Embodiment 1

[0032] Cigarette paper produced by the above technology can significantly reduce carbon monoxide, nitrogen oxides and phenolic substances in cigarette smoke when used in cigarette production. The examples are as follows:

[0033] 1. Preparation of inner cigarette paper:

[0034] 1.1 Beat the long and short fibers for papermaking according to a certain ratio, adjust the beating degree, add 15% calcium carbonate, and make the air permeability of the cigarette paper 120 Coriolis units;

[0035] 1.2 Add the prepared nano-sized cuprous oxide, the addition amount is 6%, and add 1% of the combustion aid potassium citrate after molding;

[0036] 1.3 Adjust the basis weight of the inner cigarette paper to 16g / m 2 , According to the requirements of rolling and splicing, the cutting width is 24mm, and the inner layer of cigarette paper is ready.

[0037] 2. Preparation of outer cigarette paper:

[0038] 2.1 Beat the long and short fibers for papermaking according to a certain ratio, a...

Embodiment 2

[0043] 1. Preparation of inner cigarette paper:

Abstract

The invention relates to double-layer cigarette paper formed by an inner layer of cigarette paper wrapped outside tobacco shred, and an outer layer of cigarette paper wrapped outside the inner layer of cigarette paper. The inner layer of cigarette paper can be loaded with a catalyst which comprises a metallic oxide, a metallic compound oxide, a metallic hydroxide or a metallic oxide hydroxide, concretely relates to one or a plurality of the oxides, the compound oxides, the hydroxide or the oxide hydroxide of iron, manganese, copper, zinc, titanium, aluminum, calcium, cobalt, palladium, platinum, lanthanum, strontium or cerium and the like; the mass content of the catalyst accounts for 1 to 30 percent of the mass of the inner layer of cigarette paper, preferably 3 to 10 percent of the massof the inner layer of cigarette paper. The technique can effectively reduce the content of hazardous substances such as carbon monoxide, oxynitride and phenols and the like in the smoke of the cigarette.

Description

technical field [0001] The invention relates to a cigarette paper, in particular to a double-layer cigarette paper and a preparation method which can reduce the content of harmful substances such as carbon monoxide, nitrogen oxides and phenols in cigarette smoke by using a catalyst. Background technique [0002] Reducing the harm of cigarettes is an important research topic for the tobacco industry, and it will continue for a long time. Various tobacco research institutes have been working on the research of this work and have achieved gratifying results, but a large part of the results are still not applied, mostly due to the complexity of the smoke system and people's special smoking requirements for cigarettes. [0003] Cigarette paper is not just a wrapping material for tobacco, it also participates in the burning of cigarettes, affects the diffusion of smoke and changes the chemical composition of mainstream smoke. There is no doubt that the material composition and st...
