Abstract
The invention discloses a filter material capable of purifying indoor air and eliminating second-hand smoke. A slurry is synthesized from natural mineral sepiolite, attapulgite, tourmaline, rare-earth mineral, nanometer silica, a non-toxic adhesive and the like; and then the slurry is uniformly adhered in a PET (polyethylene terephthalate) fiber layer, and dried, shaped and folded to prepare the filter material with an unequal thickness of 15-60mm. Toxic and harmful materials and harmful sol materials obtained in indoor air after tobacco is combusted can be absorbed, filtered and catalyzed by the filter material provided by the invention. The filter material can release far infrared rays so as to excite the natural mineral tourmaline to permanently and stably release negative ions, wherein the concentration (more than 6000/cm<3>) of the negative ions greatly exceeds the standard (1000-1500/cm<3>) of indoor fresh air, confirmed by world health organization, therefore, the effects of sterilizing, removing toxicity and peculiar smell, eliminating the second-hand smoke, outputting clean air and thoroughly improving the indoor air pollution state are achieved.
Description
Technical field
The present invention relates to filtering material and manufacturing approach thereof, specially refer to a kind of filtering material and manufacturing approach thereof that can purify the air of a room and eliminate second-hand-cigarette.
Background technology
World Health Organization's investigation shows that polluted room air has seriously threatened human health, and human 68% disease is relevant with polluted room air.
Environmental protection tests mechanism introduction according to domestic authority: as long as indoor airborne everywhere negative ion concentration remains on 3000/cm for a long time equably
3More than, can solve the room air pollution problem of serious threat human health.
For a long time, second-hand-cigarette is damaging the healthy of surrounding population always, comprises family member, good friend's health.The comprehensive regulation to second-hand-cigarette is difficult to carry out always and promotes, and its one of the main reasons is to lack the suitable filtering material that can eliminate second-hand-cigarette and purify the air of a room.
The nonmetallic mineral sepiolite, rich magnesium, fibrous, loose structure, specific area is big, and polar molecule is had stronger chemo-selective, and absorption property is splendid, in air purification field, is used widely.Solation compound in the absorption of sepiolite powder ability, filtration, the catalysis flue gas is stronger to the colloidal sol chemical combination particle adsorption capacity below the 0.1um especially.But the smoke filtration catalysis material that sepiolite is processed can not be self-cleaning; Adsorbed colloid and colloidal sol chemical combination particle stick to the surface of the filter medium after the catalysis; Influenced proceeding of adsorption process, reduced whole adsorption capacity, adsorption efficiency is also along with decline.
Summary of the invention
The technical problem that the present invention will solve is to overcome deficiency of the prior art, and a kind of filtering material that can purify the air of a room and eliminate second-hand-cigarette is provided.In order to eliminate the pollutant in second-hand-cigarette and the room air, solve the second-hand-cigarette of present domestic urgent need solution and the serious problems of room air pollution.
The present invention realizes through following technical measures.A kind of filtering material that can purify the air of a room and eliminate second-hand-cigarette comprises: base cloth, and 6～7 parts in the nonmetallic ore adsorbent of meter by weight, 1.5～1.25 parts of negative ion powders, 1.5～1.25 parts of far-infrared powders, 1～0.5 part of nano silicon.
As material, arrange, weight: 105-110g/m by porous with the PET fiber for described base cloth
2, effective drainage porosity is more than or equal to 80%, average pore size 0.5-0.8mm.
Said nonmetallic ore adsorbent comprises: 4～4.5 parts of Ji sepiolite breezes, 2～2.5 parts of attapulgite breezes by weight.
Said negative ion powder is a tourmaline powder.
Said far-infrared powder is the synthesizing rare-earth mineral powder that contains germanium, selenium, cerium, strontium, ytterbium various element.
A kind of manufacturing approach that can purify the air of a room and eliminate the filtering material of second-hand-cigarette comprises the steps:
1, by described proportion scale, adds diluent (water), put into mixer, mix stirring, stir into mud.
2, after the above-mentioned 5 kinds of raw meal of affirmation have been mixed into muddy; Add emulsion binding agent; Mix stirring; Be stirred to slurry and become the foamed starchiness of milky; If solid content is too high; Add diluent (water), adjustment solid content 50-55% continues to be stirred to slurry and becomes the foamed paste of milky;
3, the foamed paste of milky is put into painted groove, adopt the strength mixer, guarantee that the slurry solid, liquid is not evenly, precipitate;
4, base cloth is immersed in the painted groove, make base cloth all be impregnated into slurry, the back gets into extruding drum, under the pressure of setting (0.5-0.65MPa), extrudes unnecessary slurry, and after confirming evenly to contain slurry in the base cloth hole, base cloth gets in the baking oven and bakes drying.
5, the rolling behind levelling process of dried base cloth is for use.Filter medium thickness on the base cloth is even at this moment, forms a kind of filtering material that can purify the air of a room and eliminate second-hand-cigarette.
At this with 1～5 precedence of representing these steps.
Described emulsion binding agent is the vinyl acetate of solid content 60% a---ethylene copolymerization emulsions.
Natural mineral tourmaline is the mineral that unique in the world a kind of natural energy sends anion.Because natural mineral tourmaline negative ions generated in the normal state of less, but after extensive testing we confirmed: tourmaline in the far infrared waves driven by a large number of negative ions to produce, so the use of far infrared powder combined with Tourmaline, then add natural minerals sepiolite powder, attapulgite powder, nano silica, which is immersed in the slurry synthetic fabric, and then extruding, drying, leveling processed into filter material.Far-infrared powder in the filtering material sends far infrared wave; Tourmaline powder produces a large amount of anions (permanent long-term release anion) under the driving of far infrared wave; Drive the sepiolite breeze simultaneously; Magnesium in the attapulgite breeze, manganese; Self-excitation catalysis such as the boron in the tourmaline powder are adsorbed on the solation compound of pollutants such as flue gas on the filtering material, virus, bacterium; Reach efficient, macro-energy, nonvolatil operational effect, eliminate peculiar smell, kill bacteria thus, eliminate second-hand-cigarette.Filter medium surface dust containing capacity can reach 200-300g/m
2, rising to certain limit with resistance, filtering material can also be taken out, with reusing after flushing with clean water, the drying.
Raw material of the present invention, auxiliary agent etc. all can be buied on market, and all meet national industry or company standard.
After the present invention adopts abovementioned technology; The filtering material that can purify the air of a room and eliminate second-hand-cigarette of the present invention that above-mentioned natural minerals synthetic slurry shapes; Can be with the various viruses that are stained with in the room air; Bacterium; The micronic dust particle of flue gas is adsorbed on the surface; Kill; Catalysis; Remove peculiar smell; And Promethean employing far infrared drives; Excite the anion in the natural minerals efficient; Macro-energy; Nonvolatil release, the filtering material that can purify the air of a room and eliminate second-hand-cigarette of the present invention are a kind of novel indoor air filtering materials with revolutionary variation.
