Abstract
The invention discloses an all-round penetration spreading agent, which comprises the following components in percentage by weight: 20-28% of octyl phosphate; 30-40% of double-tail trisiloxane surfactant; 26-35% of fatty alcohol-polyoxyethylene ether sulfonate; 1-3% of an auxiliary agent; the balance of water. When the surfactant is used as a wetting agent or a spreading agent, the surfactant can be selectively used at higher temperature and/or humidity, and the product has extremely strong permeability and emulsifying and spreading capacity, and can reach saturated adsorption at lower concentration, so that the use concentration of the surfactant can be greatly reduced.
Description
Technical Field
The invention relates to a spreading agent, in particular to a full-function permeable spreading agent.
Background
The penetrant is a substance which has the functions of penetration, has fixed hydrophilic and lipophilic groups, can be directionally arranged on the surface of the solution, and can obviously reduce the surface tension. Penetrants are generally classified into two categories, nonionic and anionic. Nonionic materials include JFC (fatty alcohol-polyoxyethylene ether), JFC-1, JFC-2, JFC-E, and the like; the anion comprises a rapid penetrant T, an alkali-resistant penetrant OEP-70, an alkali-resistant penetrant AEP, a high-temperature penetrant JFC-M and the like.
Whether the pesticide sprayed on the plant leaves can effectively wet the spread leaf surfaces is the key for directly influencing the insecticidal effect, saving water and pesticide and reducing the damage of the pesticide to the environment.
Existing penetrants are generally obtained by ethoxylating natural triglycerides. As is known in the art, natural triglycerides are not pure substances but rather complex mixtures, the exact composition of which varies depending on the source. Alkoxylation of complex triglycerides can be difficult, thereby leading to an even more complex series of alkoxylated triglyceride products.
Thus, there is a need for penetrants for agrochemical applications, which are produced by different processes that enable higher reproducibility, flexibility and control of the synthesis process, so that more well-defined and/or purer products can be prepared.

Effect of temperature and humidity on spreading ability:
dripping 1L of two-tailed trisiloxane surfactant solution on paraffin and polyester, controlling the temperature to be 20-40 ℃, wherein the spreading of the 1L of solution on the paraffin and the polyester is increased along with the temperature rise; however, the spreading rate and temperature of the 1L solution on paraffin wax had a better effect on its spreading than on polyester.
The same occurs in the effect of humidity on the spreading performance, controlling humidity to 50-90%,
when the humidity is more than 70%, the effect of the humidity on spreading is significantly greater than the effect of the temperature on spreading.
This is probably because increasing the temperature and humidity favours the formation of a film of water with greater surface tension at the leading edge of the spreading droplet, promoting superspreading. Indicating that spreading of the surfactant solution on the solid is also related to the surface energy or surface properties of the substrate.
The double-tail trisiloxane surfactant is added into the spreading agent, and is adsorbed on the interface in an oriented way, namely the hydrophilic group is towards water, and the lipophilic group is towards oil, so that the tension of an oil-water interface can be reduced to meet the spreading condition; and due to the strong electrostatic attraction effect between the different electric hydrophilic groups, the molecules of the surfactant can reach saturated adsorption at lower concentration, so that the use concentration of the surfactant can be greatly reduced.
Therefore, the double-tail trisiloxane surfactant is matched with the fatty alcohol-polyoxyethylene ether sodium sulfonate for use, so that the surface tension of an aqueous solution and the interfacial tension of oil/water can be effectively reduced, the use concentration of the surfactant is greatly reduced, and a thick and stable non-emulsified liquid film can be generated to be spread on the surface of fuel or other liquid.
The product is colorless to yellowish transparent oily matter, and has the following permeability: 0.1% < 10s (25 ℃), the surfactant can be selected to be used under higher temperature and/or humidity when being used as a wetting agent or a spreading agent, the product has extremely strong permeability and emulsifying and spreading capacity, turbid floccule can appear when the environmental temperature is lower than 15 ℃, the product can be solidified when the environmental temperature is lower than 0 ℃, the quality is not influenced, and the appearance is recovered by slightly heating 30-40 ℃ when the product is used.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
