Description
Technical field
The invention belongs to deodorant technical fields, and in particular to a kind of preparation method of deodorant for refrigerator.
Background technique
Domestic refrigerator is indispensable electric equipment products in people's life, and almost there is refrigerator in every household.And when what refrigerator was filled in expires
Full, various veterinary antibiotics, meat etc. are placed in refrigerator for a long time can generate various peculiar smell, this both influences health, also destroys food
The deliciousness of product, therefore people are higher and higher to the cry of deodorant for refregerator.
The foul gas generated in refrigerator mainly has many kinds of substance such as methyl mercaptan, ethyl mercaptan, trimethylamine, ammonia, hydrogen sulfide.Needle
To these foul gas, many companies develop a variety of deodorant for refrigerator.Currently, in the market it is main sell with active carbon, zeolite,
The inorganic porous materials such as medical stone and sepiolite are the physisorption type deodorant for refrigerator of raw material, although these deodorant can be
Play deodorization in short time, but there is also easy saturation, adsorption rate is slow, have a single function and deodorizing effect is general etc. lacks
Point.Although and chemisorption type deodorant for refrigerator have the advantages that by reaction eliminate malodor molecules, due to its be applied to ice
In case, temperature is low, needs suitable reaction condition, it is desirable that and it is high, it is rarely reported.There are also light to urge for the taste removal technology used in refrigerator
Change, however photocatalysis is lower to the degradation efficiency of stink also limits it and be widely applied.
Summary of the invention
The technical problems to be solved by the invention:, the problem of deodorizing effect difference slow for current deodorant for refrigerator adsorption rate, this
Invention provides a kind of preparation method of deodorant for refrigerator.
In order to solve the above technical problems, the present invention is using technical solution as described below:
A kind of preparation method of deodorant for refrigerator, the preparation method include the following steps:
(1) it takes luffa to be put into hydrogen peroxide to be impregnated, take out, wash, it is dry, pretreatment luffa is obtained, in parts by weight
Meter, takes 120~130 parts of water, 60~80 parts of dehydrated alcohols, 50~60 parts of pretreatment luffas, 30~35 parts of butyl titanates, 20
~23 parts of ethyl orthosilicates, 13~16 parts of additives, 8~13 parts of regulators, 4~7 parts of surfactants；
(2) dehydrated alcohol, butyl titanate and ethyl orthosilicate being uniformly mixed first, ultrasonic vibration is put into reactor, then
Pretreatment luffa, additive is added, is preheated at 40~45 DEG C, adds water, surfactant, stirs, stands；
(3) after standing, regulator is added, is warming up to 90~95 DEG C, carries out boosting to 1.3~1.5MPa using hydrogen,
2~4h is heated, cooling, discharging collects out material, material out is mixed with ammonium hydrogen carbonate 7:1~3 in mass ratio, obtains base
Body object；
(4) matrix object is put into extruder and is pressurizeed, be put into retort and carbonized, collect carbide, crushed, mistake
Sieve collects sieving particle to get deodorant for refrigerator.
The additive is polyvinyl acetate emulsion, ethylene glycol 3:2 in mass ratio is mixed.
The regulator is that P123, polyethylene glycol 6~9:5 in mass ratio are mixed.
The surfactant is dodecyl sodium sulfate, any one in neopelex.
The condition carbonized in the step (4) is to be heated up 200~300 DEG C with 15 DEG C/min, keeps the temperature 1~2h, then be warming up to
500~600 DEG C, carbonize 3~5h.
The present invention is compared with other methods, and advantageous effects are:
The present invention is using luffa as carrier, by luffa pore structure abundant, can there is preferable load and adsorptivity
Can, luffa is handled by hydrogen peroxide first, luffa surface impurity is on the one hand removed, on the other hand improves luffa
Surface-active, then mixed again with butyl titanate, ethyl orthosilicate, by by both substances to luffa inside
It is filled, makes internal void supported titanium, element silicon, and pass through in acid condition, with polyvinyl acetate emulsion, ethylene glycol
As additive, the agglomeration traits between substance can be effectively solved, while increasing the bond strength with luffa, add table
Face activating agent improves the water resistance on surface, then under the action of regulator, settles titanium therein, element silicon, finally
It is carbonized, the absorption property of luffa is improved by charing, while in the condition of high temperature, titanium, silicon ortho acid form mesoporous shape
Titanium, silicon crosslinked, are deposited on luffa surface, improve the rate of adsorption, and increase deodorizing effect.
