preparation example Construction

[0052] The embodiment of the invention also discloses a preparation method of an anti-icing sealing layer material containing sand mist. Specifically, the preparation method includes the following steps:

[0053] The raw materials are evenly mixed to obtain the anti-icing and sand mist sealing layer material.

[0054] Wherein, the anti-icing and sand-mist sealing layer material is the anti-icing and sand-mist sealing layer material of the above-mentioned embodiment. Therefore, the raw materials of the anti-icing and sand mist sealing layer material include the following components in parts by weight: 20-40 parts of anti-icing agent, 100 parts of emulsified asphalt, 15-30 parts of thickening mixed solution and 40 parts of aggregate ~60 servings. Wherein, the anti-icing agent is composed of ice-melting salt and a hydrophobic agent, and the hydrophobic agent is coated with the ice-melting salt.

[0055] The preparation method of each raw material of the anti-icing and sand-mis...

Embodiment 1

[0062] Embodiment 1 specifically prepares the anti-condensation ice-containing sand mist sealing layer material through the following process:

[0063] (1) Weigh 110g of sodium chloride and disperse it in 200g of water, stir well to obtain an ice-melting saline solution. Add 160 g of dried diatomaceous earth into the ice-melting saline solution, and stir and disperse with a disperser at 600 r / min and 55° C. for 12 hours to obtain the first mixture. Then put the first mixture in a vacuum drying oven at 90°C, and dry the first mixture to a constant weight under the condition of a vacuum of -0.04 to -0.06MPa, take it out and grind it until it passes through a 100-mesh sieve to obtain a molten ice aggregate.

[0064] (2) Add 10 g of isobutyltriethoxysilane to 100 g of n-butanol to obtain an organic solution of a hydrophobic agent. Then add 200 g of the ice-melting aggregate obtained in the above step (1) into the organic solution of the hydrophobic agent, stir evenly with a disp...

Embodiment 2

[0078] Example 2 The anti-icing and sand mist sealing layer material is specifically prepared through the following process:

[0079] (1) Take by weighing 136g of magnesium chloride and disperse it in 200g of water, stir to obtain the ice-melting saline solution. Add 180 g of dried fly ash into the ice-melting brine solution, and stir and disperse with a disperser at a speed of 600 r / min at 50° C. for 12 hours to obtain the first mixture. Then place the first mixture in a vacuum drying oven at 90°C, and dry the first mixture to constant weight under the condition of vacuum degree of -0.04 ~ -0.06MPa, take it out and grind it until it passes through a 100-mesh sieve to obtain a molten ice aggregate.

[0080](2) Add 10 g of silane / siloxane concentrate (Z-6689 produced by Dow Corning) to 100 g of ethanol to obtain an organic solution of the hydrophobic agent. Then add 200 g of the ice-melting aggregate obtained in the above step (1), stir evenly with a disperser, and leave it o...

Abstract

The embodiment of the invention discloses an anti-icing sand-containing fog seal layer material and a preparation method thereof. Raw materials for preparing the anti-icing sand-containing fog seal layer material comprise, by weight, 20-40 parts of an anti-icing agent, 100 parts of emulsified asphalt, 15-30 parts of a thickening mixed solution and 40-60 parts of aggregates, wherein the anti-icingagent is composed of an ice melting salt and a hydrophobic agent, and the ice melting salt is coated with the hydrophobic agent. In the embodiment of the invention, the special anti-icing agent treated with the hydrophobic agent is used, so demulsification of the emulsified asphalt is avoided during mixing the anti-icing agent with the emulsified asphalt; and additionally, the emulsified asphalt having thickening and sand-suspending effects is used as a matrix, so the anti-icing agent is stably dispersed in the anti-icing sand-containing fog seal layer material as the filler, thereby the uniformity and the application property of the anti-icing sand-containing fog seal layer material are guaranteed.

Description

technical field [0001] The invention relates to the technical field of sand mist-containing sealing layer materials, in particular to an anti-condensation ice-containing sand mist sealing layer material and a preparation method thereof. Background technique [0002] Anti-icing technology is an active deicing technology applied to asphalt pavement. It can suppress the freezing of road surface or reduce the adhesion between ice and road surface by mixing or covering ingredients in pavement materials that can lower the freezing point. It can effectively guarantee the safety and smoothness of traffic during the ice and snow season. Compared with traditional methods such as spreading deicing agents, manual and mechanical removal methods, spreading sand and gravel materials, and thermal melting of ice and snow, this method has the advantages of environmental protection, high efficiency, energy saving, and low price, and has been widely concerned and applied by the road maintenance...
