Problems solved by technology

In addition to polluting the environment, solid deicing agents also have other disadvantages during use, which are mainly manifested in the following aspects: First, when the solid deicing agent is spread, the road surface is slippery, and the waste caused by popping out of the road surface, splashing into the road shoulder and drainage system Extremely large, coupled with the influence of the wind, the waste ratio is as high as 30%; the second is that when the dry snow melting agent is spread on the snow, it needs to absorb heat and moisture to form a saline solution, lower the freezing point, and play the role of melting snow and ice. Before the particles absorb enough heat and moisture, they cannot react chemically and cannot melt ice and snow; third, solid deicing agents usually cannot be preheated like liquid deicing agents, and it takes a long time to melt ice and snow, especially at high temperature. in lower climates

Abstract

The invention relates to the field of preparation of emulsified asphalt pavement additive materials, and particularly discloses an environment-friendly composite snow-melting agent for emulsified asphalt, and a preparation method and an application method of the environment-friendly composite snow-melting agent. The composite snow-melting agent comprises magnesium acetate, calcium acetate, glycol, glycerol and alga gel. The preparation method includes mixing the magnesium acetate with the calcium acetate, stirring the mixture, and dissolving the mixture in a mixed solution of the glycol and the glycerol to obtain a mixed solution system; adding the alga gel into the obtained mixed solution system, and stirring the mixed solution system to obtain the environment-friendly composite snow-melting agent. During use, the obtained environment-friendly composite snow-melting agent is added into the emulsified asphalt, and the emulsified asphalt with the environment-friendly composite snow-melting agent can be obtained after mixing, stirring and standing.

Description

Technical field [0001] The invention relates to the field of preparation of emulsified asphalt pavement admixture materials, in particular to an environmentally-friendly composite snow melting agent for emulsified asphalt, and a preparation method and use method thereof. Background technique [0002] Snow melting agent, also known as deicing salt and road antifreeze, is mainly used in winter airports, highways, squares, parking railways, urban streets, etc. to remove snow and antifreeze. Commonly used domestic ice and snow melting agents are mainly salts and alcohols. Alcohols have anti-icing phenomenon, which is not effective, leading to a substantial increase in overall costs; salts are corrosive, easily corroding and destroying the structure of roads and bridges and motor vehicles, and also pollute the land, water and atmosphere, and damage the ecological environment. [0003] At present, the commonly used snow melting agents include solid snow melting agents and liquid snow me...
