Abstract
The invention discloses a nano micro-pore air purification net and a preparation method thereof. The nano micro-pore air purification net is made of a gauze element base material and a nano micro-pore membrane, wherein the nano micro-pore membrane is adhered to the gauze element base material and is made of cured colloid and nano fiber short chopped strands; the nano fiber short chopped strands are adhered to the cured colloid in a criss-cross manner, thereby forming micro-pores of which the diameters range from 0.1 micron to 2.5 microns. Therefore, when external air enters a room through the nano micro-pore air purification net, granules of which the diameters are greater than 2.5 microns can be baffled outside the room; due to adoption of nano fiber, pollen can be effectively isolated, and intense ultraviolet light can be also cut off; dew is not easy to form on the nano micro-pore membrane, and even when attached to the nano micro-pore membrane, rain cannot be blown into the room easily. As the nano fiber is subjected to special fluorine treatment in the preparation process, the nano micro-pore air purification net can be automatically cleaned when water or rain is sprayed on the nano micro-pore membrane without detachment, and dirt adhered to the nano micro-pore membrane can be easily blown off by using an air blower.
Description
Technical field:
The present invention relates to a kind of air clearing product, belong to field of Environment Protection, particularly relate to a kind of nanometer micropore screen pack that can purify air.
Background technology:
Along with the fast development of suitability for industrialized production, the development of high energy consumption resource-type makes air quality increasingly worsen, the impact of industrialization on air quality is more and more serious, and along with the raising of people's living standard, people more and more pay attention to own health, air quality directly has influence on the healthy of people, present people more and more pay attention to IAQ, due to the entire lowering of Outdoor Air Quality, especially in haze weather, indoor air quality is also very bad, air cleaning facility is brought into use in order to improve the indoor many people of air quality, this promotes udst separation technology development and raising.At present, indoor air purification is realized by air purifier, at indoor location air purifier, the air intake of indoor carries out filtering by air purifier, adsorption cleaning, some clarifiers also have disinfection function, realize the absorption to room air, filtration and sterilization thus, the pollutant in air is stayed each metafiltration on the net, obtain pure and fresh air.This air purifier not only price is high, and use cost is high, and the consumptive material such as filter screen, active adsorbing material needs timing to change, and uses inconvenience, and consumptive material costly simultaneously.
In recent years, although air purifier progressively be familiar with by people, but all adopt non-woven fabrics or INVENTIONPaper filter granule dust in air purifier, charcoal absorption noxious odor isotype, although this purification method is effective in theory, but the physical characteristic of this kind of material determines them has intrinsic defect, such as active carbon once with the water molecules in air, adsorption capacity will be lost, after paper filter core makes moist, permeability can significantly decline, therefore, existing cleaning filtration screen of air, adsorption capacity is poor, service life is short, clean-up effect is undesirable.
This be applicant carried out to long-term research and test, work out a kind of nanometer micropore air-purifying net.
Summary of the invention:
