Novel production process for preparing organic-inorganic composite water retaining agent

The invention discloses a novel production process for preparing an organic-inorganic composite water retaining agent. The novel production process comprises the following steps: a, mixing sodium hydroxide with deionized water, and adding the obtained mixture into acrylic acid under the condition of an ice water bath so as to obtain a product A; b, mixing titanium dioxide dispersion with deionizedwater to obtain a product B; c, mixing the product A, the product B and acrylamide, pouring the obtained mixture into a quartz tube and carrying out ultraviolet irradiation in a nitrogen atmosphere to obtain a photopolymerization product, i.e., a product C; d, mixing N,N-methylenebisacrylamide, ammonium persulfate and deionized water to obtain a product D; e, mixing and heating the product C andthe D product in the nitrogen atmosphere to obtain a product e; and f, soaking the product e in alcohol and then carrying out drying so as to obtain a finished product. The novel production process inthe invention solves the p
