Description
Technical field
The invention discloses a kind of preparation methods of porous aquagel, belong to technical field of polymer materials.
Background technique
Hydrogel is a kind of hydrophily but high molecular polymer not soluble in water.It is flat that they can be swelling to rapidly one in water
Weighing apparatus volume and be still able to maintain its shape and three-dimensional space network structure, and be dehydrated deswelling under certain conditions, be a class set
Water suction, is sustained in one and the functional polymer material that quickly grows water conservation.Because its is unique, water conservation and bionical characteristic, water
Gel is widely used in the purposes of industry, agricultural, medicine and biological engineering material field hydrogel mainly by swelling rate, molten
The parameters such as swollen rate and mechanical strength characterize.Although the gel of conventional method synthesis can obtain higher swelling ratio, its is molten
Swollen dynamics is usually all relatively slow, is influenced by material selection and production technology, the swelling of hydrogel and deswelling time can
From several seconds to even a few days a few hours.In practical application, generally the swelling rate of hydrogel need to be improved by reducing size, this
Just hydrogel is significantly limited in the application of the fields of biomedicine such as medicine controlled releasing, transmission and organizational project.It is solidifying in order to get rid of
Limitation of the glue size to the swelling deswelling rate of hydrogel extends it and is needing quick response rate field, especially as
Use in terms of enviromental sensitive hydrogel, it is a kind of effective method in porous water that porous structure is introduced into hydrogel
In gel, the scale calibration for determining swelling time is pitch of holes rather than gel three-dimensional size.When diffusion path narrows down to enough
Short (capillary channel), and between hole be it is interconnected, the transfer rate of swelling solution will primarily depend upon capillary force, compared with
Its diffusion process in polymer network is much faster.Therefore, the swelling that porous structure can greatly improve hydrogel is moved back
Swelling rate.
And traditional porous aquagel there is also porosity is low, therefore how the not high problem of intensity makes porous aquagel
Playing better performance becomes the art one of the technical problems that are urgent to solve.
Summary of the invention
The present invention solves the technical problem of: low for traditional porous aquagel porosity, intensity is not high to be lacked
Point provides a kind of preparation method of porous aquagel.
In order to solve the above-mentioned technical problem, the technical scheme adopted by the invention is that:
A kind of preparation method of porous aquagel, specific preparation process is as follows:

~8 parts of emulsifiers, 8~10 parts of calcium carbonate, 2~3 parts of ammonium persulfates, 10~20 parts of modified additives, 8~10 parts composite foamed
Agent, 60~80 parts of water；
(2) acrylamide, drying oil, linoleic acid, emulsifier, calcium carbonate and water mixing will be pre-processed, ammonium persulfate is subsequently added into,
The reaction of nitrogen charging heating stirring is subsequently added into modified additive and composite foamable agent, and injection molding is stood, and demoulding obtains blank；
(3) blank is placed in ultrasonic immersing in hydrochloric acid, taken out, it is dry to get porous aquagel.
The preparation process of step (1) described modified additive are as follows: mix polyvinyl alcohol and water 1:30~1:50 in mass ratio
It closes, after standing swelling, 0.5~0.8 times of polyvinyl alcohol quality of gelatin is added in heating stirring dissolution, and stirring and dissolving is then added
The hydrochloric acid and 8~10 times of polyvinyl alcohol quality of glutaraldehyde solution that 8~10 times of polyvinyl alcohol quality are stirred to react, filtering, stripping and slicing,
Washing is dried in vacuo, and is crushed, is obtained modified additive.
Step (1) composite foamable agent be sodium bicarbonate and N, N'- methylene-bisacrylamide 1:1~1 in mass ratio:
2 mixed preparings form.
Step (2) the pretreatment acrylamide is with the acrylamide after acetone recrystallization.
Step (2) the nitrogen charging heating stirring reaction condition are as follows: the rate that is filled with of nitrogen is 100~120mL/min, temperature
It is 70~75 DEG C, revolving speed is 300~500r/min.
Step (1) drying oil is linseed oil, any one in tung oil or Chinese catalpa oil.
Step (1) emulsifier is neopelex, alkyl glycosides, any in Tween-80 or Si Pan -80
It is a kind of.
The beneficial effects of the present invention are:
(1) of the invention by adding modified additive and composite foamable agent, it is coagulated in modified gel additive containing sensitive to pH
Plastic structure, after being added in product, when near gelatin isoelectric point, gel can be with ring when deviateing isoelectric point in contraction state
The change of the pH in border and expand or shrink, in use, firstly, heated point of sodium bicarbonate in composite foamable agent
Solution, the gas and sodium carbonate of generation, the gas of generation play foaming effect, so that the porosity of system gets a promotion, secondly, raw
At sodium carbonate the pH of system is gradually increasing, carboxylic ions in gelatin are mutually exclusive with negative electrical charge of the same race, modified addition
Material expansion, the pressure for expanding generation refine the hole of the generation in system further, again, in heating reaction process
In, the gelatin in modified additive is melted by pyrolysis, so that the porosity of system is further promoted；
(2) present invention is by addition drying oil and linoleic acid, in use, due to the aliphatic long-chain structure of drying oil,
So that the shock resistance and flexibility of emulsion liquid membrane get a promotion in system, secondly, compared with drying oil, the Asia oil of homogenous quantities
Acid can provide more double bonds, and the unsaturated bond increasing proportion in system increases its crosslinking points, further improves product
Intensity.
