Description
Technical field
The present invention relates to a kind of hydroscopic high-molecular resin, more particularly to a kind of diaper hydroscopic high-molecular resin and its system
Preparation Method.
Background technology
Hydroscopic high-molecular resin is one kind with certain degree of cross linking, macromolecule not soluble in water, with high-water expansion
Compound, containing substantial amounts of hydrophilic radical and unique three-dimensional space network structure, there is very strong water suction, water holding capacity, energy
The moisture of even thousands of times of hundreds times of enough absorptance itself weight, and the moisture absorbed even if will not also overflow at elevated pressures
Go out, therefore be the important ring in diaper composition material.Lacked existing for hydroscopic high-molecular resin used in existing diaper
It is that water imbibition is not high enough to fall into, not environmentally friendly enough, and harmful effect is generated to environment.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of diaper hydroscopic high-molecular resin and preparation method thereof, inhales
It is water-based fine and more environmentally friendly, it is environmentally friendly.
In order to solve the above technical problems, the technical scheme is that：
A kind of diaper hydroscopic high-molecular resin, its parts by weight composition include：100~300 parts of acrylic acid, crosslinking agent 0.01~
0.03 part, 1.5~5 parts of initiator, 80~230 parts of sodium hydroxide, 7~20 parts of sea-tangle, 20~60 parts of acrylamide, reinforcing agent 10
~20 parts；Wherein, the sea-tangle is commercially available sea-tangle, and by attrition grinding to 100 mesh.
Preferably, crosslinking agent of the present invention is N, N- methylene-bisacrylamides.
Preferably, initiator of the present invention is the mixture of potassium peroxydisulfate and sodium sulfite.
Preferably, reinforcing agent of the present invention is methylene-succinic acid.
A kind of preparation method of diaper hydroscopic high-molecular resin and preparation method thereof, comprises the following steps：
(1) adding sodium hydroxide in acrylic acid by formula ratio makes its neutralization；
(2) acrylamide and the acrylic acid solution after neutralizing are configured to the aqueous solution, add sea-tangle and be dispersed with stirring, add crosslinking
Agent, initiator, reinforcing agent, stir, and polymerisation 5 hours, obtain polymer at 70 DEG C；
(3) by polymer after being granulated, dry, crush, obtained diaper hydroscopic high-molecular resin.
Therefore compared with prior art, the invention has the advantages that：
Sea-tangle as primary raw material is renewable resource, therefore more environmentally friendly, more friendly to environment, and sea-tangle can be with third
Acrylamide fully polymerize, and can effectively improve the water absorbent rate of resin, reach as high as 175.28g/g.
