Embodiment Construction

[0025] According to the formula and parts by weight described in Table 1, the above-mentioned several materials are put into the reaction container, and after fully stirring and miscible, the environmentally friendly asphalt flame-retardant and smoke-suppressing modifier of the present invention is obtained.

[0026] Table 1: The chemical composition of a kind of environment-friendly asphalt flame retardant and smoke suppression modifier of the present invention

[0027]

[0028] The above-mentioned inventive materials were mixed into asphalt at a ratio of 4% by mass, and stirred at a temperature of 180°C for 40 minutes to form a flame-retardant modified asphalt. The performance comparison with ordinary modified asphalt is shown in Table 2.

Abstract

The invention relates to an environmental-protection asphalt antiflaming smoke suppression modifier, which is characterized in that the modifier consists of the following components in part by weight: 18-22 parts of smoke suppression agent, 6-10 parts of coupling agent, 3-5 parts of bulking agent, 32-38 parts of nitrogen flame retardant and 31-35 parts of metal oxide. The antiflaming smoke suppression modifier disclosed by the invention has the characteristics of good dispersibility, easy addition, safety, environment protection and the like. After the modifier is added to asphalt mixture, the flame retardancy of a tunnel asphalt road surface is obviously improved, and smog generated by fire is reduced.

Description

【Technical field】 [0001] The invention relates to an asphalt flame-retardant and smoke-suppressing modifier, in particular to a special functional modification additive for environment-friendly asphalt. 【Background technique】 [0002] Asphalt is the final product of petroleum refining, and it is a cheap and abundant building material widely used in construction, used for waterproofing, moisture-proofing, rust-proofing and anti-seepage, etc. Asphalt is composed of four components: asphaltenes, colloids, aromatic hydrocarbons and saturated hydrocarbons. It is a mixture that can burn at high temperatures and produce a lot of smoke. Therefore, once a fire breaks out in the tunnel, the consequences will be disastrous. Therefore, when the asphalt pavement is used in the tunnel, it must be required that the asphalt pavement itself does not burn or delays burning, and at the same time, the harmful gas generated by heating is less. It can be seen that the development of flame-retard...
