[시험 1] 아스팔트 방수제의 성능시험 [Test 1] Performance test of asphalt waterproofing agent
상기의 폴리우레탄 변성 아스팔트 방수 도포제와 기존 사용되는 아스팔트 방수제의 비교시험 결과 폴리우레탄 변성 아스팔트 방수 도포제가 부착성,내마모성 , 굴곡강도, 탄성, 내열성, 내노화성이 우수하였다. 구제적인 내용은 표 1과 같다. As a result of the comparison test between the polyurethane modified asphalt waterproof coating agent and the conventional asphalt waterproofing agent, the polyurethane modified asphalt waterproof coating agent was excellent in adhesion, abrasion resistance, flexural strength, elasticity, heat resistance, and aging resistance. Details are shown in Table 1.

[시험 2] 기존의 방수도포제와의 인장강도 및 신장률 비교 실험 [Test 2] Comparison of tensile strength and elongation rate with existing waterproof coating agent
본 발명의 인장성능을 비교예와 비교해서 실험을 한다. 도면 1의 a는 본 발명의 실시예에 의해서 제작된 도막의 시편이고, 도면 1의 b는 비교예인 종래의 에어 브라운(Air brown) 아스팔트 도포제 제품(이하 ABA 라고 한다)이다. 인장성능의 비교를 위해 인장 강도와 신장률을 측정한다. 본 발명과 ABA의 시편을 각각 3개씩 제작한다. 시편 형틀에서 시편을 4일간 양생하며, 시편 규격은 KS M 6518로 한다. The tensile performance of this invention is compared with a comparative example and an experiment is carried out. Figure 1a is a test piece of the coating film produced according to the embodiment of the present invention, Figure 1b is a conventional air brown asphalt coating product (hereinafter referred to as ABA) as a comparative example. Tensile strength and elongation are measured for comparison of tensile performance. Three specimens of the present invention and ABA are prepared. The specimens are cured for 4 days in the specimen form, and the specimen standard is KS M 6518.
각각의 시편을 표준 상태에서 1시간 이상 방치한 후 인장 시험기에 물림간격 이 60mm가 되도록 시편을 부착하고, 500mm/min의 인장속도로 시편이 파단될 때까지 인장한다. After each specimen has been left in the standard condition for at least one hour, the specimen is attached to a tensile tester with a bleeding interval of 60 mm and tensioned until the specimen breaks at a tensile speed of 500 mm / min.
[표2] 인장성능 시험결과 [Table 2] Tensile performance test results
표 2는 그 실험 결과이고, 도 2는 시편의 인장 성능 시험에서 절단된 시편의 사진이다. Table 2 is the experimental results, Figure 2 is a photograph of the specimen cut in the tensile performance test of the specimen.
본 발명은 위의 표와 같이 인장강도는 기존의 제품과 비교해서 2배 정도의 향상을 보였고, 신장률 또한 2.5배의 향상을 보였다. 도 2의 a는 본 발명의 절단사진으로 인장강도와 신장률이 높기 때문에 형체의 변성 없이 절단되었다. 그러나 ㄷ도 2 b의 ABA는 그 형태 유지를 못 하고 늘어나다가 다시 그 형태가 복원되지 못하고 늘어난 상태에서 절단되었다. In the present invention, as shown in the above table, the tensile strength was improved by about 2 times compared to the existing product, and the elongation was also improved by 2.5 times. Figure 2a is a cutting picture of the present invention because of high tensile strength and elongation was cut without deformation of the body. However, the ABA of c 2 b did not retain its shape and was increased, but was cut off in its extended state without being restored.
이 실험결과는 본 발명이 큰 인장강도로 인하여 내구성이 우수하며, 큰 신장률에 의해 시공된 후 하지면(콘크리트 바닥 등)의 신축팽창에 대한 적응성이 우수하다는 것을 보여준다.The experimental results show that the present invention has excellent durability due to the high tensile strength and excellent adaptability to expansion and contraction of the lower surface (concrete bottom, etc.) after being constructed by the large elongation.
