Embodiment 1

[0023] 1Kg hydrophilic SiO 2 The nanoparticles were calcined at 500 °C for 5 h to increase the SiO 2 The Si-OH content on the surface of the nanoparticles was placed in a closed reactor after cooling, and the SiO was slowly heated under the protection of nitrogen. 2 Nanoparticles to 150 ° C and keep the temperature constant, feed SiO into the closed reactor 2 Trimethylchlorosilane with 10% weight of nanoparticles, stop heating after reacting for 6h, naturally cool to room temperature, wash with ethanol, and then dry, the resulting product is trimethylchlorosilane modified nano-SiO 2 particles, i.e. hydrophobic nano-SiO 2 particle. nano-SiO 2 The specific surface and pore structure data of particles before and after modification are shown in Table 1 below. Hydrophilic and hydrophobic nano-SiO 2 The TEM image of the particle is shown in the figure.

Embodiment 2

[0030] Before cigarette, the hydrophobic nano SiO that embodiment 1 makes 2 The particles are added to the tobacco feed liquid at a ratio of 1.0% by weight of the tobacco leaves, stirred evenly, added to the tobacco leaves together with the feed liquid, and then other processes of cigarette processing are performed.

Embodiment 3

[0032] When the papermaking method is used to produce reconstituted tobacco leaves, the hydrophobic nano-SiO obtained in Example 1 2 The particles are added to the slurry or dipping coating at a ratio of 2.0% by weight of the tobacco leaves, and then fully stirred to fully disperse the nanomaterials in the slurry or dipping coating, and then enter the process of making, drying, chipping, etc. with the slurry or dipping coating The processing procedure of reconstituted tobacco leaves, and finally add the reconstituted tobacco leaves to the tobacco leaf formula in proportion to produce cigarettes.

Abstract

The invention discloses a selective harm-reducing cigarette and a preparation method thereof. Smoke generated after the cigarette burns contains the components including phenol, crotonic aldehyde and CO. The selective harm-reducing cigarette is characterized in that cut tobacco for preparing the cigarette, reconstituted tobacco or cut stem contains surface hydrophobing SiO2 nanoparticles capable of reducing contents of smoke phenol and the crotonic aldehyde, and the surface hydrophobing SiO2 nanoparticles account for 0.5-10% of the weight percent of the cut tobacco, the reconstituted tobacco or the cut stem. The hydrophobing SiO2 nanoparticles are formed by modifying hydrophilic SiO2 nanoparticles roasted at high temperature through trimethylchlorosilane. The selective harm-reducing cigarette can restrain 27.2% of the phenol and 12.4% of the crotonic aldehyde in main stream smoke.

Description

technical field [0001] The invention relates to the field of cigarette manufacturing and processing, and relates to a selective harm-reducing cigarette obtained by selectively reducing the content of harmful components such as phenol and crotonaldehyde in smoke and a preparation method thereof. Background technique [0002] Cigarette smoke has a complex composition and contains thousands of compounds, some of which are harmful to human health. Nanomaterials have attracted the attention of researchers in the field of smoke hazard reduction due to their large specific surface area and high adsorption activity. However, most of these studies focus on the reduction of tar content in cigarette smoke by nanomaterials. In fact, "tar reduction" does not mean "harm reduction". Simple tar reduction can easily cause the loss of flavor components in tar and reduce cigarette smoking. quality. Therefore, only by selectively reducing the content of harmful components in cigarette smoke c...
