Problems solved by technology

[0002] In recent years, my country's traffic industry has been booming. At the same time, traffic jams have been caused by snowfall and icing on highways, and a large number of flight delays have been caused by snowfall and icing on airport runways. The formation of an ice layer together brings great difficulty to the cleaning work after snowfall. For this reason, it is mostly solved by spraying deicing agent on a large area in advance when snowfall. There are following defects in this method: 1. It is necessary to spray deicing agent every time before it snows; 2. The amount of deicing agent spraying is relatively large, and the cost is high; Serious corrosion; 4. Pollution to the road surface or the water environment around the airport runway

Abstract

The invention relates to a pavement snow-melting and anti-freezing fog sealing layered material and a manufacturing method thereof. Main components of the fog sealing layered material comprise asphalt, an emulsifier, a low-freezing-point component and a corrosive inhibiter. The fog sealing layered material can be sprayed on various pavements after being manufactured through the manufacturing method. Whether accumulated snow is thick in a relative low temperature situation during snow or after snow, a non-freezing water layer is formed between the pavement and the accumulated snow. With an effect of the non-freezing water layer, accumulated snow on the pavement or an airport runway can be cleaned by a mechanical method or a manual work. The material has not only a characteristic of a fog sealing layer but also a snow-melting and anti-freezing function, is free of any bad influence on concrete, has a waterproof effect on the pavement and can increase nutrition components in plants. In addition, the phosphorous content of the sealing layered material meets a farmland irrigation water quality standard GB5084-92 of our country. Meanwhile, the material can effectively protect the pavement, effectively prevents pavement materials from being lost and reduced and can prolong a service life of the pavement.

Description

technical field [0001] The invention relates to a pavement spray coating material, in particular to a pavement snow-melting anti-condensation ice mist sealing layer material. Background technique [0002] In recent years, my country's traffic industry has developed vigorously. At the same time, traffic jams have been caused by snowfall and icing on roads. Airport runways have caused a large number of flight delays due to snowfall and icing. The formation of an ice layer together brings great difficulty to the cleaning work after snowfall. For this reason, it is mostly solved by spraying deicing agent on a large area in advance during snowfall. This method has the following defects: 1. It is necessary to spray snow melting agent every time before it snows; 2. The spraying amount of snow melting agent is relatively large, and the cost is high; It has serious corrosion effect; 4. It pollutes the road surface or the water environment around the airport runway. Contents of the in...
