The liquid permeability, the water absorbing speed, the water retention property and the gel strength of the resin are obviously improved with the method under the condition of no obvious declination of the water absorbing capacity of the water absorbing resin of sodium polyacrylate. The resin can be used as a superior water absorbing material.
Description
Technical field
The present invention relates to the production field of absorption resin of sodium polyacrylate, especially a kind of method for modifying surface of absorption resin of sodium polyacrylate.
Background technology
The sodium polyacrylate water-absorbing resin, because its remarkable water-absorbent, successfully added in various paper and the fiber in order to the sanitary product of manufacturing property excellence for many years, as baby's nappy, sanitary towel etc., in all respects such as agricultural, industry, building, medicine, daily necessities, food, light industrys, be with a wide range of applications.
The method of producing water-absorbing resin is a lot, as: (1) synthetic water-absorbing resin, moisture absorption becomes tide easily in air, bonding agglomerating mutually, liquid permeability is poor, during suction, the chance water section becomes sticky, moisture is difficult to infiltration inwards, causes water absorbent rate, absorption speed to reduce significantly, has influenced the actual water absorbing properties of water-absorbing resin.(2) resin of producing with water solution polymerization process is convenient and swift, but after the water-absorbing resin of aqueous solution polymerization need carry out surface treatment, just can make it possess preferable performance, in order to obtain colory water-absorbing material, must adopt proper method, improves performance.But also there is not effective surface-treated method at present.
Summary of the invention
The object of the present invention is to provide a kind of method for modifying surface of absorption resin of sodium polyacrylate, under the situation that this method does not take place obviously to descend at the absorption resin of sodium polyacrylate water-retaining capacity, significantly improve liquid permeability, absorption speed, water-retentivity, the gel-strength of resin, obtain the water-absorbing material of Heat stability is good, high comprehensive performance.
Technical scheme of the present invention is: this kind method for modifying surface of absorption resin of sodium polyacrylate is characterized in that step is as follows:
1), preparation treatment solution A:
Select for use mixture one of any or two or more in methyl alcohol, ethanol, isopropylcarbinol, acetone, the pentanone as dispersion agent; Select for use dichloroisopropanol, epoxy chloropropane, glycerine, butyleneglycol, diglycidylether, bisphenol-A epoxy, ethylene glycol, 2-glycidyl or Resins, epoxy one of any as linking agent, DMP-30 is as crosslinking accelerator; Place Glass Containers to stir dispersion agent, linking agent, crosslinking accelerator, be mixed with treatment solution A;
2), preparation treatment solution B:
Place Glass Containers to be heated to 70 ℃-120 ℃ deionized water, take by weighing polyvalent metal salt and second linking agent adds above-mentioned deionized water for stirring, be mixed with treatment solution B;
3), treatment solution is to the processing of water-absorbing resin:
Get quantitative water-absorbing resin and place high speed agitator, under stirring state, treatment solution A, treatment solution B are sprayed on the water-absorbing resin surface sequentially through stirring, resin is put into pallet, enter baking oven for heating and carry out crosslinking reaction, temperature of reaction is 100～135 ℃, reaction times is 90～120 minutes, promptly finishes modifying surface of absorption resin of sodium polyacrylate.
Aforementioned dispersion agent adopts ethanol;
Aforementioned linking agent adopts epoxy chloropropane;
Aforementioned polyvalent metal salt adopts aluminium salt;
Second linking agent adopts polyvalent alcohol;
Therefore, the invention has the beneficial effects as follows: the present invention divides two sections, adopt different surface treatment agents, water-absorbing resin is coated, by the optimization of surface treatment agent, the control of mating surface crosslinking reaction condition is under the situation that does not take place obviously to descend at water-retaining capacity, significantly improve liquid permeability, absorption speed, water-retentivity, the gel-strength of resin, obtain the water-absorbing material of Heat stability is good, high comprehensive performance.
