An epoxy resin composition comprising a blend of:
(a) at least one condensed polynucleararomatic epoxy resin derived from 2,6-dihydroxynaphthalene, 2,6-dihydroxyanthracene or 2,7-dihydroxyphenanthrene and (b) as curing agent, at least one polyhydric phenolic resin curing agent derived from at least one polyhydric phenolic compound having at least two phenolic hydroxyl groups which are attached to adjacent positions on an aromatic ring like catechol or dihydroxynaphthalenes, as essential components.
The epoxy resin compositions according to the invention have in the cured state high heat resistance, i.e., an excellent strength at high temperature, and are not brittle at ambient temperature. They can be used as an adhesive, casting composition, encapsulating composition, moulding composition, and in the preparation of laminates.
一种环氧树脂组合物,包括以下物质的混合物
(a) 至少一种缩合多核芳香族环氧树脂,由 2,6-二羟基萘、2,6-二羟基蒽或 2,7-二羟基菲衍生而来;(b) 作为固化剂,至少一种多氢酚醛树脂固化剂,由至少一种多氢酚类化合物衍生而来,这种多氢酚类化合物具有至少两个酚羟基,这两个酚羟基连接在邻苯二酚或二羟基萘等芳香环的相邻位置上。
根据本发明的环氧树脂组合物在固化状态下具有很高的耐热性,即在高温下具有很好的强度,并且在环境温度下不会变脆。它们可用作粘合剂、浇铸组合物、封装组合物、模塑组合物以及层压板的制备。
