Embodiment 1

[0051] Example 1 In the synthetic polymer medical glue sodium polyacrylate, add coagulant 2% starch-grafted sodium polyacrylate, and coat it on the non-woven fabric by known method.

Embodiment 2

[0052] Example 2 In the natural fibrin bio-glue, add 3% sodium acrylate, and coat it on the non-woven fabric by known method.

Embodiment 3

[0053] Example 3 Test effect

[0054] In this experiment, a quantitative commercially available mosquito coil is burned in a simulation device (using a transparent glass bottle) to generate a certain concentration of smoke to simulate the smoke aerosol. After obtaining a certain concentration of smoke, paste Example 1 in the simulation bottle. of The polymer double-sided adhesive sheet is immediately sealed with a plastic film, and the photo is taken to obtain an opaque photo of the smoke in the bottle; the Tyndall phenomenon unique to the aerosol can be observed by illuminating the smoke with a light source. Continue to observe:

[0055] (1) Through the bottle, it can be observed that the smoke is getting smaller and smaller. After 15 minutes, the last photo is taken to get a transparent photo;

[0056] (2) Take out the adsorption sheet and find that the color becomes darker, there is a smell of thick smoke, and there are tiny smoke dust stuck on it;

[0057] (3) Tyndall...

Abstract

The invention discloses a novel anti-haze mask, wherein a binding agent layer absorbent sheet is arranged on the outer layer or inner core of the mask; and the binding agent layer absorbent sheet is made by coating a binding agent on a non-woven fabric or a cotton fabric or silks, which serve as a substrate material, and covering the substrate material with reticular fibers. On the basis of bionic thought, the binding agent layer absorbent layer can promote the coagulation of aerosol, so that the aerosol is turned into large particles, and various particles in air can be bound. The anti-haze mask, which is novel, efficient and cheap, plays an important role in protecting people's health.

Description

technical field [0001] The invention relates to a novel anti-fog and haze mask, which belongs to the technical field of sanitary protection products. Background technique [0002] In recent years, smog weather has appeared all over the country, and it continues to happen in some areas. Smog belongs to atmospheric aerosol, which is composed of solid or liquid small particles (0.001-0.1 micron) suspended in gas. Particles with a diameter less than or equal to 2.5 microns are commonly known as PM2.5. Haze is dry aerosol particles, and fog is cloud droplets with aerosol particles. The chemical composition of aerosol is very complex, it contains various trace metals, inorganic compounds and oxygen-containing organic compounds, etc. PM2.5 has a small particle size and cannot be blocked by the respiratory tract. It can penetrate deep into the terminal bronchioles and alveoli, and deposit in the alveoli, unable to be discharged, affecting the gas exchange in the lungs. Long-term ...
