[0097] According to a second aspect of the present invention, a kind of preparation method of dust suppressant is provided, comprising the following steps:
[0098] The dust suppression agent is obtained by mixing the crusting agent, auxiliary dispersant, water and optional auxiliary materials.
[0099] The preparation method of the dust suppressant of the present invention is simple and easy, easy to operate and control, has low energy consumption and low cost, and is very suitable for industrialized production.
[0100] Preferably, the preparation method of dust suppressant comprises the following steps:
[0101] (a) adding the formula amount of crusting agent into part of water at 50-70°C in batches to obtain solution A;
[0102] (b) adding the auxiliary dispersing agent of formula quantity into remaining water in batches to obtain solution B;
[0103] (c) solution A and solution B are mixed in batches, and optional auxiliary materials are added and mixed to obtain a dust...
Embodiment 1
[0131] A dust suppressant, by weight percentage, comprising:
[0132] Sodium alginate 1.5%, Brij35 0.3%, pH regulator hydrochloric acid 0.05%, defoamer (DF568) 0.05%, water balance;
[0133] The preparation method of dust suppressant comprises the following steps:
[0134] (1) Take 80% by weight of water and heat it to a constant temperature of 50-70°C, add sodium alginate in 10 batches under mechanical stirring, and stir until there is no solid or viscous substance in the solution before adding the next batch of seaweed Sodium alginate continues to stir, obtains sodium alginate solution;
[0135] (2) To maintain a constant temperature, another Brij35 was added to the remaining 20% by weight of water, stirred until dissolved, and left to stand until the foam disappeared to obtain a Brij35 solution;
[0136] (3) Add the sodium alginate solution into the Brij35 solution in 10 batches under stirring. After each addition, stir until homogeneous and the foam fades before adding...
Embodiment 2
[0138] A dust suppressant, by weight percentage, comprising:
[0139] Sodium alginate 0.15%, Brij35 5%, pH regulator sodium carbonate 0.1%, defoamer (DF568) 0.1%, water balance;
[0140] The preparation method of dust suppressant comprises the following steps:
[0141] (1) Take 80% by weight of water and heat it to a constant temperature of 50-70°C, add sodium alginate in 10 batches under mechanical stirring, and stir until there is no solid or viscous substance in the solution before adding the next batch of seaweed Sodium alginate continues to stir, obtains sodium alginate solution;
[0142] (2) To maintain a constant temperature, another Brij35 was added to the remaining 20% by weight of water, stirred until dissolved, and left to stand until the foam disappeared to obtain a Brij35 solution;
[0143] (3) Add the sodium alginate solution into the Brij35 solution in 10 batches under stirring. After each addition, stir until homogeneous and the foam fades before adding the...
