[0023] Preparation of Flame Retardant Modified Asphalt Colored Asphalt Tile

[0024] 1. Preparation of flame retardant modified asphalt mixture for flame retardant modified asphalt layer

[0025] According to the parts by weight, first add 40~45 parts of heavy traffic asphalt into the reactor, heat up to 150°C for dehydration under stirring, and add 8~15 parts of naphthenic oil and styrene according to parts by weight when the temperature is raised to 200±5°C -4~8 parts of butadiene-styrene, and stirred at 200±5°C for 90 minutes to dissolve styrene-butadiene-styrene evenly, then add 30~35 parts of talcum powder, and stir for 60 minutes, Finally, lower the temperature to 130°C~150°C, add 4~8 parts of composite flame retardant, and stir for 30 minutes to make a flame-retardant modified asphalt mixture; set aside.

[0026] The heavy-duty asphalt in the flame-retardant modified asphalt layer of the present invention is No. 90 heavy-duty asphalt, and the composite flame retardant ...

Embodiment 1

[0030] Embodiment 1 (every part by weight is 100 kilograms, all the other embodiments are the same)

[0031] Add 4,000 kilograms of No. 90 heavy-duty asphalt into the reactor, heat up to 150°C for dehydration under stirring, and add 800 kilograms of naphthenic oil and 600 kilograms of styrene-butadiene-styrene in parts by weight at 195°C. And stir at 195°C for 90 minutes to dissolve styrene-butadiene-styrene evenly, then add 3000 kg of talcum powder, stir for 60 minutes, finally cool down to 130°C, add 400 kg of composite flame retardant, and stir for 30 minutes Minutes to prepare flame retardant modified asphalt mixture for use.

Embodiment 2

[0033] Add 4,200 kilograms of No. 90 heavy-duty asphalt in the reaction kettle, heat up and dehydrate under the stirring state, add 1,100 kilograms of naphthenic oil and 650 kilograms of styrene-butadiene-styrene according to parts by weight at 200 ° C, and Stir at ℃ for 90 minutes to dissolve styrene-butadiene-styrene evenly, then add 3200 kg of talc powder, stir for 60 minutes, finally cool down to 140°C, add 550 kg of composite flame retardant, and stir for 30 minutes to prepare into a flame retardant modified asphalt mixture for later use.

Abstract

A flame-retardant modified asphalt colored asphalt tile, the colored asphalt tile is a layered structure, from top to bottom are: colored mineral granular material layer, upper flame-retardant modified asphalt layer, glass fiber base , the lower flame-retardant modified asphalt layer, fine sand layer, adhesive layer and isolation layer, the seven-layer structure is consolidated into one, and the main raw materials of the flame-retardant modified asphalt layer are calculated in parts by weight: heavy traffic asphalt 40~50 8-15 parts of naphthenic oil, 4-8 parts of styrene-butadiene-styrene, 4-8 parts of composite flame retardant, 30-35 parts of talcum powder. The invention has good waterproof and decorative functions, and also has the advantages of good overall flame retardancy and low combustion smoke. The special composite flame retardant of the present invention produces non-combustible gas, partially decomposes and absorbs a large amount of heat when combustion occurs, and can reduce the amount of combustion smoke, and the synergistic flame retardant effect is obvious. The roof of the invention has the advantages of light load-bearing, safety and reliability, no hot fire heating during construction, simple construction, low comprehensive cost, energy saving and environmental protection.

Description

technical field [0001] The invention relates to a waterproof and flame-retardant composite material for building roof engineering. Background technique [0002] Linoleum tiles are imported from European and American countries, and have the characteristics of waterproof, decorative functions, rich colors, and easy construction. It is produced and used in large quantities in the United States and Canada, and is mainly used for sloping roofs of residential and commercial buildings. At the end of the 20th century, Shanghai and other coastal cities promoted the "slope conversion" and colored asphalt tiles became the preferred roofing materials. This not only changes the urban landscape, but also improves the drainage and heat insulation performance of the roof. The current promotion prospect of asphalt tiles is good. [0003] Asphalt-based building materials, shingles are flammable and can easily ignite when not properly protected or exposed to external flames. After the mater...
