preparation example Construction

[0033] The preparation method of the particulate barrier material is simple, that is, the cationic polymer is dissolved in the solvent as a solute, and mixed evenly, and a cosolvent and a preservative can be optionally added to the particulate barrier material. The cosolvent can help the solute dissolve more uniformly, and the preservative can Enhanced shelf life of particulate barrier materials. The prepared particle barrier material is charged, and by applying the particle barrier material to anti-smog, it can prevent the suspended particles in the air from being inhaled by the human body. As mentioned above, in order to further improve the filtration effect of the particle barrier material on suspended particles, at least one of the anionic polymer and the amphiphilic polymer can also be added as a solute, and dissolved in a solvent together with the cationic polymer to prepare The filter effect of the formed particle barrier material is better.

[0034] Based on the above...

Embodiment 1

[0044] The particle barrier material provided in this embodiment is composed of the following components: 5% polyquaternium salt, 10% ethanol, and the rest is water, which is dissolved and mixed evenly. Spraying the particle barrier material in this embodiment on the mask can improve the filtering effect of the mask and enhance the anti-fog and haze ability of the mask. The filter efficiency of the mask sprayed with the particle barrier material provided in this embodiment to PM2.5 has reached 46.51%.

Embodiment 2

[0046] The particle barrier material provided in this example is composed of the following components: 2% polyquaternium ammonium salt, 0.5% cationic polyacrylamide, 0.1% polymer cationic alkyl polyglucoside, 5% anionic polyacrylamide, 8% ethanol, and the rest For water, dissolve and mix well. Spraying the particle barrier material in this embodiment on the mask can improve the filtering effect of the mask and enhance the anti-fog and haze ability of the mask. The filter efficiency of the mask sprayed with the particle blocking material provided in this embodiment to PM2.5 has reached 95.35%.

Abstract

The invention provides a particulate barrier material and application of the same to haze prevention, belonging to the field of respiration protection articles. The particulate barrier material comprises a cationic polymer which accounts for 0.1 to 10% of the mass of the particulate barrier material. The particulate barrier material has charges and can form a micro-electric protective layer; particulate matters repel macromolecular substances with the same kind of charges as the particulate matters, thereby preventing the macromolecular substances from passing through; the particulate mattersattract macromolecular substances with heterogeneous charges, so large particles are formed through coacervation, and the large particles settle down and are no longer absorbed by the body. The particulate barrier material can enhance the filtering effect of anti-haze materials and anti-haze devices and improve anti-haze effect. In addition, the particulate barrier material can be directly sprayedon the surface of a part in need of haze prevention, such as the face or various anti-haze devices, to produce effective anti-haze effect.

Description

technical field [0001] The invention relates to the field of respiratory protection products, in particular to a particle barrier material and its application in anti-smog. Background technique [0002] In daily life, there are a large number of suspended particulate matter in the air, including inorganic acid salts, such as sulfate, nitrate, ammonium salt, nitrogen oxides, sulfur oxides and other metal salts; organic substances, Such as carbon, alkanes; and aerosols formed by these substances. Particulate matter in the atmosphere is a mixture of solid particulate matter (such as sulfate, sulfide, nitrate, nitrogen oxides, ammonium salts, and other heavy metals) and liquid droplets (including alkanes, polycyclic aromatic hydrocarbons, etc.) in the atmosphere. In haze weather, the suspended particulate matter in the air is particularly serious, seriously endangering health. After the particulate matter enters the body, it will adhere to the respiratory tract, causing bronchi...
