Description
Technical field
The present invention relates to a kind of preparation methods with polyacrylic acid and organic quick lime composite drying agent, belong to desiccant system
Standby 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.
Polyacrylic acid series product is nontoxic, nonirritant, mildly bitter flavor, have good water solubility, and with many organic matters
Component has good intermiscibility.As in the recirculating cooling water systems such as power plant, chemical plant, chemical fertilizer factory, oil plant and air-conditioning system
Dirt dispersion agent, have extremely wide application in many industries.

As an improvement the mass ratio of acrylic acid described in step 1) and isopropanol is 1:1.
As an improvement organic quick lime surface aggregate has polyacrylic acid, the average molecular of the polyacrylic acid
Amount is between 100000-2000000.
A kind of preparation method with polyacrylic acid and organic quick lime composite drying agent provided by the invention, it is using as follows
Step:
1) mass fraction is pressed, 100 parts of lump limes, 9 parts of acrylic acid and isopropyl alcohol mixture are taken, by 100 parts of bulks
Quick lime is crushed, and ground 170 mesh is placed in vacuum planetary ball mill tank, and vacuum planetary ball mill tank is vacuumized, is filled with
9 parts of acrylic acid and isopropyl alcohol mixture is added in nitrogen, in vacuum planetary ball mill tank under the conditions of 45 DEG C, with 1500r/min
Then grinding rate, griding reaction 1.3h at the uniform velocity reduce grinding rate, until stopping grinding completely, keep the quiet reaction of vacuum
0.8h 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 the mass ratio of acrylic acid described in step 1) and isopropanol is 1:1, the institute that step 2) obtains
Stating organic quick lime surface aggregate has polyacrylic acid, and the relative molecular weight of the polyacrylic acid is 1050000.
Profitable effect of the invention: preparation process is filled with sufficient nitrogen, and the desiccant prepared is with high purity, particle is equal
It is even；Moisture absorption is good, reacts and mitigates after water suction, and safety is good, and process is simple, at low cost, no coupling product production, environmental protection and energy saving,
It is suitble to large-scale production；Polyacrylic acid itself has good wash water, prevent the moisture in air is from directly by quick lime
It absorbs, polyacrylic acid absorbs moisture first, is then passed to quick lime, avoids quick lime and directly quickly absorb moisture, occurs
Vigorous reaction generates a large amount of heat, causes security risk；Polyacrylic acid non-toxic and safe itself is reliable, and tensile strength is big, to raw stone
Ash explodes, and has protective action.
