Abstract

The invention discloses a macromolecular cohesive dust suppressant for suppressing dust in stacking and transportation processes of waste corncobs and corn straws and a preparation method of the macromolecular cohesive dust suppressant. The macromolecular cohesive dust suppressant comprises 0.5%-1.0% of gelatinized starch, 1%-2% of polyacrylamide, 2%-4% of borax, 0.01%-0.02% of an antifreeze agent, 0.01%-0.02% of a surfactant and the balance of water. The anti-freezing agent is monododecyl phosphate potassium; and the surfactant is sodium dodecyl sulfate. After being sprayed, the dust suppressant is combined with plant fibers to cover dust, a compact adhesive film is formed on the surface, the dust suppressant forms a hard shell together with the dust and the fibers after being dried and hardened, the dust suppressant has the advantages of being non-toxic, environmentally friendly, low in price, biodegradable and the like, and secondary environmental pollution is avoided. And after a hard shell is formed on the surface, the surface has wind erosion resistance, rain erosion resistance and freeze thawing resistance, and meanwhile, the production operation is not influenced.

Description

Technical Field

[0001] The present invention relates to the field of polymer environmental protection technology, and is mainly aimed at dust suppression during the stacking and transportation of agricultural waste corn cobs and corn stalks, and in particular to a polymer condensation and bonding dust suppressant and a preparation method thereof, and more specifically to a polymer condensation and bonding dust suppressant and a preparation method thereof for dust suppression during the stacking and transportation of waste corn cobs and corn stalks. Background Art

[0002] With the research on waste utilization and development in recent years, industrialization has gradually taken shape, especially in the field of agricultural waste, which has been used to process organic chemicals, biofuels, biofertilizers, planting materials, etc. Although it has reduced the phenomenon of littering and burning of agricultural waste and created additional income for farmers, the dust pollution caused by transportation, storage and processing has a serious impact on the urban environment. In this process, a large amount of dust will inevitably be generated. These fine dusts are spread by the wind, casting a layer of "dust yarn" on the environment near the factory. The dust dispersed in the wind has caused great trouble to the people passing by, and living in such an environment for a long time will have an extremely adverse effect on people's health.

[0003] At present, the main methods of preventing dust include sprinkling water and covering with dust-proof nets. However, the dust suppression effect of sprinkling water is short-lived, which will have a great impact on the use of raw materials and cause a waste of water resources. Covering with dust-proof nets has a poor effect on suppressing fine dust, and the implementation effect is limited by the size of the gauze. It is also extremely inconvenient for workers who frequently work on material piles, and the cost is high. Waste thatched nets will also cause secondary pollution to the environment.

[0004] Therefore prior art needs further improvement and development. Summary of the invention

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art and to provide a polymer cohesive bonding dust suppressant and a preparation method thereof, so as to achieve the environmental protection performance of the dust suppressant and improve the dust suppression efficiency.

[0006] In order to solve the above technical problems, the present invention adopts the following compatibility and method: A high molecular weight cohesive dust suppressant for suppressing dust during the stacking and transportation of waste corn cobs and corn stalks, which comprises the following components in terms of weight percentage: 0.5%-1.0% gelatinized starch, 1%-2% polyacrylamide, 2%-4% borax, 0.01%-0.02% antifreeze agent and 0.01%-0.02% surfactant, and the balance is water.

[0007] The aforementioned high molecular cohesive bonding dust suppressant is characterized in that: the antifreeze agent is potassium monododecyl phosphate; and the surfactant is sodium dodecyl sulfonate.

[0008] A method for preparing a polymer condensation-bonding dust suppressant for suppressing dust during the stacking and transportation of waste corn cobs and corn stalks, characterized in that it comprises the following steps: Step 1, dissolving gelatinized starch and polyacrylamide in water respectively according to a proportion, mixing them together after being evenly dissolved, adding borax according to a proportion, stirring and reacting at 60° C.-80° C. for 1 hour-2 hours to obtain a first solution; Step 2: Add the active agent to the first solution according to the proportion, stir and react at 60° C.-80° C. for 1 hour-2 hours to obtain a second solution.

[0009] When in use, the solution is loaded into the spray equipment and sprayed on waste such as corn cobs to inhibit the generation of dust and achieve the purpose of environmental protection.

[0010] The invention has the advantages of low cost, no secondary pollution to the environment, obvious dust suppression effect and long covering time. DETAILED DESCRIPTION
