COMPOSITION FOR COLORING THE SURFACE OF CONCRETE
A composition for coloring a surface of concrete according to the present invention comprises: 8 wt% of a dye for coloring having the size of 0. 01-1 nm; 45 wt% of a diluent prepared by mixing ion exchange water and ethylene glycol in the weight ratio of 7:3; 7 wt% of methacrylic acid methyl ester; 0.06 wt% of polydimethylsiloxane; 0.5 wt% of fluoropolymer; 6 wt% of colloidal silica; and 25 wt% of modified silicate. According to the present invention, PH of a colored surface is 11 to 13, whereby a concrete surface has the same alkaline as a concrete of alkali component having a Ca[OH]_3 hydroxyl group and the concrete surface is colored by a permeation of the concrete to a depth of 2-3 mm, thereby having a solid surface and aesthetic appearance. Also, the concrete surface is given with a semi-permanent durability and stable implementation of a color, and agglomeration of a material or stains or a color development caused by separating a color or coloring are not occurred.
본 발명에 따른 콘크리트 표면 착색 조성물은, 0.01~1 nm 크기의 착색용 염료 8 wt%, 이온교환수와 에틸렌글리콜을 7:3중량비로 혼합하여 이루어진 희석제 45 wt%, 메타크릴산메틸에스테르 7 wt%, 폴리디메틸실록산 0.06 wt%, 플루오르폴리머 0.5 wt%, 콜로이달 실리카 6 wt%, 변성실리케이트 25 wt%를 포함하여 이루어지는 것을 특징으로 한다. 본 발명에 의하면, 표면 착색된 부분의 PH가 11~13으로서 Ca[OH]수산기를 가진 알칼리 성분의 콘크리트와 같은 알칼리성을 가지며, 2~3mm의 침투에 의한 착색이 이루어져 견고하면서 미려한 콘크리트 표면이 완성된다. 또한, 콘크리트 표면에 반영구적인 내구력이 부여됨과 동시에 안정적인 색상발현이 이루어지며, 제재의 뭉침이나 이색과 착색 시 얼룩이나 발색현상이 발생되지 않는다.
