Description
Technical field
The present invention relates to a kind ofly be used for the bacteriostatic agent of air-conditioning filter net and have the preparation method of the air-conditioning filter net of bacteria resistance function, be specifically related to the preparation method of a kind of Nano Silver air-conditioning filter net bacteriostatic agent and Nano Silver air-conditioning filter net.
Background technology
Along with the raising day by day of people's living standard, can be the central air-conditioning that the air-conditioning that people bring a home from home, particularly public place generally use and generally be used for daily life and work.But, because the filter screen of air-conditioning inside creates suitable condition can for growth of bacterium and breeding, therefore, when air-conditioning work, bacterium on its filter screen (as Legionella etc.) very easily pollute room air through air exchange, thus people's health is constituted huge threat.
Present treatment measures to air-conditioning filter net mainly contain in chemical bactericide sterilization, ultra violet lamp or the filter screen adds activated carbon, but chemical bactericide disposable sterilization and bacterium often is easy to generate drug resistance and makes a variation, and the toxic composition that volatilizees easily; Symptoms such as the ultra violet lamp method is by air is produced ozone by ultraviolet irradiation, thereby plays bactericidal action, produces headache but the long-term existence of ozone can cause human body, and is uncomfortable in chest; Though and the bacterium of the adsorbable some of activated carbon, and contaminated air does not just have ability to stop breeding and the growth of bacterium when its absorption reaches after full.
For overcoming the defective of conventional method, people are developed the air-conditioning filter net bacteriostatic agent that multiple other form, for example, the invention in Chinese patent publication number CN1580219, open day on February 16th, 2005 proposes a kind of long-acting air conditioning purge agent, it is by adding surfactant in water, film forming agent, bactericide etc. and make.But the bactericide that adopts in this clarificant is bactericide such as quaternary ammonium salt, imidazoline, and its sterilization mechanism is a chemism, so the air conditioner filter screen of wherethrough reason causes secondary pollution easily.Again for example; the invention in China Patent No. ZL200510062319.8, open day on July 19th, 2006 proposes a kind of preparation method of inorganic material carried nanometer silver sol; it is by after dissolving silver nitrate; add inorganic nano material colloidal sol, protectant, stabilizing agent and reductant successively, thereby make inorganic carrier nano silver colloidal sol.It is online that this colloidal sol can be applied to air conditioning filter, but this colloidal sol is difficult to evenly spray to the air conditioner filter screen surface, thereby make its antibacterial bacteriostatic effect relatively poor, and if the method by improving quantity for spray to increase the cover degree of this colloidal sol on the screen pack surface, then often causes increasing substantially of cost.
Summary of the invention
The objective of the invention is to propose a kind of fiber to be had excellent permeability, wetability and wetability again, and preparation method with air-conditioning filter net bacteriostatic agent He this bacteriostatic agent of persistent high efficiency fungistatic effect, and a kind of technology is succinct, with low cost, and can make air-conditioning filter net have the preparation method of the air-conditioning filter net of persistent high efficiency bacteriostasis property, to overcome deficiency of the prior art.
For achieving the above object, the present invention has adopted following technical scheme:
