Abstract

알콕시실란 및(또는) 그의 부분 가수분해 축합물인 알콕시실록산과, 1분자내에 적어도 2개의 히드록실기를 갖는 폴리에스테르 수지를 혼합하고, 촉매 존재하에서 가수분해 및 중축합 반응을 수행함으로써, 폴리에스테르 변성 실리콘 수지를 제조한다.Polyester modification by mixing an alkoxysilane and / or a partial hydrolysis condensate thereof with an alkoxysiloxane and a polyester resin having at least two hydroxyl groups in one molecule, and performing a hydrolysis and polycondensation reaction in the presence of a catalyst A silicone resin is prepared.

가수분해, 중축합 및 변성의 각 공정이 연속된 한 단계의 반응으로 수행되기 때문에, 종래의 방법에 비해서 적은 수의 공정으로 폴리에스테르 변성 실리콘 수지를 수득할 수 있다. 또한, 수득되는 수지는 경화성이 우수하고, 납 촉매 등의 안정성에 문제가 있는 경화 촉매를 사용하지 않고 온화한 경화 조건하에서도 기계적 특성이 우수한 경화 도막을 형성할 수 있다.Since each process of hydrolysis, polycondensation and modification is carried out in one continuous reaction, it is possible to obtain a polyester-modified silicone resin in a smaller number of processes than the conventional method. In addition, the obtained resin is excellent in curability and can form a cured coating film excellent in mechanical properties even under mild curing conditions without using a curing catalyst having a problem in stability such as a lead catalyst.
