Abstract

The invention discloses an environment-friendly slow-release snow-melting agent, a preparation method thereof and application of the snow-melting agent in a micro-surfacing mixture, and aims to solve the technical problems that an existing snow-melting agent is large in side effect, and an existing micro-surfacing mixture is single in pavement performance and insufficient in wear resistance and high-temperature stability. The environment-friendly slow-release snow-melting agent is prepared from the graphene microchips, the white carbon black, the sodium carbonate, the sodium acetate, the calcium acetate, the surface treating agent and the like, is used for modifying the emulsified asphalt and is applied to a micro-surfacing mixture, has the effects of repairing an old pavement, preventing a new pavement from cracking and actively melting ice and snow, and is excellent in pavement performance; in the whole service period, the ice and snow removing effect, the high and low temperature performance and the abrasion resistance are good, and good economic benefits and social benefits are achieved.

Description

technical field [0001] The invention relates to the technical field of concrete building materials, in particular to an environmentally friendly slow-release deicing agent, its preparation method and its application in micro-surface mixtures. Background technique [0002] Ice and snow disasters occur frequently in northern my country in winter. In terms of transportation, the accumulation of ice and snow will reduce the skid resistance of the road surface and bring safety hazards to the operation of vehicles. At present, in most cases, traditional ice and snow removal methods such as artificial or salting are still used in various places, and there is a lack of more powerful and timely snowmelt measures. [0003] However, in the actual deicing process, the speed of directly spreading industrial salt (which will corrode the road and damage the surrounding ecological environment) and manual machinery to deicing and snowing is slow, which will affect the smoothness of traffic;...
