Acrylic emulsion polymers having repeating units of acrylate and methacrylic esters not only have good adhesion, but also have excellent UV resistance (weather resistance), excellent acid and alkali resistance, and a wide temperature range that can be used, and thus have good cold resistance. Do. As described above, the acrylic emulsion polymer having an acrylic acid ester and a methacrylic acid ester repeating unit exhibits excellent physical properties, but has poor compatibility with the waste tire rubber powder, and thus has poor dispersibility when preparing an elastic coating waterproofing agent. Therefore, in the present invention, as shown in Formula 1, OH, NH 2, C = N, NHCH 2 OH, CH 2 = CH, in the acrylic acid ester (A) and methacrylic acid ester (B) repeat units And a repeating unit (C) having at least one polar group having a terminal selected from the group consisting of COOH as a side chain to further improve dispersibility with the waste tire rubber powder.

상기 표 1을 참조하면, 본 발명에 따른 방수제로 형성된 도막은 인장강도 및 신율이 커서, 방수제가 피착된 기재의 균열이나 팽창 또는 수축현상 등이 발생하더라도 피착된 탄성도막 방수층의 파단현상이나 들뜨는 현상을 방지할 수 있다.Referring to Table 1, the coating film formed of the waterproofing agent according to the present invention has a high tensile strength and elongation, so that even if cracking, expansion, or shrinkage of the substrate on which the waterproofing agent is deposited occurs, the phenomenon of breaking or lifting of the waterproofing layer of the coated elastic coating film occurs. Can be prevented.
본 발명의 수분산성 탄성도막 방수제는 내후성 및 내한성이 우수할 뿐만 아니라 인장강도 및 신장율이 양호하여 방수제가 피착된 기재의 균열이나 팽창 또는 수축현상 등이 발생하더라도 피착된 탄성도막 방수층의 파단현상이나 들뜨는 현상을 방지할 수 있다. 특히 본 발명의 탄성도막 방수제는 수분산성을 가지므로 시공시 용제 증발에 의한 환경파괴 및 화재의 위험을 방지할 수 있으며 습윤상태에서의 시공성이 우수하다. 따라서, 아스팔트 도로공사와 같은 토목공사시 또는 건축물의 지붕이나 옥상 등의 외장공사시 방수제로서 유용하게 사용될 수 있다.The water-dispersible elastic coating waterproofing agent of the present invention not only has excellent weather resistance and cold resistance, but also has good tensile strength and elongation rate, so that even if cracking, expansion or contraction of the substrate on which the waterproofing agent is deposited occurs, breakage of the deposited elastic coating waterproofing layer may occur. The phenomenon can be prevented. In particular, since the elastic coating waterproofing agent of the present invention has a water dispersibility, it is possible to prevent the risk of environmental damage and fire caused by solvent evaporation during construction, and excellent workability in wet conditions. Therefore, it can be usefully used as a waterproofing agent during civil works such as asphalt road construction or exterior construction of roofs or roofs of buildings.
