Abstract

The invention discloses a filter material of a dustproof mask, and particularly relates to the field of dustproof masks. The filter material is prepared from the following raw materials in parts by weight: 40 to 60 parts of non-woven fabric, 12 to 20 parts of acid tetraisopropyl ester, 2 to 6 parts of stannic chloride, 0.5 to 3 parts of ammonium fluoride, 30 to 50 parts of ZIF8 material, 4 to 10 parts of polyepichlorohydrin dimethylamine, 60 to 90 parts of polyol, 40 to 75 parts of glyceryl ether, 18 to 40 parts of a precipitant, 0.5 to 4 parts of a bacteriostatic agent, 8 to 15 parts of NaCl particles, 1 to 5 parts of a stabilizer, 20 to 30 parts of hydrogel, and 20 to 30 parts of hydrogel. According to the invention, tetraisopropyl titanate, stannic chloride and ammonium fluoride are introduced into the ZIF-8 material, tin-fluorine co-doped titanium dioxide is generated in situ in pore channels of the ZIF-8 material, harmful substances in the air can be efficiently adsorbed and catalytically degraded, the purpose of efficiently purifying the air is achieved, and by adding NaCl particles and the bacteriostatic agent, NaCl particles can be used for sterilizing bacteria on the mask, and meanwhile bacteria breeding on the mask can be inhibited through the bacteriostatic agent.

Description

technical field [0001] The invention relates to the technical field of dust masks, more specifically, the invention relates to a filter material of a dust mask and a preparation method thereof. Background technique [0002] Dust masks are essential protective equipment for workers engaged in and exposed to dust. It is mainly used in working environments containing low concentrations of harmful gases and vapors and in working environments that generate dust. Only adsorbent or sorbent is contained in the poison filter box. Some filter boxes are also equipped with a filter layer, which can prevent aerosols at the same time. Some military gas masks are mainly made of activated carbon cloth, or use water-resistant and oil-resistant fabric as the outer layer, glass fiber filter material as the inner layer, and polyurethane foam soaked in activated carbon as the bottom layer, which can provide temporary protection against sudden poisonous gas attacks. protection. [0003] There...
