Manufacturing method of environment-friendly snow/ice melting composition

Abstract

The invention discloses a manufacturing method of an environment-friendly snow / ice melting composition, which comprises the following steps: manufacturing a snow melting A, manufacturing a ray absorbent B and manufacturing a long-acting additive C. The composition comprises the following components in percentage by mass: 50ppm-2% of ray absorbent B and 200ppm-2% of long-acting additive C and the balance of snow melting agent A. The application range of the composition is 0--60 DEG C, and the snow melting property can be adjusted according to demands. The snow / ice melting composition can fully utilize solar energy and waste heat emitted by vehicles running on the road, has long effective acting time of snow / ice melting, and does not damage the pavements, buildings and metal box plants; and the molten water can satisfy the biological oxygen demand index in Natural Discharge Standard. The composition is simple in production technique, convenient to use and easy for popularization.

[0002] Snow or ice on the road often causes great inconvenience and safety hazards to travel

Snow or ice at the airport often makes the airport temporarily closed and delays the flight; snow or ice on the expressway will also lead to the speed limit of the expressway, and part of it will be closed; and the snow or ice on the urban road will slow down the traffic flow and congest. It will also seriously affect the safety of pedestrians

Obviously, snow or ice has a great negative impact on people's travel and goods transportation

[0003] In order to deal with snow and icing, there are three commonly used methods: one is to use a lot of manpower and material resources to implement snow removal or deicing on the road surface manually or mechanically, but this will cause different degrees of damage to the road surface , and the damage will gradually cause large-area damage to the road surface under the repeated action of rain erosion, temperature changes in four seasons and road loads; on the other hand, it takes a long time and the efficiency is very low

The second is to lay heating cables under the road surface, or directly use conductive concrete, which is still under study. It is also considered to re-lay a conductive fiber layer on the road surface for heating, and to control snow accumulation through the conversion of electric energy and heat energy. On the one hand, it will lead to a sharp increase in the cost of road construction, but the utilization rate of the facilities is relatively low (only used in winter in a year), causing a lot of waste and not applicable to the roads and airports that have been built; on the other hand On the one hand, it also consumes a lot of power when using

But it will cause the biological oxygen demand (BOD) of the water body to rise in the water
