本发明粘合剂中使用的催化剂用于引发或促进基础聚合物与交联剂进行缩 合反应; 优选的催化剂选自月桂酸二丁基锡、 正硅酸乙酯 /二丁基锡、 Sn(OCOC8H17)2、 PhNH2和 Bu H的一种或几种。
本发明防火板的粘合剂层中使用的填料包括补强填料和增强填料, 优选的 补强填料为二氧化硅、 碳黑或二氧化钛, 优选的增强填料为硅藻土、 石英粉、 三氧化二铁或重质碳酸钙。
在实际使用中, 上述粘合剂可以以单组分结构来使用, 也可以以双组分结 构使用, 即将基础聚合物和填料作为组分 A, 而将交联剂和催化剂等成分作为 组分 B , 组分 A和组分 B在进行粘合前进行混合。
为提高粘合剂层的粘合性能,上述的粘合剂在使用时可进一步包括稀释剂、 增稠剂和偶联剂。
根据本发明的另一方面, 提供制造本发明新型防火板的方法, 包括下述步 骤:
1. 混料:
对于本发明的单组分粘合剂, 先将胶料(基础聚合物)、 填料等混合均匀, 进行干燥处理后, 加入交联体系混合均匀, 装管密封备用。 对于本发明的双组 分粘合剂, 则先将 A组分和 B组分分别混合均匀, 在涂布时将 A、 B两个组 分按比例(如 A:B=100:3.5 ~ 4.0 )均匀混合。 混合可在混料器内或原包装桶内 进行。 如用量少, 可在干净和干燥的杯子或小桶内混合, 用人工或机械搅拌混 合均可。
2. 硫化:
一般在室温(23 ~ 25 °C ) 下硫化, 提高温度可以加快硫化速度, 但温度不 要超过 90°C , 以免胶的粘度增加太大, 妨碍将胶均勾的涂布到欲粘合的材料 上。 硫化速度还与湿度有关, 暴露在高湿度的空气中可加快硫化速度。
3. 稠度的调整:
为适应工艺要求, 需要对胶料增稠时, 可加入一些增稠剂, 如碳酸钩、 硅 藻土、石英粉等; 当需要降低胶料粘度时, 可加入一些相容性好或同一结构类 型的低分子量硅油作稀释剂。
4. 表面处理:
有些基材的比表面能很小, 很难与其它基材粘合。 此时应对基材表面进行 除油污等清洁及干燥处理,若为橡胶还需要用砂子将表面打毛。为了提高粘合 剂对基材的粘合强度, 可在基材表面上涂上底涂剂。 大多数底涂剂是由反应活 性较高的硅烷偶联剂或其他有机金属化合物的有机溶剂稀释液组成,在潮湿空 气中可以水解缩合成树脂状活性层, 它与基材表面起着键合与偶联剂作用,从 而提高粘合性。
5. 粘合:
在云母板上均匀地涂上本发明的粘合剂 , 最后将经上述处理的基材置于云 母板上并送入平板硫化机中,在 0.1 ~ 0.5Mpa的压力于 23 ~ 90°C下处理 1 ~ 24 小时即得本发明的防火板。
在粘合过程中, 根据需要, 硫化和粘合的步骤可在同一步操作中完成。 附图的简要说明
