Problems solved by technology

The existing disadvantages are: ① Diesel oil and water are mixed unevenly, diesel oil is concentrated during the brushing process, and the isolation effect is poor
②Diesel oil has a strong effect of dissolving asphalt, resulting in a decrease in asphalt cohesion, a decrease in road surface quality, and a short service life of the road surface. ③The price of diesel oil is relatively high and the dosage is large. The separation agent of diesel and water mixture is 2500-2600 yuan per ton. increase construction cost
But this patent application uses more chemicals, the preparation method is complicated, and the use cost is high

Effect test

Embodiment 1

[0012] Take 100 kg of soybean oil and 12 kg of ZR-1 vegetable oil emulsifier, and mix them at room temperature with a stirrer at a stirring speed of 30-50 rpm to make emulsified oil. When the emulsifier is not completely dissolved, it can be properly heated Carry out, the temperature is between 40~90 degrees. Sampling of the emulsified oil for storage stability test, regular inspection of the samples, it shows that the emulsified oil has no oil-water separation within 24 hours, and less than 1 / 10 of the emulsified oil has oil-water separation after more than 72 hours, and it is still mixed evenly into emulsification after stirring state.

Embodiment 2

[0014] Take 10 kg of prepared emulsified oil and 80 kg of tap water, and mix them evenly at room temperature with a stirrer at a stirring speed of 30-50 rpm to make No. 1 release agent, which is used to isolate rubber wheels and asphalt mixture. Take 10 kg of prepared emulsified oil and 100 kg of tap water, and mix them at room temperature with an agitator at a stirring speed of 30-50 rpm to make a No. 2 release agent, which is used to isolate vehicles transporting asphalt mixture. After use, it was shown that no asphalt mixture adhesion phenomenon was found on transport vehicles and rubber wheels.

Abstract

The invention relates to a separant for an asphalt pavement construction machine. The separant comprises vegetable oil, an emulsifier and water. The vegetable oil and the emulsifier are firstly prepared into emulsified oil, and then the emulsified oil and the water are prepared into the separant. The weight ratio of the vegetable oil to the emulsifier in the emulsified oil is 100: 10-16. The weight ratio of the emulsified oil to the water in the separant is 1: 6-16. The weight ratio of the emulsified oil to the water in the separant for a rubber wheel device is 1: 8-10, and the weight ratio of the emulsified oil to the water in the separant for a transportation vehicle is 1: 10-12. The separant disclosed by the invention has the beneficial effects that the separant mixed solution are stable in performance, is not dissolved in asphalt, good in the separation effect, simple in the preparation method is simple, and low in the construction cost.

Description

technical field [0001] The invention belongs to the technical field of chemical composition preparation, and relates to asphalt mixture construction auxiliary materials, in particular to a release agent for asphalt pavement construction machinery. technical background [0002] In the construction process of asphalt pavement, rolling is the last process. The quality of rolling effect directly affects the mechanical properties and functional characteristics of asphalt concrete pavement. High-quality rolling can make the asphalt pavement layer achieve a high degree of compaction. , and can make it have a good balance to ensure that the service life of the pavement meets or exceeds the design requirements. [0003] In order to prevent and reduce the asphalt mixture from sticking to transport vehicles and road roller machinery and equipment, a release agent is used in the construction process. The prior art uses a 1:3 mixture of diesel oil and water as a release agent for sprayi...
