Abstract
An air cleaning material is prepared from natural shell through biologic classifying, ultrasonic washing, removing odor, acid treating, drying, and microwave or far infrared activating. It can remove H2S, SO2, formaldehyde, etc from air.
Description
Technical field
The present invention relates to a kind of material for air purification, relate to a kind of functional material that can purify air that obtains by shell specifically, also relate to this preparation methods in addition.
Background technology
Be accompanied by industry and rapid development of economy, environmental pollution becomes the human common social concern of paying close attention to, and it then is wherein comparatively serious part that local environment is polluted.Local environment is meant the less space of human participation activity therein and relative closure, mainly comprises family room, office, toilet, inner chamber of car etc., and the modern nearly has that 80% time is to spend in indoor local environment.The various novel construction materials and the H of finishing generation
2S, SO
2Cause the generally pollution of indoor local environment with toxic gases such as formaldehyde.
At the with serious pollution problem of present local environment, scientists has been carried out a large amount of research in theory.The patented technology of air cleaning aspect mainly concentrates on two aspects at present: the one, utilize different carriers, and attached with novel light-sensitive material and sterilization material, under the irradiation of visible light, ultraviolet light, reach the purpose that purifies air; Another kind is to utilize such as adsorbents such as active carbons, is equipped with multiple medicinal herb components, the pernicious gas in the absorbed air etc.And it is just less relatively both at home and abroad about the research of the air-cleaning function of shell.Shortcomings such as these patented technology ubiquity feasibilities are poor, cost an arm and a leg, install trouble, function singleness, the term of validity are short.Therefore develop economical and practical, effect is obvious, holding concurrently to become a kind of needs as the novel air purified product that ornament is beautified the environment.
Summary of the invention
The objective of the invention is to develop a kind of abundant raw material, economical and practical, easy to use, clean-up effect is obvious, and the material for air purification of holding concurrently and can beautify the environment as ornament.Another purpose is to develop the preparation method of this material for air purification.
The present invention is raw material with the natural seashell, removes technologies such as raw meat, acid treatment, drying, non-thermal effect activation and has made the material with the effect of purifying air through biology classification, ultrasonic wave cleaning, deodorizing, and this material is to H
2S, SO
2And CH
2Three kinds of gases of O all have air purification effect preferably, adopt modern processing this material can also be made shellwork, ornament, commodity etc. in addition, thereby have realized purpose of the present invention.
Material for air purification of the present invention is characterized in that being prepared by the method that may further comprise the steps:
(1) natural seashell is picked by the classification of shellfish biology characteristic of division;
(2) ultrasonic wave cleans shell;
(3) in 60～100 ℃ water-bath, handle shell, remove stench flavor;
(4) soak shell in turn with citric acid solution and acetum, wash to there not being tart flavour with running water then;
(5) with the shell drying;
(6) the employing frequency is that microwave or the wave-length coverage of 915MHz or 2450MHz are the far infrared of 50～500 μ m, and temperature remains between 60～90 ℃, and the activation processing shell obtains product.
The described natural seashell of step (1) can be a scallop, oyster, paphia undulata, nautilus, in the beautiful spiral shell etc. one or more, the described ultrasonic wave of step (2) cleans and can adopt commercially available ultrasonic cleaner, being preferably in frequency is to clean in 40～80KHz ultrasonic cleaner, time is 0.5～1.5h, to remove the dust of shell surface, impurity, harmful substances such as parasitic animal and plant, the described processing time of step (3) is 10～30 minutes, to remove the stench flavor of shell, preferably also in boiling liquid, add Radix Glycyrrhizae, the mass fraction of the described citric acid solution of step (4) is 5%～10%, the mass fraction of acetum is 1%～5%, each soaks 2～4 times, each 1～3h, to enlarge the loose structure of shell itself, the described drying of step (5) can adopt conventional method, for example shellfish material is dried naturally, or to adopt temperature be 80～100 ℃ of oven drying 2～4h, or to adopt temperature be 60～80 ℃, and vacuum is 2.66 * 10
4Pa～5.32 * 10
4Pa vacuum drying 4～7h, the described microwave activation processing time of step (6) is 10～30s, the described far infrared activation processing time is 1～3h.
The preparation method of material for air purification of the present invention as mentioned above.
Because the special growing environment of ocean shell, make and itself just have special structure, result according to electron microscopic observation, mainly comprise special constructions such as alveolate texture, column structure, shell shape structure, lamellar structure, vein texture, through a series of chemistry and physically activated processing, make the structure and the molecular grating of shell own that variation take place, increased its surface area and porosity greatly, strengthen its physics and chemistry absorption property, thereby made material of the present invention have H in the absorbed air
2S, SO
2Effect with pernicious gases such as formaldehyde.The experiment proved that the average purifying rate to pernicious gas behind the material for air purification 4h of the present invention just can reach 40%, the average purification efficiency behind the 10h reaches more than 60%, illustrates that this material can be effective as air purifying preparation and use.Because shell has the color of riot of color, various striped, grotesque profile, firmly get liking of people in addition.Material for air purification of the present invention is made into handicraft, family adornment, tourist souvenir of various beauties etc., has more increased its glamour.
Advantage of the present invention is:
(1) raw material sources of the present invention need not add any man-made additive in the Nature in process, and to greatest extent development and utilization the shell resource;
(2) operation is simple for preparation method of the present invention, has very strong actual operability, utilizes the adsorption activity of non-thermal effect active materials such as microwave, far infrared, improved the performance of product when saving the energy again greatly, belongs to green process technology;
(3) the resulting product of the present invention is when beautifying the environment, has higher purification efficiency again, and itself just have anti-go mouldy, antibiotic effect, can be processed into difformities and different size dimensions such as square, rectangle, polygon by modern technologies, and make commodity (as cushion, back cushion, light fixture etc.), ornament, handicraft, place local environments such as office, family, inner chamber of car, public place of entertainment, reach multi-efficiencies such as beautifying the environment, provide amenities for the people, ensure health.
