Embodiment 1

[0019] The preparation of titanium dioxide nanoparticle modified polyurethane sponge mask material: after getting 100 parts by weight of polyether polyols with a molecular weight of 3050, 1 part by weight of silicone oil, 0.4 parts by weight of stannous octoate, 0.2 parts by weight of triethylenediamine and 4.6 parts by weight of water, Mix together and stir evenly, add 2 parts by weight of nano-titanium dioxide, high-speed mechanical stirring and ultrasonic dispersion, add 45 parts by weight of 2,4-toluene diisocyanate after degassing, stir with a mechanical stirrer at high speed for 6-8 seconds, and quickly pour into the foaming mold foaming in a constant temperature environment of 28°C, and demolded after aging for 24 hours, the nano-particle modified polyurethane sponge material was obtained. Adopt saturated adsorption method to measure the amount of this sponge material adsorption nano-dust, it is 2.1 times of unmodified polyurethane sponge material adsorption nano-dust am...

Embodiment 2

[0021] The preparation of magnetic iron ferric oxide nanoparticles modified polyurethane sponge mask material: get 100 parts by weight of polyether polyol with a molecular weight of 3050, 1 part by weight of silicone oil, 0.5 part by weight of stannous octoate, 0.25 parts by weight of triethylenediamine and 5 parts by weight of water. After the parts by weight, mix together and stir evenly, and add 2 parts by weight of magnetic iron ferric oxide nanoparticles, high-speed mechanical stirring and ultrasonic dispersion, add 45 parts by weight of 2,4-toluene diisocyanate after degassing, and stir with a mechanical stirrer at high speed After 6-8 seconds, quickly pour it into a foaming mold, foam in a constant temperature environment of 28°C, and release it after aging for 24 hours to obtain the magnetic nanoparticle modified polyurethane sponge mask material. Adopt saturated adsorption method to measure and show: the amount of this sponge material adsorption magnetic nanometer dust...

Embodiment 3

[0023] The basic dimensions of the mask are determined by referring to the No. 13 nose depth and opening size of the Chinese standard head type: the length is 130mm, the width is 110mm, and the depth (height) is 25mm. Prepare the mask mold according to this size.

Abstract

The invention provides an inorganic nanoparticles-modified polyurethane sponge mask material and a preparation method thereof, and also provides application of the inorganic nanoparticles-modified polyurethane sponge mask material in manufacturing a mask. In the invention, the inorganic nanoparticles used for modifying sponge comprise magnetic Fe3O4 nanoparticles, magnetic Fe2O3 nanoparticles, TiO2 nanoparticles, ZnO nanoparticles, mesoporous SiO2, carbon nanotubes and carbon fibers. The inorganic nanoparticles have the advantages of small particle size, large specific surface area, strong adsorption performance and like and contain charges on the surfaces, and a plurality of the nanoparticles have strong ultraviolet absorption capability, photocatalytic activity, and antibacterial and antiviral actions. The inorganic nanoparticles-modified polyurethane sponge mask material provided by the invention has high efficiency and capability in filtering out sub-micron dust, viruses and bacteria, has the function of adsorbing poisonous and harmful gases, has the characteristics of small gas absorption resistance, simple preparation method, low cost and broad application future, and can be recycled through water washing.

Description

Technical field: [0001] The invention belongs to the technical field of labor protection products, and in particular relates to mask materials in the technical field of health care. Background technique: [0002] The smaller the diameter of dust in the air, the deeper it enters the respiratory tract. Dust with a diameter of less than 2 microns can directly enter the capillaries and alveoli 100%, so dust with a small diameter, especially nanometer to submicron dust, is harmful to human health. bigger. In addition, other pollutants in indoor air such as cigarette smoke, formaldehyde released by various decoration materials, organic volatiles, mold, spores, bacteria, viruses, fibers, etc. will also have adverse effects on human health. In buildings without air filters and industrial and mining enterprises with a lot of dust, air pollution can be avoided by using masks. [0003] There are many types of mask materials that have applied for relevant patents, but their functions ...
