The high water-absorbent resin is a multifunctional polymer material having a certain degree of crosslinking, and the spatial network structure can be applied in many fields due to its excellent water-absorbing and water retentivity. Compared to the starch and cellulose Department of superabsorbent resin, super absorbent acrylic resin preparation process is simple, comprehensive water absorption and excellent mainstream super absorbent resin product of research and re-point. The superabsorbent generally with acid, alkali, salt and poor performance shortcomings, which limits its application, therefore, research and development with good acid, alkali, salt tolerant superabsorbent resin is particularly important. In this paper, the preparation of certain acid, alkali, salt, aqueous salt solutions of different pH adsorption at room temperature and atmospheric pressure for the purpose of super absorbent polymers, the introduction of the interpenetrating network technology, prepared by two interpenetrating network structure of super absorbent acrylic resin. The main research contents include the following aspects: 1. Xanthan gum (XG), polyvinyl alcohol (PVA), acrylic acid (AA) as raw material, potassium persulfate (KPS) as initiator, the use of an aqueous solution of poly legal preparation the XG-AA-PVA interpenetrating network of super absorbent resin, the reaction conditions on the resin absorbency to determine the best synthesis process; tested the water absorption capacity of the resin in the different pH values ??and different salt solutions, was out of a resin having a pH value between 4-10, preferably water absorbency, also on the type of cationic salt solution having a good absorption capacity, water absorption rate, water absorption at saturation can be achieved in 5min; infrared spectroscopy, scanning electron microscopy , thermal gravimetric analysis of the resin structure characterization, proved the presence of interpenetrating network structure, thermal gravimetric analysis also shows that the synthetic the XG-AA-PVA resin heat resistance than pure xanthan gum. 2 with concentrated sulfuric acid sulfonation of polyvinyl alcohol, sulfonated modified polyvinyl alcohol was prepared over sodium (SPS), measured obtaining the degree of esterification of 72% -74%; SPS infrared spectrum at a wavenumber 1134cm-'and 614cm-' at S = O vibration absorption peak of the molecular chain, SPS-OS03-group, the sulfonation reaction is successful. 3 to XG, SPS, AA, as raw material, KPS as initiator, N, N'-sub-methyl-bis-acrylamide (NMBA) as crosslinker prepared XG-AA-SPS interpenetrating network of super absorbent resin, study the reaction conditions the resin absorbency, to determine the optimum conditions; tested XG-AA-SPS resin at different pH values ??and different salt solution in water absorption capacity, results showed that the introduction of sulfonic acid groups, resin acid and alkali resistance, salt tolerance than the original XG-AA-PVA resin have been greatly improved; infrared spectrum shows the presence of sulfonic acid groups in the resin, thermal gravimetric analysis results show that the introduction of sulfonic acid groups to improve the heat resistance of the resin.
