Problems solved by technology

Through the blocking and adsorption of solid substances, tar and other harmful substances can be reduced at the same time, but the effect is not so obvious when applied to medium and low tar cigarettes. The reduction of tar is higher than the reduction of harmful substances, and high selectivity cannot be achieved. Requirements for Reducing Harmful Components in Cigarette Smoke
Moreover, these patented technologies involve problems such as complex processes, safety of active components, and high cost, so there are certain difficulties in application prospects.

Embodiment 1

[0031] Freshly prepared calcium alginate: Take 5g of sodium alginate, sprinkle it evenly into 100g of distilled water, and stir in a water bath at 55°C and 300r / min for 45min to form an aqueous solution of sodium alginate. Use a syringe with a needle diameter of 2.5 mm to drop the above solution into 300 ml of calcium chloride aqueous solution with a mass fraction of 10%, let it stand for 1 hour, take out the solid particles, filter with suction, and wash with water to obtain fresh calcium alginate for later use.

[0032] At 40°C, use ethanol as a solvent to prepare 9g of rosin solution with a mass fraction of 20%; at normal temperature, use water as a solvent to prepare 2g of sodium lauryl sulfate solution with a mass fraction of 10%, and Requirements, pour into the rosin solution and keep it for 4 hours.

[0033] Weigh 426g of freshly prepared calcium alginate (the actual calcium alginate content is 100g), slowly add the solution into the freshly prepared calcium alginate, s...

Embodiment 2

[0036] The freshly prepared calcium alginate method is the same as in Example 1.

[0037] At 40°C, with ethanol as a solvent, prepare 22.5g of rosin solution with a mass fraction of 20%; Than requirements, pour into the rosin solution, keep for 4 hours.

[0038] Weigh 426g of freshly prepared calcium alginate (the actual calcium alginate content is 100g), slowly add the solution into the freshly prepared calcium alginate, stir evenly at the same time, soak for 0.5 hours to make it fully infiltrated; move the wet particles into the infrared lamp to dry for 4 hours, and make the material Fully react and dry, cool naturally to room temperature, sieve to remove fine powder and take 40-60 mesh particles for use.

[0039] The prepared additive was added to the tow of the cigarette filter at 40mg / piece, and the cigarette without the additive in the filter was used as the control smoke. The smoke test results showed that the material could effectively reduce the ammonia content in th...

Embodiment 3

[0041] The freshly prepared calcium alginate method is the same as in Example 1.

[0042]At 40°C, using ethanol as a solvent, prepare 25g of a rosin solution with a mass fraction of 20%; weigh 426g of fresh calcium alginate (the actual calcium alginate content is 100g), slowly add the solution to the fresh calcium alginate, and stir evenly at the same time. Soak for 0.5 hours to make it fully infiltrated; move the wet granules into the infrared lamp and dry for 4 hours to fully react and dry the materials, cool to room temperature naturally, sieve to remove fine powder and take 40-60 mesh granules for use.

[0043] The prepared additive was added to the tow of the cigarette filter at 40mg / piece, and the cigarette without the additive in the filter was used as the control smoke. The smoke test results showed that the material could effectively reduce the ammonia content in the smoke by 2.7% compared with the control group , The tar removal rate was 0.8%.

Abstract

The invention discloses a cigarette filter stick additive with a function of reducing ammonia release amount in cigarette mainstream smoke, and a preparation method and application thereof. The cigarette filter stick additive comprises an active component consisting of lauryl sodium sulfate and rosin, and a particle carrier for loading the active component. When the cigarette filter stick additive is added into cigarette filter stick tows, the content of ammonia in mainstream smoke can be effectively reduced by 10-28.5%, and the content of tar is hardly reduced; and the preparation method of the cigarette filter stick additive is simple, low in cost and convenient for industrial mass production.

Description

technical field [0001] The invention relates to a functional cigarette filter rod additive, in particular to a functional additive composed of sodium lauryl sulfate and rosin active components, and also relates to the addition of the functional additive to the cigarette filter rod to reduce the release of ammonia in the mainstream smoke of cigarettes The application of the invention belongs to the technical field of cigarette preparation. Background technique [0002] Ammonia is colorless and has a strong pungent smell. It can burn the skin, eyes, and mucous membranes of respiratory organs. If people inhale too much, it can cause lung swelling and even death. It is a toxic substance, and the increase of blood ammonia is the most obvious damage to the brain nerve tissue. It is one of the main harmful substances in flue gas. The content of ammonia in fresh tobacco leaves is very small, and the content of ammonia increases due to the metabolism of proteins and amino acids (ox...
