Description

Aerosol generating matrix, and preparation method and application thereof Technical Field The invention relates to the technical field of electronic atomized liquid, in particular to an aerosol generating substrate, a preparation method and application thereof. Background The mainstream electronic cigarette atomized liquid generates a large amount of aerosol and needs the atomizer to work under extremely high power, which accelerates carbonization and loss of an atomization core and shortens the service life of the atomization core. This also results in high power consumption of the device, requiring frequent recharging or battery replacement. In addition, the primary solvent PG in e-cigarette tar is responsible for the flavor bearing and VG is responsible for aerosol generation. In pursuit of large smoke, the industry generally employs high VG formulations, but this often dilutes the flavor intensity. For the industry, developing low aerosol or no aerosol electronic cigarette products is a key direction of technical iteration of the electronic cigarette industry, and can open up a brand new and heretofore inaccessible use prospect. The use of electronic cigarettes in public places is currently being restricted by legislation in multiple countries and regions worldwide, the core reason being the second-hand aerosols that they produce. The low aerosol or no aerosol products can greatly improve the compatibility of the products and the supervision environment, and paves the way for the sustainable development of the industry. In addition, the pursuit of a technical route of 'high-efficiency nicotine transmission and low environmental impact' is helpful for remolding serious public images of electronic cigarettes as harm-reducing products, and gets rid of negative public opinion. For consumers, the low aerosol or no aerosol product can greatly improve the convenience and privacy of use (such as libraries, meeting rooms and elevators), and meanwhile, the low aerosol or no aerosol product can be more focused on enhancing the concentration of flavor substances and the transfer efficiency of nicotine, and more satisfied experience can be obtained by using less inhalation amount. There have been attempts to reduce aerosols by changing the solvent system, such as providing a water-based aerosol-generating substrate, aimed at reducing aerosols by replacing part of the glycerol with water, but this solution has a fundamental technical limitation in that it is merely a physical replacement and dilution concept that fails to systematically address the overall user experience problem under low aerosol conditions. The introduction of water as a solvent of a distinct nature presents a new series of technical challenges. Firstly, the concentration of the essence can be diluted by introducing water, and the dissolubility and volatility of many traditional essences in a water-based system are poor, so that the flavor is distorted, the taste is light, the layering sense is fuzzy, and the clarity of the product and the core requirements of consumers on rich and intense taste cannot be met. Second, the water-based environment changes the volatility and absorption characteristics of free base nicotine, and thus its nicotine craving for satisfaction and bioavailability are greatly compromised, and users may need to draw more frequently and deeply to obtain satisfaction. Finally, the solution may be suitable for only a few tobacco tar with specific flavor, but cannot be used as a general platform to adapt to complex essence types on the market, so that the potential of commercial application of the solution is greatly limited. Disclosure of Invention The invention mainly aims to provide an aerosol generating substrate, a preparation method and application thereof, and aims to solve the problem of aerosol generation in the existing electronic cigarette tobacco tar atomization process. To achieve the above object, the present invention proposes an electronic aerosol-generating substrate comprising the following raw material components: nicotine, cooling agent, sweetener, essence, colloid, surfactant and compound solvent, wherein the compound solvent is water and medium short-chain alcohol. In one embodiment, the mass ratio of the medium and short chain alcohol to the water is 1.0:1.4-1.0:3.6, and/or, The water mass ratio is not more than 60% of the mass of the aerosol-generating substrate, and/or, The medium short chain alcohol comprises at least one of ethanol, n-propanol, isopropanol, n-butanol and isobutanol. In one embodiment, the composition comprises the following components in parts by weight: 1-20 parts of nicotine; 1-5 parts of cooling agent; 1-5 parts of sweetener; 5-20 parts of essence; 0.1-2 parts of colloid; 1-5 parts of a surfactant; 20-45 parts of medium short chain alcohol and 40-60 Parts of water. In one embodiment, the aerosol-generating substrate comprises the following components in parts by mass: 3-12 parts of ni
