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.

Description

technical field

[0001] The invention belongs to the fields of transportation and disaster prevention, and relates to a composition for removing snow or anti-icing, in particular to a preparation method of an environment-friendly snow-melting and ice-melting composition. Background technique

[0002] Snow or ice on the road often causes great inconvenience and potential safety hazards for 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 icing has had a great negative impact on people's travel and cargo 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 resource...

Examples

Embodiment 1

[0025] Deicing agent A, sodium nitrate 98.0g; radiation absorber B, naphthol green B0.1g; long-acting additive C, cellulose carboxymethyl ether 1.9g. Add 100.0g of water in turn, stir evenly, and use it as a liquid.

Embodiment 2

[0027] Deicing agent A, urea 85.0g, ferric chloride 12.0g; radiation absorber B, naphthol green B0.2g; long-acting additive C, polyvinylpyrrolidone 2.8g. Add 80.0g of water in turn and stir evenly. Evaporate the water, grind and pass through a 30-mesh sieve to obtain powder for use.

Embodiment 3

[0029] Deicing agent A, ammonium nitrate 90.0g, potassium acetate 7.0g; radiation absorber B, phthalocyanine 0.1g; long-acting additive C, diamine phosphate 2.9g. Add 300.0g of water in turn and stir evenly.
