Description
Technical field
The present invention relates to a kind of preparation methods with polyethylene oxide and organic quick lime composite drying agent, belong to desiccant
Preparation field.
Background technique
Quick lime is the common desiccant that vapor is removed using chemical absorption method, is also used for steel, pesticide, medicine, does
Drying prescription, process hides and dehydration of alcohol etc..Especially suitable for the local and special products such as dilated food, mushroom, agaric and instrument, medicine,
The product of the industries such as dress ornament, electronics telecommunication, leather, weaving.It usually is heated to 500-600 DEG C by substance calciferous, makes it
It is decomposed into calcium oxide and carbon dioxide.Shape is white, unformed, is widely used in desiccant, typically contains in quick lime
Excessive fire lime and the lime that has not been cooked or heated long enough, excessive fire lime structure is closely knit, and surface often coats one layer of fusant, dissolves very slowly, in the lime that has not been cooked or heated long enough
Calcium carbonate do not decompose completely, when use, lacks cohesive force.Quick lime can be chemically reacted with water, will be heated to surpass at once
More 300 DEG C of high temperature.Since fierce chemical reaction (hydration reaction) can occur for quick lime and water, calcium hydroxide is generated, is had
Extremely strong water imbibition can be used as a kind of fabulous desiccant raw material.But calcium oxide react when can sharply heat release, reaction swash
It is strong, uncontrollability is shown, fire occurs when can cause explosion and storage often.
The polyethylene oxide of super high molecular weight, also known as polyoxyethylene, have more hydroxyl, good water solubility, have compared with
Good hygroscopicity, can carry out esterification, be also easy to electron accepting groups association or autoxidation.Polyethylene oxide can have more
Phase catalytic polymerization, catalyst are carbonate, alkaline earth oxide, zinc alkyl, hydrate of iron halide etc..

Then griding reaction 1-1.5h at the uniform velocity reduces grinding rate, until stopping grinding completely, keep the quiet reaction 0.5-1h of vacuum, obtain
Obtain product A；
2) the product A for taking step 1) to obtain in the baking oven under the conditions of being placed in 105-110 DEG C, dries 1-2h, obtains 3-6mm
The organic quick lime composite drying agent of graininess.
As an improvement organic quick lime surface aggregate has a polyethylene oxide, the polyethylene oxide it is opposite
Molecular weight is between 100000-2000000.
A kind of preparation method with polyethylene oxide and organic quick lime composite drying agent provided by the invention, it is using such as
Lower step:
1) mass fraction to be pressed, 100 parts of lump limes are taken, 100 parts of lump limes are crushed by 9 parts of ethylene oxide,
Ground 170 mesh is placed in vacuum planetary ball mill tank, and vacuum planetary ball mill tank is vacuumized, nitrogen is filled with, and 9 parts of rings are added
Oxidative ethane, in vacuum planetary ball mill tank under the conditions of 45 DEG C, with 1500r/min grinding rate, griding reaction 1.3h is then even
Speed reduces grinding rate, until stopping grinding completely, keeps the quiet reaction 0.8h of vacuum, obtains product A；
2) the product A for taking step 1) to obtain in the baking oven under the conditions of being placed in 107 DEG C, dries 1.5h, obtains of 4.5mm
Granular organic quick lime composite drying agent.
As an improvement organic quick lime surface aggregate has ethylene oxide, the opposite of the polyethylene oxide is divided
Son amount is 1050000.
Profitable effect of the invention: organic quick lime composite drying agent moisture absorption prepared by the present invention is good, water suction
Reaction mitigates afterwards, and safety is good, and preparation process is simple, at low cost, and no coupling product production, environmental protection and energy saving are suitble to large-scale production；
Polyethylene oxide itself has good wash water, prevent the moisture in air is by quick lime from directly being absorbed, polycyclic oxygen second
Alkane absorbs moisture first, is then passed to quick lime, avoids quick lime and directly quickly absorbs moisture, vigorous reaction occurs, produces
Raw a large amount of heat, causes security risk；Polyethylene oxide tensile strength itself is big, explodes to quick lime, and there is protection to make
With.
