Problems solved by technology

However, the chemical depressant used in this invention to achieve its effect is all purchased from other manufacturers, which virtually increases the production cost.
[0006] In addition, most of the materials used in the existing snow melting technology are non-renewable resources. With the rapid development of society and economy, the resources are gradually exhausted, especially the increasing consumption of non-renewable resources, which makes human beings gradually fall into the dilemma of having no resources.

preparation example Construction

[0028]Simultaneously, the present invention also provides a kind of preparation method of snow-melting asphalt mixture modifier, and described preparation method comprises the following steps:

[0029] A. Add 80-90 parts by weight of seawater into the heating tank, heat to 40-60°C, and stir for 5-10 minutes;

[0030] B. After the stirring is completed, put 1 to 10 parts by weight of the porous material into the heating tank and soak for 20 to 80 minutes;

[0031] C. Filter out seawater, put the residue into an oven, and dry at 80-100°C for 1-5 hours to obtain a dried porous material;

[0032] D. Preheat the waste oil of 0-20 parts by weight to 100-140° C., immerse the dried porous material obtained in step C in the waste oil, stir for 10-30 minutes, and then filter the waste oil to obtain the obtained Describe snow-melting asphalt mixture modifier.

[0033] The present invention will be further described in conjunction with specific implementation examples below.

Embodiment 1

[0035] In parts by weight, pour 80 parts of seawater with a salinity of 10‰ into the heating tank, heat to 50°C, and stir rapidly for 5 minutes; then stop stirring, and put 5 parts of seawater with a particle size of 1 to 2 mm and a specific surface area of ​​350 to 600m 2 / g, activated carbon particles with a pore size of 1-150nm are immersed in a heating tank for 30 minutes; the seawater is filtered off, the residue is placed in an oven, and dried for 3 hours at 80°C; after that, 15 parts of waste oil are preheated and To 120°C, soak the dried activated carbon particles impregnated with seawater, stir rapidly for 15 minutes; finally filter out the waste oil, and the remaining residue is a new snow-melting asphalt mixture modifier.

Embodiment 2

[0037] In parts by weight, 90 parts of seawater with a salinity of 80‰ was poured into the heating tank, heated to 60°C, and stirred rapidly for 8 minutes; then the stirring was stopped, and 6 parts of seawater with a particle size of 0.01 to 0.5 mm and a specific surface area of 400~780m 2 / g, powdered activated carbon with a pore size of 2-100nm is immersed in a heating tank for 50 minutes; the seawater is filtered off, the residue is placed in an oven, and dried at 100°C for 3.5 hours; after that, 4 parts of waste oil are preheated, and Heat to 100°C, soak the dried activated carbon particles impregnated with seawater, stir rapidly for 20 minutes; finally filter out the waste oil, and the remaining residue is a new snow-melting asphalt mixture modifier.

Abstract

The invention discloses a snow melting bituminous mixture modifier. The modifier is composed of the following components, by weight: 80 to 90 parts of seawater, 1 to 10 parts of a porous material, and 0 to 20 parts of waste oil. The invention also discloses a preparation method for the snow melting asphalt modifier. The modifier provided by the present invention has a stable performance in component composition, and is economic and environmental friendly, simple in the preparation process and preparation equipment, and stable and efficient in usage performance, realizing scientific, rational and effective recycling and reuse of waste resources.

Description

technical field [0001] The invention belongs to the field of asphalt materials, and in particular relates to a snow-melting asphalt mixture modifier and a preparation method thereof. Background technique [0002] The primary requirement for road performance is safety, followed by road performance. Rain, snow, frost, fog and other climatic conditions can seriously endanger road safety. Especially in the cold winter when there is heavy snowfall, the snow on the road not only easily damages the pavement structure, but also causes difficulty in driving, inconvenience in life, and a substantial increase in the rate of traffic accidents. For this reason, various road snow removal equipments have occurred, but these equipments generally have problems such as laborious and time-consuming, and can cause traffic jams and affect the smooth flow of roads. [0003] Therefore, seeking methods and technologies from the road itself is the fundamental way to solve road snow melting. Road c...
