Abstract
The invention discloses a filter material for an indoor air purifier. The filter material for the indoor air purifier is prepared through the steps of mixing 5-10 parts of graphene oxide, 5-10 parts of chitosan, 1-5 parts of wool keratin, 1-5 parts of calcium alginate, 1-5 parts of a crosslinking agent and 60-80 parts of deionized water, performing ultrasonic treatment, freeze-drying, grinding, and screening with a 1000-2000-mesh sieve. The filter material for the indoor air purifier uses reproducible, cheap and easily-obtained raw materials; the prepared filter material has a three-dimensional porous structure and is good in mechanical strength, reproducible, easily-degradable, green, environment-friendly, and highly-efficient in adsorption.
Description
Technical field
The present invention relates to a kind of indoor air cleaner filtrate, belong to air purification field.
Background technology
Along with the fast development of China's economy, society, the continuous growth of the size of population, the quickening of industrialization and urbanization advances, and air pollution aggravates gradually, and the particle particularly existing in air has brought serious infringement to people's health.In the U.S., the death toll causing due to Particulate Pollution is every year about 22,000-52,000 people (2000 annual data), in this numeral of Europe up to 200,000.The researchers such as the Chen Zhu academician of the Chinese Academy of Sciences publish an article on < < lancet > > magazine, estimate that China causes because of outdoor air pollution every year morning dead person's number between 350,000-500,000 people.
People's nearly more than 80% time in all one's life is spent indoor, so the quality of IAQ directly has influence on the healthy of people.Day by day serious along with outdoor air pollution, adds that the pollution of many interior decorations and ornament materials and a large amount of chemical article enter family daily life, makes that room air is same constantly to be worsened.And being widely used of air-conditioning makes indoor living space more and more be tending towards sealing, cause the self-detergent power of room air worse and worse.People have breathed stale room air, likely cause various respiratory tract disease.
Along with enhancing and the growth in the living standard of health of people consciousness, recognize all the more the importance of clean air to health.Therefore, air purifier enters into family and various office space just gradually.In European and American developed countries, air clearing product is generally for household, office life area.Survey data demonstration, air purifier reaches 27% in the popularity rate of the U.S., Japan 17%, Europe 42%, Korea S 70%, and China is less than 1%.
At present, the purification techniques that air purifier generally adopts both at home and abroad mainly contains: the methods such as UV purification, photocatalyst purification, plasma for purification, filtration, purification, electrostatic precipitation, adsorption cleaning, anion fine-purification, ozone purification, molecular complex.In these air purifying process, using absorption principle to purify air is a time-honored technology.Active carbon is the most frequently used adsorbent, and indoor multiple pernicious gas is had to certain suction-operated, but it exists, adsorbance is little, the easy shortcoming such as saturated, easy desorb, and limited to indoor major pollutants formaldehyde absorbing effect.
Summary of the invention
The present invention is directed to above-mentioned deficiency, a kind of indoor air cleaner filtrate is provided.
The present invention is achieved by following technical proposals: the deionized water of the crosslinking agent of the calcium alginate of the wool keratin of the shitosan of the graphene oxide of 5-10 part, 5-10 part, 1-5 part, 1-5 part, 1-5 part, 60-80 part is mixed, through ultrasonic processing, after freeze drying, grind and cross 1000-2000 mesh sieve and be prepared from.Wherein graphene oxide is made through ultrasonic delamination by graphite oxide, is mono-layer graphite oxide alkene, multilayer graphene oxide or the mixture of the two, deacetylating degree of chitosan 70-80%, molecular weight 50,000-200,000, the molecular weight 40 of wool keratin, 000-50,000.Crosslinking agent is one or more in glyoxal, glutaraldehyde, ethylene glycol diglycidylether, pyridine.Ultrasonic processing time 1-48h.Freeze drying process condition is: the speed of take under the temperature conditions of-50 ℃～-30 ℃ is warming up to room temperature as 1-3 ℃/min, the drier 10-40 h that processes.
Compared with prior art, advantage of the present invention is: the raw material of employing is all renewable, cheap and easy to get, and the filtrate of preparation has three-dimensional porous structure, good mechanical strength, renewable, easy degraded, environmental protection and efficient adsorption.
