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

Embodiment 3
[0043] 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:
[0044] S1. Grinding
[0045] First, 28 parts of flax bast fiber, 28 parts of jute bast fiber, 14 parts of sisal leaf fiber, 7 parts of abaca leaf fiber and 5 parts of coconut fruit fiber are separately ground with a grinder, and all are ground into 700-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;
[0046] S2. mix
[0047] 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 5 parts of cornstarch to mix;
[0048] S3. Preparation
