Summary of the invention
The object of this invention is to provide a kind of endurance quality and the excellent flexible air purifying material preparation method of anti-photooxidation degradation property.
The present invention is achieved by the following technical programs: a kind of flexible air purifying material preparation method, comprises nanometer Fe-TiO
2the preparation of-La suspension and nanometer Fe-TiO
2the preparation of-La carrying fiber fabric, described nanometer Fe-TiO
2the preparation process of-La suspension is for taking 10g nanometer Fe-Ti0
2-La powder, in 600ml beaker, adds deionized water and uses ultrasonic oscillator process 3h, then adds 0.4g dispersant ME and 0.3g hyper-dispersant 27000, mechanical agitation 45min, obtains the oyster white water slurry 250mL of stable and uniform; Described nanometer Fe-TiO
2the preparation process of-La carrying fiber fabric comprises (1) fabric preliminary treatment, fabric is soaked 30min in acetone soln, then at room temperature dry, take out after padding the anti-oxidant dressing liquid 30min of cotton fiber, at 80 DEG C of preliminary dryings, be warming up to 150 DEG C again and bake 2min, prepared by (2): nanometer Fe-TiO
2-La suspension, silicone additives 25g/L, JFC wetting agent 3g/L, is immersed in nano-TiO by fabric sample
2in finishing agent, two leachings two are rolled (room temperature, pick-up rate 75%), take out after 5min, at 100 DEG C of preliminary dryings, then are warming up to 160 DEG C and bake 2min, be cooled to room temperature, obtain finished product.
The present invention has following beneficial effect:
Adopt flexible air purifying material prepared by this preparation method, under visible ray effect, can the toxic gases such as indoor formaldehyde be eliminated, play the effect purified the air of a room; Again can protectiving ultraviolet radiation, the safety of protection indoor human body and object, reusable, endurance quality and anti-photooxidation degradation property high, be with a wide range of applications.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention will be further described.
Specific embodiment: preparation process of the present invention comprises nanometer Fe-TiO
2the preparation of-La suspension and nanometer Fe-TiO
2preparation two step of-La carrying fiber fabric, described nanometer Fe-TiO
2the preparation process of-La suspension is for taking 10g nanometer Fe-Ti0
2-La powder, in 600ml beaker, adds deionized water and uses ultrasonic oscillator process 3h, then adds 0.4g dispersant ME and 0.3g hyper-dispersant 27000, mechanical agitation 45min, obtains the oyster white water slurry 250mL of stable and uniform; Described nanometer Fe-TiO
2the preparation process of-La carrying fiber fabric comprises (1) fabric preliminary treatment, fabric is soaked 30min in acetone soln, then at room temperature dry, take out after padding the anti-oxidant dressing liquid 30min of cotton fiber, at 80 DEG C of preliminary dryings, be warming up to 150 DEG C again and bake 2min, prepared by (2): nanometer Fe-TiO
2-La suspension, silicone additives 25g/L, JFC wetting agent 3g/L, is immersed in nano-TiO by fabric sample
2in finishing agent, two leachings two are rolled (room temperature, pick-up rate 75%), take out after 5min, at 100 DEG C of preliminary dryings, then are warming up to 160 DEG C and bake 2min, be cooled to room temperature, obtain finished product.
In finished product nano titanium oxide through iron and lanthanum co-doped after, effectively reduce nano titanium oxide band gap and light induced electron and hole-recombination probability, improve its photocatalytic activity, make fabric face loading nanometer Fe-TiO
2-La with regard to the indoor contaminated gas of energy photocatalysis Decomposition, changes TiO for a long time under visible light conditions
2photodegradation is to the dependence of intensive ultraviolet.
Sem analysis is carried out to finished product, compared with the smooth surface of cotton fiber, nanometer Fe-TiO
2-La load cotton fiber surface is very coarse, has particulate matter to exist, and shows slightly uneven, proves that nanometer Fe .Ti02_La has been attached to cotton fiber surface.
Carry out anti-ultraviolet property test to finished product, its Ultraviolet Protection Factor UPF reaches 43.05, and ultraviolet ray transmissivity is less than 2.5, therefore has good anti-ultraviolet property.
Centrifugal test is carried out to finished product, centrifugation time is respectively 1min, 3min, 5min, 7min, last 350W xenon lamp of using in photochemical reaction instrument irradiates 10h, carry out photocatalysis Decomposition formaldehyde contrast test, result is as follows, the flexible air purifying material clean-up effect prepared all decreases with the prolongation of centrifugation time, and after centrifugal 9min, its air purification effect declines 6.4%.The revolution of current washing machine is generally less than 800r/min, illustrates that preparing flexible air purifying material has good fastness to washing, is that COTTON FABRIC is applied to sanitizer cartridge exterior material key.
Flexible air purifying material prepared by the method for the invention, under visible ray effect, can eliminate the toxic gases such as indoor formaldehyde, play the effect purified the air of a room; Again can protectiving ultraviolet radiation, the safety of protection indoor human body and object, reusable, endurance quality and anti-photooxidation degradation property high, be with a wide range of applications.
Above content is the further description done the present invention in conjunction with concrete embodiment, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, some simple deduction or replace can also be made, all should be considered as belonging to protection scope of the present invention.
