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 present invention relates to the preparation of emulsified asphalt pavement external dosage material, and therefore, an environmentally friendly composite snow agent and preparation method thereof and method thereof are made in particular disclosure of emulsified asphalt.The composite fringe salt includes the following raw materials: magnesium acetate, calcium acetate, ethylene glycol, galgin and algae gel.The preparation method is to obtain a mixed solution system of magnesium acetate and calcium acetate and calcium acetate, stirred, dissolved in ethylene glycol, and propanediol, to obtain a mixed solution system; in the mixed solution system obtained above, an algae gel is added, stirredGet environmentally friendly composite snow agents.When it is used, the obtained environmentally friendly composite snow agent is added to the emulsified asphalt, mix stirred, stand, to obtain emulsified asphalt adding an environmentally friendly composite snow agent.

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 deicing agent for emulsified asphalt and its preparation method and use method. 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 prevent freezing. The ice and snow melting agents commonly used in China are mainly salts and alcohols. Alcohols have the phenomenon of anti-icing, and the effect is not good, which leads to a substantial increase in the overall cost; salts are corrosive, easy to corrode and damage road bridge structures and motor vehicles, and also pollute land, water and air, and damage the ecological environment. [0003] At present, the commonly used deicing agents include solid deicing agents and liquid deicing agents. In ad...
