Embodiment 1

[0021] Preparation of inorganic fiber filter material. Weigh 0.5 parts of kaolin, 5 parts of limestone, 60 parts of quartz sand, 0.5 parts of borax, 0.2 parts of fluorite, 2 parts of nitrate and 1 part of titanium dioxide. Mix the raw materials evenly, crush the mixture to 100 mesh, and then heat it in a high-temperature furnace to 1100°C to melt. The molten material is drawn into ultra-fine wires with a diameter of 0.2 μm and a length of 2 mm through a spinning device, and the ultra-fine wires are softened. Rolled into particles with a diameter of 0.5mm, which is the required inorganic fiber filter material.

Embodiment 2

[0023] Preparation of inorganic fiber filter material. Weigh 2.5 parts of kaolin, 10 parts of limestone, 75 parts of quartz sand, 1 part of borax, 0.6 parts of fluorite, 4 parts of nitrate and 1.5 parts of alumina. Mix the raw materials evenly, crush the mixture to 250 mesh, and then heat it in a high-temperature furnace to 1300°C to melt. The molten material is drawn into ultra-fine wires with a diameter of 0.5 μm and a length of 3.5 mm through a spinning equipment, and the ultra-fine wires are softened. After rolling, it is made into particles with a diameter of 0.8mm, which is the required inorganic fiber filter material.

Embodiment 3

[0025] Preparation of inorganic fiber filter material. Weigh 5 parts of kaolin, 15 parts of limestone, 90 parts of quartz sand, 2 parts of borax, 1 part of fluorite, 6 parts of nitrate and 2 parts of magnesium silicate. Mix the raw materials evenly, crush the mixture to 400 mesh, and then heat it in a high-temperature furnace to 1500°C to melt. The molten material is drawn into ultra-fine wires with a diameter of 0.8 μm and a length of 5 mm through a spinning device, and the ultra-fine wires are softened. Rolled into particles with a diameter of 1.0mm, which is the required inorganic fiber filter material.

Abstract

The invention discloses an inorganic fiber filtration material and a preparation method and an application thereof. In the method, uniform mixing, grinding, melting, laddering and softening are carried out on 0.5-5 parts of kaolin clay, 5-15 parts of limestone, 60-90 parts of quartz sand, 0.5-2 parts of borax, 0.2-1 part of fluorite, 2-6 parts of mirabilite and 1-2 parts of trace mineral supplement; then the mixture is rolled and prepared into particles with diameter ranging from 0.5mm to 1.0 mm. The method and application of the invention are safe in use and absorption effect thereof is superior to the absorption effect of the traditional material; in addition, the method and the application can noticeably reduce special injurious ingredients such as benzo(alpha)pyrene, 4-(methyl nitrosamino)-1-(3-pyridyl)-1-butanone(NNK), phenol and the like in cigarette smoke; In addition, harm caused by smoking is reduced and mouthfeel of the cigarette is only slightly affected; the preparation technique of the invention is simple, the use thereof is convenient and realization of industrialized production is easy.

Description

technical field [0001] The invention belongs to the technical field of cigarette harm reduction, and in particular relates to an inorganic fiber filter material capable of absorbing harmful components in cigarette smoke. At the same time, the invention also relates to a preparation method of the fiber material and a specific application in cigarettes. Background technique [0002] With the formal entry into force of the Framework Convention on Tobacco Control in my country, the tobacco industry is facing further pressure on smoking and health issues. Chinese scientific and technological workers have also strengthened the research on the special harmful components of cigarette smoke. Recently, the State Tobacco Monopoly Administration organized a study of 29 harmful substances and 4 toxicological indicators of 163 domestic and foreign cigarettes, using data mining techniques such as genetic algorithm and non-informative variable deletion method, and found that only CO, HCN, ...
