Description
Technical field
The utility model belongs to air filtering material technical field, particularly relates to a kind of purification of air filter material.
Background technology
China's atmosphere pollution develops into regionality, compound atmosphere pollution from coal-smoke pollution in last century, become the area that global Aerosol Pollution is the most serious, be wherein global pollution with Jing-jin-ji region, the Yangtze River Delta, Chengdu-Chongqing, central plain area etc., the average annual concentration of PM2.5 is more than 70ug/m3, exceed more than 2 times of national standard, higher than more than 7 times of WHO standard.
In addition on the one hand, indoor pollution has become the important threat to the life of people's house and health, and Environment Protect in China association relevant data statistics shows: once carried out luxurious finishing in 90% leukemia children man, annual 2100000 children die from luxurious finishing; The house decoration formaldehyde of 80%; 70% pregnant woman's miscarriage is relevant with environmental pollution; The death toll that annual China causes because of indoor environmental pollution is up to 11.1 ten thousand people, and average every day 304, people was dead.Indoor environmental pollution has become one of killer having a strong impact on modern humans's health.
Chinese Patent Application No. is 201310207844.9, publication number a kind of purification of air filter material disclosed in the patent of invention of CN103316543A, adopt PET or PPS base cloth, spin or mix and spread PET or PVA fibrage, again with PPS fibrage or with aramid fiber blending after the perverse compound of pin, finally at PPS fibrage or with aramid fiber blending PTFE microporous barrier or be covered with foaming layer.PET or PVA fibrage is layers of nanofibers, and the amount of applying is 20-50 gram/m.Adopt the PM2.5 filterability of this filter material should more than 99%, 0.3 Mm filter rate should more than 92%.But because PET or the PPS base cloth forming this filter medium structure is softer, its structure is easily caved in and is made under differential pressure, and its filtration resistance is increased exponentially, and therefore the filter material of this structure in use, the filterability of PM2.5 and 0.3 micron particles can reduce greatly, the lost of life.
Utility model content
The purpose of this utility model is just to provide the purification of air filter material that a kind of filtering accuracy and filter efficiency and life-span all can effectively improve.
In order to realize the utility model object, the technical scheme adopted is:
A kind of purification of air filter material, is characterized in that; Comprise by specification be the passive basic unit of 60-70 grams/m, to form specification be the intermediate layer of 40-50 grams/m and specification is that the superficial layer of 20-25 grams/m is formed; Above-mentioned three layers are bonded together by adhesive phase.
Form in above-mentioned purification of air filter material,
---the diameter of described glass fibre is arranged on 3-5 μm;
---the thickness of described adhesive phase is between 10-15 μm;
---on the side of described superficial layer and basic unit, dip-coating has resin bed.
Purification of air filter material provided by the utility model compared with prior art, has the following advantages:
---because this purification of air filter material is by the string and the polyester fiber mixed layer that form filter material basic unit, the glass layer in intermediate layer and the layer of polyester fiber filter material of superficial layer are formed respectively by the resin bonded laminate that cohesive force is strong, make the basic unit forming this filter material, intermediate layer and superficial layer three layers of fibrage effectively play respective effect respectively---and the basic unit formed by string and polyester fiber has enough deflections and bursting strength, and this basic unit is grown by fiber and wide, intensity is better, the pine that cellulosic degree of polymerization is higher, fiber crops, the processbearing astrocyte such as cotton linter and the better polyester fiber of intensity, therefore this basic unit has the many micropores of short texture and the higher feature of air permeability, there is huge dust capaciting ability, be the intermediate layer that 3-6 μm of ultra-fine fibre glasses are formed by diameter, effectively elimination can not only remove the particle in air, improve the filtering accuracy of filter material, more importantly its porosity formed is high, has the service life that huge dust containing capacity ensure that filter material, be the fibroplastic superficial layer of Polymer Synthesizing by diameter, there is the intermediate layer protection that higher-strength is formed ultra-fine fibre glass,
---due to be provided with between three-decker thickness be 10-15 μm between adhesive phase, the thickness of this adhesive layer not only just in time matches with the granularity of dust, can't have an impact stored at fibrage to dust, but also serve three layers of fibrolaminar adhesive effect;
---on the side of superficial layer and basic unit dip-coating have resin bed more to improve the deflection of this filter material and the life-span longer.
Accompanying drawing explanation
The structural representation of a kind of purification of air filter material that Fig. 1 provides for the utility model.
Detailed description of the invention
Be described in further details below in conjunction with the structure of accompanying drawing to a kind of purification of air filter material that the utility model provides.
As shown in Figure 1, the structural representation of a kind of purification of air filter material provided for the utility model.Namely the basic structure of this filter material comprise by specification be the passive string of 60-70 grams/m to mix with polyester fiber form basic unit 1, to form specification be the intermediate layer 2 that formed of glass fibre that the diameter of 40-50 grams/m is arranged on 3-5 μm and specification is that the superficial layer 3 that the polyester fiber (also i.e. polyster fibre) of 20-25 grams/m is formed is formed; Above-mentioned three layers are bonded together by adhesive phase 4.
In the structure forming above-mentioned purification of air filter material, the string and the polyester fiber that form basic unit generally adopt fiber length and the fibers such as the pine wide, intensity better, cellulosic degree of polymerization is higher, fiber crops, cotton linter and the better polyester fiber of intensity, the many micropores of short texture of basic unit and air permeability high, have the advantages that the low and dust containing capacity of filtration resistance is high; The ultra-fine fibre glass intermediate layer that diameter is 3-5 μm has high filtering accuracy and dust containing capacity.
In the formation basic unit 1 of this filter material and two sides of superficial layer 3, the resin of dip-coating is phenolic resins, acrylic resin is or/and polyvinyl acetate, can be infiltrated in when these resin adhesive liquid are applied inside hang over fiber is formed superficial layer and basic unit side on the resin bed of dip-coating, drying operation, the surface of filter material and certain depth layer is made to have more very holder effect, and effectively can improve physical strength and the structural strength thereof of filter material, the instructions for use of filter material can be met, when for filtering, good strainability can be kept, its structure is not caved under differential pressure, and maintain the pre-existent pore of filter material, the fiber of filter material in filter process and other tissue is prevented to be moved phenomenon.In addition, dipping also can make filter material have higher chemical resistance and solvent resistant performance.
The above-mentioned basic unit 1 of same formation, its adhesive of adhesive phase 4 between intermediate layer 2 and superficial layer 3 can hang on the fiber of the basic unit of both sides and intermediate layer 2, intermediate layer and superficial layer, form the pure adhesive layer of little 10-15 μm of its thickness, the bondline thickness of 10-15 μm comprises adhesive and hangs over the thickness that both sides fiber is formed.Therefore make between can not the having an impact to the filtration of dust in filter material of pure adhesive layer.
