国外先进环氧树脂企业特别重视环氧树脂与固化剂的配套研究开发与生产经营,每一种树脂都有与之配套的固化剂,即能同时向用户提供环氧树脂、固化剂和配方技术。而我们绝大多数厂家仍将环氧树脂仅视为一种产品,而对与之配套的固化剂重视不够,品种不全,品种牌号少,质量差而又不稳定,初级、低档次固化剂还占主导地位,品种结构不合理,聚酰胺固化剂和改性芳香胺固化剂品种太少,产量 相似文献

环氧树脂化工产品是目前化工产业竞争较为激烈的一种生产行业,也是当前化工原料中不可缺少的产品。目前国外通用型的环氧树脂一般是指828、331、850等基础树脂,而国内则以6101、e-44为主。国外已将专门用途的环氧树脂与固化剂、活性稀释剂、助剂、填料等配套成专用的“环氧系统”,统称为:“epoxy system”。而国内“环氧系统”尚未形成气候,仍处在“epoxy resin”阶段,这是两个不同的概念。正是基于以上的分析,笔者以为环氧树脂必需进行产品结构调整以适应与国际接轨的形势需要。 相似文献
