Abstract

The invention relates to a self-adhesion waterproof coiled material cementing material and a waterproof coiled material prepared from the same, and belongs to the technical field of building waterproof engineering, the self-adhesion waterproof coiled material cementing material comprises the following raw materials: type I waterproof coiled material asphalt, ethylene tar, SBS, organic modified nano palygorskite, ammonium polyphosphate, naphthenic oil and modified chitosan; the modified chitosan is prepared by the following steps: dissolving chitosan in a methanol/acetic acid mixed solution with a volume ratio of 10: 1, heating to 50 DEG C, preserving heat, adding a flame retardant, heating to reflux, and reacting to obtain the modified chitosan. In the technical scheme, the palygorskite is a natural mineral microfiber, and after the palygorskite is added into the asphalt, the movement of asphalt molecules is limited, so that the viscosity of the asphalt is further increased, and the stiffness modulus of the asphalt is improved; in addition, a reinforced network composed of a large number of microfibers can improve the integrity of the asphalt, reduce the generation of microcracks on the surface of the asphalt, and contribute to improving the cohesive work of the asphalt and resisting the erosion of water.

Description

technical field [0001] The invention belongs to the technical field of construction waterproofing engineering, and particularly relates to a self-adhesive waterproofing membrane binding material and a waterproofing membrane prepared therefrom. Background technique [0002] With the development of the economy and the progress of the times, the requirements for building materials are getting higher and higher, and the original building materials can no longer meet the needs of the development of the times. Many buildings have reduced their service life due to water erosion, and people are paying more and more attention to the quality of waterproof materials. At present, elastomer (SBS) modified asphalt waterproofing membrane is still the mainstream product, especially when the roof is exposed, it is difficult to be replaced by other materials due to its excellent high temperature resistance. The coil needs to be hot-melted during construction. When the blowtorch is baked, the...
