As a kind of improvement, step 1) described in acrylic acid and the mass ratio of isopropanol be 1:1.
Used as a kind of improvement, organic quick lime surface aggregate has polyacrylic acid, the polyacrylic average molecular
Amount is between 100000-2000000.
A kind of preparation method with polyacrylic acid and organic quick lime composite drying agent that the present invention is provided, it is using as follows
Step:
1) by mass fraction, 100 parts of lump limes, 9 parts of acrylic acid and isopropyl alcohol mixture are taken, it is block by 100 parts
Quick lime is crushed, ground 170 mesh sieve, is placed in vacuum planetary ball mill tank, and vacuum planetary ball mill tank evacuation is filled with
Nitrogen, adds 9 parts of acrylic acid and isopropyl alcohol mixture, in the 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) take step 1) the product A that obtains, in the baking oven being placed under the conditions of 107 DEG C, dry 1.5h, obtain 4.5mm
Granular organic quick lime composite drying agent.
As a kind of improvement, step 1) described in acrylic acid and the mass ratio of isopropanol be 1:1, step 2) institute that obtains
Stating organic quick lime surface aggregate has polyacrylic acid, and the polyacrylic relative molecular weight is 1050000.
The profitable effect of the present invention:Preparation process is filled with sufficient nitrogen, and the desiccant purity prepared is high, granule is equal
It is even;Moisture sorption effect is good, and reaction after water suction relaxes, and safety is good, and process is simple, low cost, no coupling product production, environmental protection and energy saving,
Suitable large-scale production;Polyacrylic acid itself has good wash water so that the moisture in air can not directly by quick lime
Absorb, polyacrylic acid absorbs moisture first, be then passed to quick lime, it is to avoid quick lime directly quickly absorbs moisture, occurs
Vigorous reaction, produces substantial amounts of heat, causes potential safety hazard;Polyacrylic acid non-toxic and safe reliability itself, tensile strength are big, to calculogenesis
There is blast in ash, with protective action.
