Description
Technical field
The invention belongs to materialogy field, is related to a kind of filter cotton, a kind of specifically gas containing graphene oxide
Body filter cotton and preparation method thereof.
Background technology
Although nowadays the trend of air pollution is suppressed under the improvement energetically of country, the air of China part
Still the health to human body constitutes a certain degree of threat, and especially the case of PUD D is more and more.The scope of activities of people
Mainly family and workplace, it is contemplated that maintain excellent air quality, need to carry out certain air circulation, and to circulation
Air carries out filtration, purification, and this is accomplished by using filter cotton.The mainly pure filter cotton that now applies on the market, in order to dust-proof or
Activated carbon filter cotton filtration fraction pernicious gas.
Activated carbon filter cotton is carrier using the aluminium honeycomb of through-hole structure, plastic honeycomb, paper honeycomb, it is adaptable to air filtration
System fine filtering and high efficiency particulate air filter are filtered.Its suitable carrier scope is narrower, and it cannot be guaranteed that can be uniformly dispersed in load
In body, it is difficult and carrier collaborative filtering gas, and its activated carbon dosage is more, it is also contemplated that the combination degree with carrier, these
The use of activated carbon filter cotton is all limited.It is thus desirable to exploitation one kind more efficient evenly can be disperseed in the carrier, carrier
The scope of application is wider, and quality is lighter, it is possible to act synergistically with carrier, resource-effective filter cotton packing material.
Presently disclosed patent mainly has：
A kind of activated carbon filter cotton of the Yu Xiaodong invention of Fengqiao Purifying Equipment Factory, xin District, Suzhou, the patent No. 201410036615,
The patent is uniformly distributed in activated carbon granule inside filter cotton, and the top surface of filter cotton and bottom surface are all bonded with protection film layer.
In activated carbon filter cotton obtained in the method, the degree that is evenly distributed of activated carbon is relatively low, and is combined defective tightness with filter cotton.
The novel absorbent charcoal fiber filter cotton of Yang Jianjun of Jiangsu Kejing Carbon Fiber Co., Ltd. et al. invention, the patent No.
201320102790, the patent filter cotton includes upper and lower terylene layers, arranges 1-2 layer between upper and lower terylene layers
Activated carbon fiber layers.The method preparation technology needs interlayer to arrange activated carbon fiber layers, it is impossible to effectively cooperateed with layers
Filter.
A kind of efficient air filter wool of the Lv Zesheng invention of Hangzhou DEESTAR Fiber Technology Co., Ltd., the patent No.
201020290772.Filter cotton in the patent includes upright cotton layer, and its bottom surface is compounded with layer of meltblown fibers, described upright cotton
Layer is that the compound layer of meltblown fibers in bottom surface is ultra-fine fiber construction through cuing open the upright cotton of layer process, in order to catch dust granules
Filtration, the filter cotton need to add new operation in filter cotton preparation technology, increased preparation complexity, and not
Can effective filtering poisonous gas.
A kind of New type filtering cotton of the Wang Zheng invention of Dongguan Lianying Cotton Products Co., Ltd, the patent No.
200820178490.The New type filtering cotton includes acupuncture cotton and fibrefill, acupuncture cotton and fibrefill multilayer cross lamination, its
Fibrefill is terylene, and the method effectively can not be filtered to pernicious gas.
In sum, current filter cotton all exist can not effectively filtering noxious gas, or filler skewness,
Can not be with the problem of carrier cooperation-removal pollutant.Therefore little in the urgent need to seeking a kind of bulk density, specific surface area is big, absorption
Efficiency high, can be widely used for processing containing the organic gas for being unfavorable for health and working environment and containing dust and micro
The filter cotton of all kinds of gases of heavy metal, or Adsorption Concentration can be carried out to waste gas, purify after the filter cotton that directly can discharge.
This preparation technology is namely based on these theories and researches and develops making.
