Embodiment 1

[0028] An embodiment of the present invention provides a moisturizing, antifreeze and dust suppressant for coal mines, comprising the following raw materials in parts by weight: 28-32 parts of flax bast fiber, 28-32 parts of jute bast fiber, 13-17 parts of sisal leaf fiber, banana 6-10 parts of hemp leaf fiber, 4-8 parts of coconut fruit fiber, 4-8 parts of corn starch, 1-2 parts of film-forming aid, 2-4 parts of humectant, 1-2 parts of antifreeze, flax bast fiber Raw materials such as jute bast fiber, sisal leaf fiber, abaca leaf fiber, coconut fruit fiber and corn starch are pure natural materials, making dust suppressants more environmentally friendly, and the plant pectin ingredients in the raw materials have good cross-fertilization properties. Cohesion and film-forming properties can make the dust suppressant form a thin film on the surface of the material, which can seal the dust on the surface of the material and play a role in dust suppression, and the film also has wi...

Embodiment 2

[0033] An embodiment of the present invention provides a method for preparing a moisture-retaining antifreeze and dust suppressant for coal mines, comprising the following steps:

[0034] S1. Grinding

[0035] First, 30 parts of flax bast fiber, 30 parts of jute bast fiber, 15 parts of sisal leaf fiber, 8 parts of abaca leaf fiber and 6 parts of coconut fruit fiber are separately ground with a grinder, and all are ground into 600-mesh tiny particles, flax bast fiber, jute bast fiber, sisal leaf fiber, abaca leaf fiber, and coconut fruit fiber are ground into tiny particles with better hygroscopicity, thereby enhancing the hygroscopic effect of the dust suppressant, and Grinding into tiny particles is more conducive to the mixing of subsequent processes;

[0036] S2. mix

[0037] Add the ground flax bast fiber, jute bast fiber, sisal leaf fiber, abaca leaf fiber and coconut fruit fiber into the mixer, and then add 6 parts of cornstarch to mix;

[0038] S3. Preparation

Abstract

The invention provides a moisturizing and anti-freezing dust suppressant for a coal mine, and relates to the technical field of flying dust pollution treatment. The moisturizing anti-freezing dust suppressant for the coal mine comprises the following raw materials in parts by weight: 28-32 parts of flax bast fibers, 28-32 parts of jute bast fibers, 13-17 parts of sisal hemp leaf fibers, 6-10 partsof banana leaf fibers, 4-8 parts of coconut fruit fibers, 4-8 parts of corn starch, 1-2 parts of a coalescing agent, 2-4 parts of a moisturizing agent and 1-2 parts of an anti-freezing agent. The plant pectin component in the raw materials enables the dust suppressant to have excellent crosslinking property and film-forming property; and the dust suppressant can quickly form a layer of film on the surface of the material through the coalescing agent; meanwhile, the plant cellulose component in the raw materials has good moisture absorption and moisture retention effects, the moisture absorption effect is better after the raw materials are ground into small particles, then the moisture retention effect of the dust suppressant can be stronger through the humectant, the freezing phenomenon of the dust suppressant can be prevented through the anti-freezing agent, and the dust suppressant is worthy of vigorous popularization.

Description

technical field [0001] The invention relates to the technical field of dust pollution control, in particular to a moisturizing, antifreezing and dust suppressing agent for coal mines. Background technique [0002] With the rapid rise of my country's economy, the environmental problems caused by the rapid development of industry and the development and utilization of resources have become increasingly severe. Practice has shown that in order to ensure the long-term and sustainable development of my country's economy, it is necessary to solve the current environmental problems. At present, the sources of dust are mainly mining areas, stockpiles, steel plants, construction sites, roads, longwall mining or underground mining areas with continuous mining operations. [0003] Whether it is dust on the ground or in the air, most of them use watering and spraying to reduce dust, but the effect is not ideal, especially in the inland areas of China, where the evaporation is large, and ...
