Description
技术领域
本发明涉及光伏太阳能硅棒切割领域，尤其是涉及一种提高粘接效率的快干铁板胶及其制备方法。
背景技术
目前常规粘铁板胶水是用环氧树脂加入白色颜料、填料和助剂做成A组分，用胺类固化剂加入固化促进剂、红色浆等做成B组分，按1:1比例配比，在25-27℃的固化条件下，粘接切割垫板和铁板，胶凝时间在10-12min，可移动时间14-16min，表干时间20-30min，固化时间120min以上才能上机切割。具有固化速度慢易排泡、流动性好的等特点。
常规胶水同时存在固化慢，不利于铁板的周转等缺点，对于想要提高粘接效率和铁板周转率的需求没法满足，不管是针对手动粘胶或者自动粘胶工艺都一样，无法提高生产效率，产能就受限制。
发明内容
发明目的：为了克服背景技术的不足，本发明第一目的是公开一种提高粘接效率的快干铁板胶；第二目的是公开该快干铁板胶的制备方法。
技术方案：本发明公开的提高粘接效率的快干铁板胶，包括以下质量份的原料：E51环氧树脂58份，环氧活性稀释剂2.5份，碳酸钙73.1份，白色着色剂1.5份，微球发泡剂7份，气相二氧化硅0.1份，聚硫醇固化剂46份，促进剂2份，二乙烯三胺3.5份，稀释剂6份，红色着色剂0.3份。
上述的提高粘接效率的快干铁板胶的制备方法，包括以下步骤：
S1、制备A组分
将E51环氧树脂58份，环氧活性稀释剂2.5份，碳酸钙32.9份，白色着色剂1.5份，微球发泡剂5份，气相二氧化硅0.1份，依次加入搅拌缸，分散搅拌40min，再经过研磨机研磨至细度小于80μm，消泡过滤包装；
S2、制备B组分
聚硫醇固化剂46份，促进剂2份，二乙烯三胺3.5份，碳酸钙40.2份，稀释剂6份，红色着色剂0.3份，微球发泡剂2份，依次加入搅拌缸，分散搅拌40min，再经过研磨机研磨至细度小于80μm，消泡过滤包装；
S3、将A组分和B组分1：1混合。
有益效果：与现有技术相比，本发明的优点为：
1、使用快速固化的聚硫醇和胺类固化剂复配，加入色浆、填料加工成B组分，与A组分按规定比例混合后大幅提高固化速度，减少粘接后的固化时间；在A组分加入可增加附着的活性稀释剂，使混合后的胶水流动性更好，同时增加胶粘剂对塑料板胶层对塑料板和铁板的附着力；在A组分中使用性能稳定的发泡剂，保证好脱胶条件下相应提高胶水的贮存稳定性。
2、采用快速固化的固化剂制作B组分的技术，A和B组分混合后固化时间明显缩短：胶凝时间6min(现有技术10-12min)，可移动时间9min(现有技术14-16min)，表干时间13min(现有技术20-30min)。每60min可粘接6.66刀/人，大大提高粘胶效率，同时可以满足自动线使用；
A组分采用可提高附着力的活性稀释剂，增加胶层与塑料板和铁板的粘接强度，在使用过程中掉板率从3.0％降到0.1％，效果改善明显；
采用稳定性好的发泡剂，使A组分的保质期从60天提高到120天以上。
具体实施方式
下面结合实施例对本发明的技术方案作进一步的说明。
