Example Embodiment

[0018] Example 1

[0019] Zinc oxide powder additive was added to the foaming agent azodicarbonamide (thermal decomposition temperature 195°C), mixed evenly, and the thermal decomposition temperature was lowered to 160°C, which was used in the papermaking test. Use a cigarette paper air permeability tester to test the air permeability of the paper. The test process for the change of air permeability before and after heating the paper is as follows: mark the test position when testing the air permeability of the paper for the first time, and heat the paper at 170-230 ° C for 1-5 min. The quasi-mark again tests the air permeability of the position. Select more than 5 points to test the same sample, and the test results are shown in Table 1.

Example Embodiment

[0020] Example 2

[0021] According to the laboratory papermaking test, the change of air permeability of paper before and after heating, soaking and beating the weight of long fibers and short fibers in a ratio of 1:2, adding 30% calcium carbonate, guar gum and the content of the mass of the paper made 5% blowing agent azodicarbonamide, papermaking, drying. Use a cigarette paper air permeability tester to test the air permeability of the paper. The test method is the same as in Example 1, and the test results are shown in Table 1.

Example Embodiment

[0022] Example 3

[0023] The weight of long fibers and short fibers is 1:2, soaking, beating, guar gum and basic zinc carbonate accounting for 8% of the mass of the paper, making paper, and drying. Use a cigarette paper air permeability tester to test the air permeability of the paper. The test method is the same as in Example 1, and the test results are shown in Table 1.

[0024] Table 1 Comparison of changes in air permeability before and after heating of laboratory paper (1)

[0025] Air permeability change Δcu

[0026] It can be seen from Table 1 that after adding the foaming agent azodicarbonamide or basic zinc carbonate, the air permeability of the cigarette paper increases significantly after heating, reaching 9.37% and 14.63%, respectively.

Abstract

The invention provides cigarette paper with changeable air permeability, wherein, the adding particle is a foaming agent particle with the particle diameter of 0.1 micron to 10 micron, the air permeability of the cigarette paper with about 1 to 10 mm behind the carbonization line of the cigarette paper can be improved during the burning process of the cigarette, and thus the quantity of the air intake from the cone-shaped burning part is increased during the cigarette smoking process to achieve the effects that the burning condition is improved, the content of CO in the fume is reduced, and the tar intake quantity of the human body is decreased. The processing and preparing process of the cigarette paper with changeable air permeability of the invention are simple, the prior production process is not required to be changed, and the invention is suitable for popularizing in application.

Description

technical field [0001] The invention relates to a cigarette paper, in particular to a cigarette paper whose air permeability increases during combustion. Background technique [0002] The air permeability of cigarette paper directly affects the combustibility of cigarettes, and also affects the amount of air entering the cigarette from the vicinity of the combustion cone and the dilution of cigarette smoke, thereby affecting the tar intake of the human body when smoking cigarettes. Therefore, improving the air permeability of cigarette paper is of great significance for improving the combustibility of cigarettes, improving the dilution of cigarette smoke, and controlling the intake of tar in the human body. [0003] The harmful substances in the mainstream smoke decrease with the increase of the air permeability of the cigarette paper. In addition to diluting the smoke in the cigarette stick, the high air permeability cigarette paper can also increase the burning speed and c...
