Especially for areas with large daily temperature difference, the adhesion between the coiled material and exposed shale particles can be damaged by the ice and snow which are repeatedly frozen and thawed, so that the shale particles are quickly dropped off, the asphalt layer is exposed and exposed in the air, the exposure standard can not be met, and the waterproof service life and the waterproof effect are greatly reduced. Repeated freezing and thawing of ice and snow can also destroy the bonding of the building base layer and the waterproof roll to form a quick boiling channel, so that the building is directly challenged to waterproof.
The basic idea of building water prevention is 'prevention and drainage combination', ice and snow covered for a long time cannot be melted and then is discharged in time, and the basic idea is the root cause of damage to a waterproof product.
Therefore, in order to reduce the freezing point of the waterproof roll material and rain, snow and ice which are in direct contact with the waterproof roll material, accelerate the melting and discharging of the ice and the snow, ensure the service life of the exposed waterproof roll material product and reduce the hidden danger of quick boiling, a new modified asphalt waterproof roll material and a preparation method thereof are urgently needed.

Table 2 shows comparative data of the aged comprehensive properties of modified asphalt waterproof rolls (including the exposed anti-freezing self-melting snow-ice type modified asphalt waterproof rolls of examples 1 to 4 and commercially available ordinary SBS PY PE M4-10 (GB 18242-2008)) after 672h artificial climate accelerated aging. Table 3 shows comparative data for the results of the mold resistance test.
TABLE 1 comparison of the Pre-aging Performance data
| Numbering | Freezing point/. Degree.C | Mineral granule adhesion/g | Low temperature decay/. Degree.C | 100% Ice melting Rate temperature/. Degree C |
| Example 1 | -1.5 | 5.3 | 8.8 | -2.0 |
| Example 2 | -2.0 | 4.4 | 7.6 | -2.4 |
| Example 3 | -4 | 3.3 | 7.4 | -4.2 |
| Example 4 | -5.5 | 2.0 | 5.5 | -5.7 |
| Comparative example | 0 | 7.3 | 11.8 | 0.1 |
As can be seen from the data in table 1:
1) Because the upper surface is anti-freezing and self-melting ice and snow type modified asphalt layer and the snow melting agent is added into the pre-immersion oil, the freezing point and the ice melting temperature of the modified asphalt waterproof coiled materials of the embodiments 1 to 4 are obviously reduced compared with the comparative example, which shows that the ice and snow, etc. covered on the surface of the modified asphalt waterproof coiled material product are easier to melt and harder to freeze.
2) Due to the addition of the anti-stripping agent, the adhesion of the mineral aggregate of the upper surface isolation layer is obviously improved compared with that of a comparative example, so that the adhesion of the mineral aggregate of the upper surface isolation layer and the anti-freezing self-melting ice and snow type modified asphalt layer of the upper surface is stronger, and the modified asphalt waterproof coiled material is continuously protected from direct ultraviolet radiation.
3) Due to the addition of polyphosphoric acid (PPA), the aging low-temperature attenuation of the modified asphalt waterproof coiled materials of examples 1-4 is obviously reduced compared with that of the comparative examples, and the modified asphalt waterproof coiled materials are more difficult to crack and the like.

As can be seen from the data in table 2:
1) The modified asphalt waterproof rolls of examples 1-4 have small changes in the freezing point and 100% ice melting rate due to the addition of the anti-freezing self-melting ice-snow type modified asphalt layer on the upper surface and the addition of the snow melting agent in the pre-immersion oil, which indicates that the modified asphalt waterproof roll product of the invention can maintain long-term ice melting capability.
2) The modified asphalt waterproof coiled material is subjected to chemical reaction due to the addition of polyphosphoric acid (PPA), so that the adhesion and the low-temperature attenuation amplitude are obviously improved compared with those of a comparative example.
TABLE 3 comparison of results of the mold resistance test
As can be seen from the data in table 3:
compared with the modified asphalt waterproof coiled material product of the comparative example, the modified asphalt waterproof coiled material products of examples 1 to 4 added with the mildew-resistant agent have the advantages that the mildew-resistant grade is improved, the mildew-resistant effect is obviously improved, and the waterproof life of the modified asphalt waterproof coiled material product can be further ensured.
