Problems solved by technology

[0004] Fluorocarbon surfactants also have their own disadvantages. Their cost is often higher than that of hydrocarbon surfactants, and under certain conditions, their performance is not as good as that of traditional hydrocarbon surfactants.

Embodiment 1

[0025] In the cross-linking agent system, the surfactant prepared by the above steps is used as a drainage aid, and its addition amount is usually 0.3%. The surface tension of 0.3% in clean water is 21.4mN / m. Its surface tension after curing is 23.3mN / m, which meets the needs of the industry.

Embodiment 2

[0027] When the present invention is used as a wetting agent, the wetting point of the hydrophobic drug by the clear solution with a content of 0.1% is greatly reduced, and the required solvent is greatly reduced.

Abstract

The invention discloses a compounding method of a fluorocarbon surfactant. The method comprises the following steps: step 1, by using distilled water, respectively preparing solutions with the concentration of 1000 ppm from seven substances including a fluorocarbon surfactant, silicone oil, dodecyl dimethyl amine oxide, hexadecyl trimethyl ammonium chloride, dodecylbenzene sulfonic acid, sodium dodecyl benzene sulfonate and fatty alcohol-polyoxyethylene ether sodium sulfate; step 2, compounding the seven solutions with the concentration of 1000 ppm obtained in the step 1 in proportion; 3, diluting the compound solution obtained in the step 2 with distilled water until the concentration is 75ppm. Thefluorocarbon surfactant is high in stability, can not be decomposed in a high-temperature system of 150 DEG C, and stably exists; besides, the chemical inertness is high, and the performance is not obviously changed after the fluorocarbon surfactant is respectively stored in a 90 DEG C hydrochloric acid solution with the mass concentration of 20% and a 2 mol / L sodium hydroxide solution for seven days.

Description

technical field [0001] The invention belongs to the field of surfactants, in particular to a method for compounding fluorocarbon surfactants. Background technique [0002] Fluorocarbon surfactants are an important branch of special surfactants. The difference between them and traditional hydrocarbon surfactants is that all or part of the hydrogen atoms in the hydrocarbon chains of hydrocarbon surfactants are replaced by fluorine atoms, that is to say The fluorine-carbon chain replaces the hydrocarbon chain, and fluorine is the most electronegative element. It has high oxidation potential and high ionization energy. This characteristic makes the fluorine-carbon bond the highest known covalent bond. It can be seen that the fluorocarbon chain structure is far more stable than the hydrocarbon structure. At the same time, the fluorine atoms are also very difficult to be polarized, which makes the fluorocarbon chain far less polar than the hydrocarbon chain. It is precisely becau...
