Description

Flame-retardant self-adhesive waterproof roll cementing material, preparation method thereof and waterproof roll prepared from same
Technical Field
The invention belongs to the technical field of building waterproof engineering, and particularly relates to a flame-retardant self-adhesive waterproof roll cementing material, a preparation method thereof and a waterproof roll prepared from the same.
Background
With the development of economy and the progress of times, the requirements on building materials are higher and higher, and the original building materials cannot meet the development requirements of the times. Many buildings have a reduced life span due to water erosion. Along with the higher and higher requirements of people on the service life of buildings, the more and more attention is paid to the quality of waterproof materials. At present, the elastomer (SBS) modified asphalt waterproof coiled material is still a mainstream product, particularly when a roof is exposed for use, other materials are difficult to replace due to excellent high-temperature resistance, however, the elastomer (SBS) modified asphalt waterproof coiled material needs to be subjected to hot melting construction during construction, when a blast burner is baked, open fire has great fire hazard, and combustion of a surface PE film and partial modified asphalt cementing materials in the baking process can generate dioxin, hydrocarbon substances and the like due to heating decomposition, so that the environment is seriously polluted.
In view of the above, researchers have developed a number of self-adhesive waterproofing sheets with various properties. The self-adhesive coiled material is a novel waterproof material which can be constructed at normal temperature and does not need hot melting construction, is favored by the market at present, and has the growth rate far exceeding that of an elastomer (SBS) modified asphalt waterproof coiled material. CN200610127174.X and CN200610200760.2 are both self-adhesive waterproof rolls, but the rolls mainly include waterproof base material and self-adhesive layer, which is equivalent to adding self-adhesive layer on the basis of traditional rolls. Although the composite self-adhesive waterproof coiled material solves the problem of difficult construction, the compatibility between layers and the creep property of the waterproof coiled material are still important factors for limiting the performance of the waterproof coiled material. In contrast, it seems to be more advantageous to apply the self-adhesive waterproofing material directly onto the substrate to make a waterproofing roll. However, when the self-adhesive waterproof coiled material is exposed for a long time for use, mineral particles on the surface are easy to fall off and age, so that a large number of cracks or fissures are generated on the surface of the waterproof layer, and the waterproof function and the service life of the material are influenced.

As can be seen from the data in table 1: the peel strength was not satisfactory when the amount of styrene tar added was too small, and the heat resistance was not satisfactory when the amount of styrene tar added was too large. As can be seen from the data in the table, the self-adhesive coiled material prepared by the invention has the advantages of good waterproof performance, high tensile strength, good extensibility, excellent low-temperature flexibility and heat resistance. And the oxygen index is 29 after the chlorinated paraffin is added, which shows that the coiled material has good flame retardant property. As can be seen from the artificial climate accelerated aging experiment, the self-adhesive waterproof roll prepared by the formula has good aging resistance. The waterproof and impermeable coating can be suitable for industrial and civil building roofs, walls, kitchens and bathrooms, basements, swimming pools, roads and bridges, subways, reservoirs and other projects, is also suitable for the anticorrosion protection of metal containers and pipelines, is particularly suitable for the waterproof construction of projects which are not suitable for using open fire, and is also suitable for the construction of wet base surfaces.
