Abstract
다음 일반식으로 표현되는, 향상된 용해도 특성을 갖는 에폭시 수지용 경화제.A hardening | curing agent for epoxy resins with improved solubility characteristics represented by the following general formula.
상기 일반식에서 R은 -C6H4X, -CH2C6H4X, -CH2CH2C6H4X 또는 CnH2n-1ㅇ고; X는 -H, -CH3, -OCH3, -OH, 또는 -NY2이며, Y는 -H 또는 -CH3이고, n은 1-12임.R is -C 6 H 4 X, -CH 2 C 6 H 4 X, -CH 2 CH 2 C 6 H 4 X or CnH 2n-1 in the general formula; X is -H, -CH 3 , -OCH 3 , -OH, or -NY 2 , Y is -H or -CH 3 and n is 1-12.
그러한 치환 시아노구아니딘들은 여러가지 용매들에 가용성이며, 시아노구아니딘 그 자체에 필요한 바람직하지 못한 용매들의 사용을 필요로 하지 않는다.Such substituted cyanoguanidines are soluble in various solvents and do not require the use of undesirable solvents required for cyanoguanidine itself.
Description
본 발명은 일반적으로 에폭시 수지들의경화, 좀 더 상세히는, 에폭시 수지물과 함께 사용되는 경화제물의 개선에 관한 것이다. 디시아느디아미드(시아노구아니딘으로도 정하여짐)는 에폭시 수지용 경화제로서 잘 알려져 있으며, 본 발명은 그를 대체하는 개선된 경화제를 제공하고자 하는 것이다.The present invention generally relates to the curing of epoxy resins and, more particularly, to the improvement of hardeners used with epoxy resins. Dicyandiamide (also defined as cyanoguanidine) is well known as a curing agent for epoxy resins, and the present invention seeks to provide improved curing agents to replace them.
디시아노디아미드는 에폭시 수지용 경화제로서 널리 알려져 있으나, 또한 중대한 결점을 갖는 것으로 알려져 있다. 그것은 대부분의 적용들에서 물과 함께 사용할 수 없거나 또는 디메틸포름아미드 등과 같이 비교적 비싸거나 환경학적으로 바람직하지 않기 때문에 좋지 않은 응매들 내에서만 응해될 수 있다.Dicyanodiamide is widely known as a curing agent for epoxy resins, but is also known to have serious drawbacks. It may not be used with water in most applications or may only coagulate in poor solvents because it is relatively expensive or environmentally undesirable such as dimethylformamide or the like.
미국특허 No. 3,552, 165에는 이미다졸의 금속염과 다른 화합물(디시아노디아미드일 수 있음)을 조합시킨 경화제가 개시되어 있다. 이 경화제를 상온에서 장기간 동안 저장될 수 있으나 노은 온도에서 경화될 수 있는 일부 에폭시 조성물에 사용된다.U.S. Patent No. 3,552, 165 disclose hardeners in which a metal salt of imidazole is combined with another compound, which may be dicyanodiamide. This curing agent is used in some epoxy compositions that can be stored for long periods at room temperature but can be cured at furnace temperatures.
디시아노디아미드의 제2화합물의 다른 조합이 미국특허 No. 4,311,753에 밝혀져 있는데, 여기서는 디시아노디아미드가 테트라알킬 구아니딘과 함께 연합되어 디-및 테트라-작용성 에폭시드들(di-and tetra-functional epoxides)의 혼합물들에 대한 경화제를 제공한다.Other combinations of the second compound of dicyanodiamide are described in US Pat. 4,311,753, wherein dicyanodiamide is associated with tetraalkyl guanidine to provide a curing agent for mixtures of di-and tetra-functional epoxides.
미국 특허 No. 4581, 422에 개시된 바와같이, 디시아노디아미드와 포름알데히드 및 아민 중결된 폴리에테르의 반응 산들이 에폭시 수지를 경화시키는데 사용될 수 있다. 그러한 반응 산물은 치환 시아노구아니딘(substituted cyanoguanidine)이나, 추후 설명되듯이, 아민 종결된 폴리에테르 및 포름알데히드로부터의 메틸렌기의 점가에 의하여 그것은 본 발명의 것들과는 상이하다.U.S. Patent No. As disclosed in 4581, 422, reactive acids of dicyanodiamide with formaldehyde and amine terminated polyethers can be used to cure the epoxy resin. Such reaction products are substituted cyanoguanidines, but as explained later, by the addition of amine terminated polyethers and methylene groups from formaldehyde, they differ from those of the present invention.
다소 유사한 조성물이 일본 특허공고 61-207425호에 개시되어 있는데, 여기서는 시아노구아니딘 화합물들, 폴리에테르아민들, 및 구아나이드 화합물들을 조합한 에폭시 경화제를 사용한다.A somewhat similar composition is disclosed in Japanese Patent Publication No. 61-207425, which uses an epoxy curing agent combining cyanoguanidine compounds, polyetheramines, and guanide compounds.
최근 공고된 두가지 유럽 특허 출원들이 소정의 치환 시아노구아니딘들을 에폭시용 경화제들로서 유용한 것으로 언급하고 있다 EP 306,451에서는 지한 3-시아노구아니딘물의 올리고머들이 걸트되었다. 그러한 화합물들은 모노 이소시아네이트를 디이소시아네이트와 함께 반응시켜 올리고머를 형성한 다음 시안아미드와 함께 반응시켜 다음 일반식을 갖는 화합물들을 형성함에 의하여 산출된다.Two recently published European patent applications refer to certain substituted cyanoguanidines as useful as curing agents for epoxy. In EP 306,451 oligomers of the 3-cyanoguanidine described are listed. Such compounds are produced by reacting mono isocyanate with diisocyanate to form oligomers followed by cyanamide to form compounds having the following general formula.
