Abstract

A low-tar combustible matrix used for cigarettes, comprises carbon, carbohydrate, other combustible mattes, ash elements, the mass parts of which are 1-30, 0-30, 0-30, 0-30, respectively. The combustible matrix of the invention contains a very low amount of hydrogen, hence, tar (tar contains hydrogen) produced after combustion is markedly decreased, which is helpful to protect smoker’s health.

Description

Low tar combustible substrate for cigarettes

The present invention relates to shredded tobacco, in particular to a low tar combustible substrate for cigarettes, which is used to make low tar cigarettes in place of combustible ingredients in natural shredded tobacco. Background technique

It is well known that cigarettes made from natural shredded tobacco produce tar which is harmful to the human body when inhaled. The prior art discloses a "cigarette made of composite structure shredded tobacco" (Patent No. ZL 01 2 59303.6) in which the composite structure cut tobacco is composed of a combustible substrate and a functional matrix adhered thereto. The flammable substrates are made of artificial or natural fibrous materials, but these materials produce higher levels of tar during combustion and are harmful to humans. There is therefore a need for a low tar combustible substrate. Summary of the invention

SUMMARY OF THE INVENTION It is an object of the present invention to provide a low tar combustible substrate for use in cigarettes to reduce the damage to the health of the consumer.

In order to achieve the above object, the technical solution adopted by the present invention is as follows: The low tar combustible substrate is composed of carbon quality, carbohydrates, other combustible materials, and ash elements, and the mass fractions are 1-30, 0-30, 0- respectively. 30, 0-30. among them:

Carbon quality: Since the formation of tar requires the presence of hydrogen, the proportion of carbon without hydrogen is greatly increased, which is conducive to the reduction of tar. The carbon quality is made into nano-scale carbon fiber, carbon fiber, carbon powder, carbon particles, and special shape carbon. One or a mixture of two or more of a film, a tube, or the like. These carbons can be mixed in various forms to match each other to improve combustion characteristics.

The low tar combustible matrix component may contain a certain amount of carbohydrates and other combustible materials. The carbohydrate compound includes one or a mixture of two or more of CnH2nOn (n = 2-5), glucose, fructose, sucrose, maltose, dextrin, starch, cellulose and other carbohydrates.

The other combustible materials include one or a mixture of two or more of hydrocarbon fuel hydrocarbons and other non-carbohydrate combustible organic materials and inorganic combustible materials. Carbohydrates and other combustibles are added to improve combustion characteristics and reduce costs.

The ash element includes one or a mixture of two or more of a salt or a compound of potassium, magnesium, calcium, chlorine, selenium, sodium, silicon, iron, carbonic acid, sulfuric acid, nitric acid, and other elements. The role of ash elements is to improve combustion characteristics and regulate combustion temperatures.

Compared with the prior art of combustible substrates, the tar content is much lower, which is beneficial to protect the health of smokers.

The present invention will be further described below in conjunction with the embodiments. detailed description
