Description
Technical field
The present invention relates to water-absorbing resin field, the method for a kind of Sorghum vulgare Pers. full powder synthesis hydroscopic high-molecular resin.
Background technology
Sorghum vulgare Pers. is a kind of happiness temperature, happiness light, and Sorghum vulgare Pers. originates in the torrid zone, is happiness temperature crop, and temperature required during giving birth to compares Semen Maydis
Height, and have certain high-temperature stability, the time of infertility preference temperature 20-30 DEG C.Sorghum vulgare Pers. is C4 crop, all needs the time of infertility
Want sufficient illumination.Sorghum vulgare Pers. belongs to short day crop, and any kind can accelerated development under short-day sunshine treatment.Drought resisting, anti-
Flood, Salt And Alkali Tolerance, the prosperity of barren-resistant Sorghum roots, root cells has higher osmotic pressure, absorbs moisture ability from soil
By force.Meanwhile, stem, Ye Biao and have one layer of white waxiness, can desensitization during arid.
High-molecular water-absorption water-retention resin is the novel high polymer functional material that development in recent years is got up, owing to water absorption is very strong, and tool
There are the ability absorbing the most thousands of times of moisture of own wt hundred times, and the moisture that release absorbs when arid, thus can be in work
The aspects such as industry, agricultural and daily life are applied.Complete for Sorghum vulgare Pers. powder introducing acrylic monomers is carried out combined polymerization, height can be made
The full powder of fine strain of millet becomes a kind of material with super-strong moisture absorbing water conservation.
Summary of the invention
It is an object of the invention to provide a kind of water conservation, the method for the effective Sorghum vulgare Pers. full powder that preserves soil moisture synthesis hydroscopic high-molecular resin,
With the problem solving to propose in above-mentioned background technology.
For achieving the above object, the present invention provides following technical scheme:
A kind of method of Sorghum vulgare Pers. full powder synthesis hydroscopic high-molecular resin, concrete steps include:
1) configuration sodium acrylate solution；The acrylic acid of 120g is dissolved in 50ml deionized water, forms acrylic acid solution；
50-60g sodium hydroxide 150ml water dissolution is become sodium hydroxide solution, acrylic acid solution is mixed with sodium hydroxide solution
Preparing degree of neutralization after conjunction is the sodium acrylate solution of 75-90%；
2) complete for 5-12g Sorghum vulgare Pers. powder and 50ml water are inserted in reactor, and at 80 DEG C of gelatinizing 1h, be cooled to 40 DEG C；To third
Olefin(e) acid sodium solution adds 0.1-0.2g cross-linking agent, and the sodium acrylate solution adding cross-linking agent is inserted in reactor,
30min is stirred under nitrogen atmosphere,
3) displacement nitrogen is to become oxygen atmosphere in oxygen makes reactor, adds 0.15-0.2g initiator；It is warming up to 55
DEG C reaction 1h；
4) it is cooled to room temperature；Being dried to biodiversity content is 5-15%, segmentation, 70 DEG C of drying, pulverizes, mistake 150 mesh sieves,
Pack and get final product.
As the further scheme of the present invention: described cross-linking agent uses N, N '-methylene-bisacrylamide solution.
As the further scheme of the present invention: described initiator uses potassium peroxydisulfate.
Compared with prior art, the invention has the beneficial effects as follows: a kind of Sorghum vulgare Pers. product synthesis macromolecule provided by the present invention is inhaled
The method of water-resin, can be applicable to large-scale production, has opened up the value of Sorghum vulgare Pers., has cost low a little, produces control
System is simple, and the performance of gained water-absorbing resin is good.The soil that the super absorbent resin prepared in the process of the present invention is prepared as base material
Water-retaining agent, has good water absorbing properties.Water absorption >=450, moisture-holding capacity >=40, for soil have good water conservation,
Soil moisture conservation performance, and water retention property is sustainable for many years.Hydroscopic high-molecular resin not only water absorption, water-retaining property are splendid, as soil
Modifying agent and water-retaining agent, it can also improve the crumb structure of soil, increase breathability and the water penetration of soil, reduce soil
Earth daytime and the temperature difference in evening.Fertilizer, pesticide can also be absorbed simultaneously, prevent fertilizer, pesticide and soil erosion, and make fertilizer
Material, agricultural, water are slowly released, and improve fertilizer, the effect of pesticide, and are greatly enhanced drought-resistant ability.
