一阶段养生固化，以指压干为一阶段固化完成标志；
A5.热混合料施工：在经一阶段固化后的二阶环氧粘层油上进行热混合料施工形成保护层或磨耗层，一阶段固化后的二阶环氧粘层可在热混合料的热量下完全熔化；
A6.二阶段固化：利用保护层或磨耗层的余热对二阶环氧粘层进行进一步固化，并形成热固性固化物。
通过上述技术方案，本发明的有益效果是：
1.本发明采用混合型固化剂，其中双官能度仲胺固化剂通过单环氧化合物接枝改性双官能度伯胺固化剂制备得出。单环氧化合物的引入使得双官能度伯胺固化剂中的-NH 2基团被部分封端，得到的双官能度仲胺固化剂一方面可以在常温下实现对环氧粘层油的初固化；另一方面可以降低一阶段固化物的交联密度，使其仍处于热塑性状态，这是保证在一阶段固化完成后，防水粘结层仍为热塑性的主要原因；
2.混合型固化剂的另一重要组分为高熔点潜伏型固化剂，是采用有机酸酯与水合肼经水热反应制备而来的有机酸酰肼。有机酸酰肼的熔点处于100～180℃范围内，因此不参与环氧粘层油的一阶段固化反应；待热混合料作用于经一阶段固化后的环氧粘结层时，高熔点的有机酸酰肼固化剂逐步融化为液体，与受热熔化的经一阶段固化的环氧粘层油发生二阶段固化反应，最终在铺装余热的作用下形成具有热固性的环氧粘结层；
3.本发明针对钢桥面铺装、混凝土桥面铺装及隧道铺装等路桥铺装领域(防水)粘结层存在的粘轮与粘结矛盾，通过复合双官能度仲胺固化剂和高熔点潜伏型固化剂实现具有二阶固化特性环氧粘层油的制备。本发明的环氧粘层油一阶段常温固化，固化物不粘轮，且呈热塑性状态，可在120℃以上完全熔化，二阶段在100～180℃下固化，固化物呈热固性状态，从而确保粘结基面与上层铺装间的粘结效果。
