Abstract

The invention discloses a method for preparing an asphalt coating of a thermal insulation waterproof pad for the roof by flame retardant modification of organic montmorillonite-aluminum hydroxide. Themethod comprises the following steps: evenly mixing and stirring a waste tire rubber powder and a plasticizer, after placing and swelling, putting in a microwave oven to irradiate, evenly spreading on a low-temperature plasma screen, horizontally placing in a cavity of low-temperature plasma, turning on a power supply and a vacuum pump, discharging to produce low-temperature plasma glow, and obtaining an activated modified waste tire rubber powder; heating matrix asphalt, adding the activated modified waste tire rubber powder and evenly stirring, after heating and shearing at a high speed, adding an elastomer modifier, after evenly stirring and shearing, simply stirring with a stirring mechanism to obtain an elastomer-rubber composite modified asphalt; placing the elastomer-rubber composite modified asphalt in an oven, slowly adding organic montmorillonite and aluminum hydroxide, after stirring at a high speed, turning on a shear emulsion stirrer to shear, and discharging bubbles, andobtaining the organic montmorillonite-aluminium hydroxide flame retardant modified asphalt coating.

Description

technical field [0001] The invention belongs to the field of asphalt coating for heat-insulating and waterproof cushions on roofs, and in particular relates to a method for preparing asphalt coatings for heat-insulating and waterproof cushions on roofs by using organic montmorillonite-aluminum hydroxide flame-retardant modification. Background technique [0002] The rapid development of the automobile industry has brought about a sharp increase in the amount of scrapped tires. How to solve the problem of waste tires? [0003] The black pollution that comes, and the recycling and reuse of resources are of great significance to the development of circular economy and ecological chemical industry. [0004] Significance. Waste tires are a huge renewable resource, and the resource treatment of it by countries all over the world is also very important. [0005] more and more attention. [0006] Waste tires are high polymers, which are very difficult to degrade and cause great p...
