Abstract

탄성실리콘폼(elastomeric silicone foams)의 제조에 있어서 오르가노폴리실록산(1), 유화제(2), 물(3) 및 점도부여제(4)를 구성하는 수용성에멀젼을 기재로한 새로운 발포제조성물(a)에 대한 것이다.
이 새로운 발포제조성물은 경화시켜 탄성실리콘폼을 얻을 수 있고 발포제조성물(a), 디오르가노폴리실록산(b), 가교제(c) 및 필요할경우 가교촉매(d) 및 선택적인 필러(e)를 구성하는 조성물에 사용된다.
고온경화에 의한 탄성실리콘폼의 제조는 발포제조성물(a), 디오르가노폴리실록산(b), 가교제(c) 및 필요할경우 가교촉매(d)와 선택적인 필러(e) 및 선택적인 또다른 물질을 서로 혼합시켜, 그 얻어진 혼합물을 온도 100~250℃에서 동시포밍으로 경화시켜 실시하여 탄성실리콘폼을 얻는다.
