In this case, the waterproof sheet is manufactured in the size and thickness to maintain the waterproof performance, so it is easy to carry and install.
In order to verify the effect of vegetable husk oil, the present invention produced a sheet according to the presence or absence of a covering oil and measured the adhesive strength with concrete specimens.
The mixing ratio of the examples in which 10% of the covering oil was added and the blending ratios of the comparative examples were as shown in Table 1 below, and the experiment was conducted in accordance with [KS F 4934].
Tests were conducted by attaching a sheet prepared by mixing ratios of the above Examples and Comparative Examples to a concrete specimen.
At this time, specimens of dry condition and 95% moisture content of concrete specimens were prepared and subjected to a peel-out test at 25 ° C and an adhesion strength test at 5 ° C to check whether the adhesiveness was maintained at low temperature Respectively.
Table 2 shows the results of the peel-out test at 25 ° C, and it can be confirmed that the adhesive strength of each of Examples is higher than that of Comparative Examples in a dry state and a wet state.
Therefore, the present invention minimizes environmental pollution by using a physical property outer film,

The sheet using the asphalt waterproofing composition according to the present invention can exhibit the waterproof performance by maintaining the adhesive force even under the environmental condition where the waterproof performance may be lowered.
In particular, when the sheet is produced from the adhesive property of the high-adhesive sealant, the releasability with the lower releasing paper or the release film may be deteriorated.
In particular, when the film is exposed to ultraviolet rays for a long period of time at a high temperature in summer, the temperature rises and it may not be peeled off from the releasing paper and the release film.
Table 4 shows the results of testing the releasability of the waterproof sheet at 30 to 60 ° C. The results were obtained by heating the waterproof sheet using a heater and confirming the releasing performance.
Further, the asphalt composition according to the present invention is eco-friendly by using vegetable sheath oil and using carbon black extracted from waste tires.
In addition, it is easy to work because it is constructed without special heating device at the time of construction, shortening the working time, and of course there is no risk of topic.
