Reversible phase change atomized liquid gel containing hydrocarbyl-amino-glycosyl three-stage glycosyl gelling agent as well as preparation method and application thereof

Abstract

The invention discloses a reversible phase change atomized liquid gel containing a hydrocarbyl-amino-glycosyl three-stage glycosyl gelling agent, which comprises the following components in percentageby 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, wherein R1 and R2 are hydrocarbyl. The atomized liquid gel disclosed by the invention has a thermal reversible phase change characteristic and / or a shear reversible phase change characteristic, the gel-sol phase changetemperature is 135-160 DEG C, and the gel-sol phase change critical shear stress is 55-330Pa. Under 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 rapidly recovers to a gel state, and the atomizing agentwhich is not atomized in the gel is fixed in the gel network again. 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 transition characteristics and a preparation method and application thereof containing a hydrocarbon-amino-glycosyl three-stage sugar-based gelling agent derived from carbohydrates . 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 ag...

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
