Embodiment 1

[0032] The oil phase is configured first, and the composition of the oil phase is 8ml of glycidyl methacrylate, 2ml of methyl methacrylate, 0.5ml of ethylene glycol dimethacrylate, and 5g of modifier-modified silica nanoparticles.

[0033] Configure the water phase, and mix 64ml of water and 0.5g of calcium chloride evenly to prepare the water phase.

[0034] Under high-speed stirring at 500 rpm, the water phase was slowly added to the oil phase to form a high internal phase emulsion, which was poured into a filter rod forming mold with a diameter of 7.7 mm and a length of 100 mm, and sealed with nitrogen gas for 10 minutes.

[0035] In the technical solution of the present application, the forming mold of the filter rod can be changed as required, such as a filter rod mold with a diameter of 7.0mm or 6.0mm or 5.4mm and a length of 100mm or 120mm or 144mm, or other types of molds. , The model of the filter rod mold does not affect the realization of the technical solution of t...

Embodiment 2

[0038] First configure the oil phase, the composition of the oil phase is 4ml glycidyl methacrylate, 0.5ml 2-ethylhexyl acrylate, 3ml trimethylolpropane trimethacrylate, 3g modifier modified silica nano particle.

[0039] Configure the water phase, mix 60ml of water and 0.5g of sodium chloride evenly to prepare the water phase.

[0040] Under high-speed stirring at 500 rpm, the water phase was slowly added to the oil phase to form a high internal phase emulsion, which was poured into a filter rod forming mold with a diameter of 7.0 mm and a length of 120 mm, and sealed with nitrogen gas for 10 minutes. Then put the mold with high internal phase emulsion into 1.3×10 15 Q 60In the Co source, the dose rate is 36Gy / min, and the irradiation time is 36h.

[0041] The resulting solid product was placed in excess propylenediamine solution at 40°C for 24 hours, extracted with water and ethanol for 24 hours, and dried in a vacuum oven to obtain the final filter rod.

Embodiment 3

[0043] The oil phase is configured first, and the composition of the oil phase is 5ml of glycidyl methacrylate, 2ml of methyl methacrylate, 1ml of glycerol tri(αˉmethacrylate), and 4g of modifier-modified silica nanoparticles.

[0044] Configure the water phase, mix 70ml of water and 1.5g of magnesium sulfate evenly to prepare the water phase.

[0045] Under high-speed stirring at 700rpm, slowly add the water phase into the oil phase to form a high internal phase emulsion, pour it into a filter rod forming mold with a diameter of 6.0 mm and a length of 120 mm, and seal it after passing nitrogen gas for 10 minutes.

[0046] Then put the mold with high internal emulsion into 1.3×10 15 Q 60 In the Co source, the dose rate is 36Gy / min, and the irradiation time is 36h.

[0047] The resulting solid product was placed in excess ethylenediamine solution at 50°C for 24 hours, extracted with water and ethanol for 24 hours, and dried in a vacuum oven to obtain the final filter rod.

Abstract

The invention relates to a preparation method of a novel filter stick capable of reducing the release amount of crotonaldehyde in smoke, which comprises the following steps: carrying out high internalphase emulsion polymerization in a specific filter stick mold, and reacting with an amination reagent to prepare the novel filter stick capable of reducing the release amount of crotonaldehyde in smoke. The novel filter stick can be directly formed into a filter stick with specific circumference and length in a filter stick forming die, has certain strength, and can meet the requirements of tipping cigarettes; macropores with micron sizes are formed in the filter stick, and the pores are communicated with one another, so that cigarette smoke can be conveyed; after an epoxy group reacts with an amination reagent, the filter stick has an amino functional group, so that the release amount of crotonaldehyde in flue gas can be reduced; silicon dioxide nanoparticles are used as a particle emulsifier, so that the strength of the filter stick can be improved; the particle emulsifier is modified by a modifier, and the modifier has polymerizable double bonds and is beneficial to high internal phase emulsion polymerization; a radiation polymerization method is adopted, no chemical initiator is added, and the disinfection and sterilization effects are achieved.

Description

technical field [0001] The invention belongs to the technical field of filter rod preparation, in particular to a method for preparing a novel filter rod capable of reducing the release of crotonaldehyde in flue gas. Background technique [0002] Crotonaldehyde is one of the main harmful components of cigarette mainstream smoke. The "Cigarette Hazard Index System Research" project studied the relationship between the release of harmful components and the biological activity of smoke, and found that crotonaldehyde is the most important factor affecting the harmfulness of cigarette mainstream smoke. Therefore, reducing the content of crotonaldehyde in cigarette smoke is of great significance for reducing the harmfulness of cigarettes. [0003] As for how to reduce crotonaldehyde in cigarette smoke, many related studies have been carried out at home and abroad. Patent CN104941606B discloses an adsorbent for reducing the release of crotonaldehyde in cigarette mainstream smoke, ...
