Embodiment 1

[0032] A dust-suppressing antifreeze solution for railway coal transportation, which comprises by weight: 40 parts of anhydrous calcium chloride; 4 parts of magnesium hexafluorosilicate; 9 parts of ethylene glycol; 15 parts of glycerin; 5 parts of hydroxypropyl methylcellulose ; Preservatives 2 parts. Wherein, the preservative includes: 1 part of triethanolamine; 0.3 part of benzotriazole; and 0.7 part of sodium silicate.

[0033] The preparation method of railway coal transportation dust suppression antifreeze described in the present embodiment comprises:

[0034] Step 1: Add specified weight parts of benzotriazole and sodium silicate to pure water, and stir until they are completely dissolved in pure water;

[0035] Step 2: Add specified parts by weight of anhydrous calcium chloride and magnesium hexafluorosilicate to the solution in Step 1 and stir until they are completely dissolved;

[0036] Step 3: Add specified weight parts of ethylene glycol, glycerol and triethanol...

Embodiment 2

[0040] A dust-suppressing antifreeze solution for railway coal transportation, which comprises by weight: 45 parts of anhydrous calcium chloride; 6 parts of magnesium hexafluorosilicate; 16 parts of ethylene glycol; 20 parts of glycerin; 12 parts of hydroxypropyl methylcellulose ; 6 parts of preservatives. Wherein, the preservative includes by weight: 3.2 parts of triethanolamine; 1.6 parts of benzotriazole; and 1.2 parts of sodium silicate.

[0041] The preparation method of the dust-suppressing antifreeze for railway coal transportation described in this embodiment is the same as the preparation method in Embodiment 1.

Embodiment 3

Abstract

The invention relates to dust-suppression anti-freezing liquid for railway coal transportation. The dust-suppression anti-freezing liquid is prepared from the following components in parts by weight:40 to 45 parts of anhydrous calcium chloride, 4 to 6 parts of magnesium silicofluoride, 9 to 16 parts of ethylene glycol, 15 to 20 parts of glycerin, 5 to 12 parts of hydroxypropyl methyl cellulose, and 2 to 6 parts of a preservative. The dust-suppression anti-freezing liquid has the advantages that by improving on the basis of anti-freezing liquid, the dust-suppression function, viscosity, moisturizing degree and adhesion force are increased, the decomposing degree and volatizing degree are reduced, the user property is improved, and the defects and disadvantages of the original product are overcome.

Description

technical field [0001] The invention relates to the technical field of cargo transportation protection, in particular to a dust-suppressing antifreeze liquid for railway coal transportation. Background technique [0002] During coal transportation, dust caused by air flow and turbulence of transportation tools will cause serious air pollution, and also cause cargo loss and economic loss; During the storage or transportation of railways, it is very easy to freeze, freeze in the car and freeze in the carriage, causing difficulties in loading and unloading cars, affecting vehicle turnover and transportation efficiency, and causing economic and benefit losses to both the supply and demand sides. [0003] The Ministry of Railways of the People's Republic of China stipulates that when transporting bulk kueh granule goods on the northern railway, the goods must be sprayed with TB / T3208-2008 "Antifreeze for Bulk Granular Cargo Transport" after loading, and TB / T3210.1-2009 "Bulk Gran...
