Problems solved by technology

[0002] During the storage and stacking of iron ore powder, due to the dry climate and strong wind, the iron ore powder is easy to form flying dust, which not only seriously pollutes the working environment of the site, causes dust damage to the operators, but also causes the loss of iron ore powder In view of this situation, at present, the method of spreading tarpaulin and covering straw mat on the mineral powder is generally adopted to prevent dust, but spreading tarpaulin and covering straw mat is time-consuming and laborious and the dust-proof effect is general

Abstract

The invention relates to an iron concentrate powder dustproof agent and a preparation method thereof, which relate to a dustproof agent for preventing dust from flying during the transportation and storage of iron concentrate powder. It solves the problem of flying dust generated by iron concentrate powder, polluting the environment, and causing losses; it is composed of water-soluble resin binder, plasticizer, thickener, moisturizing, moisture-absorbing and freezing point-lowering auxiliary agent; its preparation method is: Put the water-soluble resin adhesive into water, heat up to 90°C, stir, and dissolve for 40 minutes, so that all the water-soluble resin adhesive dissolves into a transparent solution; cool down to 66°C, add plasticizer, and then add moisture absorption Dissolve the freezing point additive for 30 minutes; cool down to 60°C and add a thickener to moisturize and absorb moisture; continue stirring for 30 minutes to make the mixture a uniform liquid; cool down to 40°C and filter through a sieve to obtain the finished product . After the dustproof agent of the present invention is sprayed, a reticular film can be formed on the surface of the ore powder, which can effectively prevent the ore powder from flying, improve the environment, reduce the loss of the ore powder, and do not affect the quality of the iron ore concentrate powder.

Description

Technical field: [0001] The invention relates to a chemical product, in particular to a dustproof agent used for dustproofing during transportation and storage of iron concentrate powder and a preparation method thereof. Background technique: [0002] During the storage and stacking of iron ore powder, due to the dry climate and strong wind, the iron ore powder is easy to form flying dust, which not only seriously pollutes the working environment of the site, causes dust damage to the operators, but also causes the loss of iron ore powder In view of this situation, the method of spreading tarpaulin and covering grass mat on the mineral powder is generally used to prevent dust at present, but spreading tarpaulin and covering straw mat is time-consuming and laborious and the dust-proof effect is general. Invention content: [0003] In order to solve the above existing problems, the present invention provides a non-toxic, harmless, non-flammable and explosive water-soluble du...
