The preparation method and its application on lamps and lanterns that the present invention provides a kind of copper ion-photo-catalytic sterilization taste removal film, by copper ion with and photocatalyst material by Cu/Ti molal weight percentage be 0.009~0.05 compound to obtain copper ion-photocatalyst composite material；Bacterium eliminating smell agent slurry is made in composite material and distilled water-dehydrated alcohol preparation slurry ultrasound, and copper ion-photo-catalytic sterilization taste removal film is made through heating after coating.Copper ion itself has bactericidal effect in the present invention, and under no light condition, material film equally has sterilizing deodoring performance；Copper ion doped photocatalyst photochemical catalyst can almost decompose any organic matter, and it not will cause secondary pollution, low energy consumption, material itself is lossless, in conjunction with the water and oxygen generation redox reaction in air, and the hydroxyl free radical of strong oxidizing property is formed on surface, so as to reach air cleaning, sterilization, deodorization and mould proof effect for the organic matter and the substance decompositions such as pernicious gas in air.
Description
Technical field
The present invention relates to photo-catalytic sterilization taste removals, and in particular to a kind of preparation of copper ion-photo-catalytic sterilization taste removal film
Method and its application on lamps and lanterns.
Technical background
Health substantially air, and in the atmospheric environment of our daily life and works all can exist much to body not
The toxic and harmful gas of benefit.Volatile organic contaminant is divided into four classes in indoor environment: highly volatile organic matter (VVOCs),
Volatile organic matter (VOCs), semi-volatile organic matter (SVOCs) and organic matter related with particulate matter or particulate organic matter
(POM), the pollution situation of organic matter is substantially represented with VOCs in the context of detection to indoor organic pollutant.Beauty in 1989
Bureau for Environmental Protection, state layer detects that there are indoor VOCs in more than 900.The source of VOCs is mainly by Building wood in indoor environment
What material, detergent, paint, aqueous coating, adhesive, cosmetics and detergent etc. released, furthermore also can in smoking process
It generates.
Due to people's production and life activity, so that certain micro-organisms may be present in air, including the micro- life of some cause of diseases
Including object, and cause by air the propagation of disease.Especially in the crowded environment of improper ventilation, personnel, room air is had
More microorganism exists.The indoor environment of mankind's activity includes being related to the office of the various aspects such as work, learning recreation, shopping
The various places of the relative closures such as room, classroom, gymnasium, hospital, office building.There is 70 ~ 90% time in all one's life of people in room
It inside tides over, therefore indoor environmental quality influences considerably beyond outdoor environment people's lives and work quality and health,
Therefore harmful substance in room air how is killed, such as the first generated in the formaldehyde that releases of ornament materials and living environment
The volatile contaminants such as mercaptan and all kinds of pathogenic bacteria become people and increasingly ask with concern topic.
Photochemical catalyst is otherwise known as photocatalyst, and the system of the chemical substance of catalytic action can be exactly played under the excitation of photon
Claim, a variety of Disciplinary Frontiers such as the depollution of environment, self-cleaning material, advanced new energy, high-efficiency antimicrobial can be applied to.Trace meter from
The doping of son can significantly change the micro-structure of Nano Titanium Oxide as Photocatalyst film surface, substantially increase film and electrolyte
Contact interface creates extremely advantageous condition in the transmission of solid liquid interface for carrier, and something which increases thin
The photoelectric properties of film keep the photocatalysis performance of film more prominent；In addition, part metals ion itself has bactericidal effect, in nothing
Under the conditions of light, material film equally has sterilizing deodoring performance.Photochemical catalyst can almost decompose any organic matter, and will not make
At secondary pollution, low energy consumption, and material itself is lossless, thus catalysis material using more and more extensive.The prior art
The patents such as CN201340037, CN102980068, CN2695784, CV201429058 and CN102840565 have been presented for one kind
Household air-purifying lamp is mainly utilized on the light source of lamps and lanterns and increases ultraviolet band, irradiates photocatalysis by ultraviolet light
Agent coating realizes light catalytic purifying function.Although prior art is able to achieve Air purification, but due to having used purple
Outside line lamp, be easy to cause ultraviolet light to leak outside, and ultraviolet light has serious damage to the skin and eyesight of the mankind, therefore is not indoor
The preferred plan of purification.
Summary of the invention
In view of the above-mentioned drawbacks of the prior art, the purpose of the present invention is to provide: a kind of copper ion-photo-catalytic sterilization
The preparation method of taste removal film and its application on lamps and lanterns.
To achieve the above object, the technical solution used in the present invention is: providing a kind of copper ion-photo-catalytic sterilization taste removal
The preparation method of film and its application on lamps and lanterns, the copper ion-photo-catalytic sterilization taste removal film, by copper ion and and light
Catalyst material is combined by Cu/Ti molal weight percentage for 0.009~0.05.
A kind of preparation method of copper ion-photo-catalytic sterilization taste removal film, the preparation method comprises the following steps:
(1) TiCl of a, 0.5 mol/L of measurement490 mL of solution is in 70 DEG C of 30 min of magnetic agitation, according to preset blending ratio (SiO2
Mass percentage content 5%, 10%, 15%, 20%, 30%) Na of 0.3 mol/L is slowly added dropwise2SiO3Solution, completion of dropwise addition continue
Stir 20 min；
B, it weighs Cu/Ti molal weight percentage and is 0.009 ~ 0.05% copper nitrate, and be dissolved in 15 mL dehydrated alcohols, in magnetic
Under the stirring of power blender, it is slowly added dropwise in the mixed solution obtained by previous step with 1 drop/s rate；
C, 3 mol/L ammonia spirits are slowly added dropwise and adjust pH value to 5.15, so that solution is generated precipitating, is aged 20h；
D, the mixed solution stirred evenly is placed in microwave synthetic reaction instrument, 130~150 DEG C of temperature, 100~150 W item of power
20~40 min are reacted under part, both obtain copper ion-photocatalyst (Cu after reaction2+/TiO2—SiO2) composite material；
(2) it weighs the material that 2~5 g appeal prepares to be added in 100 mL beakers, by distilled water and dehydrated alcohol according to quality
