Reversible phase change atomized liquid gel containing glycosyl-aryl-amide-hydrocarbyl four-segment sugar-based gelling agent and its preparation method and application

Abstract

The invention discloses a reversible phase-change atomized liquid gel containing glycosyl-aryl-amido-hydrocarbyl four-stage sugar-based gelling agent, which includes: sugar-based gelling agent, 0.1-3.0wt%; mist Chemical liquid, 97.0-99.9 wt%; the chemical structural formula of the sugar-based gelling agent is: wherein: S is a sugar group; A is an arylene group, or a heteroarylene group; R is a hydrocarbon group. The atomized liquid gel of the present invention has thermal reversible and / or shear reversible phase transition characteristics, its gel-sol phase transition temperature is 190°C-240°C, and its gel-sol phase transition critical shear stress is 85-700Pa. Under heating and / or shaking, the atomized liquid gel changes from a gel state to a sol state, and the fixed atomizing agent in the gel is released to form an inhalable aerosol; when the heating and / or shaking is stopped, the sol state gel rapidly Return to the gel state, and the aerosol that has not been atomized in the gel is re-fixed in the gel network. The atomized liquid gel of the present invention can solve the problem of smoke liquid leakage of the atomizer caused by smoke condensate after the suction is stopped, as well as changes in air pressure or external force during transportation.

Description

Technical field [0001] The present invention belongs to the technical field gel, and particularly to a group derived from a saccharide containing saccharide - aryl - amido - atomized liquid gel having a reversible phase transition type four glycosylation hydrocarbon gelling agent and preparation method and application. Background technique [0002] Supramolecular organogel is a non-glassy, ​​non-crystalline solid thermally reversible material, is fixed by the winding comprising a gelling agent and a self-assembled three-dimensional network fibers prepared (solid phase) and the continuous organic phase ( liquid phase). The main component contained in the supramolecular organogel is an organic liquid having a solid rheological behavior and appearance. A continuous organic phase comprising organic solvents, vegetable or mineral oils, wherein the gelling organic solvents are aliphatic and aromatic hydrocarbons, alcohols, silicone oils, dimethyl sulfoxide and the like.

Problems solved by technology

The former brings the practical problems of increased R&D costs, complicated structure and manufacturing process. In addition, air circulation is required during the use of the atomizer, and it is impossible to completely isolate the atomizer from the outside atmosphere, so it is still difficult to control the leakage of e-liquid; The solid (semi-solid) e-liquid involved in the latter not only has a complicated preparation process, but also has no reversible phase transition performance or a low phase transition temperature, that is, it can only be melted by heat and cannot return to the original solid state (semi-solid) Or it needs to be cooled to a lower temperature (such as 40°C) to restore the original solid state (semi-solid), resulting in solid (semi-solid) e-liquid even if it can improve the leakage of e-liquid during storage and transportation, but the ambient temperature is slightly higher , slight vibration, and repeated temperature rises and falls in the use of electronic cigarettes, etc., the solid (semi-solid) e-liquid will liquefy and it is difficult to return to its original solid state (semi-solid), and as a result, there is still the problem of e-liquid leakage
