Abstract

The invention discloses a smoke suppression low-odor modified asphalt coiled material coating material, a preparation method thereof and a modified asphalt coiled material. The coating material comprises matrix asphalt, a softening agent, a free radical scavenger, a metal organic framework compound, an inorganic adsorption material, a reaction type odor inhibitor, a high polymer modifier, tackifying resin, rubber powder and a filler. According to the invention, the free radical scavenger is added, so that a small molecule volatile gas generated by free radical reaction is reduced; the metal organic framework compound can be used for efficiently selectively adsorbing polycyclic aromatic hydrocarbon sulfur-containing thiophene substances and reducing the emission of the polycyclic aromatic hydrocarbon sulfur-containing thiophene substances; the inorganic adsorption material is used for reinforcing the interaction between volatile organic matters and the asphalt matrix, so that the overall emission is reduced; the reaction type odor inhibitor reacts with mercaptan in the asphalt, and the emission of the mercaptan as one of peculiar smell sources and hydrogen sulfide is reduced. The test result shows that smoke-inhibiting and odor-removing active ingredients are added, the flue gas volatilization amount of the modified asphalt coating material is reduced by more than 80% at 180 DEGC, and pollutant emission and peculiar smell source emission are remarkably reduced.

Description

technical field [0001] The invention belongs to the field of building waterproof materials, and more specifically relates to a smoke-suppressing and low-odor modified asphalt coil coating material, a preparation method thereof, and a modified asphalt coil. Background technique [0002] Asphalt has the advantages of cheap price, corrosion resistance, good water resistance, and certain adhesion, but it also has disadvantages such as poor temperature stability, low-temperature brittleness, and poor aging resistance. These shortcomings can be overcome by adding polymer modifiers and To make asphalt materials have new energy, generally the modification of asphalt materials with polymers needs to be carried out at a higher temperature to promote the swelling of polymers in asphalt and increase the swelling rate. [0003] Chinese patent application CN106398244A and Chinese patent CN104553130B respectively prepare self-adhesive asphalt waterproofing membrane, elastomer modified asph...
