Description
Technical field
The present invention relates to a kind of adsorbent for formaldehyde adsorption in indoor and automobile and preparation method thereof, belong to technical field of air purification.
Background technology
Indoor environmental quality directly can affect human health status.According to related data statistics, the people of the nearly half in the whole world lives in the room air of pollution, and indoor environmental pollution has caused the breathing problem of 35.7%, the chronic lung disease of 22% and the tracheitis of 15%, bronchitis and lung cancer.The investigation of international related organization finds, air in the building of the newly-built or reconstruction in the whole world more than 30%, all exist the healthy disadvantageous harmful substance of people, room air pollution has been put into one of 5 environmental factors that public health has the greatest impact, and wherein formaldehyde is typical pollutant matter.
Formaldehyde is a kind of colourless easily molten and have the microstimulation gas of high bioactivity and potential carcinogenicity, and it has chronicity, latency and concealed feature to the harm of human body.Formaldehyde has Study on Acute Toxic Effects to human body, and main manifestations is the stimulation to eyes, skin, mucous membrane, produces ophthalmodynia thus, sheds tears, the symptom such as dermatitis.Long-term inhaled concentration is 0.45mg/m
3formaldehyde chronic respiratory disease can be caused to increase; Suck high-concentration formaldehyde (>60mg/m
3) can pneumonia be caused, larynx and pulmonary edema, bronchial spasm, pant, even respiratory and circulatory failure is lethal for frothy sputum.Formaldehyde source in room air mainly comprises:
(1) all kinds of urea-formaldehyde resin adhesives of the ornament materials such as skirting, ceiling, such as glued board, core-board, medium density fibre board (MDF) and particieboard etc.;
(2) containing all kinds of ornament materials that formaldehyde components also likely outwardly distributes, as wall paper, wallpaper, paint and coating etc.;
(3) the likely Interior Display of emitting formaldehyde and daily necessities, as furniture, chemical fibre carpet and foamed plastics etc.
The research of Yokohama national university of Japan shows, the release period of indoor formaldehyde the shortest is 3 years, and the longest is 15 years, is generally 5 to 8 years, and it can not be ignored the accumulation harmfulness impact that human body produces for a long time.In recent years, the raising day by day of domestic economy development and living standard, improve the requirement of people to life and work Condom decoration level, but also to increase in art work formaldehyde to the extent of injury of health simultaneously.According to estimates, people nearly in life 90% time spend in indoor, wherein the time of 60% is spent at home.
At present, the purification techniques major part that formaldehyde in air is polluted utilizes active carbon as adsorbent, its specific area is large, adsorption capacity is stronger, but because active carbon is non-polar adsorbent, therefore comparatively strong to the adsorption capacity of apolar substance, less to the adsorption capacity of polar substances, therefore the adsorption effect of PARA FORMALDEHYDE PRILLS(91,95) is not obvious, and room air cannot be made to reach purification requirement.Therefore a kind of new and effective formaldehyde adsorbent of exploitation is badly in need of.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, provide a kind of adsorbance large, clearance is high, and low-cost formaldehyde adsorbent and preparation method.
According to technical scheme provided by the invention, a kind of adsorbent for formaldehyde adsorption in indoor and automobile, it adopts aluminium slag as carrier, and carrier sprays the mixed solution of triethylene tetramine and NaOH; This adsorbent is that white is spherical, and the composition of carrier is aluminium ground-slag and the alumina powder of mass ratio 1-2:1-3.
Described aluminium slag make a living steam wheel hub produce aluminium material oxidation thing.
Described is 3.0-5.0mm for the adsorbent diameter dimension of formaldehyde adsorption in indoor and automobile.
The described preparation method for the adsorbent of formaldehyde adsorption in indoor and automobile, step is:

(4) polishing: sugar coating machine ball cylinder put into by the material that grain size requires that meets after step (3) being sieved, make material in cylinder body with the speed uniform roll of 20-40r/min, spray surface smoothness and roundness that 5-10kg water improves spheroid, obtain semi-finished product;
(5) leave standstill: be placed in constant temperature and humidity room after being installed by semi-finished product bag special polished for step (4), control at 50-80 DEG C by its temperature, humid control, at 40%-50%, leaves standstill 40-50h;
(6) dry: drying is carried out to step (5) gained material; Baking temperature 120-150 DEG C, time about 1-3h, by moisture control at 10%-20%;
(7) preparation of mixed solution: triethylene tetramine, NaOH and water are dissolved according to mass ratio 5-15:1:15-20 and is mixed with mixed solution;
(8) spray: spherolite dried for step (6) is put into sugar coating machine, with the speed uniform rotation of 20-40r/min; Then by spherolite and mixed solution according to solid-to-liquid ratio 5:1-2, liquid is evenly sprayed on spherolite with the speed of 1-2kg/min, sprays end and be rotated further 10-20min, obtain the adsorbent of product for formaldehyde adsorption in indoor and automobile.
Beneficial effect of the present invention: adsorbent prepared by the present invention is compared with existing formaldehyde adsorbent, and formaldehyde adsorption ability is comparatively strong, and saturated extent of adsorption is large, absorption thoroughly, can not produce secondary release; Utilize adsorbent provided by the invention to carry out formaldehyde adsorption process, the rate of adsorption is fast, and thoroughly, adsorption rate is high in absorption; The raw material sources used in preparation process of the present invention is in producing the aluminium slag that produces of automotive hub, with low cost, and reaches and control harmful object with useless, serves vital effect to environmental protection.
