有机硅玻璃树脂和耐高温有机硅云母黏结剂 我国最早开展有机硅玻璃树脂和高温云母黏结剂是化工部晨光化工研究院的霍长顺,陈汝凤等。在上一世纪70年代末开发成功用一甲基三乙氧基硅烷在酸性催化剂存在下水解缩聚反应制得CTS-103有机硅树脂,俗称“有机硅玻璃树脂”。该树脂早期用于高级纸张的处理,以及金属表面的涂覆保护,也可用于云母片或云母粉的黏结。1980年上海树脂厂方三华、薛志庆、李燕声分别采用......
2020-02-19超疏水表面(涂层)在减阻、节能、防冰以及防生物淤积等应用领域有着不可替代的作用。近来,人们已经发展了诸多自下而上或是自上而下的制备策略,用以构筑具有低表面能和粗糙表面结构的功能性超疏水涂层。但是,微纳结构表面构筑过程的复杂性以及微纳粗糙结构易磨损特点使得超疏水涂层在制备成本和使用寿命方面受到极大地制约。发展简便策略实现具有高耐磨或易修复、可再生的超疏水表面的的功能涂层是该领域的重要发展方向。 ......
2020-02-19环氧涂料由于其极佳的粘结强度、耐化学品性能以及优异的物理机械性能,可提供极好的防腐性能。同时由于环氧树脂的耐紫外光老化性能差的问题,使其在户外的应用场合中会由于阳光的长时间曝晒而产生漆膜的损伤,出现开裂、粉化的问题。 有一些有机硅氨基树脂由于其良好的耐候性能,且可以与环氧树脂交联固化,可以赋予环氧涂料独特的耐候性能。 在室温条件下即可固化 &nbs......
2020-02-19硅树脂(silicone)其实从严格意义并不是一种特定的材料,而是一种增强剂和致能冲剂。硅是地球上数量最充沛的金属元素之一,而硅树脂则是以硅元素作为关键成分的化合物,讲到这里大家一定会想到硅胶是不是就是硅树脂呢?其实并不然~硅胶是硅树脂和橡胶的一个调配的分类而已,只是平时生活中我们会接触的比较多。硅树脂可以通过不同的调配去改善从墨水,颜料到织物等等物品非常多的功能。所以硅树脂其实拥有极度多样性的特......
