Description
Technical field
The present invention relates to water-absorbing resins field, the method for a kind of rapeseed meal synthesis hydroscopic high-molecular resin.
Background technology
Rapeseed meal is the by-product of Semen Brassicae campestris, the crude protein content about 36% of rapeseed meal, and aminoacid composition relatively balances, sulfur-bearing
Amino acid content is high, and methionine, lysine content are the highest, but less than bean cake, and arginine content is low.The carbon of rapeseed meal
Mostly hydrate is stodgy pentose, containing 8% pentosan, crude fiber content 10-12%, therefore available energy water
Flat low, less than bean cake and the energy of Semen arachidis hypogaeae dregs, but higher than cottonseed meal.The nicotinic acid of rapeseed meal and content of choline are high, carotene,
Vitamin D equal size is low；Calcium, phosphorus, selenium, Fe content height in mineral, but the 60-70% of phosphorus content belongs to phytate phosphorus, utilizes
Rate is low.
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.In rapeseed meal, introduce acrylic monomers carry out combined polymerization, dish can be made
The seed dregs of rice become a kind of material with super-strong moisture absorbing water conservation.Also do not have above materials application at present in preparing macromolecule water uptake guarantor
The report of water-resin.
Summary of the invention
The method that it is an object of the invention to provide the splendid rapeseed meal synthesis hydroscopic high-molecular resin of a kind of water absorption, water-retaining property,
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 rapeseed meal 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；
50g sodium hydroxide 150ml water dissolution is become sodium hydroxide solution, after being mixed with sodium hydroxide solution by acrylic acid solution
Prepare sodium acrylate solution；
2) 5-10g rapeseed meal and 50ml water are inserted in reactor, and at 80 DEG C of gelatinizing 1h, be cooled to 40 DEG C；To propylene
Acid sodium solution adds 0.2-0.3g cross-linking agent, and the sodium acrylate solution adding cross-linking agent is inserted in reactor, at nitrogen
Atmosphere encloses lower stirring 30min,
3) displacement nitrogen is to become oxygen atmosphere in oxygen makes reactor, adds 0.19-0.2g initiator；It is warming up to 55
DEG C reaction 1-5h；
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 rapeseed meal can directly use or re-use after treatment；Wherein process
Process: after being soaked by rapeseed meal, squeezes into pressure filter the solution after immersion and carries out filter pressing, and the filtrate after filter pressing is dried
Dry standby i.e. obtain the rapeseed meal after process.
As the further scheme of the present invention: the degree of neutralization of described sodium acrylate solution is 75%.
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 Semen Allii Tuberosi 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 Semen Allii Tuberosi, has the advantage that cost is low, 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.
The present invention is that the deep processing of Semen Allii Tuberosi product opens an approach with application.In terms of Tailings Dam, heavy metal is all extracted
Rear addition hydroscopic high-molecular resin, the arable land that can realize reclaiming, afforest, plant trees, sandy soilization transformation, reach heavy metal-polluted
Dye administers purpose, simultaneously can be used for the pollution control of flyash stack-up-yard, after improvement and can realize second ploughing, for enterprise's extra earning
Abundant profit.
