Abstract
본 발명은 미리 3급 아민 등의 반응 개시제를 혼합할 수 있기 때문에 2액성으로 사용할 수 있고, 점도 및 사용가능 시간을 임의로 조정할 수 있는 저악취 폴리머캅탄계 에폭시수지 경화제를 제공하는 것에 관한 것이다.The present invention relates to providing a low-odor polymercaptan-based epoxy resin curing agent which can be used in two-liquid form and can optionally adjust the viscosity and the usable time since reaction initiators such as tertiary amines can be mixed in advance.
또한, 본 발명은 에폭시수지에 대한 경화제의 첨가량을 에폭시 당량과 활성수소 당량에서 계산되는 경화제 이론 첨가량의 0.8~0.5로 사용함으로써, 내수성, 열열화성, 작업성, 경제성 등의 특성에 뛰어난 에폭시수지를 조성물을 제공하는 것에 관한 것이다.In addition, the present invention by using the addition amount of the curing agent to the epoxy resin of 0.8 ~ 0.5 of the theoretical addition amount of the curing agent calculated from the epoxy equivalent and the active hydrogen equivalent, the epoxy resin excellent in properties such as water resistance, thermal deterioration, workability, economic efficiency, etc. The present invention relates to providing a composition.
본 발명의 에폭시수지 경화제는 알킬디머캅탄, 폴리글리콜디머캅탄, 디머캅토폴리에틸설파이드 단독 또는 혼합물에 대하여 1분자중에 1개 이상의 에폭시기 및 방향 고리를 가진 에폭시수지를 단독으로 또는 혼합하여 소량의 3급 아민 촉매의 존재하에서 반응시켜서 저악취의 폴리티올 반응물을 수득하고, 이 폴리티올 반응물에 또 3급 아민 및 또는 폴리아민등의 1분자중에 아민활성수소를 2개 이상 가진 아민류를 적량 첨가함으로써 수득하는 머캅탄계 에폭시수지 경화제이다.The epoxy resin curing agent of the present invention is a small amount of tertiary by mixing one or more epoxy resins having one or more epoxy groups and aromatic rings in one molecule with respect to alkyl dimercaptan, polyglycol dimercaptan, dimercaptopolyethylsulfide alone or mixture. A mercap obtained by reacting in the presence of an amine catalyst to obtain a low-odor polythiol reactant, and adding appropriate amounts of amines having two or more amine-activated hydrogens in one molecule such as tertiary amine and / or polyamine to the polythiol reactant. Carbon-based epoxy resin hardener.
또한, 본 발명의 에폭시수지 조성물은 에폭시수지 또는 그 개질품의 에폭시 당량과, 본 경화제의 활성수소 당량으로부터 산출한 본 경화제의 이론 첨가량이 0.8~0.5배인 조성물이다.In addition, the epoxy resin composition of this invention is a composition whose theoretical addition amount of this hardening | curing agent computed from the epoxy equivalent of epoxy resin or its modified product, and the active hydrogen equivalent of this hardening | curing agent is 0.8-0.5 times.
