As can be seen from the combination of example 2 and comparative example 1 and the combination of table 3, compared with comparative example 1, SIS was used in place of SBR in the waterproof roll manufactured in comparative example 1 in the waterproof roll manufactured in example 2, and the speed of oxidation of the lower base material layer or the upper base material layer after direct contact with the external environment was slowed down, thereby improving the stability of the tackiness of the waterproof roll, and as can be seen from the experimental results in table 3, the tackiness of the waterproof roll manufactured in example 2 was maintained for 187 days after peeling the anti-sticking film, and the tackiness of the waterproof roll manufactured in comparative example 1 was maintained for only 7 days after peeling the PE film, so the scheme proposed in this application achieves the effect of extending the storage period of the waterproof roll.
As can be seen from the combination of example 2 and example 4 and the combination of table 3, compared with example 2, the waterproof roll manufactured in example 4 uses 200 # asphalt instead of 90 # asphalt in example 2, the amount of three-wire oil is reduced, thereby further slowing down the oxidation speed of each raw material in the upper base material layer and the lower base material layer, improving the stability of the adhesiveness of the waterproof roll, as can be seen from the experimental results in table 3, the adhesiveness of the waterproof roll manufactured in example 2 is kept for 187 days after peeling the anti-adhesive film, and the adhesiveness of the waterproof roll manufactured in example 4 is kept for 252 days after peeling the PE film, thereby obtaining the effect of prolonging the storage period of the waterproof roll.
As can be seen from the combination of the PE films used in preparation example 2 and comparative example 1 and the table 4, the anti-sticking film prepared in preparation example 2 is made of blending PET and HDPE, and as can be seen from the experimental results in table 4, compared with the PE film, the anti-sticking film prepared in preparation example 2 has better tear resistance and impact resistance, and is less prone to breakage when being broken by external force, thereby reducing the damage degree of the anti-sticking film caused by external force, increasing the protection effect on the lower base material layer, and further prolonging the storage period of the waterproof coiled material.
As can be seen from the combination of examples 4 and 8 and the combination of tables 4 and 5, the anti-adhesive film prepared in preparation example 2 was used in example 4, the anti-adhesive film prepared in preparation example 5 was used in example 8, and mica powder and silicone oil were added to the anti-adhesive film prepared in preparation example 5, compared with the anti-adhesive film prepared in preparation example 2, it can be seen from table 5 that the average peeling force between the anti-adhesive film of example 8 and the lower base material layer was improved by 2 times compared with the average peeling force between the anti-adhesive film of example 4 and the lower base material layer, so that the connection strength between the anti-adhesive film and the lower base material layer was improved by spraying of mica powder, and at the same time, as can be seen from table 4, the anti-adhesive film prepared in preparation example 5 was also lower in resistivity than the anti-adhesive film prepared in preparation example 2, the anti-static property of the anti-adhesive film prepared in preparation example 5 was better, the problem that dust was easily absorbed on the surface of the anti-adhesive film was alleviated, the influence of dust on the lower base material layer was reduced, the stability of the adhesive roll was improved, and therefore the effect of prolonging the storage period of the waterproof roll was obtained.
As can be seen from the combination of examples 4, 8, 10 and 11 and the combination of tables 4 and 5, the anti-adhesive film prepared in example 2 was used in example 4, the anti-adhesive film prepared in example 5 was used in example 8, the anti-adhesive film prepared in example 7 was used in example 10, the anti-adhesive film prepared in example 8 was used in example 11, mica powder and silicone oil were added to the anti-adhesive film prepared in example 5, mica powder and silicone oil were not added to the anti-adhesive film prepared in example 5, and silicone oil was not added to the anti-adhesive film prepared in example 7, as can be seen from the test results of tables 4 and 5, the average peel force between the anti-adhesive film and the lower base material layer of the waterproof roll material prepared in example 8 was the largest, and the anti-adhesive film prepared in example 5 had the lowest resistivity, so that the synergy of the mica powder and silicone oil was reflected, and the anti-adhesive film prepared in example 5 was capable of improving the connection strength between the anti-adhesive film and the lower base material layer and also alleviating the problem of dust easily adsorbed on the surface of the anti-adhesive film.
It can be seen from the combination of example 8 and example 12 and the combination of table 5 that the difference between example 8 and example 12 is that example 8 is heated simultaneously during the secondary pressing process of preparing the waterproof roll, while example 12 is at normal temperature during the secondary pressing process of preparing the waterproof roll, and as can be seen from table 5, the average peeling force between the release film and the lower base material layer of the waterproof roll prepared in example 8 is 1.67 times that of example 12, thus, the effect of the process condition on improving the connection strength between the release film and the lower base material layer is reflected, thereby increasing the protective effect on the lower base material layer, and further prolonging the storage period of the waterproof roll.
