Problems solved by technology

[0004] However, raw materials such as calcium chloride used in this technical scheme, industrial acetic acid waste liquid and wood vinegar contain a large amount of free active ions such as chloride ions and acetate ions. Attached to the surface of the asphalt pavement, it is easy to adhere to the driving tires, resulting in easy loss of snow-melting components, gradually reducing the snow-melting function of the snow-melting asphalt pavement, and affecting the snow-melting durability of the snow-melting asphalt

Embodiment 1

[0034] Embodiment 1: a kind of preparation method of melting snow asphalt comprises the steps:

[0035] (1) Molecular sieve pretreatment: select NaY molecular sieve with a specific surface area of ​​703㎡ / g, crush it into NaY molecular sieve powder with a pulverizer, sieve with a sieve with a pore size of 125 μm, and select a NaY molecular sieve with a particle size not greater than 125 μm powder; weigh 3.5Kg of sodium nitrate, dissolve it in 60Kg of water, add 14Kg of NaY molecular sieve powder with a particle size not greater than 125 μm, stir evenly, dry at 80°C for 100min, and roast at 400°C for 180min to obtain sodium microporous molecular sieve powder;

[0036] (2) Resin pretreatment: select the styrene-divinylbenzene copolymer ion exchange resin containing the tertiary amine group, the styrene-divinylbenzene copolymer ion exchange resin containing the tertiary amine group is Weak base anion exchange resin, pulverized into resin powder with a pulverizer, sieved with a sie...

Embodiment 2-9

[0040] The difference between embodiment 2-9 and embodiment 1 is that the amount of each raw material in embodiment 2-9 is different, and the process parameters are different.

[0041] See Table 1 for the dosage of each raw material in Examples 2-9, and see Table 2 for the process parameters of Examples 2-9.

[0042] The addition of each raw material of table 1 embodiment 2-9

Abstract

The invention discloses snow-melting asphalt and a preparation method thereof, belonging to the technical field of asphalt materials. The snow-melting asphalt is mainly prepared from the following asphalt raw materials in parts by weight: 100 to 150 parts of asphalt, 3 to 10 parts of an epoxy resin adhesive, 1 to 2.5 parts of white carbon black and 3 to 8 parts of diatomite. The asphalt raw materials further comprise a snow-melting aid, and the snow-melting aid is mainly prepared from the following raw materials in parts by weight: 19-26 parts of chloride ion type anion exchange resin and 15-20 parts of sodium type microporous molecular sieve powder. The snow-melting aid has the advantage of capability of reducing the loss of snow-melting components to a certain extent. The preparation method of the snow-melting asphalt comprises the following steps: molecular sieve pretreatment, resin pretreatment, preparation of the snow-melting aid, mixing and dissolving, and the like. The preparation method of the snow-melting asphalt has the advantage that the durability of the product is conveniently improved.

Description

technical field [0001] The invention relates to the technical field of asphalt material processing, in particular to a snow melting asphalt and a preparation method thereof. Background technique [0002] Asphalt pavement is widely used in highways and other fields because of its smooth surface, comfortable driving, low vibration, low noise and wear resistance. However, under extreme weather conditions, especially in rainy and snowy weather, the safety of asphalt pavement is severely challenged. Snow on the road not only easily damages the pavement structure, but also causes difficulty in driving, inconvenience in life, and a significant 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. Therefore, it is necessary to develop asphalt materials with snow melting function. [0003] The application document with the application publi...
