Abstract
The invention discloses a permeability/retentivity enhancing material containing humic acid-carboxymethyl cellulose and a preparation method thereof. The preparation method comprises the following steps: proportionally weighing raw materials, sequentially mixing humic acid-acrylamide and carboxymethyl cellulose-crosslinking agent-initiator, and making an inert gas (nitrogen) environment in a reaction kettle to prepare for reaction; and sufficiently reacting the prepared mixture at constant temperature of 45-65 DEG C for 2-6 hours, taking out, washing, drying and granulating. The permeability/retentivity enhancing material containing humic acid-carboxymethyl cellulose not only can release retained moisture after sufficiently swelling, but also can provide ultra-water-absorptive resin which can provide organic substances required by soil; and the permeability/retentivity enhancing material containing humic acid-carboxymethyl cellulose can be used for plant moisture retention and drought control in agriculture, forestry and horticulture as well as preparation of antiseepage moisture retention membranes, satisfy the moisture demands for seedling emergence and early growth of crops, reduce the evaporation, improve the soil structure, increase the content of organic nutrient (humic acid) in soil by 0.3-1.3%, and enhance the moisture retentivity by 250-480 times as compared with the original soil.
Description
Technical field
The present invention discloses a kind of anatonosis expansion that contains humic acids-carboxymethyl cellulose and holds material, and prompting also provides this anatonosis expansion to hold material and got the preparation method, belongs to agricultural crops water conservation and soil antiseepage water conservation technical field.
Background technology
In the modern agricultural technology field, the water-keeping material of farm crop is a lot, as: super water-absorbent resin is a kind ofly to contain strongly hydrophilic groups such as hydroxyl, carboxyl and have the water swelling type of certain degree of crosslinking and the functional high molecule material of tridimensional network, is that a class developed novel rapidly water-absorbing material in recent years; Its water insoluble and organic solvent, suction back swelling forms hydrogel, has certain intensity and water-retentivity.Compare with traditional water-absorbing material and to have bigger advantage.But be all super absorbent resin, because raw material and preparation method's difference, its water absorbent rate does not wait to thousand times by hundred times.And single super absorbent resin after the farmland use to also have suction the release problem and nutrient problem that the farmland needs etc. can't be provided, therefore, restricted its application in agriculture production reality.
Summary of the invention
The present invention discloses a kind of anatonosis that contains humic acids-carboxymethyl cellulose and expands and hold material, solved super absorbent resin discharges moisture after the swelling in the farmland problem, can also provide organic nutrient for the farmland.
The present invention also provides the anatonosis expansion that contains humic acids-carboxymethyl cellulose to hold preparation methods, is applicable to suitability for industrialized production.
The present invention discloses a kind of anatonosis expansion that contains humic acids-carboxymethyl cellulose and holds material,Mainly make by the raw material of following ratio of weight and number:
2 ~ 3 parts of humic acidss, 58 ~ 82 parts of acrylamides, 13 ~ 20 parts of carboxymethyl celluloses, 0.02 part of initiator potassium persulfate, 0.01 part of linking agent N,N methylene bis acrylamide.
Also can add in the above-mentioned prescription: 0.01 part of stablizer phosphorous acid ester, 1 part of membrane-forming agent acrylic resin urethane copolymer resins.
Preparation methods is held in anatonosis expansion of the present invention, may further comprise the steps:
Take by weighing raw material according to the above ratio, according to the order of humic acids-acrylamide and carboxymethyl cellulose-linking agent-initiator add mix after, and make rare gas element (nitrogen) environmental preparation reaction in the reactor; Ready mixture is placed 45-65 ℃ down fully reaction 2-6 hour of constant temperature, and after the taking-up, washing is dry, and granulation obtains containing the expansion of humic acids-carboxymethyl cellulose and holds finished material.
The enforcement usage of product of the present invention comprises dry method and wet method:
1) dry method is about to anatonosis of the present invention and expands and hold material granule with seed is sowed simultaneously, earthing then, and trench digging is poured water, and this material can begin to bring into play the retaining effect at this moment.
2) wet method is about to anatonosis of the present invention and expands and hold material granule and soak with clear water earlier and pulled out then in 2-5 hour, sows the same period with seed to get final product.
Positively effect of the present invention is:In containing the reaction system of humic acids, come reaction acrylamide triggered and carboxymethyl cellulose under the alkaline condition, make the anatonosis expansion and hold starting material with Potassium Persulphate; Obtain being applicable to the super water-absorbent resin material in farmland again through washing, drying, shear granulation.Product of the present invention can provide the super water-absorbent resin of the needed organic matter of soil again fully discharging the moisture of saving after the swelling; Can be used for agricultural, the drought resisting of forestry horticulture plant water keeping, the preparation of soil antiseepage water-retaining film (needing to add membrane-forming agent), can also solve simultaneously that crop emerges and the moisture needs of early growth, reduce evaporation, improve Soil structure, increase soil organic nutrient humic acids content 0.3-1.3%, the implicit ability that improves moisture is 250-480 a times of soil itself.
