Description

悬拼架桥结构胶
技术领域
本发明涉及悬拼架桥工程材料领域，尤其涉及一种用于桥梁预制节段拼装的悬拼架桥结构胶。
背景技术
悬拼架桥结构胶，是一种用于采用架桥机进行桥梁预制节段拼装的皎接缝施工的专用胶种。国外进口悬拼架桥结构胶往往价格高昂，增加了生产成本，而国内同类悬拼架桥结构胶普遍存在填料过多，易分层离析，流淌现象，而且材料韧性不足，既浪费结构胶原料，又影响施工环境。
发明内容
本发明的目的在于克服现有技术中的不足，提供一种悬拼架桥结构胶。
本发明是通过以下技术方案实现的：一种悬拼架桥结构胶，由甲组分和乙组分混合调制而成，所述甲组分由下述重量份数配比的原料制成：双酚A型环氧树脂100份，增韧剂5-10份，活性稀释剂3-8份，填料50-100份；所述乙组分由下述重量份数配比的原料制成：复配固化剂35-55份，促进剂1-3份，偶联剂1-4份，触变剂3-5份，填料30-50份。
优选地，所述甲组分与乙组分按照质量比为3:1的比例进行调
优选地，所述双酚A型环氧树脂由双酚A型环氧树脂E-44和双酚A型环氧树脂E-51按照质量比为2:1的比例均匀混合而成。
优选地，所述增韧剂为奇士增韧剂。
优选地，所述填料由粒度为400目的硅微粉组成。
优选地，所述活性稀释剂为苄基缩水甘油醚。
优选地，所述复配固化剂为酯环胺和低分子量聚酰胺复配而成。
优选地，所述促进剂为DMP-30。
优选地，所述偶联剂为KH-550硅烷偶联剂。
优选地，所述触变剂为白炭黑。
本发明的有益效果在于：本发明提供的悬拼架桥结构胶具有施工性能好、不分层、不离析、不流淌的特点，明显节省用胶量，耐酸碱介质侵蚀，在常温下固化，不含挥发份，无毒无害为环保型结构胶，粘结强度高，具有良好的韧性和抗冲击能力。
本发明选用复配双酚A型环氧树脂作为悬拼架桥结构胶的主剂，使得这种结构胶的粘度和粘结强度都得到保证，增韧剂聚合物主链分子中含有活性基团，与环氧树脂中的活性基团反应，形成以CC分散相为"岛"，连结相环氧树脂为"海"的"海岛结构"，达到增韧的目的，使得拉伸剪切强度大幅度提高。
苄基缩水甘油醚作为活性稀释剂，既可以降低高触变悬拼架桥结构胶的黏度，改进其流动度和浸润性，又可因结构中有活性基团而参与环氧树脂固化反应，成为主脂最后形成的网状结构的一部分，克服了因溶剂挥发使胶层粘结力下降的缺陷。
固化剂采用低分子量聚酰胺和酯环胺复配，保留了聚酰胺大配比量,低放热峰,配方范围广,刚性好,强度韧度高等优点，脂环胺和低分子量聚酰胺可以取长补短,既降低了体系的粘度,又保持其持久的发热量促进子分子量聚酰胺固化作用,又能多添加填料,降低成本而性能不下降,提高了耐热性,还可以在-10℃环境中应用,大大扩展了高触变悬拼架桥结构胶的应用范围。
复配固化剂液态化与环氧树脂混合容易，相溶性好，配比不用太严格，还能提高树脂及原、辅料的亲和性，促进剂DMP-30的加入，更进一步提高固化能力，偶联剂是分子两端含有不同性质基团的化合物，两端基可以分别与胶黏剂分子和粘结物结合，起“桥梁”作用，极大地增加了胶层与桥梁节段等基材之间的分子粘结力。
白炭黑作为触变剂的引入，使得悬拼架桥结构胶在外力作用下黏度降低，便于涂抹，静止时黏度增加，胶液不会随意流淌，比同类高触变悬拼架桥结构胶节省用胶量约15％。
