Polymer additives containing polyfunctional phosphoric acid groups and method thereof
The present invention relates to a multifunctional phosphate-based polymer additive manufactured by causing phosphorylation of polyether containing amino groups and two or more hydroxyl groups at terminal ends. According to the present invention, when the multifunctional phosphate-based polymer additive is mixed with a polycarboxylic acid-based admixture during the manufacture of concrete, it is possible to manufacture an admixture for concrete, which reduces bleeding, solves problems of workability and production efficiency reduction caused by increased viscosity of concrete, and exhibits excellent effects in maintaining workability and fluidity for a long time by reducing slump loss.
본 발명은 아미노기를 포함하며 말단에 두 개 이상의 히드록시기를 함유하는 폴리에테르에 인산화 반응시켜 제조된 다관능 인산계 고분자 첨가제로서, 콘크리트 제조시 폴리카르본산계 혼화제와 혼합하여 사용하면 블리딩 발생이 적고, 콘크리트의 점성이 증가하여 발생하는 작업성 및 생산효율 저하 문제를 해결하고, 슬럼프 로스가 적어 장시간 작업성과 유동성 유지에 우수한 효과를 발현할 수 있는 콘크리트용 혼화제를 제조할 수 있다.
