Comparative example
Selecting materials: asphalt No. 70 is selected, an acrylic ester emulsion LFE01 (Shanghai Saifu chemical development Co., ltd.) is selected as a modifier, and a cationic emulsifier EM-310 (Shanghai Soifu materials Co., ltd.) is selected as an asphalt emulsifier.
160g of emulsifier is placed in a container, 3901g of water is heated to 80 ℃, the obtained hot water is added into the container filled with the emulsifier, the mixture is stirred until the emulsifier is completely dissolved in the water, 43g of modifier is added until the mixture is uniformly mixed, the modifier and the emulsifier undergo a crosslinking reaction, so that soap solution is obtained, the temperature of the soap solution is kept at 55-60 ℃, the measured pH value is=2.0, the pH value is adjusted to 2.0 by hydrochloric acid, and the soap solution is kept for standby.
572g of asphalt is heated to 130 ℃, and the temperature is kept at not lower than 120 ℃ and the asphalt is waited for use.
Turning on a colloid mill machine, pouring hot water at 100 ℃ to rotate, raising the whole temperature of the machine, discharging the hot water, adding prepared soap liquid into the machine, turning on the colloid mill machine again to rotate, adding the prepared asphalt into the machine after the colloid mill rotates stably at 5000r/min, adjusting the rotating speed to 6000r/min, and carrying out high-speed rotation fusion on the mixed asphalt and the soap liquid together by the colloid mill for 3-5 min to obtain the non-sticky wheel emulsified asphalt.
Experimental results: 50.20 percent of penetration; the softening point is: 45.3 ℃; the ductility is: 60cm.
The performances of the emulsified asphalt are lower than those of the non-stick emulsified asphalt prepared by the method.
From the results of the above examples and comparative examples, it can be seen that:
the softening point of the emulsified asphalt prepared by the method is higher than 40 ℃ of that of the conventional asphalt, so that the softening point of the asphalt can be improved on the premise of not changing other performances by the technical scheme provided by the invention. In addition, the technical scheme provided by the invention is feasible and highly applicable by adopting the emulsifying agent and the modifying agent with different proportions in the above embodiment.
The results in tables 1 and 2 show that the emulsified asphalt prepared by the invention has better softening point ductility than that of common asphalt. And the anti-skid value (experimental value is higher, 60-80) of the road surface test is better, so that the non-stick emulsified asphalt prepared by the invention has better adhesive property.
The practical application effect shows that the non-stick emulsified asphalt has excellent non-stick characteristic, and asphalt is not taken away under the condition of transportation and rolling of the mixture in the construction site.
The foregoing is merely a preferred embodiment of the present invention and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present invention, which are intended to be comprehended within the scope of the present invention.
