Abstract
The invention discloses the preparation methods and application of a kind of web with catalyzing oxidizing degrading formaldehyde; using sol-gal process or dip-coating method; inorganic oxide film is covered on hydrophilic fibre surface; fiber is protected; and porous inorganic oxide thin layer is constructed on its surface; modified fiber immerses in the solution of catalyst precursor; after being sufficiently impregnated; precipitating reagent or reducing agent is added; in fiber surface in-situ preparation nano-catalyst particles; again through drying, the fiber is woven and superposition is to get web.The present invention is the web of the purification air based on hydrophilic fibre preparation, it can the volatile organic matters such as mild catalytic degradation of formaldehyde, porosity is very flourishing, load has the nanocatalyst of the efficiently volatile organic matters such as removal degradation of formaldehyde on tiny fiber, good air purification effect, it is mountable in air purifier and fresh air system.
Description
Technical field
The present invention relates to technical field of air purification, in particular to the preparation method of the web with catalyzing oxidizing degrading formaldehyde
And its application.
Background technique
The interior decoration of modern architecture and modern furniture often bring the volatile organic matters such as formaldehyde to pollute, and it has been established that
The volatile organic matters such as formaldehyde severely impact the health of people, even result in cancer.In order to purify air, improve
Air quality, powerful social demand promote the fast development of air purifier or fresh air system, air purifier and fresh air
System becomes the important configuration of the modern life.Air purifier or fresh air system at runtime, commonly use airstrainer to remove
Pollutant in air, main resistance when filter screen is air flowing.For removing the volatile organic matters such as formaldehyde in air
Filter screen often assembled by catalyst granules, the gap between particle constitutes the channel of air flowing, and this gap is difficult
With modulation, and as the increase of catalyst amount, the compactness of catalyst grid increase, porosity is reduced, the resistance of air flowing
Power increases.In the exhaust gas purification system of motor vehicle, commonly uses ceramic honey comb block and carry out supported catalyst.Ceramic honey comb block possesses abundant
Regular duct, but its specific surface area is still smaller, so being still to be modified its surface in supported catalyst, improves
Its specific surface area improves the microcellular structure on surface, so supported catalyst is equally a complicated work on ceramic honey comb block
Make, moreover ceramic honey comb block is usually sintered at high temperature, manufacturing cost is high, it is difficult at room temperature in terms of air cleaning
It promotes and applies.Also the filter screen that useful glass fibre and catalyst granules assemble on the market, but it removes the volatility such as formaldehyde and has
The performance of machine object is poor.
The porosity of cleaning filtration screen of air is the important parameter for influencing air purifier, and filter screen too secret meeting leads to air
By when resistance it is too big, filter screen too it is dilute will lead to air residence time deficiency, the performance for removing air pollutants is too poor, institute
It is critically important parameter with suitable porosity.Common air cleaning filter screen is assembled by catalyst granules, filtering
The porosity of net is mainly made of the gap between catalyst granules, and porosity is difficult to modulation.
Summary of the invention
It is an object of the present invention to be directed to the above-mentioned deficiency of the prior art, provide a kind of with catalyzing oxidizing degrading formaldehyde
Web preparation method and application, based on hydrophilic fibre preparation purification air filter screen, the filter screen porosity is very
