TABLE 3 comparison of the results of the experimental treatments of the examples and comparative examples
The coil materials in the above six comparative examples and examples were tested to compare the low-temperature flexibility, heat resistance and adhesive peel strength:
table 4 comparative example to comparative example physical property test
From the comparison results, when the addition amount of the composition is less than 10%, the prepared flame-retardant fireproof isolation sand cannot prevent the damage of open fire, the low-temperature flexibility and the bonding peel strength have small-amplitude descending trends along with the increase of the addition amount of the composition, and when the addition amount exceeds 20%, the low-temperature flexibility is unqualified, the bonding peel strength is at a critical value, the service performance of the product is influenced, so the addition amount does not exceed 20%.
In conclusion, the flame-retardant fireproof isolation sand for the asphalt-based pre-paved waterproof coiled material fundamentally solves the problems that an asphalt layer is not heat-resistant and fireproof, and can effectively prevent the asphalt layer of the waterproof coiled material from being damaged due to a fire source and a heat source in the later construction process after the coiled material is paved. The protective layer is thoroughly avoided, the construction convenience is improved, meanwhile, the waterproof layer is completely protected, and the hidden danger of water leakage and water channeling is prevented.
