Abstract

본 발명은 초고강도 시멘트 폴리머 복합 재료의 제조 방법에 관한 것으로 포틀랜드 시멘트와 미분쇄 슬래그, 실리카 퓸, 무수 석고, 열가소성 수지, 골재, 강섬유로 구성되어 있는 초고강도 시멘트 복합 재료의 조성물과 이를 혼합한 시멘트 혼합물을 온도 60 내지 90℃의 수중에서 열수 중에서 양생하고, 150 내지 200℃의 온도에서 가열 양생시켜 초고강도 발현 시멘트 폴리머 복합 재료를 제조하는 방법이다.The present invention relates to a method for producing an ultrahigh strength cement polymer composite material, which comprises a composition of ultra high strength cement composite material consisting of Portland cement and fine pulverized slag, silica fume, anhydrous gypsum, thermoplastic resin, aggregate and steel fiber, The mixture is cured in hot water at a temperature of 60 to 90 占 폚 in water and heated and cured at a temperature of 150 to 200 占 폚 to produce an ultrahigh strength cement polymer composite material.

본 발명의 방법은 열경화성 수지를 첨가하여 연화점 이상의 온도에서 가열 처리함으로써 수지가 연화되어 내부 공극으로 침투해 공극을 줄이고, 가열 양생에 의해 생기는 내부의 미세 크랙으로 침투해 피막을 형성하여 인성 중진 효과를 볼 수 있어, 폴리머 함침 조작과 같은 복잡한 제조 공정 없이 폴리머 복합 초고강도 시멘트 복합 재료의 제조가 가능하다는데 특징이 있다.The method of the present invention is a method in which a thermosetting resin is added and heat-treated at a temperature higher than the softening point to soften the resin so that the resin penetrates into the inner cavity to reduce voids and permeates into the inner fine cracks generated by heating curing to form a film, And it is possible to manufacture a polymer composite ultrahigh strength cement composite material without a complicated manufacturing process such as a polymer impregnation operation.
