Abstract

The invention provides a method for preparing a composite nanometer hydrogel precursor. An acrylamide lattice reagent and an ammonium persulfate initiator are stirred for 30 min, a set quantity of a saccharose carbon source is added, the molar ratio of carbon to aluminum atoms is 6, and a precursor mixing solution is obtained after stirring is performed at low temperature for 1 h. An ammonia solution with the concentration ratio being 1:2 is titrated into the mixing solution at the dripping speed of 3-5 ml/min, and continuous stirring is performed for 2 h after titration is finished. After stirring is performed, polymerization is performed at the temperature of 65 DEG C to obtain the composite nanometer hydrogel precursor. The obtained hydrogel is directly placed into a drying oven to be dried, and the precursor is obtained after drying is performed. Saccharose is adopted as a carbon source for preparing the hydrogel precursor, it is ensured that the precursor can be evenly dispersed, the defect that layering is caused when activated carbon is used as a carbon source is overcome, the obtained precursor is good in using performance, and the method is suitable for preparing the hydrogel precursor.

Description

Prepare the method for composite Nano hydrogel precursor
Technical field
What the present invention proposed is chemical field process control method, specifically prepares the method for composite Nano hydrogel precursor.
Background technology
In chemical industry, widely use hydrogel at present, and use hydrogel to participate in chemical reaction as presoma, usually in hydrogel, add gac carbon source, and the presoma made exists demixing phenomenon, affect result of use.
Summary of the invention
In order to overcome existing hydrogel precursor demixing phenomenon, the present invention proposes the method preparing composite Nano hydrogel precursor.The method using sucrose as carbon source, prepares presoma by composite aquogel.Solve the technical problem that composite aquogel presoma carbon source selects to ensure presoma uniformity coefficient.
The scheme that technical solution problem of the present invention adopts is:
Acrylamide lattice reagent and ammonium persulfate initiator, after stirring 30min, add the sucrose carbon source of set amount, and carbon and aluminium atomic molar, than being C/Al=6, after low temperature 1h, obtain presoma mixed solution.Be ammonia soln the dripping in this mixed solution of speed instillation with 3 ~ 5ml/min of 1:2 by concentration ratio, titration terminates rear continuation and stirs 2h.Stir rear 65 DEG C of polymerizations and obtain composite Nano hydrogel.The hydrogel of gained is directly put into baking oven dry, after oven dry, obtain presoma.
Positively effect, the present invention adopts sucrose to be carbon source, prepares hydrogel precursor, can ensure that presoma is dispersed, and overcome the defect using gac as carbon source layering, prepared presoma use properties is excellent.The suitable method application as preparing hydrogel precursor.
Accompanying drawing explanation
Fig. 1 is present invention process procedure chart.
Embodiment
According to the figure, in the aluminum nitrate solution of the 0.3mol/l of frozen water temperature control, add acrylamide monomer, methylene radical acrylamide lattice reagent and ammonium persulfate initiator, after stirring 30min, add the sucrose carbon source of set amount, carbon is C/Al=6 with aluminium atomic molar ratio, after low temperature 1h, obtain presoma mixed solution, be ammonia soln the dripping in this mixed solution of speed instillation with 3 ~ 5ml/min of 1:2 by concentration ratio, titration terminates rear continuation and stirs 2h, stirs rear 65 DEG C of polymerizations and obtains composite Nano hydrogel.The hydrogel of gained is directly put into baking oven dry, after oven dry, obtain presoma.
Feature:
In presoma, take ammoniacal liquor as the condition of precipitation agent, setting network proportioning, carbon al mole ratio is 6, is that carbon source synthesizes presoma respectively with sucrose.Take sucrose as carbon source, aluminium and carbon mix.
Sucrose carbon atom can be evenly distributed in the three-dimensional net structure that aluminum oxide formed.Contained element is Al element, O element, C element, N element, and carbon and aluminium atom are evenly distributed.
Experiment proves:
Adopt sucrose or gac to be carbon source in experiment respectively, adopt polymer-network gel process synthesis presoma.It is carbon source that research finds with sucrose, and aluminium source and carbon mix; And be carbon source with gac, there is obvious demixing phenomenon in AlN presoma.The control of this composite Nano hydrogel techniques solves the mixing non-uniform phenomenon that traditional method prepares synthetics.
