Description
Technical field
The present invention relates to one kind except chinampa can be recycled in formaldehyde, and in particular to a kind of photocatalysis is artificial except formaldehyde can be recycled
Lawn belongs to nano photo catalyzed oxidation field.
Background technique
With being constantly progressive for society, people's living standard is also being promoted, therefore recyclability and environment peace for material
Full requirement is more stringent.It is the focal point of modern resident for indoor finishing.Formaldehyde is desk research
Very high a kind of easily the waving property organic matter of middle attention rate, since it is well used in construction material such as adhesive, coating；Cleaning
Also fecund gives birth to formaldehyde in the daily chemical products such as agent, insecticide, disinfectant；In addition, room air pollution can also cause indoor formaldehyde dirty
Dye, therefore indoor pollution caused by formaldehyde is relatively conventional.And in newly-decorated house, formaldehyde is primary pollutant.Formaldehyde
It is a kind of colourless gas for having intense irritation smell under room temperature, it is soluble easily in water, it is one of potential carcinogen generally acknowledged in the world.
The main harm of indoor formaldehyde is embodied in the stimulation to human skin mucous membrane, and the formaldehyde olfactory threshold of people is 0.06-
0.07mg/cm3, national standard " Indoor Air Quality standards " regulation indoor formaldehyde concentration limit value is 0.01mg/cm3(1 hour flat
Mean value), and 0.15mg/m3Concentration of formaldehyde can cause cough, asthma, eye is itched, have hot coppers is itched, hoarseness, skin
Drying is itched and the malaise symptoms such as dermatitis.
Meanwhile the science and technology in China is constantly developing, there has also been many achievements in terms of handling indoor air purification.Just
It is relatively common at present to have filtering, absorption and anion, UF membrane etc., the characteristics of they possess itself, in clean room
Interior air also has the apparent effect of performance, but is most surely belonged to nano photo catalyzed oxidation by people's favor now, it is mainly sharp
With visible light, the elimination of micro-organisms and photodissociation escaping gas, solve indoor pollution from source in normal environment.In recent years
Come, the photocatalyst applications such as titanium oxide are in outdoor, on substrate surface by using photocatalyst, assign and utilizing to substrate
The decomposition function of the harmful substances such as NOx/Sox, the formaldehyde of luminous energy leads in addition, the surface for the clear water that light becomes when irradiating has
Cross and rinse the so-called self-cleaning function of attachment dirt.As indoor utilization, by making photocatalysis be supported on substrate surface
On, the decomposition function using harmful substances such as luminous energy VOC is assigned to substrate, or assign antibacterial functions, antimildew function, antiviral function
Energy.Photocatalysis basic principle is that have the photo-generate electron-hole of theory property theoretical, wherein most study is done with semiconductor
Catalyst.With TiO2For, with discontinuous band structure, it is collectively constituted by higher energy conduction band and low energy valence band, and is prohibited
Band refers to the region between conduction band and valence band, width Eg=3.2eV, and just by taking this standard as an example, when wavelength is less than
When 380nm irradiates surface, valence-band electrons can absorb energy, can thus generate transition phenomenon, wait until to lead after conduction band
Valence band hole is caused, electron-hole pair is ultimately formed, and if when such situation time long enough, typically selection use
High-energy electron can regard reducing agent, whereas if the low hole of electronics is then used as oxidant, when it and TiO2Adsorption
Pollutant occur redox reaction when, reach the processing to pollutant, it made to be degraded to water and CO2.Largely grind
Studying carefully in terms of showing photochemical catalyst to benzene, formaldehydes contaminant degradation has huge application prospect, such as utilizes the multilayer knot of clear opening
Structure honeycomb entirety purifying net, theme is by supporter, active carbon and TiO2Photochemical catalyst composition, it is right to show by practical application
The purification of benzene, formaldehyde and ammonia is above 95%, and effect is very good.
Photocatalysis technology has the advantage that (1) reaction condition is mild relative to other technologies such as filtering, absorption,
It is carried out under normal temperature and pressure；(2) reaction rate is fast, and required time is short；(3) majority of organic pollutants can be degraded to small molecule object
Matter.Using chinampa made of nano-photocatalyst material, the infringement of tradition finishing substance can be avoided, to harmful in air
Gas not only good purification, and degradation rate is also high, shows strong oxidizing property.Patent CN104727202A discloses one
Kind recyclable chinampa and preparation method thereof, the chinampa have whole recyclable, and environmental protection does not use glue, not the row of beating
The remarkable advantages such as proper drainage and high withdrawal force can be realized in water hole, but the chinampa is only on movenent performance with excellent
Gesture, but there is no specific function in terms of comparing environment purification, such as remove the function of formaldehyde.Patent CN107009631A is disclosed
A kind of integrally recyclable chinampa, the recyclable chinampa mainly solve cluster in original chinampa production process
The problem of suede difficulty improves production efficiency, also discloses the different system in combination of different woven fabrics, improve whole lawn
Withdrawal force, the recyclable chinampa patent focus are equally the mechanical properties on lawn itself, which does not have
Purify the function of air.
Summary of the invention
In view of this, keeping lawn formedness the present invention provides a kind of photocatalysis except chinampa can be recycled in formaldehyde
Assign chinampa special function while energy.The chinampa promotes NOx/SOx, formaldehyde etc. for outdoor, using luminous energy
The decomposition of harmful substance, in addition, the hydrophilic surface that light becomes when irradiating has the so-called self-cleaning function for rinsing attachment dirt；
As indoor use, promote the decomposition of the harmful substances such as VOC using luminous energy, and can realize recycling and reusing, it is environmentally protective.

Wear-resisting inspection is carried out to lawn using standard FIFA Quality Programme for FootballTurf-2015
It surveys, is detected using Lisport XL chinampa abrasion meter, careless silk specification is width about 13mm, about 200 μm of thickness, about
2000 Denier.
Embodiment 5-14 and comparative example 4-5, the partial size and additive amount of different inorganic catalysis materials are to careless silk withdrawal force
There is different influences, specific data are shown in Table 4.
Withdrawal force performance is detected using standard GB/T 1090-2001, tests careless silk using omnipotent test puller system
Whole cluster and single withdrawal force, 10 groups of withdrawal forces of test are averaged, and lawn is singly to knit chinampa, and careless silk specification width is about
About 200 μm of 13mm, thickness, about 2000 Denier.
The wear-resisting data of pull-off force and lawn of the careless silk of table 3
