Embodiment 1

[0042] The preparation method of decabromodiphenylethane-organic montmorillonite is: prepare montmorillonite and decabromodiphenylethane with a mass ratio of 1:1; add montmorillonite (1000 mesh) to deionized water, Stir down for 30min, add NaCl crystals that account for 5% of the total mass of montmorillonite to form a mixed solution and continue to stir, control the temperature of the above mixed solution to rise to 70°C, adjust the Ph value of the above mixed solution to 7; Pour alkanes (with a particle size of 4 μm) as an intercalation agent into the mixed solution with a Ph value of 7 and continue to stir, control the rotation speed to 300r / min, control the temperature to rise to 80°C, stir for 1.5 hours and then let it stand for 30 minutes to obtain a flocculent precipitate. The product obtained by drying the above-mentioned flocculent precipitate in a drier at a temperature of 90° C. for 4 hours is the above-mentioned decabromodiphenylethane-organic montmorillonite.

Embodiment 2

[0044] The preparation method of decabromodiphenylethane-organic montmorillonite is: prepare montmorillonite and decabromodiphenylethane with a mass ratio of 1:2; add montmorillonite (2000 mesh) to deionized water, and Stir down for 30min, add NaCl crystals that account for 5% of the total mass of montmorillonite to form a mixed solution and continue to stir, control the temperature of the above mixed solution to rise to 70°C, adjust the Ph value of the above mixed solution to 7; Pour alkanes (with a particle size of 3 μm) as an intercalation agent into the mixed solution with a Ph value of 7 and continue to stir, control the rotation speed to 300r / min, control the temperature to rise to 85°C, stir for 1.5 hours and then let it stand for 30 minutes to obtain a flocculent precipitate. The product obtained by drying the above-mentioned flocculent precipitate in a drier at a temperature of 90° C. for 4 hours is the above-mentioned decabromodiphenylethane-organic montmorillonite. ...

Embodiment 3

[0046] The preparation method of decabromodiphenylethane-organic montmorillonite is: prepare montmorillonite and decabromodiphenylethane with a mass ratio of 1:3; add montmorillonite (3000 mesh) to deionized water, and Stir down for 30min, add NaCl crystals that account for 5% of the total mass of montmorillonite to form a mixed solution and continue to stir, control the temperature of the above mixed solution to rise to 70°C, adjust the Ph value of the above mixed solution to 7; Pour alkanes (with a particle size of 5 μm) as an intercalation agent into the mixed solution with a Ph value of 7 and continue to stir, control the rotation speed to 300r / min, control the temperature to rise to 85°C, stir for 2 hours and then let it stand for 30 minutes to obtain a flocculent precipitate. The product obtained by drying the above-mentioned flocculent precipitate in a drier at a temperature of 90° C. for 4 hours is the above-mentioned decabromodiphenylethane-organic montmorillonite.

Abstract

The invention discloses flame-retardant modified asphalt, a flame-retardant self-adhesive asphalt tile and a method for preparing the same, and relates to the technical field of building materials. The flame-retardant modified asphalt comprises, by weight, 25%-35% of NO.90 asphalt, 15%-25% of NO.200 asphalt, 7%-10% of butadiene styrene rubber, 2%-5% of styrene-butadiene-styrene block copolymers, 2%-3% of tackifying resin, 10%-15% of flame retardants, 10%-13% of rubber powder and 10%-15% of fillers. The flame retardants are decabromodiphenyl ethane-organic montmorillonite obtained from decabromodiphenyl ethane modified montmorillonite. The flame-retardant modified asphalt, the flame-retardant self-adhesive asphalt tile and the method have the advantages that the flame-retardant modified asphalt is excellent in flame retardance and adhesion and can be used for preparing the flame-retardant self-adhesive asphalt tile, and accordingly the flame retardance and the adhesion property of the flame-retardant self-adhesive asphalt tile can be improved.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a flame-retardant modified asphalt, a flame-retardant self-adhesive asphalt tile and a preparation method thereof. Background technique [0002] With the development of modern buildings, the roofs of most buildings are sloped roofs, and the main waterproof material for sloped roofs is asphalt shingles. Asphalt tile is a tile-shaped roof waterproof sheet made of glass fiber felt, dip-coated with modified asphalt waterproof layer, one side covered with colored mineral granules, and the other side covered with insulating material. It has good waterproof, decorative Features, easy construction and so on. In recent years, due to changes in architectural design and the use of new building components, higher and higher requirements have been placed on roof waterproofing materials. The state requires that the fire rating of building materials including high-rise buildings be adjusted ...
