Abstract

The invention discloses a flue gas inhibitor for asphalt road construction and belongs to the field of environment protection pavement application. The invention is characterized in that the flue gas inhibitor comprises a styrene-butadiene-styrene segmented copolymer (namely SBS), polyethylene (namely PE, ammonium phosphomolybdate and active carbon, wherein the weight of the SBS is 0.5-2.5% of that of asphalt; the weight of PE is 1-4% of that of asphalt; the weight of ammonium phosphomolybdate is 0.1-1% of that of asphalt; and the weight of active carbon is 0.5-2.5% of that of asphalt. According to the invention, the problem that there are a large amount of flue gas during asphalt road construction and the flue gas is severely harmful to the health of employees as well as the environment in the prior art is solved. The inhibitor provided by the invention can be used to reduce flue gas generated during asphalt road construction, and decrement rate of flue gas at the best ratio of the inhibitor is 33.59%. Due to the addition of the inhibitor, the harm of flue gas generated during asphalt road construction to the environment as well as employees is weakened. In addition, investment of the inhibitor is low. Thus, the flue gas inhibitor is worth of popularization.

Description

Flue gas inhibitor in a kind of asphalt roads construction

Technical field

The invention belongs to environment protection pavement Application Areas, relate in particular to the flue gas inhibitor in a kind of asphalt roads construction.

Background technology

Recent years, China's road traffic had development faster, present stage be no matter newly-built or the road engineering of reconstruction and enlarging in the general bituminous pavement that adopts, for motorway and high-grade highway, what adopt bituminous concrete pavement exceedes 90%, in recent years bituminous pavement because of its intensity high, traffic is open fast, drive comfortable, traffic safety, simple maintenance, long service life, reproducible utilization, be conducive to the advantages such as environment protection and widespread use, but no matter asphalt roads is mix in construction, transportation, discharging, Manual, when machinery paves still compacting, capital produces a large amount of flue gases, be called for short the people's such as IARC and Lunsford, Reinke, Hatjian and Shi Baocheng detection according to international cancer research health organization and find the polycyclic aromatic hydrocarbons material that contains carcinogenesis in the flue gas of road bitumen high temperature generation, this material can produce more serious harm to practitioner's healthy and environment, be engaged in pitch operating personnel pain attack rate all higher with trouble cancer probability, therefore particularly important to the flue gas inhibitor research in asphalt roads construction.

Summary of the invention

The object of this invention is to provide the flue gas inhibitor in the construction of a kind of asphalt roads, solved flue gas in the road construction of prior art medium pitch large and can produce the problem compared with serious harm to practitioner's healthy and environment.

In order to achieve the above object, the present invention by the following technical solutions.

A flue gas inhibitor in asphalt roads construction, comprises that styrene-butadiene-styrene block copolymer is that SBS, polyethylene are PE, ammonium phosphomolybdate, gac; Wherein the weight of SBS be pitch weight 0.5 ~ 2.5%, the weight of PE be pitch weight 1 ~ 4%, the weight of ammonium phosphomolybdate be pitch weight 0.1 ~ 1%, the weight of gac is 0.5 ~ 2.5% of pitch weight.

Flue gas inhibitor in a kind of asphalt roads construction, wherein the weight of SBS be pitch weight 1%, the weight of PE be pitch weight 2.5%, the weight of ammonium phosphomolybdate be pitch weight 0.5%, the weight of gac be pitch weight 1% time, Asphalt Production cigarette rate minimum, for 58.6754mg/100g, flue gas decrement is 33.59%, is optimal inhibition agent proportioning.

The invention has the beneficial effects as follows: solved flue gas in the road construction of prior art medium pitch large and can produce the problem compared with serious harm to practitioner's healthy and environment, the flue gas that inhibitor of the present invention can reduce in asphalt roads construction produces, and wherein flue gas decrement is 33.59% when optimal inhibition agent proportioning; Weaken the adding of inhibitor of the present invention the harm to environment and practitioner of flue gas in asphalt roads construction, dropped into lowly, be worthy to be popularized.

Embodiment

Embodiment 1, flue gas inhibitor in a kind of asphalt roads construction, selection add the weight of SBS be pitch weight 0.5%, the weight of PE be pitch weight 1%, the weight of ammonium phosphomolybdate be pitch weight 0.1%, the weight of gac is 0.5% of pitch weight, reaches the object that reduces the flue gas in asphalt roads construction.

Embodiment 2, flue gas inhibitor in a kind of asphalt roads construction, selection add the weight of SBS be pitch weight 1%, the weight of PE be pitch weight 2.5%, the weight of ammonium phosphomolybdate be pitch weight 0.5%, the weight of gac is 1% of pitch weight, reaches the object that reduces the flue gas in asphalt roads construction.

Embodiment 3, flue gas inhibitor in a kind of asphalt roads construction, selection add the weight of SBS be pitch weight 2.5%, the weight of PE be pitch weight 4%, the weight of ammonium phosphomolybdate be pitch weight 1%, the weight of gac is 2.5% of pitch weight, reaches the object that reduces the flue gas in asphalt roads construction.

The part that do not describe in detail of the present invention; the known technology that is those skilled in the art of the present technique, should be understood that, for those of ordinary skills; can be improved according to the above description or convert, and all these improvement and conversion all should belong to the protection domain of claims of the present invention.
