Description
Technical field
The invention belongs to the finishing field of fabric, particularly to a kind of preparation method of the jacquard fabric removing formaldehyde.
Background technology
With the lifting to Dwelling Environment quality for the people, house fitting is also increasingly luxurious.While finishing, the body of people
Heart health also will face huge challenge, and wherein formaldehyde gases pollution is most serious.In indoor air formaldehyde essentially from：One
Adhesive inside a little sheet materials；Add the related auxiliaries of aldehydes in coating；The heat-barrier material of Lauxite processing；Detergent, change
The articles for daily uses such as cosmetics, anticorrosive additive, paint and yarn fabric.Therefore the floor of finishing, wood furniture, veneer, bonding paster
Deng discharging formaldehyde, general acquisition time is up to 3～15 years, causes long-term healthy and safe hidden danger.
Formaldehyde has very strong stimulation, sensitization and mutagenesis harm, when people are in concentration of formaldehyde 0.06mg/m3~
0.07mg/m3It may appear that asthma；Concentration is in 0.1mg/m3～2.0mg/m3, people can smell abnormal smells from the patient substantially；Concentration is in 0.5mg/
m3, eyes do not feel well；Reach 0.6mg/m3When, cause the uncomfortable of throat and pain；Concentration is in 2.0mg/m3～5.0mg/
m3, the phenomenons such as cough, sneeze in the position such as respiratory tract；Concentration reaches 3.0mg/m3, human body will feel vomiting, nausea, breast
The symptoms such as vexed, emphysema, asthma；When concentration is in 100mg/m3When above, human body suck 5min～10min then entail dangers to property
Life, Health Impact is as shown in table 1 with concentration of formaldehyde horizontal relationship.
Table 1 Health Impact and concentration of formaldehyde horizontal relationship
Currently, the Related product of room Formaldehyde Pollution Treatment is also born in succession, administers Formaldehyde Pollution of Indoor Air more in family
Conventional has air purifier, puts plant, physical absorption, negative oxygen ion, material closing, catalytic degradation, and particularly oxidation is urged
Change, Formaldehyde decomposition can be carbon dioxide and water by current purifying formaldehyde material to a certain extent, and the method power consumption is few, makes
With life-span length, degradable organic pollutant can be circulated, this direction that always people are studied.
Ventilation.Need the frequent door window of people, carry out gravity-flow ventilation it is also possible to buy ventilator or on the market heat
Air purifier of pin etc. carries out forced ventilation or filtering contaminants, and the method is effective when outdoor pollution level is lighter, but
In the case that pollution level is heavier, this method does not have much effects substantially.
Plant purification acts on.Plant also has certain clean-up effect to indoor formaldehyde, such as Epipremnum aureum (Linde et Andre) (Bunting.), bracketplant, Aloe, arrow leaf
Taro, Budgerigar orchid etc. all have certain purification assimilation effect to the formaldehyde in room, and plant has very on pollutant degree of absorption
Big difference, the effect that this method purifies slowly and is not it is obvious that quickly can not be removed to the content of formaldehyde in room.
Physical adsorption techniques.By organic pollutions such as some material formaldehyde adsorption.General family adopts activated carbon, diatom
The physical methods such as mud, coconut husk, aluminium oxide, zeolite, meerschaum are adsorbed, convenient, inexpensive, but the capacity of physisorption material
It is limited, adsorbance needs to change in time after reaching saturation, otherwise can impact effect；The diatom ooze being coated in material surface is thick
Degree is thicker, and construction is inconvenient, of long duration easy to fall off, can not recycle and reuse, and replacement cost is higher.
Negative aeroion technology.Mainly pass through the rare mineral (anion being possible to produce thermoelectricity or piezoelectric effect
Powder) it is added in ornament materials, cause the water in indoor environment to be ionized by this ornament materials, and discharge negative oxygen ion, catalysis
The organic pollutions such as oxidation of formaldehyde, organic pollution in degraded room, improves air quality further.
Material sealing technique.Mainly pass through a kind of sapecial coating of surface-coated in furniture and artificial board, thus shape
Become one layer of fine and close film, the polluter such as formaldehyde have been closed, reached the purpose reducing burst size, the method has prepared film
Relatively costly and cure the symptoms, not the disease it is impossible to thoroughly decompose formaldehyde, therefore nor extensive apply.
