Embodiment Construction

[0015] The present invention will be described in detail below:

[0016] A method for preparing a water-retaining agent, comprising the following steps,

[0017] S1: Tear off the cotton, shred it, soak it in dilute hydrochloric acid, take the treated Hu cotton, put it in a beaker, add an appropriate amount of distilled water, and heat it on a water bath at 80°C to dissolve it for later use;

[0018] S2: Under the condition of ice-water bath, slowly add NaOH solution dropwise to the above solution while stirring to partially neutralize it, then add compound enzymes composed of 80% and 20% cellulase and pectinase, and ultrasonically oscillate make it evenly mixed;

[0019] S3: Add the initiator sodium persulfate, stir it evenly, put it into a microwave oven, heat it at 160W to polymerize it, take it out after the reaction is complete, dry it in a 95°C drying oven, cut it into pieces, and continue drying to constant weight. Get a water retaining agent.

Abstract

A preparation method of a water retaining agent comprises the steps as follows: placing cotton in a beaker, adding a proper amount of distilled water, and heating the cotton in a water bath pot at 80DEG C to be dissolved for later use; then, slowly dropwise adding a NaOH solution to the solution with stirring under an ice-water bath condition to partially neutralize the solution, adding compoundenzyme, and performing ultrasonic oscillation to uniformly mix the solution; adding an initiator sodium persulfate, stirring the solution uniformly, placing the mixture in a microwave oven, heating the mixture at the power of 160 W to polymerize the mixture, taking out a product after the reaction, drying and cutting the product in a drying oven at 95 DEG C, and continuously drying the obtained product to the constant weight to obtain the water retaining agent. The water retaining agent has biodegradability, enzymolysis resistance and the potential of becoming an environment-friendly material, and the compound water retaining agent with biodegradability, good comprehensive performance and lower production cost is prepared.

Description

technical field [0001] The invention relates to the technical field of biological materials, in particular to a method for preparing a water-retaining agent. Background technique [0002] The development and use of soil water-retaining agents have a positive effect on alleviating drought and improving water use efficiency, but large amounts of water-retaining agents will pollute the environment if they are discarded. It is of great practical significance to research and develop biodegradable water-retaining agents and realize their recycling and regeneration. [0003] Drought is a major concern around the world. Since the 1950s, with the rapid development of industry and the rapid expansion of population, the problem of climate warming and drought has become increasingly prominent. These problems have prompted scientists from various countries to begin to study effective methods to solve the drought problem. [0004] However, most of the water-retaining agents currently u...
