The test conditions were: the power of the nitrogen lamp is 6kW; the temperature (65+ -3) deg.C, the relative humidity (65+ -5)%, the water spraying period (wherein the nitrogen lamp is irradiated for 120min, and water is sprayed for 20 min) was 150min, the aging time was 720h, and the experimental results are shown in Table 3.

TABLE 3 Table 3

As can be seen from comparison of the data of comparative examples 1 to 3 in table 3 with the data of example 3, respectively, the basalt granule layer was replaced with an equal amount of limestone granule layer in comparative example 1, and when the pressure was 1.5MPa, the asphalt tile exhibited a water penetration phenomenon because the α, ω -di (acetoxy) oligoether ketone could not well encapsulate the limestone granule, so that the contact area between the limestone granule and the granite granule was larger than the contact area between the basalt granule and the granite granule, thereby making the gap between the limestone granule and the granite granule larger, and thus the water penetration phenomenon occurred.

In comparative example 2, the equivalent limestone granule layer was used instead of the granite granule layer, and when the pressure was 1.5MPa, the asphalt tile exhibited a water penetration phenomenon, because the α, ω -di (acetoxy) oligoether ketone could not well encapsulate the limestone granule, so that the contact area between the limestone granule and the basalt granule was not as small as that between the basalt granule and the granite granule, and the gap between the limestone granule and the basalt granule was large, thereby exhibiting a water penetration phenomenon.

The absence of pretreatment of basalt pellets and granite pellets in comparative example 3, the mass increase after soaking in water in comparative example 3 is much higher than in example 3, indicating that asphalt shingles can have better waterproof properties only by pretreatment of basalt pellets and granite pellets.

In example 3, the mineral particle layer is made of basalt particles and granite particles, the water impermeability of the asphalt tile can reach 2.0MPa, the asphalt tile can not generate water permeability even under the pressure of 2.0MPa, the mass increase after soaking is far smaller than that of comparative examples 1-3, and the pretreatment of the basalt particles and the granite particles by adopting alpha, omega-di (acetoxy) oligoether ketone is beneficial to improving the water resistance of the asphalt tile. The asphalt tile is characterized in that the contact area between the outer surface of the basalt particles wrapped in the spherical structure and the outer surface of the granite particles wrapped in the spherical structure is increased, so that gaps between the basalt particles and the granite particles are reduced, rainwater is not easy to enter from the gaps between the basalt particles and the granite particles in raining, asphalt tiles can be firmly attached to a roof, falling is not easy to occur, and water leakage of the roof is avoided.

According to the data of comparative examples 4-5 in Table 3, which are obtained by comparing with example 3, the amounts of the components in comparative examples 4-5 are not within the scope of the present application, the mass increase after soaking in water in comparative examples 4-5 is higher than that in example 3, and the falling amount is also higher than that in example 3, which means that the amounts of basalt granules and granite granules are not within the scope of the present application, and the waterproof performance of asphalt shingles is affected, therefore, the amounts of the components are only within the scope of the present application, so that asphalt shingles have better waterproof performance.

The above embodiments are not intended to limit the scope of the present application, so: all equivalent changes in structure, shape and principle of the application should be covered in the scope of protection of the application.
