The following performance tests were carried out on the agricultural dispersants prepared in examples 1 to 5 and comparative examples 1 to 5:
(1) reaction conditions
Since styrene was insoluble in water, unreacted styrene was extracted by extraction, and the conversion of the reaction (mass of added styrene-mass of unreacted styrene)/mass of added styrene was measured, and the results are shown in table 1.
TABLE 1 reaction of dispersants of examples and comparative examples
As can be seen from the results in Table 1, the environmentally friendly agricultural dispersants of examples 1-5 of the present invention have stable synthesis process and high conversion rate. In the invention, one component is replaced or the preparation conditions are changed, the monomer conversion rate is low, the appearance of the auxiliary agent is poor, and a large amount of residual monomer exists.
(2) Molecular weight measurement
The molecular weight was measured by GPC using sodium polyacrylate as a standard, and the solution was used for comparative example, and the results are shown in Table 2.
TABLE 2 molecular weight and distribution index of dispersants of examples and comparative examples
The molecular weight is less than 5000, the dispersion effect cannot be achieved, the molecular weight is more than 35000, and the particles cannot be adsorbed on the surfaces rapidly due to the molecular weight. As can be seen from the results in Table 2, the molecular weights of the environmentally friendly agricultural dispersants added in the examples 1-5 of the present invention are within 5000-. One component in the invention is replaced or the preparation condition is changed, the molecular weight does not meet the dispersion requirement, the distribution coefficient is more than 2, and the molecular weight of the dispersant is not concentrated.
(3) Dispersion Performance test
Corn starch, light calcium carbonate and kaolin are common fillers in pesticide preparations, and the dosage is large, and the dispersing suspension performance of the dispersing agent is tested by using the filler. Test methods reference GB/T14825-2006 (method 2), with results in Table 3.
TABLE 3 Dispersion Performance of dispersants of examples and comparative examples
As can be seen from the detection data in Table 3, the environment-friendly agricultural dispersant provided by the invention has good suspension performance on corn starch, light calcium carbonate and kaolin. By replacing one component in the invention or changing the preparation conditions, the dispersion performance of the prepared dispersant is greatly reduced.
The results show that the environment-friendly agricultural dispersant prepared by the invention has the characteristics of complete reaction, simple process and good dispersing performance.
