Description

Roofing height prolongs multicore self-healing reflection self-adhesion coiled material

Technical Field

The utility model relates to a coiled material technical field especially relates to a roofing height prolongs multicore self-healing reflection self-adhesion coiled material.

Background

The roof waterproof engineering is a systematic engineering, it involves designing, waterproof material, waterproof construction and so on all aspects factors, waterproof material quality is especially important in waterproof engineering construction, the waterproof roll material that is using in the market at present is SBS modified asphalt roll material and self-adhesive polymer modified asphalt roll material and macromolecule roll material generally.

The coil with mineral particles on the upper surface of the SBS modified asphalt coil can be exposed for application, but the coil has large unit mass, and the material absorbs heat after sunlight irradiation in the daytime to cause the material to be subjected to high-temperature aging for a long time, so that the elongation of the coil is 40-50% at the maximum, the deformation resistance is weak, and the point elongation of the coil is zero after the coil is fully adhered to a base layer. The waterproof function can be lost after the deformation uneven settlement of the foundation is damaged by stretching; the self-adhesive polymer has low softening point, so the self-adhesive polymer has poor high temperature resistance and is not suitable for being exposed; the common polyethylene high polymer material has poor weather resistance and is not suitable for long-term exposure use,

for application, the polymer material construction application needs to coat a cement paste paving coiled material: firstly, preparing cement slurry, scraping the cement slurry to the thickness of about 1mm by using a scraper, and then paving a coiled material. Because the carelessness of constructors can cause the uneven thickness of the glue coating, the coiled material is not firmly paved and is not firmly adhered, and hollowing and wrinkling occur. The two layers of coiled materials and the lap edges are bonded by cement paste, the cement paste is easy to crack after being covered and pressed by external force, a water channeling channel is formed between the two layers, and the hidden danger of leakage is buried in the polymer in the application process; the SBS coiled material can not be completely in a molten fluid state due to uneven hot melting in the hot melting construction, and the phenomenon that the SBS coiled material cannot be completely attached to a base surface when the SBS coiled material is laid can cause that the coiled material is damaged and a leakage channel can be formed.

Therefore, designing a roofing high-delay multi-core self-healing reflection self-adhesion coiled material becomes a technical problem to be solved urgently by technical personnel in the field.
