Problems solved by technology

[0004] However, the time for the smoke to pass through the filter is very short, and at the same time, the various components in the smoke are mixed together and pass through the filter in the form of aerosol. In addition to improving the taste or irritation, the existing additives cannot effectively remove harmful substances in the smoke , and the preparation process is complicated, so we consider using polymers including polyvinylpyrrolidone in additives

Abstract

The invention discloses a composite material capable of lowering the releasing amount of crotonaldehyde in cigarette gas and a preparing method and application thereof. The composite material is prepared from, by weight, 1-10 parts of polymers, 1-10 parts of hyamine, 1-10 parts of molecular sieves and 100 parts of solvent, wherein the polymers are polyvinyl pyrrolidone or vinyl pyrrolidone-maleicacid copolymer or both, wherein both the molecule weights of the polyvinyl pyrrolidone and the vinyl pyrrolidone-maleic acid copolymer are 1000-1000000. According to the composite material capable oflowering the releasing amount of crotonaldehyde in cigarette gas and the preparing method and application thereof, the polyvinyl pyrrolidone and the hyamine are mixed and subjected to precipitation composition on the surfaces of the molecular sieves, so that the contact area of the composite material and the cigarette gas is improved, then the adsorption efficiency and capacity of the crotonaldehyde in the cigarette gas are improved, and the composite material can rapidly and selectively lower the crotonaldehyde content in the cigarette gas, does not have obvious influence on the smoking smellof cigarettes, and improves the irritation.

Description

technical field [0001] The invention relates to a composite material, in particular to a composite material for reducing the emission of crotonaldehyde in smoke, and also relates to a preparation method and application thereof, belonging to the field of tobacco. Background technique [0002] Dozens of harmful substances have been identified in tobacco and smoke. Cigarette smoke irritates the respiratory tract and eyes, and long-term smoking may induce related diseases. Crotonaldehyde is one of the main volatile carbonyl compounds in mainstream cigarette smoke. It is a respiratory cilia toxin that strongly stimulates the conjunctiva and upper respiratory tract mucosa. Long-term inhalation can easily cause chronic rhinitis and nervous system dysfunction. In 1990, D.Hoffman and S.S.Hecht summarized the main harmful components of smoke in the book "Research Progress on Tobacco Carcinogens and Mutagens", and listed 12 categories with a total of 43 harmful components, commonly kno...
