Description
Technical field
The present invention relates to a kind of sorbing material of efficient adsorption indoor formaldehyde toluene gas.
Background technology
Room air pollution phenomenon is extensively present in the various closed buildings such as room at present, and severe room air brings serious harm to the health of the mankind.The world environments conference held in Washington for 1997 is pointed out: room air pollution is more serious than outdoor air pollution.Air pollution problem inside rooms all receives great attention in world many countries, and Europe, North America and Japan and other countries have carried out the research work of indoor environmental quality from the 80's of 20th century.
China is the country of a cancer high incidence, a cancer patient almost within five minutes, is just had to occur, according to a large amount of research reports, the toxic and harmful that interior decoration, furniture, electrical equipment produce is the main cause that present most of cancer is brought out, modern almost 80 ~ 90% time spend in indoor, the quality of room air concerns the health of people, but the involuntary health destroying us of toxic and harmful.
Indoor toxic and harmful comprises:
Aldehydes (formaldehyde is main): as protoplasmic poison material, energy and protein bound, affect health from metabolic aspect.Low concentration formaldehyde can cause breathing disease of digestive system, and the formaldehyde of high concentration then has strong carcinogenesis.Soluble in water and the organic solvent of formaldehyde, easily adheres to, and temperature raises easily volatilization.It is one of extended residual toxic gas that slowly volatilization is carcinogenic on furniture and house ornamentation;
Benzene and Toluene class: Benzene and Toluene is the arch-criminal of leucocyte pathology, can cause chromosome pathology, and Benzene and Toluene belongs to aromatic compound, and phenyl ring is stable especially, not easily decomposes in vivo, can have a strong impact on healthy.Benzene ring substance is mainly from the paint etc. of indoor use;
Radioactive radon gas: radioactive radon gas comes from construction material or building lot, that understands continuation distributes radgas, and radgas excessive concentration can cause cell carcinogenesis and gene mutation, affects especially serious on pregnant woman, infant;
Ammonia nitriding compound: indoor ammonia nitriding compound is mainly ammonia, and ammonia can damage respiratory system and Mucosal system, and the ammonia of indoor is mainly produced by construction material.
Domestic and international great majority are all confined on the material such as formaldehyde and toluene about the research that indoor gas adsorbs, and the absorption research for radon gas or ammonia nitriding compound is relatively less, and patent is also also few.Adopt in patent CN201210408096.6 be also zeolite but its modification adopt be the process of fluorine silicon, this method for benzene, toluene class species adsorbs ability strengthen, but for the absorption property such as formaldehyde, radioactive radon gas improve and not obvious.Give a kind of metal-organic framework materials adsorption of indoor polluted air in patent CN201110023219.X, for benzene, toluene, formaldehyde etc., there is reasonable absorption property, but its synthesis is complicated, and expensive, the not general adaptability of tool.Method in patent CN200910017520.2 plays the absorption property of adsorption of indoor polluted air after being mixed by a certain percentage by several adsorbent with absorption different material, is not a kind of novel sorbing material.
The present invention comparatively speaking, ZSM-5, the price of silica gel or X molecular sieve is all less expensive, and there is high specific area and multi-pore channel structure, the features such as intensity is high, wear-resistant, corrosion-resistant, the modification of metal oxide makes it not only have adsorption capacity for indoor polluted gas in addition again, also has decomposition and prevents desorption performance.Common absorption for formaldehyde, benzene, toluene, radon gas, ammonia nitriding compound etc. is also a large feature of this material.
