Problems solved by technology

[0004] In the process of coal transportation and storage, the working principle of the dust suppressant is the principle of surface bonding and fixing. After spraying the dust suppressant on the coal surface of the train for a certain period of time, a solidified layer with a certain strength and toughness will be formed on the coal surface to prevent coal To achieve the purpose of dust suppression, the dust suppressant for railway coal transportation should have environmental protection, good cohesiveness, good rain resistance and antifreeze performance, but the existing dust suppressant does not have flame retardancy, Once a fire source is ignited, it is difficult to extinguish, and it is easy to cause a fire, and most flame retardants contain polluting atoms such as halogens, which do not conform to the concept of environmental protection, and the existing dust suppressants have poor adsorption and bonding performance, and are not effective for dust floating in the air. Poor adsorption and solidification of dust and small particles

Abstract

The invention discloses an environment-friendly flame-retardant composite material, which is prepared from the following raw materials in parts by weight: 30 to 50 parts of adsorption resin, 5 to 10 parts of flame-retardant filler, 1 to 3 parts of ammonium polyphosphate, 10 to 20 parts of carboxymethyl starch, 5 to 10 parts of nano cellulose, 60 to 80 parts of acrylic acid, 60 to 80 parts of dimethyl diallyl ammonium chloride, 0.5-1 part of N, N'-methylene bisacrylamide, 60 to 80 parts of glycerol, 130 to 150 parts of absolute ethanol, 1 to 3 parts of ammonium persulfate and 1 part of a coupling agent. The invention also discloses a prepration method of the environment-friendly flame-retardant composite material, and the environment-friendly flame-retardant composite material not only has a compact three-dimensional network structure, and is good in flame retardance and adsorption property, and due to high adhesion, high wettability and wind erosion resistance, the environment can be effectively protected and dust pollution can be effectively reduced when being used in the fields of dust and coal dust treatment.

Description

technical field [0001] The invention belongs to the technical field of preparation of environment-friendly composite materials, and in particular relates to an environment-friendly flame-retardant composite material and a preparation method thereof. Background technique [0002] During the process of coal mining, transportation and storage, a lot of dust will be generated. The dust not only endangers the health of on-site personnel, but also causes environmental pollution, waste of resources, and even safety accidents. [0003] The methods of suppressing dust usually include trimming windshields, covering dust-proof nets, adopting closed structures, sprinkling water, and using chemical dust suppressants, etc. The cost of building windshields is huge, and the effect of dust suppression is limited, and the cost of covering dust-proof nets to suppress dust is high , Easy to drive, easy to cause pollution, and it takes a long time to install and disassemble. The cost of dust su...
