Cigarette composite filter material and preparation method thereof

Abstract

Disclosed are a cigarette composite filter material and a preparation method therefor. The components of the composite filter material comprise: 80-90 parts by weight of modified active clay and 7-15 parts by weight of a binder, as well as 0.5-1.5 parts by weight of barium sulfate and 2-4 parts by weight of diatomite. The cigarette composite filter material of the present invention can selectively adsorb harmful substances in cigarette smoke, has a high adsorption capability, and can reduce the hazard of cigarette to the maximum degree, while keeping the flavor and characteristics of the cigarette.

Description

technical field [0001] The invention relates to a filter material and a preparation method thereof, in particular to a composite filter material for cigarettes and a preparation method thereof. Background technique [0002] my country is the country with the largest number of smokers in the world and the largest consumption of cigarettes. According to statistics, there are more than 320 million smokers. Smoking is very harmful to the human body, not only that, second-hand smoke is no less harmful to non-smokers than smokers. With people's emphasis on health, and advanced countries and the United Nations Health Organization's increasingly high requirements for my country to solve the problem of cigarette tar content exceeding the standard, our country will face pressure from both at home and abroad. Huge human and financial resources have been invested, but real results have not yet been seen. [0003] At present, tar, nicotine, and CO are used internationally to evaluate th...

[0007] 3. Add activated carbon to the cotton acetate fiber filter. This method should be the most effective method for reducing coke and harm, because activated carbon is a very effective adsorbent. At this stage, most foreign brand cigarettes use this method to reduce coke, but domestic It is not used in large quantities, the main reason is that the adsorption capacity of activated carbon is too strong and non-selective, the effect cannot be achieved by adding less, and ventilation technology should be added to match, and the addition of too much will reduce the tar and also absorb nicotine ( nicotine) and aromatic substances, which make cigarettes tasteless and tasteless, and change the original characteristics and flavors of cigarettes of various brands, making it difficult to attract smokers to buy
