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(EP)改性氰酸酯树脂(CE),“固化”大有看点。CE/EP改性体系既能形成大量的三嗪环,保留CE固有的性能优点,又能形成高度交联网络,提高材料的力学性能。用EP对CE预聚体进行改性发现,虽然改性树脂的硬度和模量有所降低,但其弯曲强度及拉伸强度比纯CE提高了近1倍多,断裂伸长率增加了近3倍,增韧效果明显。采用乙酰丙酮过渡金属络合物等作为固化剂的CE/EP改性体系,固化剂用量为环氧树脂的0.5%(质量分数)。研究表明,环氧树脂与氰酸酯共固化物的电绝缘性能,  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

Estaing, former French president, Valery Giscard d'Estaing attended Sino-French Economic Seminar held in Shanghai in early April and said that the world center has shifted from the west to the east with many European and US companies entering into Asia, and China has the ability to play an important role in the world stage. Estaing, naming himself"French Confucian", then said in Chinese that a cook-group includes 10 people in ancient Chinese soldier system and the cook is in charge of cooking for them. And people who belong to the same cook are actually "Partners".  相似文献

Looking at the increasingly fierce competition in the world auto market. global automobile manufacturing industry, taking Europe, the U.S. and Japan as representatives, is gradually forming a new type of relationship, mutual cooperation between whole vehicle and parts manufacturers. We can clearly see that auto parts manufacturers have become independent from the whole vehicle manufacturing companies, which means that the former structure of auto industry has greatly changed, and a new relationship,  相似文献
