Description

Water aqua containing hydrolysis-resistant organic silicon additive and preparation method thereof
Technical Field
The invention relates to the technical field of agriculture, in particular to an aqueous solution containing a hydrolysis-resistant organic silicon assistant and a preparation method thereof.
Background
The appearance of pesticide makes human beings get rid of the fate of eating by the weather, but simultaneously it also brings the problem of environmental pollution. The current environment-friendly green pesticide has higher creation cost and higher difficulty, the pesticide water aqua has the advantages of small environmental pollution, low toxicity to people and livestock, difficult generation of phytotoxicity, safe storage and transportation and the like, but because the water aqua does not contain an emulsifier, the adhesion performance of the water aqua on the surface of crops is relatively poor, and the pesticide effect is inferior to that of missible oil.
The agricultural organic silicon additive serving as an efficient additive has the following advantages: 1. the pesticide spreading agent is a super strong spreading agent, can wet all plants, spreads the liquid medicine to all hidden parts of crops, and better exerts the pesticide effect; 2. the pesticide is resistant to rain wash, the pesticide liquid remained on the surfaces of crops is only 20-30% in the traditional pesticide spraying, and the amount of the pesticide liquid is less in rainy days. After the agricultural organic silicon additive is used, the pesticide is retained on the surface of crops to a greater extent, so that the utilization rate of the pesticide is improved; 3. the capability of the liquid medicine to penetrate through the pores of the insects is improved, so that better pesticide effect is achieved; 4. can reduce the water consumption and the dosage and save the labor cost. The agricultural organic silicon additive is added into the aqueous solution, so that the surface tension of the aqueous solution can be effectively reduced, and the aqueous solution can exert a greater drug effect. The traditional agricultural organosilicon mainly takes trisiloxane or polysiloxane as a hydrophobic chain, but has the problem of easy hydrolysis, and the surface activity of the organosilicon auxiliary agent can be obviously reduced after the organosilicon auxiliary agent is hydrolyzed, so the organosilicon auxiliary agent can be generally used only as a tank-mixing auxiliary agent and is prepared before application, and the use by farmers is inconvenient. The traditional agricultural organic silicon assistant can keep surface activity for a long time in a pH neutral environment, but is easy to hydrolyze when the pH is too acidic or too alkaline, and at present, a plurality of experts at home and abroad are in research on hydrolysis-resistant organic silicon assistants. Momentov performance materials incorporated discloses a hydrolysis resistant organomodified dioxysilane surfactant (CN101959417A) and a hydrolysis resistant organomodified trioxasilane surfactant (CN103070168A) which are resistant to hydrolysis at a pH of about 3 to 12. Shandong university of agriculture discloses a preparation method of an anti-hydrolysis organosilane surfactant (CN102993225A), which has good anti-hydrolysis capability under acidic conditions. However, currently, there are few silicone adjuvant products that are applied to aqueous formulations.
In view of the above, the present invention is specifically proposed.
