Grease dirt cleaning agent for bituminous pavement and preparation method

Abstract

The invention relates to a grease dirt cleaning agent for bituminous pavement and a preparation method, and the grease dirt cleaning agent is prepared by the following steps: stirring and emulsifying sodium dodecylsulphonate (SDS) and alpha-olefin sulfonate (AOS) to prepare non-ionic surfactant mixed latex; stirring and emulsifying alkyl polyglucoside (APGS) and fatty alcohol-polyoxyethlene ether (FAPE) to prepare anionic surfactant mixed latex; mixing the non-ionic surfactant mixed latex with the anionic surfactant mixed latex; and adding ethanol and deionized water, stirring and emulsifying, and cooling to obtain the product. The grease dirt cleaning agent for bituminous pavement in the invention has the advantages of strong dirt-removing power, low production cost and convenient usage, and is easy to dissolve in water; all components thereof can be completely in biodegradation; and the used waste water can be discharged directly without toxicity and pollution on environment.

Description

technical field [0001] The invention relates to an asphalt pavement oil stain cleaner and a preparation method thereof, in particular to an asphalt pavement oil stain cleaner rich in various degradable surfactants and a preparation method thereof. Background technique [0002] With the rapid development of domestic high-grade highways, the proportion of road transportation in the national economy is increasing, and there are more and more trucks driving on roads. Due to the late start of my country's automobile machinery manufacturing level and the untimely maintenance of trucks, the condition of domestic trucks is generally not very good, and oil spills occur from time to time. This situation is especially common for trunk roads and expressway toll stations. In addition, during the construction of expressways, construction machinery and transport vehicles will often cause diesel pollution on the road surface. [0003] Asphalt pavement is a pavement form commonly used in hi...

Problems solved by technology

The penetration and swelling of asphalt by oil stains on the road surface directly affects the adhesion between asphalt and aggregates, causing the road surface to loosen, leading to pits and other diseases at the oil stains on the road surface; the swelling effect of oil stains on asphalt will also affect the composition of asphalt on the surface of the road surface, performance As the oil content in asphalt increases, the softening point decreases and the penetration increases, resulting in a decrease in the high temperature stability of the pavement surface and prone to rutting and other diseases

In addition, due to the increase of asphalt components and the decrease of viscosity, under the influence of gravity in the case of large void ratio, asphalt components will migrate to the lower layer of the mixture and cause segregation, resulting in the impact of asphalt binder on the road surface on the aggregate. If the pavement has a small porosity and the asphalt is not easy to infiltrate, the phenomenon of "oil flooding" on the surface may occur, which will greatly reduce the friction coefficient of the road surface and seriously affect driving safety.

[0004] After oil pollution occurs on the asphalt pavement, how to deal with it to eliminate the adverse effects of oil pollution on the asphalt pavement has been a technical problem that has plagued the road engineering industry. Some people try to use emulsified asphalt to spray the polluted road surface, but it has almost no effect. Now the only solution It is to excavate and replace the diesel polluted place, which is not only expensive and difficult to control the quality, but also affects the use of road surfaces and has a greater social impact
