Description
Technical field
The present invention relates to the method that starch spray drying prepares capsule-type papermaking filler.
Background technology
At present, the open a kind of starch spray drying of China Patent No.: CN201410054001.4 is prepared capsule-type papermaking and is filled out
The method of material, comprises the steps: to weigh a certain amount of starch, with water-dispersible uniformly after carry out gelatinizing process.Separately weigh a certain amount of
Papermaking filler carries out, after water-dispersible, the process that homogenizes.Carry out, after papermaking filler and gelatinized starch are mixed, the process that homogenizes again.
Finally the mixture of papermaking filler and gelatinized starch is spray-dried, papermaking filler particle surface one layer of stratum granulosum of parcel,
Starch parcel capsule-type papermaking filler.The method has that technique is simple, low cost, easily operation, modified effect are obvious
Etc. feature.Compare unmodified papermaking filler, prepare gained capsule-type papermaking filler and improving the amount of being filled with of paper, save plant fine
While dimension raw material, the physical strength performance of filled paper can be significantly improved, and improve the quality of final paper product.But this shape
Formula is more single, and the function of filler, performance are the most single, after being applied to paper, it is impossible to embody function with a greater variety again.
Summary of the invention
Therefore, for above-mentioned problem, the present invention proposes a kind of simple in construction, can be greatly increased carrier performance and function
The starch spray drying method of preparing capsule-type papermaking filler.
For achieving the above object, present invention employs techniques below scheme: a kind of starch spray drying is prepared capsule-type and made
The method of paper wadding, comprises the following steps:
The first step, starch gelatinization, weigh a certain amount of starch, add appropriate amount of deionized water, be configured to starch suspension, stir
Gelatinizing process is carried out after dispersion；
Second step, methylcellulose dissolves, weighs a certain amount of methylcellulose, be dissolved in the water, and after stirring, cooling obtains first
Base cellulose slurry；
3rd step, the homogeneous dispersion of filler, weigh a certain amount of papermaking filler, add appropriate amount of deionized water, be configured to filler suspension,
Then add appropriate Alumen to be stirred, be passed through a small amount of gas of feeding or fluid during stirring, then be uniformly dispersed with homogenizer；
4th step, mixes, through homogeneous with methylcellulose slurry, the filler suspension of step 4 gained respectively again by step 2
Machine is uniformly dispersed, and then stands appropriate time；
5th step, mixes with the suspension of step 4 gained again by the starch suspension of step one gained, disperses through homogenizer
Uniformly, spray dryer spray drying treatment is then utilized.
Further, in step 2, first heat water to 70 DEG C, and step up water temperature until 75 DEG C, in this process
In be gradually added into methylcellulose.
Further, one during described starch is corn starch, potato starch, carboxymethyl starch, Oxytarch or
Several.
Further, the mass percentage concentration of described starch suspension is 6～7%, and gelatinization point is 90～95 DEG C, gelatinizing
Time is 75～85min.
Further, one or more during described papermaking filler is calcium carbonate, Pulvis Talci, Kaolin.
Further, the mass ratio between starch, methylcellulose, papermaking filler is 1:1:5.
By using preceding solution, the invention has the beneficial effects as follows: this starch spray drying prepares capsule-type papermaking
The method of filler, is in China Patent No.: the improvement made on CN201410054001.4 basis, by increasing Methyl cellulose
Element forms another road cladding wall, and makes filler self formation space tie by the way of increasing Alumen and being passed through gas or fluid
Structure, thus forming the infilling structure of two-layer cladding, so that the performance of filler is greatly increased, and the gas being passed through
Or fluid can be suitable make change, as utilized essence or coloring matter, can after filler invests paper, paper use
Time other effect can be had to occur；Further, first heat water to 70 DEG C, and step up water temperature until 75 DEG C,
Being gradually added into methylcellulose during this, also stepping up water temperature during being gradually added methylcellulose is in order to more
Realize well the dissolving of methylcellulose, and it is so that methylcellulose keeps relatively after being melted into water that limit temperature is 75 DEG C
Good form.
Detailed description of the invention
In conjunction with the present invention is further described with detailed description of the invention.
The present embodiment provides a kind of method that starch spray drying prepares capsule-type papermaking filler, comprises the following steps:
The first step, starch gelatinization, weigh a certain amount of starch, add appropriate amount of deionized water, be configured to starch suspension, stir
Gelatinizing process is carried out after dispersion；
Second step, methylcellulose dissolves, weighs a certain amount of methylcellulose, first heat water to 70 DEG C, and progressively carry
High water temperature until 75 DEG C, is gradually added into methylcellulose in the process, until methylcellulose is fully dissolved in water, and stirring
Rear cooling obtains methylcellulose slurry；
3rd step, the homogeneous dispersion of filler, weigh a certain amount of papermaking filler, add appropriate amount of deionized water, be configured to filler suspension,
Then add appropriate Alumen to be stirred, be passed through a small amount of gas of feeding or fluid during stirring, then be uniformly dispersed with homogenizer；
4th step, mixes, through homogeneous with methylcellulose slurry, the filler suspension of step 4 gained respectively again by step 2
Machine is uniformly dispersed, and then stands appropriate time；
5th step, mixes with the suspension of step 4 gained again by the starch suspension of step one gained, disperses through homogenizer
Uniformly, spray dryer spray drying treatment is then utilized.
Above-mentioned starch is one or more in corn starch, potato starch, carboxymethyl starch, Oxytarch；Above-mentioned
The mass percentage concentration of described starch suspension can be any value between 6% or 7% or 6～7%, and gelatinization point is 90 DEG C
Or the arbitrary temperature between 95 DEG C or 90～95 DEG C, gelatinization time is the arbitrary number between 75min or 85min or 75～85min
Value；Above-mentioned papermaking filler is one or more in calcium carbonate, Pulvis Talci, Kaolin；Above-mentioned starch, methylcellulose, papermaking
Mass ratio between filler is 1:1:5.
This starch spray drying prepares the method for capsule-type papermaking filler, is in China Patent No.:
The improvement made on CN201410054001.4 basis, forms another road cladding wall by increasing methylcellulose, and passes through
Increasing Alumen makes filler self form gap structure with the mode being passed through gas or fluid, thus is forming the sky of two-layer cladding
Gap filling-material structure, so that the performance of filler is greatly increased, and the gas being passed through or fluid can be suitable makes change,
As utilized essence or coloring matter, other effect after filler invests paper, can be had to occur when paper uses；Enter
One step, first heat water to 70 DEG C, and step up water temperature until 75 DEG C, be gradually added into Methyl cellulose in the process
Element, also stepping up water temperature during being gradually added methylcellulose is in order to methylcellulose molten is better achieved
Solve, and it is so that methylcellulose keeps preferable form after being melted into water that limit temperature is 75 DEG C.
Although specifically showing and describe the present invention in conjunction with preferred embodiment, but those skilled in the art should be bright
In vain, in the spirit and scope of the present invention limited without departing from appended claims, in the form and details can be right
The present invention makes a variety of changes, and is protection scope of the present invention.
