AI Technical Summary

Problems solved by technology

However, the method is only suitable for low-concentration methane gas, and requires the performance of a directional film blow-up detector at a higher flow rate, which is not suitable for actual mine protection
[0007] To sum up, there are no reports about the use of MXene materials in protective equipment for monitoring toxic gases in mines

Embodiment 1

[0081] This embodiment discloses figure 1 The preparation process of the main protective fabric shown is as follows:

[0082] Such as figure 1 As shown, the main protective fabric includes an antistatic breathable base cloth layer 1, an MXene-based filter layer 2 and an antistatic hydrophobic layer 3 from the inside to the outside, and the preparation process of each layer is as follows:

[0083] Ti 3 C 2 T x Material preparation: the precursor material Ti was etched with a mixed solution of LiF and HCl (32wt%) with a mass ratio of 3:7 3 AlC 2 Medium element Al, the temperature is 30°C, and the reaction time is 60h. After the reaction is fully completed, centrifuge at 3500 rpm for 4 times until neutral, and the two-dimensional layered Ti can be obtained. 3 C 2 T x Material.

[0084] Prepare antistatic breathable base cloth layer: get each mass ratio and be respectively bamboo fiber: flax: ice silk=4:1:3 component weaves blended yarn, gets part blended yarn and above-m...

Embodiment 2

[0089] This embodiment discloses figure 2 The preparation process of the protective fabric with good bactericidal effect shown is as follows:

[0090] Such as figure 2 As shown, the main protective fabric consists of an antistatic breathable base fabric layer 1, an MXene-based filter layer 2, an antistatic hydrophobic layer 3, and a bactericidal layer 4-1 from the inside to the outside, and the preparation process of each layer is as follows:

[0091] Take Ti at a concentration of 0.5 mg / mL 3 C 2 T x The solution is mixed with the silver nanowire bactericide of 2 mg / mL to form a uniformly dispersed mixed solution, and the mixed solution is sprayed on the surface of the main body protective fabric prepared in Example 1, and after drying, a bactericidal layer with a thickness of 1 mm is obtained and has a good bactericidal effect. Protective fabric.

[0092] Wherein, the mixed liquid can also be 10 mg / mL hexagonal boron nitride and 10 mg / mL silver nanowire fungicide.

Abstract

The invention discloses a mine protective clothing fabric with synergistic functions of antibacterial, antistatic, toxic gas monitoring and dust and poison filtration and a preparation method thereof. The protective clothing fabrics include main protective fabrics, sterilization protective clothing fabrics and aerochromic protective clothing fabrics, wherein the main protective clothing fabrics include base fabrics treated with MXene conductive, MXene filtration surfaces containing hydrophilic functional groups that can react with mine toxic gases layer and wear-resistant antistatic hydrophobic layer, the main protective fabric is used as the main body of the protective clothing. The functional fabric modified with dispersant and silver nanowire bactericide is used in the neckline, cuffs, etc. of protective clothing, which is easy to breed bacteria, which can effectively kill bacteria; When the gas-sensitive discoloration layer encounters the harmful gas in the mine, the color changes significantly, which can alert the mining staff and ensure the safety of the mine operation.

Description

technical field [0001] The invention relates to a protective clothing fabric for mines, belonging to the technical field of textile materials, in particular to a mine protective clothing fabric with synergistic functions of antibacterial, antistatic, toxic gas monitoring and dust filtration and a preparation method thereof. Background technique [0002] my country is one of the countries with strong coal resources, and the number of coal miners is also the largest in the world. However, the underground operation of coal mines is a kind of work with a special environment. Due to the influence of the geological environment, the working conditions of most coal sites are poor, dark, humid, and the working face is narrow. , is also accompanied by the constant threat of five natural disasters such as gas, coal dust, water, fire, and roof. Therefore, in order to protect the safety of the majority of coal mine employees, it is particularly important to use protective equipment that ef...
