Abstract
The invention discloses abnormal flavour material and preparation method thereof in a kind of deicing case based on kieselguhr micropowder, belong to diatom technical field of nano material.Solve prior art removes the material of abnormal flavour in refrigerator and method 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.Abnormal flavour material in the deicing case of the present invention, is made up of the coating of label and cladding label, and 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 deicing case of the present invention, abnormal flavour material can not only remove the gas with foreign flavor in refrigerator, improves air quality in refrigerator, also has anion releasing, purifies air, the effect of adjusting air humidity, can be applicable to remove the gas with foreign flavor in refrigerator.
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
Abnormal flavour material and preparation method thereof in refrigerator.
Background technology
Refrigerator is a kind of product for civilian use making food or other article keep constant low temperature cold conditions, is widely used
Daily life in the mankind.Refrigerator is the limited container of low-temp storage article the most airtight, does not possesses
Ventilation performance, so during routine use, the abnormal smells from the patient in refrigerator is not easy to disperse.
In refrigerator, abnormal smells from the patient is mainly derived from the following aspects:
The original flavor of the food 1, deposited, garlicky garlicky；
2, food is spoiled, and this mainly has two aspects, and on the one hand refrigerator low temperature can only delay bacterial reproduction, no
Can suppress bacterial reproduction, so along with using the prolongation of refrigerator time, bacterial reproduction to a certain extent it is possible to
Cause food spoilage abnormal flavour；On the other hand food has life, there is respiratory activity, such as fruit vegetable
Enzyme is still contained after plucking, active, it is possible to decomposition nutrition matter carries out Repiration, the most also can synthesize
Cucumber, generally, saccharide or other organic substance oxidation Decomposition, generation two in fruit and vegerable during aerobic
Carbonoxide and moisture, and release amount of heat, during anoxia, in fruit and vegerable, saccharide can not aoxidize, and can only decompose generation
Ethanol, carbon dioxide, and release a small amount of heat, enough in order to obtain needed for vital movement during fruit and vegerable anoxia
Energy, be necessary for decomposing more nutrition, stay in fruit and vegerable because anaerobic respiration produces ethanol, outward appearance simultaneously
On see that fruit and vegerable change is little, but rotted inside fruit and vegerable.
3, taint of odour, is heat-forming food mixing taste, is again food original flavor spoiled mixing taste.Food original flavor, change
Taste and taint of odour three taste one just create the abnormal flavour of refrigerator.
Additionally, refrigerator peculiar smell also derives from the material of refrigerator, the material making refrigerator is mostly plastics, casing,
Though compressor, radiator are metalworks, but have been also coated with organic coating.When temperature is higher, plastics and painting
Layer has and more or less gives out some organic gas, so plastics taste can be produced, and temperature is the highest, gas
It is the fastest that taste dissipates.
In prior art, in removing refrigerator, the product of abnormal flavour mainly has bamboo charcoal or activated carbon.Bamboo charcoal and activated carbon
Being all porous carbon, bulk density is low, and specific surface area is big, so having stronger adsorption function, but bamboo charcoal,
Activated carbon does not possess functions such as stink, abnormal flavour degraded, decomposition.Absorption property easily reaches saturated, no
Deodorization, the function of clean taste can be kept muchly.The fruit such as Fructus Citri tangerinae, Fructus Ananadis comosi is also utilized to remove abnormal flavour in refrigerator
Method, but the absorption property of the fruit such as Fructus Citri tangerinae, Fructus Ananadis comosi is the most weak, mainly by discharge in atmosphere fragrance because of
Son covers the abnormal flavour in refrigerator.
Chinese patent discloses a kind of refrigerator deodorizer (publication number CN103007320A), and it includes activated carbon
Block and smell removal liquid, smell removal liquid composition be water, Flos Lonicerae extractive solution, Fructus Citri Limoniae extract, Flos Rosae Multiflorae extracting solution mixed
Compound, each composition is mixed by following percent volume to volume: water 50-75%, gold silver China extracting solution 8-12%, Fructus Citri Limoniae
Extracting solution 10-15%, Flos Rosae Multiflorae extracting solution 10-20%.Although abnormal flavour in removing refrigerator can be played one by this eliminating smell agent
Being set for use, but purification efficiency is the highest, clean-up effect persistency is low, will not anion releasing, moisture absorption, put
Moist difference, it is impossible to reuse.And the price of Flos Lonicerae extractive solution, Fructus Citri Limoniae extract and Flos Rosae Multiflorae extracting solution is inclined
Height, the product price obtained is higher.

The nano titanium oxide of titanium oxide/diatomite composite photocatalytic material area load is nanometer particle, therefore light swashs
Sending out the electronics produced and hole can be quickly from vivo migration to surface, hole is strong oxidizer, can will inhale
The hydroxyl and the water that are attached to nano titanium oxide surface are oxidized to OH；And conduction band electron is strong reductant, inhaled
It is attached to the dissolved oxygen capture on nano titanium oxide surface and is formedPartChain reaction can be continued through
Generate OH.Generate OH andThere is stronger oxidisability, it is documented, nano titanium oxide
The OH free radical that light-catalyzed reaction generates has the reaction energy of 402.8MJ/mol, each higher than organic compound
Class 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 andCan attack the c h bond of gas with foreign flavor, H atom active with it produces the most certainly
By base, excite chain reaction, finally make gas with foreign flavor be decomposed into harmless tasteless substance.
Abnormal flavour material in the deicing case of the present invention, is placed in refrigerator, it is possible to persistently catch gas with foreign flavor, i.e.
Being the most unaffected at dark night, when there being sun exposure, in deicing case, abnormal flavour material decomposes the different of its seizure
Taste gas, in deicing case, abnormal flavour material recovers again initial condition, can reuse.
