Protein virus protection barrier biological agent and preparation method

Abstract

The invention discloses a preparation method of a protein virus protection barrier biological agent. The preparation method comprises the following steps: preparing a biological nanometer mesoporous material; preparing a specific binding receptor or ligand; preparing protection filtering liquid: mixing and reacting solutions with certain concentrations obtained in step 1 and step 2, and performingreduced pressure distillation to obtain the protection filtering liquid; preparing a multilayer structure medium: a membrane polymer is synthesized by solvent casting, semi-solid casting, hot melt extruding (HME), solid dispersion extruding or rolling, then carrying out molding and / or evaporating part of added liquid on the membrane polymer to form the membrane, and preparing the protein virus protection barrier biological agent: soaking the membrane obtained in step 4 at normal temperature by the protection filtering liquid obtained in step 3 or spraying the protection filtering liquid obtained in step 3 on the two sides of the membrane obtained in step 4 at high pressure. By adopting the highly active and small particle size nanometer material provided by the invention and combining with special technology, not only can large particle pollutants be effectively filtered and blocked, but also small particle size toxic and harmful substance such as virus, bateria or allergen can be effectively adsorbed, thereby providing omnibearing protection for people, releasing a material with the omnibearing and efficient infectious disease prevention function in the world-wide for the first time and protecting health for people.

Description

technical field [0001] The invention belongs to the field of protection against toxic and harmful substances, and in particular relates to a protein virus protection barrier biological preparation and a preparation method thereof, a filter mask, an air filter, an air purifier and the like. Background technique [0002] With the improvement of living standards and changes in lifestyles, people spend more and more time working and living in closed environments. Hospitals, schools, theaters and other places, as well as vehicles, airplanes, high-speed rails and other vehicles, are all caused by virus transmission. The hardest hit area for cross-infection. People have always believed that the most serious air pollution is the external environment. In fact, the indoor environment of buildings such as offices, living rooms, restaurants, theaters, and dance halls has a much greater impact on people's health than outdoors. [0003] For example, indoor pollutants mainly come from th...

AI Technical Summary

Problems solved by technology

Therefore, these two methods still cannot effectively and specifically adsorb viruses and bacteria, and it is more difficult to adsorb and intercept allergen molecules with smaller particle sizes

Can not play an effective role in diseases transmitted by the respiratory tract of pathogenic microorganisms such as bacteria and viruses

[0007] In the same way, air purifiers generally use a similar principle, which can intercept large particle size substances to a certain extent, but cannot produce effective effects on viruses, bacteria, and allergen molecules.
