Description
Technical Field
The invention belongs to the technical field of road engineering materials, and particularly relates to low-volatility odor asphalt and a preparation method thereof.
Background
Road asphalt is required to be mixed and paved at high temperature, and the mixing temperature is usually not lower than 150 ℃ and the paving temperature is not lower than 130 ℃. At the high temperature, the common road asphalt inevitably releases asphalt smoke, and the asphalt smoke contains polycyclic aromatic hydrocarbon, nitrogen, sulfur and other heterocyclic compounds and other harmful gases, which cause harm to the surrounding environment and the bodies of people. The asphalt sources are different, the chemical components are different to a certain extent, but most asphalt contains sulfur, which is the third largest element next to carbon and hydrogen in asphalt, and the sulfur content of some petroleum asphalt can be up to 9%. Road asphalt can cause great environmental pollution during production or construction if the sulfur elements are discharged into the environment as hydrogen sulfide or sulfur oxide. The novel ecological environment-friendly asphalt without or with slight taste is prepared, and the ecological environment-friendly asphalt mass production process is designed to solve the problem of volatile odor in the asphalt production and construction process.
The asphalt waste gas active inhibition technology comprises 4 methods of a spice covering method, a source improvement method, a cooling construction method and a deodorizing method. In addition to the fragrance masking method, the other 3 have respective distinct advantages, with a greatly developed mean. The deodorizing method is to add the additive into asphalt to react with volatile matters in asphalt to produce new non-exhausted matters and reduce harmful gas exhaust. The deodorizing method has good application effect and simple operation, and is the main development direction of the prior asphalt waste gas inhibition technology.

Further, the dispersion stabilizer is a polycarboxylic acid type dispersant.
A method of preparing any one of the low volatile odor asphalt described above, comprising the steps of:
s1, weighing granular alcohol, liquid alcohol and a dispersion stabilizer, and stirring for 15-30min at normal temperature to form a mixed preparation for later use;

Compared with the prior art, the invention has the beneficial effects that:
(1) The granular alcohol is dispersed in the asphalt to play a role in reducing viscosity and stabilizing, and particularly in the modified asphalt, the volatilization of sulfur-containing compounds caused by the cohesive polymerization of the modifier in the modified asphalt can be effectively inhibited; the liquid alcohol can also effectively adsorb part of volatile organic compounds and reduce the concentration of the volatile organic compounds.
(2) In addition, the granular alcohol and the liquid alcohol both contain organic alcohol, and alcohol organic matters can react with sulfur-containing flue gas in the asphalt, so that volatilization of organic matters in the asphalt is reduced, and flue gas and odor are reduced. The two inhibitors can effectively inhibit the generation of asphalt organic matters, react with the organic matters and adsorb volatile organic matters, and reduce the concentration of the volatile organic matters
(3) The addition of the dispersion stabilizer can effectively and equally disperse the granular alcohol and the liquid alcohol into the asphalt, and meanwhile, compared with other dispersants, the polycarboxylic acid dispersant can effectively prevent the adhesion of the modifier in the modified asphalt, reduce the viscosity, improve the stability and reduce the volatilization of asphalt smoke.

From the performance index detection data of the modified asphalt in table 1, the softening point and penetration of the low-volatility smell asphalt slightly increase with the increase of the composite inhibitor and the surfactant, and the ductility change is small, but the performance indexes basically have no large influence on the whole.
From the comparison data of the non-methane total hydrocarbon (NMHC) indexes of the low-volatility odor asphalt sample and the comparison sample in table 2, the average value of the non-methane total hydrocarbon of the volatile smoke of the low-volatility odor asphalt sample is reduced by about 80% compared with that of the sample asphalt, and the volatilization of organic matters in the asphalt is effectively reduced. In addition, as can be seen from the comparative example, the combination of the higher alcohol and the liquid alcohol can better reduce the volatilization of the asphalt smoke compared with the single alcohol; and the overall result is also affected by different dispersion stabilizers, and the addition of the polycarboxylic acid dispersion stabilizer can better improve the synergistic effect of two alcohols.
