Manufacturing method of multi-functional composite chemical filter materials for harmful gas deodorization and multi-functional composite chemical filter therefrom

摘要

The composite chemical filter according to the present invention comprises the steps of: a) preparing a spinning liquid by mixing and dispersing a base resin, an active particle, a particulate collecting agent, a master batch and a solvent, which are made of a synthetic resin or a biodegradable resin; b) spinning the spinning solution to produce fibers; And c) fabricating the nonwoven from the prepared fibers. Depending on the kind of the base resin according to the present invention, the composite chemical filter includes active particles such as elvan stone and ion exchange resin powder alone or two or more to improve the function of removing harmful gases, There is no worry, and the manufacturing process is very simple due to the fiber spinning method, which can greatly reduce the cost reduction burden. In addition, when biodegradable resins are used, they effectively adsorb gaseous substances such as hydrogen sulfide, mercaptans, amines, and phosphorus, thereby improving the deodorizing effect. Especially, when a tobacco filter is used, it decomposes naturally even after disposal including biodegradable polymers. The burden on the user can be reduced. In addition, the spinning solution further includes a particulate capture agent so that the noxious metal contained in the noxious gas is adsorbed to the surface of the filter at a high concentration so that the noxious metal can be effectively adsorbed at low cost. Based on these characteristics, the composite chemical filter and the biodegradable composite chemical filter according to the present invention can be effectively used not only in air conditioners for semiconductor clean rooms, automobiles, industrial facilities, but also for household cleaners, air conditioners and tobacco filters.
