Embodiment Construction

[0015] The present invention utilizes the existing flexo printing technology to print two printing tapes on the front and back of the tipping paper at the same position simultaneously to form a flame-retardant tape. more) such a flame retardant tape. The intervals between the three fire-retardant belts are the same.

[0016] The material used for the inner flame retardant layer is cigarette flame retardant adhesive with low tendency to ignite. image 3 The shown flexo printing device simultaneously prints and coats both sides of the cigarette paper at the same position, and places cigarette flame-retardant adhesive with low ignition tendency and high thermal conductivity material at the troughs (9 and 10) of the two flexo printing devices respectively , roller A is coated on the inner layer of cigarette paper 4 to form a printing layer 6, and then dried quickly by drying equipment; and then the second flexo printing roller B is applied to the outer printing layer at the same ...

Abstract

The invention relates to cigarette paper with low ignition tendency and a preparation method thereof. At least one thermal conductive flame retardant belt is arranged on the cigarette paper which wraps shredded tobacco; and each flame retardant belt is formed by an inner layer and an outer layer, wherein the inner layer is coated with a flame retardant colloid and the outer layer is coated with a thermal conductive flame retardant material so that the inner layer and outer layer coated thermal conductive flame retardant belt is formed. When the ignited cigarette is burnt to the flame retardant belt and makes contact with a combustible, with the presence of the inner flame retardant layer, the cigarette paper is nonflammable and the temperature is reduced; at the same time, with the presence of the outer thermal conductive layer, the temperature transferred from a cigarette combustion cone to the cigarette paper can be delivered out rapidly so that the combustion tendency of the cigarette paper is further reduced and the possibility of igniting the combustible is reduced. The flame retardant cigarette paper disclosed by the invention can satisfy the requirements of the cigarettes with low ignition tendency, is low in cost, practical and efficient, and can effectively reduce the ignition tendency of the cigarettes.

Description

technical field [0001] The invention relates to the technical field of cigarettes, in particular to a cigarette paper with low ignition tendency and a preparation method thereof. Background technique [0002] With the development of tobacco technology, "smoking and safety" and "smoking and health" have become the mainstream trend in the development of the tobacco industry. Safety is mainly limited from two aspects: one is to reduce the damage and pollution to the human body and the environment caused by the smoke generated by burning cigarettes; the other is to "reduce the tendency to catch fire" and prevent fires caused by smoking. [0003] The center temperature of the cigarette butt is as high as 800-900°C, and its surface temperature is also 300-400°C, while the ignition point of general solid combustibles is around 200°C. Therefore, when the smoker is inadvertent or asleep, when the unextinguished cigarette falls on clothes, furniture or paper, it is very easy to cause...
