Description
Technical field
The present invention relates to a kind of for adsorbent of formaldehyde adsorption in indoor and automobile and preparation method thereof, it is net to belong to air
Change technical field.
Background technology
Indoor environmental quality can directly affect human health status.It is counted according to related data, the life of the nearly half in the whole world
It is living that indoor environmental pollution has caused 35.7% breathing problem in the room air for having pollution, 22% chronic lung disease and
15% tracheitis, bronchitis and lung cancer.International related organization's investigation discovery, newly-built or reconstruction the building in more than 30% whole world
, all there is the harmful substance unfavorable to people's health in the air in object, room air pollution has been put into public health
One of 5 maximum environmental factors are influenced, wherein formaldehyde is typical pollutant matter.
Formaldehyde is a kind of colourless readily soluble and the microstimulation gas with high bioactivity and potential carcinogenicity, to human body
Harm there is chronicity, latency and concealed.Formaldehyde has Study on Acute Toxic Effects to human body, is mainly shown as to eye
Thus the stimulation of eyeball, skin, mucous membrane generates ophthalmodynia, sheds tears, the symptoms such as dermatitis.Long-term inhaled concentration is 0.45mg/m3Formaldehyde
Chronic respiratory disease can be caused to increase；Suck high-concentration formaldehyde（>60mg/m3）It can lead to pneumonia, larynx and pulmonary edema, bronchus
Spasm, pant, frothy sputum even respiratory and circulatory failure it is lethal.Formaldehyde source in room air mainly includes：
（1）All kinds of urea-formaldehyde resin adhesives of the ornament materials such as skirting, ceiling, such as glued board, core-board, Midst density
Fiberboard and particieboard etc.；
（2）Containing formaldehyde components and all kinds of ornament materials outwardly distributed are possible to, such as wall paper, wallpaper, paint and painting
Material etc.；
（3）It is possible that the Interior Display and daily necessities of emitting formaldehyde, such as furniture, chemical fibre carpet and foamed plastics.
Japanese Yokohama national university research shows that, the most short acquisition time of indoor formaldehyde is 3 years, up to 15 years, usually
It is 5 to 8 years, the accumulation harmfulness influence that human body generates for a long time can not be ignored.In recent years, domestic economy development and life
The flat increasingly raising of running water improves requirement of the people to life and work Condom decoration level, but also increases dress simultaneously
Formaldehyde is to the extent of injury of health in pool material.It is estimated that people in life about 90% time be to spend indoors
, wherein 60% time spend at home.
At present, the purification techniques of formaldehyde in air pollution is most of by the use of activated carbon as adsorbent, large specific surface area,
Adsorption capacity is stronger, but since activated carbon is non-polar adsorbent, it is stronger to the adsorption capacity of apolar substance, to pole
Property substance adsorption capacity it is smaller, therefore adsorption effect unobvious of PARA FORMALDEHYDE PRILLS(91,95) can not make room air reach purification requirement.Cause
This is badly in need of developing a kind of new and effective formaldehyde adsorbent.
