Problems solved by technology

However, the particle size used in this patent is 0.05-1mm, which is larger than the general thickness of cigarette paper, resulting in thickened paper, uneven paper and easy powder loss. At the same time, the thermal decomposition speed of the pyrolyzable filler particles is slow, The actual effect is not good

Embodiment 1

[0019] Add zinc oxide powder additive to the foaming agent azodicarbonamide (thermal decomposition temperature 195°C), mix well, reduce the thermal decomposition temperature to 160°C, and apply it to the papermaking test. The air permeability of the paper was tested with a cigarette paper air permeability tester. The air permeability change test process of the test paper before and after heating is as follows: mark the test position when testing the air permeability of the paper for the first time, heat the paper at 170-230°C for 1-5 minutes, and test the air permeability of the paper after heating. The quasi-mark retests the air permeability of the position. For the same sample, select more than 5 points for testing, and the test results are shown in Table 1.

Embodiment 2

[0021] Through the laboratory papermaking test, the air permeability of the paper before and after heating is changed. The weight of long fibers and short fibers is soaked and beaten in a ratio of 1:2, and 30% calcium carbonate, guar gum and the mass content of the paper are added. 5% foaming agent azodicarbonamide, paper making, drying. The air permeability of the paper was tested with a cigarette paper air permeability tester. The test method is the same as in Example 1, and the test results are shown in Table 1.

Embodiment 3

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

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

[0025] Air permeability change Δcu

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