Description
Technical field
The present invention relates to a kind of filter paper, more particularly to a kind of composite air filtering paper belongs to air filtration technical field.
Background technology
With the high speed development of modernization industry, environmental pollution is seriously threaten life and the health of the mankind, and the injury of recent air pollution on human is particularly evident, and extensive haze weather is attacked repeatedly.Continuous improvement of the country to quality of air environment attention degree, PM 2.5 is included new Air Quality Evaluation system.How to reduce pernicious gas in air using efficient filtering material and enter human body or extremely urgent to the pernicious gas progress effectively filtering of discharge.In order to be able to realize the purpose of air cleaning, the filtering material of novel high-quality progressively turns into the study hotspot of researcher.Glass fibre have dimensional stability compared with it is strong, be unlikely to deform, electrical insulating property is good, anti-medicine is good, and with the good characteristic such as acid and alkali-resistance, oil resistant, corrosion-resistant, heat-resist, heat conductivity be small.Thus, all-glass paper has high filter efficiency, good chemical stability and relatively low resistance, the preferred material as efficient and ultra high efficiency air cleaner, it is adaptable to the application of the air cleaning of every field.But, there is also some shortcomings for glass fibre：Fiber Aspect Ratio is big, and surface carries electric charge, easily mutually winds and is difficult to separate；Surface smoother, can not produce wire-dividing broom purification through mashing processing, physical bond is there's almost no between fiber and fiber, the group of hydrogen bond is not formed, page can not produce bond strength naturally yet.Thus there is the defect that physical strength is relatively low, fragility is big in all-glass paper, and during machinery pressure folding, page cracky, glass fibre is often split away off.Therefore, on the basis of ensureing that the good air flow resistance of glass fibre air filter paper crosses rate odds for effectiveness, it is to improve product specification that enhancing processing is carried out to glass filter paper, develops the key problem in technology of glass filter paper kind, is also trend of the filter industry to filtering material requirement.
The U of Publication No. CN 202969162 Chinese patent devises a kind of combined filtration paper; send elsewhere and bright disclose a kind of combined filtration paper; including filter layer; in the one side or two-sided multiple with protective layer of filter layer; filter layer uses the high efficiency filter paper that glass fibre is made; protective layer is using natural or synthetic fibers, and protective layer and filter layer are an entirety by high-temperature laminating.The invention solves the caducous problem of ultra-fine fibre glass, and enhances the mechanical strength of filter paper, makes the application of filter paper wider.But send elsewhere bright simply in the compound layer protective layer of filter layer single or double; the problem of only address only ultra-fine fibre glass " hair loss "; do not improve for filter paper various aspects of performance; design is excessively dull; and it is integrally to be formed by high-temperature laminating; complex process, caking ability is not high, low intensity poor toughness.
The A of Publication No. CN 104532683 Chinese patent devises a kind of antibacterial and mouldproof glass fibre composite air filtering paper, including upper glass fibre and lower glass layer, antibiotic layer is provided between the two, the upper strata glass layer upper surface is compounded with glue spraying layer, and the lowermost fibre layer lower surface is compounded with rubber shoe latex layer；The upper glass fibre and lower glass layer are made up of a diameter of 0.35~6.5 μm of glass fibre cotton.The glass fibre air filter paper of the invention uses multi-layer compound structure, and its antibacterial moisture protection was enhanced while filter efficiency is not influenceed.But the invention only increases the antibacterial moisture protection of filter paper, and filter efficiency is not lifted but, while also not solving the caducous problem of glass fibre, mechanical strength is low, poor toughness.
The content of the invention
The purpose of the present invention is intended to overcome the deficiencies in the prior art, a kind of composite air filtering paper is provided, by in the filter layer both sides made from silk that are chopped as ultra-fine fibre glass and alkali-free glass fibre each compound one layer of adsorption layer and protective layer, bonded together with phenolic resin adhesive and filter paper is made, the adsorption layer is located in the middle of filter layer and protective layer, material used in protective layer is chemical fibre or glass, the problem of ultra-fine fibre glass easily comes off is effectively prevent while filter efficiency is not influenceed, material used in adsorption layer is the mixture of active carbon nanoparticles and nano titanium oxide, wherein activated carbon is used as a kind of porous material, effect with good absorption magazine, and the nano titanium oxide mixed can be by the formaldehyde in air, benzene type organic resolves into water and carbon dioxide, again both mixtures are evenly applied on grid cloth constitute adsorption layer, effectively improve the efficiency and dust containing capacity of filter paper, filter layer uses ultra-fine fibre glass and the chopped silk of alkali-free glass fibre, both are entangled to each other, effectively improve the intensity of filter paper.
