Description
Technical field
The present invention relates to a kind of with polyethylene glycol and the preparation method of organic quick lime composite drying agent, belong to drier system
Standby field.
Background technology
Quick lime is the conventional drier that vapor is removed using chemical absorption method, is also used for steel, agricultural chemicals, medicine, dry
Dehydration of drying prescription, process hides and alcohol etc..Be particularly well-suited to 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.500-600 DEG C generally is heated to by material calciferous, makes it
It is decomposed into calcium oxide and carbon dioxide.Profile is white, unformed, is widely used in drier, is typically contained in quick lime
Overdo lime and the lime that has not been cooked or heated long enough, and the lime structure that overdoes is closely knit, and surface often coats one layer of fused mass, dissolves very slowly, in the lime that has not been cooked or heated long enough
Calcium carbonate do not decompose completely, cohesive force is lacked when using.Quick lime can chemically react with water, will be heated to surpass at once
More 300 DEG C of high temperature.The chemical reaction (hydration reaction) of fierceness can occur due to quick lime and water, calcium hydroxide is generated, have
Extremely strong water imbibition, can be used as a kind of fabulous drier raw material.But calcium oxide react when can drastically heat release, its reaction swash
It is strong, uncontrollability is shown, blast can be triggered often and fire occurs when storing.
Polyethylene glycol product is nontoxic, nonirritant, mildly bitter flavor, with good water solubility, and with many organic matter components
There is good intermiscibility.They have excellent lubricity, moisture retention, dispersiveness, bonding agent, antistatic additive and softening agent etc.,
In the industries such as cosmetics, pharmacy, chemical fibre, rubber, plastics, papermaking, paint, plating, agricultural chemicals, intermetallic composite coating and food processing
There is extremely wide application.
The content of the invention
The present invention provide have prepare it is simple, use that safety, drying effect are good, be adapted to the technical characterstics such as large-scale production
A kind of preparation method preparation method with polyethylene glycol and organic quick lime composite drying agent.
A kind of preparation method with polyethylene glycol 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 are taken, 5-13 parts of ethylene glycol is broken 100 parts of lump limes

Enter 5-13 parts of ethylene glycol, in the vacuum planetary ball mill tank under the conditions of 40-50 DEG C, with 1000-2000r/min grinding rates, grind
Mill reaction 1-1.5h, then at the uniform velocity reduces grinding rate, until stopping grinding completely, keeps the quiet reaction 0.5-1h of vacuum, obtains
Product A；
2) take step 1) obtain product A, in the baking oven being placed under the conditions of 105-110 DEG C, dry 1-2h, obtain 3-6mm
The organic quick lime composite drying agent of graininess.
Improved as one kind, organic quick lime surface aggregate has polyethylene glycol, the average molecular of the polyethylene glycol
Amount is between 100000-2000000.
A kind of preparation method with polyethylene glycol 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 are taken, 100 parts of lump limes are crushed, ground by 9 parts of ethylene glycol
Honed 170 mesh sieve, is placed in vacuum planetary ball mill tank, and vacuum planetary ball mill tank is vacuumized, and is filled with nitrogen, adds 9 parts of second two
Alcohol, in the vacuum planetary ball mill tank under the conditions of 45 DEG C, with 1500r/min grinding rates, then griding reaction 1.3h at the uniform velocity drops
Low grinding rate, until stopping grinding completely, keeps the quiet reaction 0.8h of vacuum, obtains product A；
2) take step 1) obtain product A, 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 one kind improve, step 2) obtain described organic quick lime surface aggregate have polyethylene glycol, the poly- second two
The relative molecular weight of alcohol is 1050000.
Profitable effect of the invention：Organic quick lime composite drying agent moisture sorption effect prepared by the present invention is good, after water suction
Reaction relaxes, and security is good, and process is simple, low cost, and no coupling product production, environmental protection and energy saving are adapted to large-scale production；Poly- second two
Alcohol has good wash water in itself so that the moisture in air directly can not be absorbed by quick lime, and polyethylene glycol absorbs first
Moisture, be then passed to quick lime, it is to avoid quick lime directly quickly absorbs moisture, and vigorous reaction occurs, and produces substantial amounts of heat,
Cause potential safety hazard；Tensile strength is big in itself for polyethylene glycol, quick lime is exploded, with protective action.
