Description

建筑材料用的高效快干型硬化胶
技术领域
本发明涉及硬化胶，尤其涉及建筑材料用的高效快干型硬化胶。
背景技术
硬化胶的具有很高的粘接强度，但是也存在一些不足，如固化时间长、手工混合不匀造成固化不良、气味比较重等等不足，目前有一套快速点胶系统可以解决，这个系统在国外已经普及了，在国内还没有普及，大部分人使用的时候采用传统的方法进行点胶涂胶，具有高粘接强度、高硬度、高抗化学性外，还具有抗黄变效应，即使在垂直面或吊顶天花板上涂刮也不流挂，干固适中、安全环保。
传统硬化胶混合比较麻烦，需要将硬化剂与本胶分别放在不同容器内，使用时进行混合，混合效果较差，不能灵活控制本胶与硬化剂之间的混合比例，造成混合后的硬化胶粘性较差，固化不良，实用性不强。
发明内容
本发明克服了现有技术的不足，提供建筑材料用的高效快干型硬化胶。
为达到上述目的，本发明采用的一种技术方案为：建筑材料用的高效快干型硬化胶，包括：至少一个微囊，所述微囊为中空结构，所述微囊内部含有硬化剂；本胶，所述微囊可投放到本胶中，当所述微囊壁通过高频线圈加热时，所述微囊壁发生微爆，所述硬化剂与所述本胶混合。
本发明一个较佳实施例中，所述微囊壁上至少一个金属颗粒，当金属颗粒为复数个时，复数个所述金属颗粒间隔设置在所述微囊壁的外侧。
本发明一个较佳实施例中，所述金属颗粒在高频线圈产生的磁场内产生涡流，进而加热所述金属颗粒。
本发明一个较佳实施例中，所述硬化剂内还添加有填料。
本发明一个较佳实施例中，所述硬化剂配比为四氢邻苯二甲酸酐5％-20％、甲基四氢邻苯二甲酸酐15％-30％、氨乙基哌嗪1-2％、填料5-55％。
本发明一个较佳实施例中，所述本胶的配比为双酚A型环氧树脂30-45％、缩水甘油醚氧丙基三甲氧基硅烷0.5-1％、硅酸钙30-42％、碳酸钙5-15％、二氧化碳1-5％。
本发明采用的另一种技术方案为：一种如权利要求1所述的硬化胶的使用方法，其特征在于，包括以下步骤：
(1)将硬化剂放入微囊内，然后将微囊投入本胶内；
(2)将步骤(1)中投入本胶内的微囊通过高频线圈通电产生交变磁场；
(3)微囊壁上的金属颗粒在磁场内产生涡流进行加热，微囊发生微爆；
(4)微囊内部的硬化剂在微爆过程中释放，从而硬化剂与本胶进行混合。
本发明一个较佳实施例中，步骤(1)中的所述微囊尺寸为1-250微米。
本发明一个较佳实施例中，步骤(3)中微囊壁上的金属颗粒能够是不同电阻率的金属。
本发明解决了背景技术中存在的缺陷，本发明具备以下有益效果：
(1)通过微囊使硬化剂与本胶能够放在同一容器内，在需要使用硬化胶时，只需通过高频线圈通电使微囊爆裂，硬化剂流出，与本胶进行混合，使用比较方便，且能够提高硬化胶的使用效率，缩短建筑施工时间。
(2)硬化胶为环氧树脂胶黏剂，具有快干特性，本胶与硬化剂混合后，25度时5分钟即干透，温度越高干透时间越短，可以粘结塑料与塑料、塑料与金属、金属与金属，粘结后剥离需要刀具或热熔分离，粘结效果较好。
(3)环氧树脂胶具有高粘接强度、高硬度还具有抗黄变效应，干固适中，安全环保。
(4)通过高频线圈通电产生交变磁场，进行控制微囊的爆裂，使用灵活性较高。
