Embodiment 1

[0016] Example 1: Dissolve 6.0g of sodium hydroxide with 19ml of deionized water, and neutralize 27g (25.6ml) of acrylic acid under cooling and stirring in an ice-water bath; dissolve 0.01g of sodium fulvic acid with 25ml of deionized water, and then add neutralization Good acrylic acid and its sodium salt solution, 10g of dehydrated MS medium, 100mg of potassium persulfate, 6ml of N,N'-methylenebisacrylamide solution with a concentration of 5mg / ml, stirred at room temperature for 1.0h, and then passed nitrogen gas And start to heat slowly, make it react at 60-80°C for 1h, continue to heat up, keep warm in a boiling water bath for 1.5h, stop nitrogen, cool to room temperature, take out the product, dry, crush, and sieve to obtain The superabsorbent resin containing sodium fulvic acid and dehydrated MS medium, the water absorption of the product obtained in this example is 725 times.

Embodiment 2

[0017] Embodiment 2: The experimental conditions are the same as in Embodiment 1, except that 0.05 g of sodium fulvic acid is dissolved in 25 ml of deionized water, and the water absorption ratio of the product obtained in this embodiment is 530 times.

Embodiment 3

[0018] Embodiment 3: The experimental conditions are the same as in Embodiment 1, except that 0.1 g of sodium fulvic acid is dissolved in 25 ml of deionized water, and the water absorption ratio of the product obtained in this embodiment is 760 times.

Abstract

The invention discloses a method for preparing super absorbent resin containing fulvic acid sodium and an MS dry medium. In the process of synthesizing the super absorbent resin, the fulvic acid sodium and the MS dry medium are added, and the super absorbent resin replacing agar to serve as a coagulator of a culture medium, so that the culture medium has proper coagulability and has support function for the cultured plant tissues, nutrient substances are easy to disperse in the absorbent resin, and the nutrient absorption efficiency is improved. Meanwhile, the super absorbent resin has high water absorbing and retaining capacities and reversibility of water absorption and water release, so the plant tissues are facilitated to effectively utilizing water, watering frequency is reduced, andwater and labor are saved. The synthesis process is simple; and the product also contains the fulvic acid sodium capable of regulating plant growth, so the product has wider application prospect and higher promotion value.

Description

technical field [0001] The invention relates to a superabsorbent resin and a preparation method thereof, in particular to a method for preparing a superabsorbent resin containing sodium fulvic acid and dehydrated MS medium. The superabsorbent resin prepared by the invention is mainly suitable for plant tissue culture. Background technique [0002] Super Absorbent Polymer (SAP) is a new functional polymer material with excellent water absorption and water retention. It can absorb water hundreds or thousands of times its own weight and swell into a gel. Water will not precipitate under a certain range of pressure, and the resin gel after water absorption can restore its water absorption performance after drying, so it has important applications in many fields. For example, it is used in baby diapers, women's sanitary napkins, drug slow-release materials, etc. in medicine and hygiene. It is used as an oil-water separator, desiccant, deodorant, cable and tunnel construction in i...
