Abstract

The invention discloses a flame-retardant self-adhesive coiled material, which has a three-layer composite structure and is characterized in that the middle layer is a glass fiber felt and both the upper and lower surfaces of the glass fiber felt are polymer modified asphalt layers into which a flame retardant and an adhesion promoter are added. The invention provides a formula and a process for preparing the flame-retardant self-adhesive polymer modified asphalt water-proof coiled material. The flame-retardant self-adhesive polymer modified asphalt is prepared by mixing the flame retardant, the adhesion promoter, polymer, asphalt and the like. The invention further provides a method for preparing the coiled material.

Description

Technical field: [0001] The invention relates to a waterproof material for construction engineering, in particular to a formula of flame-retardant self-adhesive polymer modified asphalt. Background technique: [0002] In building fire safety, asphalt is an unavoidable place, because asphalt is a flammable material, and it is easy to catch fire due to traffic fires in the building, which further escalates the fire hazard. When asphalt burns, it first melts, drips, and flows, and then the molten beads burn, and then the burning beads drip and flow, causing the fire to spread and expand. During the combustion process, asphalt decomposes flammable gases such as hydrogen and methane, and the combustion of these flammable gases intensifies the fire. Therefore, the fire caused by the burning of asphalt materials has the characteristics of fierce attack, rapid expansion, and large smoke, which limits the use of modified asphalt-based waterproofing membranes in buildings with specia...
