Reversible phase-change atomized liquid gel containing hydrocarbyl-acylamino-glycosyl-aromatic alkylene four-stage glycosyl gelling agent as well as preparation and application thereof

Abstract

The invention discloses a reversible phase-change atomized liquid gel containing a hydrocarbyl-acylamino-glycosyl-arylene four-stage glycosyl gelling agent, which comprises the following components inpercentage by mass: 0.1-3.0 wt% of a glycosyl gelling agent and 97.0-99.9 wt% of atomized liquid. The chemical structural formula of the glycosyl gelling agent is shown in the specification, whereinA is aromatic alkylene or heteroaromatic alkylene, and R is hydrocarbyl. The atomized liquid gel has thermal reversible and / or shear reversible phase change characteristics, the gel-sol phase change temperature is 145-220 DEG C, and the gel-sol phase change critical shear stress is 60-560Pa. Through heating and / or oscillation, the atomized liquid gel is changed into a sol state from a gel state, and an atomizing agent fixed in the gel is released to form inhalable aerosol; and when heating and / or oscillation is stopped, the sol-state gel is rapidly recovered to a gel state, and the atomizing agent which is not atomized is fixed in the gel network. The atomized liquid gel disclosed by the invention can solve the problem of smoke condensate after suction is stopped and the problem of smoke liquid leakage of an atomizer caused by air pressure change or external force action in transportation.

Description

technical field [0001] The invention belongs to the technical field of gels, and in particular relates to an atomized liquid gel with reversible phase change characteristics and a kind of hydrocarbyl-amido-glycosyl-arylalkylene four-stage sugar-based gelling agent derived from carbohydrates. Its preparation method and application. Background technique [0002] Supramolecular organogels are non-glassy, ​​non-crystalline thermoreversible solid materials comprising a three-dimensional network (solid phase) made of entangled and self-assembled gelling agent fibers and their immobilized organic continuous phase ( liquid phase). Supramolecular organogels contain mainly organic liquids with rheological behavior and solid appearance. The continuous organic phase includes organic solvents, vegetable oils or mineral oils, and the organic solvents that can be gelled include aliphatic and aromatic hydrocarbons, alcohols, silicone oil, dimethyl sulfoxide, and the like. The gelling age...

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
