Description
Technical field
The invention belongs to new material technology field, a kind of nucleocapsid water lock material and its preparation method and application.
Background technology
High hydroscopic resin (Super Absorbent Polymer, abbreviation SAP) is a kind of suction of invention the 1960s
Water high polymer material, its primary raw material used are starch, but due to poor performance and unstable, are not valued by the people always.With
21 century rapid development of economy and the raising of people's living standard, the synthetic technology of SAP materials and application are sent out rapidly
Exhibition, raw material have been changed to acrylic acid by starch.It is developed so far, polyacrylate type high water absorption resin is that current research and production are most
A kind of synthesizing super absorbent resin, this kind of product water absorbent rate is higher, and up to more than thousand times, performance is relatively stable, thus obtains
Extensive use.
However, the super absorbent resin fat prod that acrylic acid is synthesized for main material is used at present, after generally existing water suction, by
Illumination facilitation water and cause moisture content can not locking the defects of；And the complexity of recycling design, dispersant in preparation process be present
Process.
The content of the invention
In order to solve the above problems, an object of the present invention is that the water-based energy of light shineization and water can be improved by providing one kind
The nucleocapsid water lock material of part Locking property.The present invention, by the protection of microballoon shell, is made using core-shell type water suction microballoon is prepared
Product has the water-based energy of excellent light shineization, greatly improves the moisture content Locking property after its saturation that absorbs water.
The second object of the present invention is the preparation method for providing the nucleocapsid water lock material, and this method can effectively control lock
The outer casing thickness of water micro-sphere material, so as to control the light shineization after material water suction water-based and water lock performance.
The present invention is achieved through the following technical solutions：
A kind of nucleocapsid water lock material, the particle diameter of the nucleocapsid water lock material is 80~160 μm, and housing is that thickness is 10~50
μm Calcium alginate film；The nucleome of the nucleocapsid water lock material is the mixture of anionic monomer and non-ionic monomer, in mass ratio
Calculate, anionic monomer：Non-ionic monomer is 2~4: 1.Wherein described anionic monomer is acrylic acid and/or methacrylic acid,
The non-ionic monomer is acrylamide and/or hydroxy-ethyl acrylate.Water lock material microspherulite diameter is excessive, and absorption speed is low, grain
Footpath is too small, the water conservation being unfavorable under pressure；For microballoon outer casing thickness, the usual blocked up influence absorption speed of shell membrane, shell membrane crosses book,
The water-based energy of protection illuminationization is not had, it is 10~50 μm, more preferably 15~25 μm that the present invention, which controls microballoon shell thickness,.
The method for preparing the nucleocapsid water lock material, it is described to comprise the steps of：
(1), first anionic monomer is added in deionized water, neutralized under normal temperature with sodium hydroxide solution, control neutralizes
25~30 DEG C of reaction temperature, it is 55~75% to control degree of neutralization, i.e. the mol ratio of acrylic or methacrylic acid and sodium hydroxide
For 100: 55~75, neutralizer is obtained；Then non-ionic monomer is added in neutralizer, the dosage of non-ionic monomer is neutralizer
The 1~10% of quality, obtain reaction solution A；It is anionic monomer: non-ionic monomer=2~4: 1 to control monomer mass.
(2) sodium alginate 1~3%, the crosslinking agent of relative response liquid A mass ratioes, are sequentially added in above-mentioned reaction solution A
0.25~1%, initiator 0.01~0.5% and pore-foaming agent 5~20%, obtain reaction solution B；
(3) dimethicone for, taking viscosity to be 50~100mPas is placed in reactor, then adds mass percent
For 5~15% calcium chloride solution, reaction medium is made, the reaction medium is the multiphase liquid layer being made up of water layer and oil reservoir；
(4), after the profit of reaction medium in (3) is mutually layered, heating oil phase instills reaction solution B, preferably to 60~80 DEG C
The reaction solution B of atomization will be instilled；
(5) after, reaction terminates, washing, desciccate, the porous nucleocapsid water lock material of pearl is obtained；The drying
Temperature is 80~130 DEG C, and drying time is 2~10h.
Wherein, reaction medium is divided into the multiphase liquid layer of water layer and oil reservoir in described (3), and upper strata is that water layer calcium chloride is water-soluble
Liquid, lower floor are oil reservoir dimethicone.To ensure that microballoon shell curing reaction is abundant, upper strata aqueous phase height of liquid layer should be greater than 5cm.
Reaction drop initially enters aqueous layer (upper strata), and the alginic acid contained by reaction solution sends cross-linking reaction with calcium chloride and solidified immediately
Spherical shell is formed, after microballoon is lowered into oil reservoir (lower floor) by gravity, oil phase can prevent the adhesion between spherical shell, so as to there is abundance
Time makes the reaction solution transmission polymerisation inside microballoon solidify and form water uptake core material.Reaction drop is introduced into aqueous layer, shape
Into solidification shell, enter oil phase after forming microballoon state particle, under oil phase peptizaiton and insulation effect, be enclosed in anti-in shell
Liquid is answered to continue to react.
It is preferred that the crosslinking agent is polynary pi-allyl, diolefin crosslinking agent or both compound.
It is preferred that the polynary allyl based cross-linker is allylation starch, allylation cellulose, tetraallyl epoxide
Ethane；Diolefin crosslinking agent is N, N '-methylene-bisacrylamide.
It is preferred that the initiator is azo-initiator, persulfuric acid salt initiator or both compound, wherein compounding
In thing, if compound, the control of its mass ratio is azo-initiator: persulfuric acid salt initiator is 3~5: 1.It is it is preferred that even
Nitrogen class is the isobutyl imidazole hydrochloride of azo two, and persulfate is potassium peroxydisulfate or/and ammonium persulfate.
It is preferred that the pore-foaming agent is one in sodium acid carbonate, saleratus, carbamide peroxide, urea, ethanol, acetone
Kind or several mixtures.It is preferred that mix compound, can pore-foaming agent to be summarized as three class a be one kind in sodium acid carbonate, saleratus
