Embodiment 1

[0029] Weigh by weight: 60 parts of heavy traffic road petroleum asphalt AH-70; 8 parts of decabromodiphenyl ether; 20 parts of magnesium hydroxide; 20 parts of aluminum hydroxide; 0.6 parts of coupling agent; 1.5 parts of blending agent; modifier 0.5 servings.

[0030] First, the heavy traffic road petroleum asphalt AH-70 is melted at a constant temperature of 80 °C, and decabromodiphenyl ether, magnesium hydroxide, aluminum hydroxide, coupling agent and blending agent are added to the molten asphalt, and they are added while stirring, so that Each component can be evenly mixed in the asphalt, then add the modifier, while adding the modifier, use a high-speed shearing machine at 1000r / min for 10min to make the modifier melt and swell, and then continue at 5000~ High-speed shearing at 6000r / min for 30min, the modifier gradually becomes thinner under the action of shearing, and finally the fine particles are evenly distributed in the asphalt, thus making the flame retardant asp...

Embodiment 2

[0032] Weigh by weight: 80 parts of heavy traffic road petroleum asphalt AH-70; 3 parts of decabromodiphenyl ether; 5 parts of magnesium hydroxide; 10 parts of aluminum hydroxide; 0.45 parts of coupling agent; 2 parts of blending agent; modifier 1.5 servings. The preparation process is the same as in Example 1.

Embodiment 3

[0034] Weigh by weight: 65 parts of heavy traffic road petroleum asphalt AH-70; 6 parts of decabromodiphenyl ether; 10 parts of magnesium hydroxide; 5 parts of aluminum hydroxide; 0.3 part of coupling agent; 1 part of blending agent; modifier 0.8 servings. The preparation is the same as in Example 1.

Abstract

The invention discloses road using inflaming retarding asphalt whose components part by weight are as follows: heavy traffic road petroleum asphalt 60-80, pentabromophenyl ether 3-8, magnesium hydroxide 5-20, aluminum hydroxide 5-20, coupling agent 0.3-0.7, tempering agent 1-3, and modifier 0.5-1.5. While burning it has high oxygen index to form stable charring layer to arise self extinguishing, little lamp black to reduce environment pollution. Thus it has wide application prospect, good socioeconomic performance. The preparing method is simple, effective, economic, convenient, and widely used.

Description

【Technical field】 [0001] The present invention relates to a kind of asphalt, more specifically, the present invention relates to a kind of road flame retardant asphalt. 【Background technique】 [0002] Asphalt is the final product of petroleum refining, and is a cheap and abundant building material widely used in construction for waterproof, moisture-proof, anti-corrosion, rust-proof, anti-leakage, etc. Some of its properties are unmatched by synthetic rubber and synthetic resin. However, asphalt is easy to burn, produces a large amount of black smoke, melts and flows when heated, and has a great fire hazard, and its application is also limited to a certain extent. Therefore, the research on the flame retardancy of asphalt has great practical significance. [0003] With the improvement of road users' requirements for road driving quality, smooth, wear-resistant and low-noise asphalt concrete pavement may replace cement concrete pavement and gradually become the mainstream o...
