Ionized skeleton polymer capable of clearing particulate pollution and preparation method of ionized skeleton polymer

Abstract

The invention relates to an ionized skeleton polymer and a preparation method thereof as well as application of the ionized skeleton polymer in clearing particulate pollution. According to the invention, the existing three-dimensional skeleton structure specific to melamine sponge is utilized so that a chitosan coating coats the skeleton, glycol glycidyl ether and the chitosan coating react to be crosslinked, the surface of the skeleton carries abundant epoxy groups, the epoxy groups react with sodium hydrogen sulfite to generate sulfonate negative ions so that the surface of the skeleton adsorbs a plenty of small water drops due to strong hydrophilization, and particulates can be transferred to the adsorbed water drops when air circulates in a material duct so as to achieve the purification of polluted air. The air purification manner has the advantages that device structure is simple, and the ionized skeleton polymer can be recycled many times, is low in cost, little in energy consumption and strong in adaptability, has no harm to environment and human and has no secondary pollution.

Description

technical field [0001] The present invention relates to the preparation of a novel ionizing framework polymer and its use in the removal of particulate matter pollution. The use of the ionizing backbone polymer can provide a method for removing particulate matter in the air that is convenient, fast and highly effective. Background technique [0002] Particulate matter with a diameter of less than 2.5 microns is called PM2.5. In recent years, with the intensification of pollution caused by automobile exhaust, industrial combustion, household or nature, the concentration of PM2.5 in the air has risen rapidly, and the harm to human health has become more and more serious. It's getting serious. Air pollution is responsible for nearly 2.1 million premature deaths worldwide each year, according to a new study. A large number of studies have found that the level of PM2.5 is positively correlated with the incidence and mortality of lung cancer. PM2.5 can enter the blood, and what ...

Problems solved by technology

There are two disadvantages in this filtering technology: one is that there is a contradiction between the filtering effect and the air flow rate, that is, in order to improve the filtering effect, the thickness of the filter layer is often increased, then the air circulation resistance increases, and the air flow rate becomes smaller. To increase the air flow under the premise of ensuring the filtering effect, the power of the fan has to be increased, which not only wastes energy, but also increases the noise

[0004] The existing air purification technology has shortcomings, fundamentally speaking, it lacks one of the most basic elements---water