Photocatalysis oxidation technique.Have that reaction is gentle, environmental protection, the features such as inexpensive and degradation capability is strong, oxidation-degradable first
The Organic substances such as aldehyde are CO2And H2O etc..But, there are some problems and cause photocatalysis efficiency ratio relatively low, so catalysis material one
It is directly the emphasis studied in recent years, therefore attention.
Nano-TiO2Grain diameter very little, has very big specific surface, the internal existing defects of its key state, electronic state and granule,
Its surface activity point potential energy is enough to be sharply increased with the reduction of particle diameter.Nano-TiO2There is avirulence, low price, table
Face activity is big, catalytic action is compared with strong and the features such as absorbing properties are good.It typically has three kinds of crystal formations：Detitanium-ore-type TiO2, gold
Red stone-type TiO2With brookite type TiO2, wherein the former two is main crystal formation.Due to crystalline structure difference, lead to their thing
Reason, chemical property and application aspect there is also a certain distance.Detitanium-ore-type TiO under visible short2Reflectance be higher than
Rutile-type, assumes blue color it is considered that its energy gap is more bigger than rutile-type, and it is scarce to present crystalline surface
Fall into, therefore its photocatalytic activity is stronger relative to rutile-type, be widely used in pottery and fiber, photocatalysis functional material and give up
Water pollutant inorganic agent etc..Rutile TiO2Have that covering power is good, intensity is high, dielectric constant is high, high index of refraction etc., and right
The absorption phase of ultraviolet is to anatase type nano TiO2Relatively strong, it is commonly used for the fields such as car paint, sunscreen cream and delustering agent.
Nano-TiO2It is a kind of semiconductor nano material, fill up the valence band (VB) of electronics and empty conduction band (CB) constitutes it and can carry, 3.2ev
Energy gap, when being more than or equal to energy gap with luminous energy and irradiating, the electronics in valence band transits to absorbing luminous energy conduction band and goes out
Existing light induced electron (e-), and photohole (h is produced on valence band+), form electric field, light induced electron and photohole all move to grain
Sublist face, generates (e--h+) right.h+Electronics ability very strong, that is, its oxidisability is especially strong, can make nano surface
TiO2OH-And H2O is oxidized to OH.Wherein, to have oxidation efficiency high, reaction rate fast and non-selective etc. excellent for the OH of generation
Point, so that the oxidation catalytic activity of nano titanium oxide is improved.
Concrete mechanism process is as follows:Nano-TiO2It is subject to more than TiO2During the light irradiation of energy gap (Eg=3.2eV), electricity
There is following reaction in son migration：
TiO2+hv→TiO2(e-)+TiO2(h+)
TiO2(h+)+D→D+(vacancy complexes)
TiO2(e-)+A (electron acceptor) → A-
H2O reacts after losing electronics and produces hydroxyl (OH), and its process is as described below：
TiO2(h+)+H2O→·OH+H+
TiO2(e-)+O2→O2 –
O2 –+H+→HO2·
2HO2·→H2O+O2
H2O2+O2–→·OH+OH-+O2
H2O2+hv→2·OH
h++OH-→·OH
OH+org (organic pollution such as formaldehyde, toluene)+O2→H2O+CO2
From nano-TiO2Under the conditions of mechanism understands ultraviolet or the irradiation of sunlight, go out photohole using photon excitation, its
Oxidability is very strong, the hydrone oxidation of titanium dioxide surface can be generated the OH with strong oxdiative power.And the height of OH
Oxidation activity, can destroy rapidly C-O, C-C, C-H, C-N in the air organic pollutants such as the formaldehyde on its surface for the absorption, toluene
Deng chemical bond, finally it is broken down into CO2、H2O etc..
Due to nano-TiO2Particle diameter is less than 100nm, and surface tension is larger, has very strong polarity, in aqueous easily
Reunite, thus leading to its photocatalysis performance to be greatly reduced；One side nano-TiO2There is substantial amounts of defect in surface, be difficult to
Disperse in dressing liquid, cause rough coating uneven, make electron hole and electronics composite pathway increases growth, recombination probability rises,
So that hole concentration is reduced, so that photocatalytic process hydroxyl radical free radical is reduced, also will reduce the degradation capability of film.On the other hand receive
Rice TiO2Specific surface big, can be high than table, surface dead key more so that thermodynamic instability in system, exist certain between granule
Active force it is easy to make Nanosurface particle agglomeration, so that the monodispersity of system is deteriorated, rough coating is uneven, cause a large amount of
Electron hole pair is combined and loses catalytic purification ability, has a strong impact on its photocatalysis performance it is therefore desirable to process nano-TiO2?
