Claims (7)

토올유피치가 주로 평균분자량 600 이상의 에틸렌 옥사이드 단위 또는 3 보다 큰 잔여산가를 가진것의 모노에스텔 또는 모노에텔로 이루어진 폴리알킬렌글리콜로 부분적으로 에스텔화됨을 특징으로 하는 고형입자를 수중에 분산시키기 위한 분산제.Dispersant for dispersing solid particles in water, characterized in that the toric pitch is partially esterified with polyalkylene glycols consisting mainly of monoesters or monoethers having an average molecular weight of 600 or more ethylene oxide units or having a residual acid value of greater than 3. . 제1항에 있어서 토올유피치가 에스텔화전에 공지방법으로 중합하여서됨을 특징으로 하는 분산제.The dispersant according to claim 1, wherein the tol milk pitch is polymerized by a known method before esterification. 제1항에 있어서 부분적으로 에스텔화된 토올로유피치가 폴리아민 또는 알칸올 아민과 반응하여서 됨을 특징으로 하는 분산제.2. Dispersant according to claim 1, characterized in that the partially esterified toluo pitch is reacted with a polyamine or an alkanol amine. 토올유피치를 주로 평균분자량 약 600이상의 에틸렌 옥사이드 단위 또는 이의 모노에스텔이나 모노에텔로 구성된 폴리알킬렌글리콜과 200-285의 온도에서 반응혼합물의 최대산가가 됐어도 그 단위로 감소되도록 오래동안 반응시킴을 특징으로 하는 고형입자를 수중에 분산시키기 위한 분산제의 제조방법.Tolu pitch is reacted with ethylene oxide units of average molecular weight of about 600 or more, or polyalkylene glycols consisting of monoesters or monoethers, at a temperature of 200-285 for a long time to reduce the unit to the maximum acid value. A method for producing a dispersant for dispersing solid particles in water. 분산제가 분산액의 전체중량을 기준으로하여 0.1-5%의 양으로 사용됨을 특징으로 하는 고형입자를 수중에 분산시키기 위한 분산제의 사용방법.A method of using a dispersant for dispersing solid particles in water, characterized in that the dispersant is used in an amount of 0.1-5% based on the total weight of the dispersion. 제5항에 있어서 분산제와 물과의 혼합물은 임의로 알칼리를 첨가하여 PH를 5-10범위이내로 조정하여서됨을 특징으로하는 분산제의 사용방법.The method of using a dispersant according to claim 5, wherein the mixture of the dispersant and water is adjusted by adjusting the pH within the range of 5-10 by optionally adding alkali. 제5항에 있어서 분산액이 크산탄껌과 같은 폴리사카라이드로 이루어짐을 특징으로 하는 분산제의 사용방법.The method of using a dispersant according to claim 5, characterized in that the dispersion consists of polysaccharides such as xanthan gum. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
