Description
Technical Field
The utility model relates to the technical field of preparation equipment of amphiphilic particles, in particular to a reaction kettle for preparing the amphiphilic particles by a Pickering emulsion template method.
Background
The surface of the amphiphilic particles has the characteristics of excellent wettability, surface activity, emulsification and the like due to the anisotropy of the hydrophilicity and the hydrophobicity of the surfaces of the amphiphilic particles, and has wide application prospect.
Pickering emulsion: is a novel emulsion with solid particles replacing the traditional organic surfactant to stabilize an emulsion system. Emulsions (emulsions) are dispersions of two mutually immiscible liquid phases in which the internal or dispersed phase is dispersed in the external or continuous phase in the form of droplets, i.e. without the need for amphiphilic surfactants to reduce the interfacial tension, stable emulsions can be prepared by dispersing directly colloidal particles in the emulsion in the colloidal size range, emulsions which are stabilized solely by the colloidal particles are known as Pickering emulsions.
Pickering emulsions are emulsions stabilized by solid particles (e.g., colloidal SiO 2) adsorbed to the interface of the two phases. This phenomenon was first discovered by Walter Ramsden in 1903 and was further described by s.u. Pickering in 1907. If the oil and water are mixed, small oil droplets form and disperse in the water, and eventually the droplets coalesce to reduce energy. However, if solid particles are added to the mixture, they will be bound to the surface of the interface to prevent coalescence of the droplets, thereby stabilizing the emulsion.
Compared with emulsions stabilized by conventional surfactants, pickering emulsions have certain advantages:
1. the dosage of the emulsifier can be greatly reduced;
2. the toxicity to the environment is far less than that of the surfactant;
3. is environment-friendly;
4. the emulsion has strong stability and is not easily influenced by factors such as the pH value of a system, the salt concentration, the temperature, the oil phase composition and the like.
The paraffin is used as the oil phase, the structure of the surface of the amphiphilic particles can be quantitatively changed by preparing the amphiphilic particles by a Pickering emulsion template method, and industrial production is easier to perform than other synthetic methods. In the process of preparing the amphiphilic particles by a Pickering emulsion template method, the working procedures of heating, cooling, filtering, changing a reaction solvent and the like are involved.
The existing method adopts a method of replacing a reaction container to carry out the synthesis process step by step, and has the problems of complex operation of the process, low efficiency and the like.
