Description
Technical field
The invention belongs to water-loss reducer technical field, be specifically related to a kind of anatonosis and expand the macromolecule resin material holding, mainly applicationIn crop water-loss reducer, the aspects such as Soil infiltration water-retaining film.
Background technology
Super water-absorbent resin is that one contains the strongly hydrophilic such as hydroxyl, carboxyl group, and has the water-soluble of certain degree of cross linkingThe functional high molecule material of swollen type and tridimensional network is that a class developed Novel absorbent material rapidly in recent years. It is notWater-soluble and organic solvent, swelling after water suction, form hydrogel, there is certain intensity and water-retaining property. With traditional water-absorption materialMaterial is compared has larger advantage. But be all super absorbent resin, due to raw material, preparation method's difference, its water absorbent rate byHundred times to thousand times are not etc. And the release And Spread of Solute of single super absorbent resin after field application, water suction, and cannot provideThe nutrient problems that farmland needs etc., have therefore restricted its application in agricultural production reality.
Summary of the invention
Be not suitable in order to overcome existing super water-absorbent resin the shortcoming that farmland is used, the present invention discloses a kind of novel super absorbentProperty resin--containing the compound permeability/retentivity enhancing material of macromolecule of humic acid-acrylic acid-carboxymethyl cellulose, can not only solve swelling afterThe problem that discharges moisture, can also solve the problem that organic nutrient is provided to farmland.
For addressing the above problem, technical scheme of the present invention is: at alkali condition, pass into external inert gas environment (15-30min), in the reaction system that contains humic acid, fully stir, under room temperature with potassium peroxydisulfate cause (crosslinking agent is N,N-methylene-bisacrylamide) acrylic acid reacts with carboxymethyl cellulose, thereby obtains super absorbent resin raw material. ProcessWashing, dry, shear granulation obtains being applicable to the super water-absorbent resin material in farmland.
The compound permeability/retentivity enhancing material of macromolecule of the present invention by weight percentage each constituent content is: humic acid 2% or3%, acrylic acid 82% or 83%, carboxymethyl cellulose 13% or 14%, potassium peroxydisulfate 0.02%, N-methylene-bisacrylamide0.01%, phosphite ester 0.01%.
The preparation method of the compound permeability/retentivity enhancing material of macromolecule of the present invention comprises the following steps:
1. take raw material by the compound permeability/retentivity enhancing material percentage by weight of macromolecule;
2. raw material step 1 being taken is by humic acid, acrylic acid, carboxymethyl cellulose, potassium peroxydisulfate, N-di-2-ethylhexylphosphine oxide thirdThe order of alkene acid amides, phosphite ester, is added in the alkaline solution of sodium hydroxide of reactor, and mixes, wherein said hydrogenThe weight of sodium oxide molybdena alkaline solution > weight of 2 times of raw materials, the concentration of alkaline solution of sodium hydroxide is 10%;
3. in the raw material of processing through step 2, pass into nitrogen 15-30min, under 500 revs/min of rotating speeds, stir 10-30min;
4. the raw material of processing through step 3 is put under room temperature and fully reacted 2-4h, hygrometric state synthetic is taken out;
5. wash processing through step 4 the hygrometric state synthetic distilled water obtaining, be then placed in 40-60 DEG C of baking ovenBe dried, dry to constant weight or moisture content < 8%, carry out shear granulation to 0.1-4mm, the sub compound anatonosis expansion that secures satisfactory grades is heldFinished material.
In the time making Soil infiltration water-retaining film with the compound permeability/retentivity enhancing material of macromolecule, need to add < 1% film forming agent-poly-Ammonia ester acrylate, and omit the granulation process of step 5 in the preparation method of the compound permeability/retentivity enhancing material of macromolecule.
The compound permeability/retentivity enhancing material usage of macromolecule has dry and wet way:
1) dry method: compound macromolecule permeability/retentivity enhancing material particle and seed are sowed simultaneously, and trench digging is poured water, then earthing,Now this material can start to bring into play Water storage.
2) wet method: compound macromolecule permeability/retentivity enhancing material particle is first soaked to 2-5 hour with clear water, then pull out, with kindSow the sub-same period.
The present invention can discharge the moisture of saving after fully swelling, can provide again the height of the required organic nutrient of soil to inhaleWater-base resin; The present invention can be used for agricultural, forestry and gardens industry plant water keeping drought resisting, reduces moisture evaporation, improves soil texture,Increase soil organic nutrient humic acid content 0.03-0.05%, the implicit ability that improves moisture is about the 325-392 of soil itselfDoubly.
