Abstract
The invention discloses formaldehyde in air, abnormal flavour material and preparation method thereof in a kind of deaeration car based on kieselguhr micropowder, belong to diatom technical field of nano material.Solving and remove formaldehyde in automobile inner air, the material of abnormal flavour and method in prior art to there is purification efficiency low, clean-up effect persistency is low, it is impossible to produce anion and moisture absorption, the technical problem of wet putting difference.The present invention except first abnormal flavour aldehyde material in automobile inner air, it is made up of the coating of label and cladding label, wherein, label is made up of water, kieselguhr micropowder and redispersable latex powder, and coating is made up of nano titanium dioxide/diatomite composite catalyzing material and redispersable latex powder.In the deaeration car of the present invention, formaldehyde in air, abnormal flavour material can not only remove the formaldehyde in automobile, gas with foreign flavor, improve automobile inner air quality, also there is anion releasing, purify air, the effect of adjusting air humidity, can be applicable to formaldehyde, the gas with foreign flavor removing in automobile.
Description
Technical field
The invention belongs to diatom technical field of nano material, be specifically related to a kind of based on kieselguhr micropowder remove
Formaldehyde, abnormal flavour material and preparation method thereof in automobile inner air.
Background technology
Along with the fast development of national economy and stepping up of people's living standard, automobile becomes increasingly popular.
For the comfortable of automobile and realize automobile partial properties, a large amount of ornament materials in automobile, can be used.These decorations
Material mostly is plastic, so causing the severe contamination to environment inside car, and serious threat occupant
Healthy.In car, noxious substance mainly has formaldehyde, benzene,toluene,xylene, TVOC (general volatile
Organic compound).Wherein, the pollution of formaldehyde is the most serious, and the harm to human body is the most maximum.Formaldehyde is a kind of
The toxic gas of irritant abnormal smells from the patient, the impact on human body includes heterosmia, stimulation, allergy, pulmonary function
Exception, abnormal liver function, immunologic dysfunction, central nervous system are impacted.Exciting eye at low concentrations
Film, stimulates upper respiratory tract when concentration is slightly higher, cause cough, uncomfortable in chest, have a headache, nauseating, draw when concentration is higher
Play rhinitis, pharyngitis, emphysema, even dead, there is carcinogenic, teratogenesis, mutagenicity, thus in automobile
Formaldehyde harm has caused the extensive concern of people.
At present, conservative control and the concentration of formaldehyde effectively reduced in automobile inner air have become as vapour environment inside car
One important content of protection.In prior art, in automobile, the administering method of formaldehyde pollution mainly uses absorption
Method or photocatalytic method.Absorption method is single frequently with porous adsorbates such as natural clay, molecular sieve, activated carbons
Or compound use, and these material bulk density are low, and specific surface area is big, so having stronger adsorption function,
Have cheap, quickly, the feature such as removable multiple inorganic, organic pollution, but shortcoming is that easily absorption is full
With, easily desorption thus cause secondary release to be polluted, PARA FORMALDEHYDE PRILLS(91,95) is without specially imitating selectivity, the most affected by environment.Light
Catalysis method typically uses titanium dioxide (TiO2) etc. semi-conducting material, through ultraviolet excitation, decomposable asymmetric choice net major part has
Organic pollutants.But, in automobile, ultraviolet irradiation intensity is relatively low, actually used middle inefficiency.Existing skill
In art, also do not have a kind of based on photocatalytic method can be the most lasting remove the material of formaldehyde gas in automobile
Material.Also utilize plant or fruit peel to remove the method for formaldehyde in automobile, but the absorption property of plant is very
Weak, and place in the car, take up room.
To sum up, it can be seen that the method for formaldehyde in automobile that removes in prior art has certain effect, but
It is that the purification efficiency of the toxic gas such as its formaldehyde is the highest, and clean-up effect persistency is the highest, and cannot produce
Raw anion, moisture absorption, wet putting are poor.And current, owing to technology and material are limited, manufacturing automobile process
In also cannot total ban use containing the raw material of formaldehyde components, the most just cannot remove formaldehyde from source
Harm, therefore, how eliminating and reducing formaldehyde harm is the task of top priority.

The gas such as formaldehyde, abnormal flavour is formaldehyde in air, the degraded point of abnormal flavour material surface in the deaeration car of the present invention
Being two processes, one is the gas molecule such as formaldehyde, abnormal flavour formaldehyde in air, abnormal flavour material list in deaeration car
Face is adsorbed, and two is absorption gas such as formaldehyde in air, the formaldehyde of abnormal flavour material surface, abnormal flavour in deaeration car
Molecule is under light illumination by optical active substance nano titanium dioxide degradable.When energy exceedes nano titanium oxide forbidden band
The photon irradiation of width in deaeration car formaldehyde in air, abnormal flavour material constituent nano titanium oxide/
During diatomite composite photocatalytic material surface, the electronics being in nano titanium oxide valence band will be excited to lead
On band, thus in valence band and conduction band, produce light induced electron and the hole that high activity moves freely respectively.Due to
The nano titanium oxide of nano titanium dioxide/diatomite composite photocatalytic material area load is nanometer particle,
Therefore light excites the electronics of generation and the hole can be quickly from vivo migration to surface, hole is strong oxidizer, can
So that the absorption hydroxyl on nano titanium oxide surface and water are oxidized to OH；And conduction band electron is strong reductant,
It is attracted to the dissolved oxygen capture on nano titanium oxide surface and is formedPartChain type can be continued through
Reaction generates OH.Generate OH andThere is stronger oxidisability, it is documented, nano-silica

Thing all kinds of chemistry bond energy, such as: C-C (83), C-H (99), C-N (73), C-O (80), N-H (93), H-O (111)
Deng, thus generate OH andThe c h bond of the gas such as formaldehyde, abnormal flavour, H atom active with it can be attacked
Produce new free radical, excite chain reaction, finally make the gas such as formaldehyde, abnormal flavour be decomposed into harmless tasteless substance.
During nano titanium dioxide/diatomite composite photocatalytic material Photo-Catalytic Degradation of Formaldehyde, activity OH
WithCommon Oxidation, is first oxidized to formic acid by formaldehyde gas, is finally decomposed to water and carbon dioxide.
Its decomposition mechanism is as follows:
HCHO+·OH→·CHO+H2O
·CHO+·OH→HCOOH
Formaldehyde in air, abnormal flavour material in the deaeration car of the present invention, place in the car, can persistently catch
Formaldehyde, gas with foreign flavor, even if the most unaffected at dark night, when there being sun exposure, except automobile inner air
Middle formaldehyde, abnormal flavour material decompose its formaldehyde caught, gas with foreign flavor, formaldehyde in air, abnormal flavour in deaeration car
Material recovers again initial condition, can reuse.
