Technical Field

The invention belongs to the technical field of building waterproof engineering, and particularly relates to a slow-release type anti-freezing flame-retardant self-adhesive waterproof coiled material.

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 in China is still a mainstream product, and particularly when the waterproof coiled material is used on the exposed roof, the excellent high-temperature resistance of the waterproof coiled material is difficult to replace by other materials. However, the elastomer (SBS) modified asphalt waterproof roll needs to be subjected to hot melting construction during construction, when a blowtorch is baked, open fire has a great fire hazard, and combustion of the surface PE film and partial modified asphalt cement in the baking process also generate some dioxin, hydrocarbon substances and the like due to heating decomposition, thereby causing serious pollution to the environment.

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 temperature is lower than 0 ℃, the air is humidified, and the frost is easily formed to form thin ice. Under the weather conditions of freezing rain, frosting, snow accumulation, icing and the like, a large number of cracks or cracks are generated on the surface of the waterproof layer, and the waterproof function and the service life of the coiled material are influenced.
