Abstract

The invention discloses a production process for preparing an organic-inorganic composite water-retaining agent. a. After mixing sodium hydroxide and deionized water, add it to acrylic acid under the condition of ice-water bath to obtain product A; b. Mix titanium dioxide dispersion liquid with deionized water to obtain product B; c. Mix product A, After mixing product B and acrylamide, pour it into a quartz tube, and irradiate it with ultraviolet light under a nitrogen atmosphere to obtain a photopolymerization product, which is product C; d. Mix N,N-methylenebisacrylamide, ammonium persulfate and Mix with deionized water to obtain product D; e, under nitrogen atmosphere, mix and heat product C and product D to obtain product e; f, soak product e with alcohol and dry to obtain the finished product. The invention solves the problems of loose organic-inorganic interface of the water-retaining agent and difficult degradation after repeated use, prevents the water-retaining agent from becoming the next "white pollution", and improves the tightness of the organic-inorganic interface of the water-retaining agent and realizes repeated use. Significant in terms of degradation.

Description

Technical field [0001] The present invention relates to a water reservoir, in particular a new type of production process for preparing organic-inorganic composite water repellent. Background technique [0002] The problems such as drought, soil loss, desertification, and sandstorms have become the main ecological problem facing the world. Especially in the shortage of water resources, agricultural production activities have been greatly limited, so the soil drought resistance is solved, and water water has become a hot spot in the current research. [0003] The water storage agent is a polymer compound that absorbs a few hundred or even thousands of water in a short period of time, and can slowly release, with excellent water absorption, water supply performance, in agricultural production, drug delivery, daily life, etc. Aspects have been widely used. The conventional water retention agent is excellent in water storage performance, but there is a defect such as poor strength, m...
