preparation example Construction

[0021] A method for preparing functional cigarette paper as described above, the preparation method is: first complete the manufacture of cigarette paper on a paper machine, introduce a spray device after the point where the combustion regulator of the paper machine is added, and prepare molecular encapsulation materials into ingredients asco-encapsulated adsorbent solution, and the solution is evenly sprayed on the cigarette paper, and then dried by a drying cylinder; The cigarette paper is uniformly dip-coated on the coating machine, and then dried in a low-temperature drying cylinder. The temperature of the drying cylinder is controlled between 60-80°C until the alcohol is completely volatilized; The mass percentage is 1-20%.

[0022] The preparation process of the molecular encapsulation adsorbent alcohol solution is as follows: prepare a wall material solution with a mass percentage of 40-80%, add a solid adsorbent with a mass percentage of the wall material solution ...

Abstract

The invention provides functional cigarette paper and a preparation method. The functional cigarette paper comprises common cigarette paper prepared by using a paper making process, and the surface of the common cigarette paper is sprayed or dip-coated with a molecular capsulation material layer capable of reducing the contents of harmful substance, such as carbon monoxide, nitrosamine and the like in cigarette smoke. The preparation method comprises following steps of: finishing making of cigarette paper on a paper making machine, introducing a spraying device at the back of a combustion adjusting agent feed point of the paper making machine, preparing a molecular capsulation material into a molecular capsulation adsorbent solution, uniformly spraying the solution on the cigarette paper, and drying by a drying tank; or after finishing the making of the cigarette paper, preparing the molecular capsulation material into a molecular capsulation adsorbent alcohol solution, and uniformly dip-coating the solution to the cigarette paper on a coating machine, and then drying through a low-temperature drying cylinder until the alcohol fully volatilizes; and the addition amount of the molecular capsulation absorbing agent accounts for 1-20% of the mass percentage of the weight of the cigarette paper. The preparation method has the characteristics of simple molecular capsulation process, convenience for addition of the absorbing agent, and capability of reducing the content of harmful substances, such as carbon monoxide, nitrosamine and the like, in the cigarette smoke.

Description

technical field [0001] The invention relates to a functional cigarette paper, in particular to a functional cigarette paper which uses a molecular capsule adsorbent to reduce the content of harmful substances such as carbon monoxide and nitrosamines in cigarette smoke and a preparation method thereof. Background technique [0002] In 2005, the "Framework Convention on Tobacco Control" (FCTC) came into effect in my country. The convention requires governments of all countries to formulate corresponding regulations to more strictly limit the release of harmful components (Hoffmann analytes) in cigarette products. In recent years, the industry has done a lot of work in the field of cigarette harm reduction technology research and application, and has achieved certain results. It has established analysis and test methods for 44 kinds of harmful components in cigarette smoke that are internationally concerned, and developed a batch of cigarette smoke that reduces the harmf...
