Problems solved by technology

[0004] The primary technical problem to be solved by the present invention is to provide a new air purification scheme with convenient operation and good effect for the problem of microbial pollution in the air of human settlements. It relies on a cationized polymer material with a skeleton structure, which is easy to Attaching small water droplets can make the air circulate quickly and realize the full intersection of water and air. The bacteria in the air can be absorbed by the cationic surface or transferred to the water droplets, so the purpose of purifying the air can be achieved.

Embodiment Construction

[0019] Below in conjunction with embodiment the present invention is described in further detail.

[0020] Material preparation: Dissolve commercial chitosan in dilute acetic acid aqueous solution (the concentration of 1-2wt.% for the viscosity greater than 400mPa; the concentration of 2-3wt.% for the viscosity in the range of 200-400mPa) and add a small amount Cationic surfactant (such as dodecyltrimethylammonium chloride, the content in the solution is 0.1 ~ 0.2wt.%), then soak the melamine sponge in the solution, take it out and suck off the excess with vacuum Solution, ensure that it does not flow out under standing, and then dry it in an oven at 60°C for 2 to 3 hours, and then soak it in a sodium carbonate solution with a pH of 9 to 10 for 20 to 30 minutes to deprotonate chitosan After forming an insoluble film to cover the surface of the skeleton, the material is washed with clear water and then soaked in a 10-15wt.% ethanol solution of ethylene glycol diglycidyl ether t...

Abstract

The present invention relates to an ionizing matrix polymer, its preparation method and its application in the removal of particulate matter pollution. Using the unique three-dimensional skeleton structure of the existing melamine sponge, the chitosan coating is coated on the skeleton, and then ethylene glycol glycidyl ether reacts with the chitosan coating to make it cross-linked and carry a large amount of foam on the surface. The epoxy group, and then use the epoxy group to react with sodium bisulfite to generate sulfonate anion, and finally use electrostatic interaction to introduce polydimethyldiallylammonium chloride to the surface of the material to form a polyelectrolyte hydration layer , so that the surface of the skeleton adsorbs a large number of small water droplets due to cationization, and when the air flows through the pores of the material, bacteria can be adsorbed to the surface of the material or transferred to small water droplets, thereby realizing the purification of air contaminated by microorganisms. The advantages of this air purification method are: the structure of the device is simple, the material can be recycled many times, the cost is low, the energy consumption is small, the adaptability is strong, it is harmless to the environment and people, and there is no secondary pollution.

Description

technical field [0001] The invention relates to a cationic skeleton polymer capable of removing bacterial pollution in the air and a preparation method thereof. Using the cationic skeleton polymer can conveniently, quickly and effectively remove microbial pollution in the air. Background technique [0002] The air is not a good living place for microorganisms, because not only does the air not have the nutrients and sufficient water needed for the growth and reproduction of microorganisms, but also the ultraviolet radiation in the sun. However, soil, water bodies, various rotting organic matter, and microorganisms on human and animal bodies can all be carried into the air with the movement of the airflow. There are indeed many invisible microorganisms floating in the air, and they mainly include various cocci, Bacillus, pigment-producing bacteria, and fungal spores that are resistant to drying and radiation, etc., and there may also be pathogenic bacteria such as Mycobacter...
