Embodiment 1

[0033] The weight percent of each monomer and water is as follows:

[0034] Acrylamide (AM): 15%

[0035] Acrylic acid (AA): 10%

[0036] Corn starch (ST): 8%

[0037] Methacrylamide (MAM): 3%

[0038] Methacryloxyethyltrimethylammonium chloride (DMC): 3%

[0039] Humate (HA): 8%

[0040] N,N-Methylenebisacrylamide MBA: 0.005%

[0041] Distilled water: 53%

[0042] Preparation of the solution: Add 388g of distilled water and 100g of acrylic acid (AA) into a 2000ml beaker, control the adding speed of potassium hydroxide, keep the system temperature at 70-90°C, and use 62g of potassium hydroxide. At this time, the neutralization degree of acrylic acid is about 80%; dissolve 80g of cornstarch into 80g of distilled water and stir to form starch; add the starch slurry into the neutralized acrylic acid system for gelatinization for 1-2 hours; when the reaction solution cools below 40 degrees, start adding 150g of acrylamide, 30g methacrylamide, 30g methacryloyloxyethyltrimeth...

Abstract

The invention relates to an amphiphilic ionic high polymer soil conditioner and a synthesis method thereof. The soil conditioner can be widely applied in the fields of drought resistance and seedling protection, soil improvement, wind sheltering and sand fixation, water and soil conservation and the like, and is particularly suitable for improving poor soil suffering from soil firmness, hardening, erosion, salinization, acidification, element imbalance, chemical pollution, organic matter loss, degeneration of fauna and flora, and the like. A high polymer grafting and copolymerizing process is adopted, so that intra-intermolecular grafting of humic acid and starch is performed while copolymerization of polymer negative and positive ionic monomers is realized, agglomerates formed by reacting a synthetic product with soil are more natural, and plant growth is facilitated.

Description

technical field [0001] The invention relates to a soil conditioner, in particular to a zwitterionic high polymer soil conditioner, especially suitable for poor-quality soil with unbalanced material composition and abnormal structure, and the production of the zwitterionic high polymer soil conditioner method. Background technique [0002] With the continuous development of economy and society, the problem of soil degradation has become increasingly prominent, mainly manifested as soil compaction and hardening, erosion, salinization, acidification, element imbalance, chemical pollution, loss of organic matter and degradation of flora and fauna, etc., serious The development of land productivity is restricted. Poor quality soil is caused by the imbalance of material composition and abnormal structure. [0003] Aggregate structure is the basic structure of soil with agronomic value. Natural aggregate is a structuring agent formed by soil organic matter. The organic structurin...
