Abstract
실리콘 고무 중전제용 침강실리카의 제조방법에 관한 것으로서, 제일 먼저 반응기에 물을 투입하고 소정온도로 승온시킨 후 소정밀도의 규산소다와 황산을 동시에 투입하되 80~95℃의 온도범위에서 pH 9~10로 조절하여 90~120분만 반응시킴으로서 생산수율이 좋고, 고무에 충전시 백탁현상과 황변현상이 나타나지 않고 분산성 및 인장강도가 높고, 가스성 및 선형 압축율이 우수한 침강실리카를 얻는 침강실리카 제조방법이다.It relates to a method for producing precipitated silica for silicon rubber heavy-agent. First of all, water is added to the reactor and the temperature is raised to a predetermined temperature. Then, sodium silicate and sulfuric acid having a predetermined density are simultaneously introduced, and the pH is 9 to 10 at a temperature range of 80 to 95 ° C. It is a method of producing precipitated silica that obtains precipitated silica with high dispersibility and tensile strength and excellent gaseous and linear compressibility without appearing turbidity and yellowing when filled with rubber. .
