Abstract
The invention discloses a natural component water-retaining agent production technology. The production technology comprises dispersion liquid preparation, fluid suspension mixing and polymerization. The water-retaining agent containing monomer acrylic acid, carboxymethyl cellulose, montmorillonite and humic acid is prepared through a solution polymerization method, has good stability and a low production cost, promotes plant growth and realizes water retaining and fertilizer utilization rate improvement through fertilizer carrying and slow release effects.
Description
Technical field
The present invention relates to fertilizer field, be specifically related to the production technology of a kind of natural constituents water-retaining agent。
Background technology
China is the country that a water resource lacks, and Arid&semi-arid area accounts for the 47% of territory total area, one of water resource important restriction factor becoming the national economic development。Water-retaining agent is also known as super absorbent resin (SAP), the water of own wt hundreds of to thousands of times can be absorbed within a short period of time, and can discharge lentamente, having good application prospect in agricultural gardening etc., the application of water-retaining agent is an effective new way in current water saving, water conservation, soil improvement。Due to the combined influence of fertilizer character with soil environment condition etc., utilization rate of fertilizer is low is common problem on chemical fertilizer application, and excessively using of chemical fertilizer causes soil block to harden and soil permeability reduction。By slow release fertilizer technology and SAP compound, it is the important technology improving utilization rate of fertilizer, water-saving and synergistic that preparation has the slow release fertilizer of water-absorbing-retaining function。The combination of super absorbent resin and fertilizer mainly has mix type, absorbent-type, coating type 3 kinds。Mix type refers to directly with fertilizer, SAP is mixed together to preparation；Coating type refers to fertilizer for core, uses SAP peplos；Absorbent-type refers to dry after being soaked in certain density dissolved fertilizer solution by SAP, pulverizing, has the advantage that preparation technology is simple, cost is low。The SAP of current practice is mainly polyacrylic acid and polyacrylamide polymer, and production cost is high, function singleness。
Summary of the invention
It is an object of the invention to overcome the defect existed in prior art, it is provided that the production technology of the natural constituents water-retaining agent that a kind of Water-saving effect is good。
For realizing above-mentioned technique effect, the technical scheme is that the production technology of a kind of natural constituents water-retaining agent, it is characterised in that comprise the following steps:
S1: montmorillonite and humic acid are distributed in deionized water, ultrasonic 10min；
S2: after being dissolved in deionized water by carboxymethyl cellulose, and the suspension mixing of S1 gained, stir 20min；
S3: take monomeric acrylic, being neutralized to degree of neutralization with the potassium hydroxide solution of 20% is 70%, it is poured in S2 gained mixed liquor, addition cross-linking agent N, N '-methylene-bisacrylamide and initiator potassium persulfate after being sufficiently mixed, the monomer concentration of polymerization system is 25～30%, at 70 DEG C, polyreaction 3～4h, is cut into small pieces product, by washing with alcohol, it is dried to constant weight in an oven, obtains natural constituents water-retaining agent。
Wherein, in S1, the consumption of montmorillonite accounts in S3 the 5～6% of monomeric acrylic weight, and in described S1, the consumption of humic acid accounts in S3 the 5～7% of monomeric acrylic weight。
Wherein, in described S2, the consumption of carboxymethyl cellulose accounts in S3 the 4～6% of monomeric acrylic weight。
Wherein, in described S3, the consumption of cross-linking agent accounts in S3 the 0.11～0.125% of monomeric acrylic weight, and the consumption of described initiator accounts in S3 the 0.5～0.7% of monomeric acrylic weight。
Advantages of the present invention and having the beneficial effects that:
The water-retaining agent containing monomeric acrylic, carboxymethyl cellulose, montmorillonite and humic acid is synthesized by solution polymerization process, this water-retaining agent has good stability, production cost is relatively low, helping lend some impetus to plant growing, load and the slow releasing function of fertilizer are made it improve the utilization rate of fertilizer while water conservation by this water-retaining agent。
