Background Art

[0002] A waterproof roll material is a flexible waterproof material having a specific width and thickness and can be wound in a roll shape, and is also the most currently used waterproof material.

In this waterproof roll material, the penetration reaction adhesive layer plays an adhesive role between layers, and the quality of its performance directly affects the tensile properties of the roll material.

[0027] Example 6 This differs from Example 1 in the following respects. S2:35 parts of 90# asphalt were heated to 185°C and uniformly mixed with 2 parts of carboxylated styrene-butadiene rubber, 10 parts of SBS 4452, 3.5 parts of petroleum resin C9, 5 parts of dibutyl phthalate, 0.6 parts of antioxidant 1010, 40 parts of talc, and 10 parts of 2-cyanoaniline.

The mixture was then rolled to sequentially obtain the first, second, and third penetration reaction adhesive layers, thereby obtaining a high-strength double-layered double polymer film base waterproof roll material.

[0028] Example 7 This differs from Example 1 in the following respects. S2:35 parts of 90# asphalt were heated to 185°C and uniformly mixed with 2 parts of carboxylated styrene-butadiene rubber, 10 parts of SBS 4452, 3.5 parts of petroleum resin C9, 5 parts of dibutyl phthalate, 0.6 parts of antioxidant 1010, 40 parts of talc, and 12 parts of 2-cyanoaniline.

[0029] Example 8 This differs from Example 1 in the following respects. S2:35 parts of 90# asphalt were heated to 185°C and uniformly mixed with 2 parts of carboxylated styrene-butadiene rubber, 10 parts of SBS 4452, 3.5 parts of petroleum resin C9, 5 parts of dibutyl phthalate, 0.6 parts of antioxidant 1010, 40 parts of talc, and 7 parts of 2,6-dicyanoaniline.

The mixture was then rolled to sequentially obtain the first, second, and third penetration reaction adhesive layers, thereby obtaining a high-strength double-layered double polymer film base waterproof roll material.

[0030] Comparative Example 1 This method differs from Example 1 in that 2-cyanoaniline is not added.

[0031] The tensile properties of the waterproof roll materials obtained in Examples 1-8 and Comparative Example 1 were measured using the method described in GB / T 35467-2017, "Waterproof Roll Materials for Installation in a Wet State." The measurement results are shown in Table 1.

[0032] Table 1: Tensile properties of waterproof roll material [Table 1]

[0033] As can be seen from Table 1, the waterproof roll material provided in the present invention has a maximum longitudinal tensile strength of 1192 N / 50 mm or more and a maximum transverse tensile strength of 1270 N / 50 mm or more, exhibiting excellent tensile properties.

[0034] Compared to Comparative Example 1, the addition of a cyanoaniline compound in Example 1, while the absence of a cyanoaniline compound in Comparative Example 1, resulted in higher maximum longitudinal and transverse tensile strengths for the waterproof roll material obtained in Example 1 compared to Comparative Example 1. This demonstrates that the tensile properties of the waterproof roll material can be improved by adding a cyanoaniline compound.

[0035] Compared to Examples 4-7, the mass ratio of the plasticizer to the cyanoaniline compound in Example 1 was 5:3, while in Example 4 it was 1:1, in Example 5 it was 5:7, in Example 6 it was 1:2, and in Example 7 it was 5:12. The maximum longitudinal and transverse tensile strengths of the waterproof roll materials obtained in Examples 4-6 were higher than those in Examples 1 and 7. This indicates that the tensile properties of the waterproof roll material can be further improved when the mass ratio of the plasticizer to the cyanoaniline compound is 1:1-2.

[0036] In this invention, the various properties of the waterproof roll material obtained in Example 1 were measured. The detection method used for reference is recorded in Table 2. The detection results are recorded in Table 3.
