Description
技术领域
本发明公开了一种环氧树脂胶的工艺生产配方及其制备方法,属于环氧树脂胶技术领域。
背景技术
环氧树脂是一种高分子聚合物,分子式为(C11H12O3)n,是指分子中含有两个以上环氧基团的一类聚合物的总称。它是环氧氯丙烷与双酚A或多元醇的缩聚产物。由于环氧基的化学活性,可用多种含有活泼氢的化合物使其开环,固化交联生成网状结构,因此它是一种热固性树脂。。
环氧树脂胶一般是指以环氧树脂为主体所制得的胶粘剂,环氧树脂胶一般还需要加入环氧树脂固化剂使其固化,环氧树脂胶应用十分广泛,可粘接各种金属及合金,陶瓷、玻璃、木材、纸板、塑料、混凝土、石材、竹材等非金属材料,亦可进行金属与非金属材料间的粘接。对未经处理的聚乙烯、聚丙烯、聚四氟乙烯、聚苯乙烯、聚氯乙烯等塑料则无粘接性,对于橡胶、皮革、织物等软质材料的粘接能力也很差。除了粘接之外,环氧树脂胶还能用于浇铸、密封、嵌缝、堵漏、防腐、绝缘、导电、固定、加固、修补等,广泛用于航空、航天、车船、铁路、机械、兵器、化工、轻工、水利、电子电气、建筑、医疗、文体用品、工艺美术、日常生活等领域。
现有环氧树脂胶扩散性强,流动性能差,尤其是当该树脂胶呈水滴状时,容易与其他物体黏着,使得树脂胶在移动路径上,产生明显的油渍痕迹。
针对上述问题,制定本工艺方法,不会影响使用胶水的外观及清洁,且对下一步工艺施工作业不造成麻烦,调整环氧树脂的中的成分以及调整各个成分中的配比,在不影响胶水其他的性能,减少现有环氧树脂胶的扩散性,使得胶水固化后不析出油渍,不影响胶水电性能,同时也便于清洁。
发明内容
本发明的目的是为了解决上述不足而提供一种环氧树脂胶的工艺生产配方及其制备方法。
一种环氧树脂胶的工艺生产配方,配方组成按重量计包括:100重量份E-44环氧树脂、8-12重量份固化剂、5-10重量份增韧剂、50-70重量份稀释剂、7-12重量份阻燃剂、5-10重量份有机锡、3-10重量份刚玉粉和5-9重量份瓷粉;
作为优选,所使用的固化剂为脂肪胺、聚酰胺和多异氰酸酯的混合物,且固化剂中脂肪胺、聚酰胺和多异氰酸酯的混合比例为3:3:4。
