Description
Technical field
The present invention relates to a kind of slow-release humic acid water-holding agent, more particularly relate to a kind of polyacrylic acid/attapulgite clay/humic acid microsphere water-loss reducer and preparation method thereof.
Background technology
Water-holding agent with slow-release fertilizer function, its preparation method is a kind of to be that fertilizer is wrapped in the water-holding agent simply, another kind is the chemical reaction that makes the two that certain form take place, thereby both are combined.People such as Guo are water-soluble with fertilizer such as ammoniacal liquor, urea and Secondary ammonium phosphates, during polyreaction these compositions are wrapped in carboxymethyl starch-g-vinylformic acid water-holding agent network, obtain having the water-holding agent of slow-release nitrogen fertilizer and phosphate fertilizer.Fertilizer mainly is to be combined on the resin network by hydrogen bond and Van der Waals force, but also has simultaneously the physics filling form to be present in fertilizer in the resin network, and release rate is very fast.By esterification phosphate bond is incorporated on the polyvinyl alcohol, can obtains having the water-holding agent of slow-release phosphate fertilizer function.By starch or polystyrene coated carbamide particle, pass through inverse suspension polymerization or surface-crosslinked then, also can obtain urea is had the water-holding agent of certain sustained release performance.
Humic acid is the important substance that constitutes the soil nutrient composition, has the resistance that stimulating plant grew, increased crop, the effect of improving the nutritional status of plant, can improve guarantor's fertilizer, the water retention capacity of soil.Humic acid is distributed with carboxyl, hydroxyl, carbonyl isoreactivity functional group in structure, be the material of a kind of multipolarity functional group, can generate water soluble salt, has good coordination, crab is closed and the chemical reaction ability.Therefore, humic acid can with hydrophilic natural macromolecule generation graft copolymerizations such as hydrophilic monomers such as vinylformic acid or starch, make prepared water-holding agent have the synergistic function of suction, water conservation and nutrient soil.We carry out composite polymeric with sodium humate and vinylformic acid or acrylamide, humic acid is chemically bonded on the resin network, has obtained sodium humate is had the water-holding agent (application number 200610042899.9 has composite nanometer water retainer of fertilizer slow-released function and preparation method thereof) of certain sustained release performance.But the powdery product rate of release is very fast when reality is used.
Attapulgite clay is a kind of zeopan mineral of chain layer structure, has the duct of numerous nanoscales that are parallel to each other, and has the good adsorption performance.Utilize the absorption property absorption humic acid of attapulgite clay, and then utilize the polymerizability of attapulgite clay and vinylformic acid or acrylamide, design and development have the microsphere water-loss reducer of slow-release function.
Summary of the invention
Purpose of the present invention just provides a kind of microballoon compound water retaining agent with fertilizer slow-released function.
The present invention can realize by following measure:
Adopt attapulgite, humic acid and vinylformic acid main raw material as water-holding agent, earlier microballoon is made in the attapulgite granulation, behind the absorption humic acid, under the condition that initiator and linking agent exist, in the aqueous solution, make microsphere water-loss reducer with fertilizer slow-released function through copolymerization, crosslinked, washing, drying.
Attapulgite be a kind of tool chain laminate structure contain Shuifu County's magnesium silicate clay mineral, its structure belongs to 2:1 type clay mineral.There is three types adsorption center on the attapulgite clay surface: (1) silicon-oxy tetrahedron layer is supplied with Sauerstoffatom because of light current that the isomorphism displacement produces, and they are very weak with the effect of absorption nuclear.(2) at fiber edge and metallic cation Mg
2+Coordinate crystal water molecule (OH
2), it can become hydrogen bond with the absorption karyomorphism.(3) the Si-OH base that is formed by the bond rupture of Si-O-Si bridging oxygen on the tetrahedrallayer outside surface not only can be accepted ion, and can mutually combine with the adsorbed molecules of crystal outside surface, can also form covalent linkage with some organic reagent.Attapulgite clay can be by physical adsorption and chemisorption adsorbent owing to bigger surface-area is arranged.The essence of physical adsorption is the surfaces externally and internally that adsorption molecule is adsorbed on attapulgite clay by Van der Waals force; Chemisorption is intermolecularly to form adsorption center on attapulgite clay surface through chemical bond.Humic acid is the material of a kind of multipolarity functional group, is distributed with carboxyl, hydroxyl, carbonyl isoreactivity functional group in the structure, thereby adsorbed by attapulgite clay.
A kind of slow-release humic acid microsphere water-loss reducer is characterized in that raw materials in part by weight is: 100 parts in vinylformic acid, attapulgite 10-50 part, humic acid 20-60 part, initiator 0.05-1.0 part, linking agent 0.05-1.0 part; Wherein linking agent is N, N ' methylene-bisacrylamide; Initiator is selected from ammonium sulfate or Potassium Persulphate.
Preparation method with fertilizer slow-released function microsphere water-loss reducer is, vinylformic acid is added in the reactor, after adding dissolved in distilled water, add absorption humic acid attapulgite clay microballoon, linking agent and initiator again, be warming up to 40-70 ℃ of reaction 2-4 hour, after reaction finished, product was with containing the methanol in water washing, under 60-80, dry drying to constant weight.
Attapulgite is selecting and purchasing and getting from natural crystal, carries out granulation after crushed, and particle diameter is between 1-10mm.
The attapulgite microballoon is placed the saturated solution of humic acid, adsorb saturated after, directly add and carry out in-situ polymerization in the reaction system.Adopt the attapulgite microballoon of different diameter, the amount difference of its absorption humic acid, its slow-release time is also different.
The present invention has the following advantages: when the microballoon of (1) preparation contacts with water, dissolving diffusion to parcel or bonded humic acid behind the microballoon water absorption and swelling produces stopping effect, the release rate of humic acid is slowed down, make the existing certain suction of the product that makes, water-retaining effect, have certain fertilizer efficiency, slow-releasing again; (2) owing to used humic acid, make matrix material have the function of slow release fertilizer, experiment test shows that the sustained release performance of this matrix material reached more than 40 days; (3) this matrix material suction multiple has reached 300-500g/g, has satisfied under the drought condition requirement to water-absorbing-retaining material; (4) use back soil physical chemistry performance test to show that this microballoon has better soil improvement action than common matrix material.
The water-holding agent characteristics are both to have kept product to use plurality of advantages on agricultural, slowly discharge nutrient can for again crop, have the potential application prospect.
