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

[0031] At the same time, the present invention also provides a preparation method of an environmentally friendly and stable asphalt mixture modifier for melting snow, the preparation method comprising the following steps:

[0032] A. Preheat the reactor to 60-100°C, add 10-40 parts by weight of animal and vegetable oil, and stir for 5-10 minutes;

[0033] B. Add 0.1 to 5 parts by weight of inorganic salt, and stir for 10 to 30 minutes;

[0034] C. Add 60 to 90 parts by weight of porous materials, stir for 30 to 60 minutes, and then let stand for 30 to 60 minutes to obtain a mixture composed of animal and vegetable oils, inorganic salts and porous materials;

[0035] D. removing the animal and vegetable oils in the mixture obtained in step C, and finally obtaining the environment-friendly and stable asphalt mixture modifier for melting snow.

[0036] The method for removing the animal and vegetable oils in the mixture obtained in step C is as follows: put the mixture into a se...

Embodiment 1

[0039] Preheat the reaction kettle, preheat the temperature of the reaction kettle to 80°C, add animal and vegetable oil (selected from the oil processed and refined from the greasy floating matter in the sewer) in a proportion of 30 parts by weight, stir rapidly for 6 minutes; then add 2 parts of vegetable ash , stirring rapidly for 15 minutes; then the diameter ranges from 0.5 to 500 μm, the micropore diameter ranges from 1 to 100 nm, and the specific surface area is 800 m 2 The powdered activated carbon particle / g is added, and the addition amount is 68 parts, stirs rapidly 60min, then stops stirring, and naturally stands still for 50min; Next, put the mixture into a settling centrifuge tank, and centrifuge for 7min at a speed of 5000r / min; finally filter The oil processed and extracted from the greasy floating matter in the sewer is removed from the mixture, and the remaining sediment is an environmentally friendly and stable asphalt mixture modifier for snow melting.

Embodiment 2

[0041] Preheat the reaction kettle, preheat the temperature of the reaction kettle to 100°C, add animal and vegetable oil (selected from the oil processed and refined from low-quality poultry fat) in a proportion of 40 parts by weight, and stir rapidly for 9 minutes; then add 2.5 parts of vegetable ash, quickly Stir for 15 minutes; then the diameter ranges from 0.5 to 1mm, the micropore diameter ranges from 2 to 40nm, and the specific surface area is 400m 2 Add 57.5 parts of mesoporous alumina particles per gram, stir rapidly for 40 minutes, then stop stirring, and let it stand naturally for 40 minutes; then put the mixture into a sedimentation centrifuge tank, and centrifuge for 6 minutes at a speed of 6000r / min; Finally, the oil processed and extracted from poor-quality poultry fat in the mixture is filtered off, and the remaining sediment is the prepared environmental-friendly and stable asphalt mixture modifier for melting snow.

Abstract

The invention discloses environment-friendly and stable asphalt mixture modifier for melting snow. The modifier comprises the following components in part by weight: 60 to 90 parts of porous material, 10 to 40 parts of animal and vegetable oil and 0.1 to 5 parts of inorganic salt. The invention further discloses a preparation method of the environment-friendly and stable asphalt mixture modifier for melting the snow. The modifier provided by the invention has the advantages of stable composition performance of the components, economy, environmental friendliness, simple preparation process and preparation equipment, and stable and efficient use performance, and realizes scientific, reasonable and effective recovery and reuse of waste resources.

Description

technical field [0001] The invention belongs to the field of asphalt materials, and in particular relates to an environment-friendly and stable asphalt mixture modifier for melting snow 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 w...
