Abstract
The invention discloses a kind of high-moisture-retention paper aid and preparation method thereof, this high-moisture-retention paper aid is made up of the component comprising following weight portion: Sodium Polyacrylate 50-80 part, cyclodextrin 30-55 part, stearine 10-15 part, silica 5-10 part, crosslinking agent 2-5 part, hydrogen peroxide 1 part and NaOH 0.5-1 part.The material that the present invention obtains not only has good water retention property, also has certain sterilization, bactericidal action, can be used for manufacturing paper nappy.
Description
Technical field
The invention belongs to pulp technology for making paper, particularly a kind of high-moisture-retention paper aid and preparation method thereof.
Background technology
Sodium Polyacrylate is a kind of containing strongly hydrophilic group, there is the functional high molecule material of certain degree of cross linking, it is a kind of high hydroscopic resin, due to the functional group containing a large amount of carboxyl, hydroxyl, amide groups and ether in its molecule, therefore its water sorption carries out mainly through weak chemical bonding.
Super absorbent resin can absorb the moisture of own wt hundred times usually, its rate of water absorption except and outside the Pass composition has, also relevant with the form of resin, the surface area of goods is larger, and water absorption rate is larger.
Sodium Polyacrylate molecular structure is cross-linked, and the moisture that molecular network absorbs can not be extruded with simple physical method, still can have good water-retaining property under elevated pressure.And due in polyacrylic acid sodium molecule containing carbonyl functional group, can the foul smell of adsorb ammonia, and have certain thickening effect.
Summary of the invention
For above-mentioned demand, the object of the present invention is to provide a kind of high-moisture-retention paper aid and preparation method thereof, obtained high-moisture-retention paper aid has good water retention property, and has certain sterilization, bactericidal action, can be used for manufacturing paper nappy.
Object of the present invention can be achieved through the following technical solutions:
A kind of high-moisture-retention paper aid, be made up of the component comprising following weight portion:
Sodium Polyacrylate 50-80 part,
Cyclodextrin 30-55 part,
Stearine 10-15 part,
Silica 5-10 part,
Crosslinking agent 2-5 part,
Hydrogen peroxide 1 part,
NaOH 0.5-1 part.
Described crosslinking agent is polyethylene glycol diglycidyl ester.
Described silica is nano particle, and its diameter is 200-300 nanometer.
A preparation method for high-moisture-retention paper aid, the method comprises the following steps:
By Sodium Polyacrylate 50-80 part, cyclodextrin 30-55 part, stearine 10-15 part, crosslinking agent 2-5 part and NaOH 0.5-1 part, in nitrogen atmosphere, under airtight pressurized conditions, 2-5 hour is stirred at 40-50 DEG C, after reaction terminates, add silica 5-10 part and hydrogen peroxide 1 part, stir, obtain high-moisture-retention paper aid.
The pressure of described airtight pressurization is 2-5MPa.
beneficial effect:
(1) the present invention uses Sodium Polyacrylate, cyclodextrin and stearine as the main raw material of water retention agent; the product of the mixing of these three kinds of materials has good protectiveness; cyclodextrin is also polyhydroxy macromolecular material; have good water suction and water retention property, adding of stearine makes the compatibility of each component in whole system and effect all have significant improvement.
(2) the present invention adds silica and makes this high water-based paper auxiliary agent have good moisture absorption and greasy property, pro-skin more.Adding of crosslinking agent makes the degree of cross linking of each component in whole system increase, thus makes Water-saving effect better.
(3) hydrogen peroxide has sterilization and bactericidal action, makes this high water-based paper auxiliary agent have corresponding sterilization and disinfective action while having efficient water-retaining property.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is further illustrated.
The detection method of product water absorption rate, take the dry paper of 5g containing the high-moisture-retention paper aid (mass percent that high-moisture-retention paper aid accounts for dry paper is 5%) of embodiment 1-3, add deionized water, stir upper cover on bonnet, place after 30 minutes, 20 object mesh screens drain the water, claim before and after paper of poor quality, be water absorption.
Embodiment 1
By Sodium Polyacrylate 50kg, cyclodextrin 30kg, stearine 10kg, polyethylene glycol diglycidyl ester 2kg and NaOH 0.5kg, in nitrogen atmosphere, 2Mpa, to stir 2 hours at 50 DEG C, after reaction terminates, add silica 5kg and hydrogen peroxide 1kg that diameter is 200 nanometers, stir, obtain high-moisture-retention paper aid.
The water absorption the performance test results of obtained high-moisture-retention paper aid is as shown in table 1.
Embodiment 2
By Sodium Polyacrylate 60kg, cyclodextrin 55kg, stearine 15kg, polyethylene glycol diglycidyl ester 3kg and NaOH 1kg, in nitrogen atmosphere, 3Mpa, to stir 5 hours at 40 DEG C, after reaction terminates, add silica 1 0kg and hydrogen peroxide 1kg that diameter is 300 nanometers, stir, obtain high-moisture-retention paper aid.
The water absorption the performance test results of obtained high-moisture-retention paper aid is as shown in table 1.
Embodiment 3
By Sodium Polyacrylate 80kg, cyclodextrin 45kg, stearine 10kg, polyethylene glycol diglycidyl ester 5kg and NaOH 0.5kg, in nitrogen atmosphere, 5Mpa, to stir 5 hours at 40 DEG C, after reaction terminates, add silica 6kg and hydrogen peroxide 1kg that diameter is 300 nanometers, stir, obtain high-moisture-retention paper aid.
The water absorption the performance test results of obtained high-moisture-retention paper aid is as shown in table 1.
Table 1
| Test event | Embodiment 1 | Embodiment 2 | Embodiment 3 |
| Water absorption (g) | 120 | 132 | 138 |
The paper using high-moisture-retention paper aid of the present invention to obtain as can be seen from Table 1 has good water imbibition, water absorption is more than 20 times of its paper weight, and along with adding the increase of the amount of crosslinking agent in reaction, the crosslinking points of this reaction is also more, and water imbibition is also better.
The invention is not restricted to above-described embodiment, those skilled in the art, according to announcement of the present invention, do not depart from improvement that scope makes and amendment all should within protection scope of the present invention.
