Description
Technical Field
The invention relates to the technical field of cigarette filter sticks, in particular to a binary composite filter stick for reducing the release amount of heavy metal in main stream smoke of cigarettes.
Background
Along with the improvement of living standard, the health consciousness and the environmental protection consciousness of consumers are gradually enhanced, and cigarette consumers pay more and more attention to the smoking safety of cigarettes. Therefore, the development of low-harm cigarette products is receiving extensive attention.
Toxic heavy metals such as arsenic, lead, chromium, cadmium, mercury, nickel and the like in the mainstream smoke can enter a human body in the form of aerosol or metal oxide and the like, and the toxic heavy metals are harmful to the human body after being accumulated to a certain degree. At present, the heavy metal elements are listed in the list of harmful components in cigarette smoke. In recent years, around the problems of heavy metal release and harm of cigarette smoke, industry researchers have proposed some harm reduction technologies to reduce the release amount of heavy metal in cigarette smoke. Among them, the adsorption and retention technology based on cigarette filter stick is one of the research hotspots. The adsorption and interception capacity of the common diacetate fiber tow section on heavy metals in smoke is limited, and the release amount of the heavy metals cannot be obviously reduced. Therefore, various functional materials such as activated carbon, molecular sieves, silica gel, chitosan, functional polymer adsorbents and the like are often added into the common filter stick, and the prepared composite filter stick can selectively absorb harmful ingredients (including heavy metals) in smoke, so that the safety of cigarettes is improved. For example, patent CN103071454A describes an additive for a seaweed activated carbon filter, and a composite filter prepared by using the activated carbon can obviously reduce the release amount of heavy metals such as chromium, nickel, arsenic, cadmium, lead and the like in mainstream smoke, and has the special flavor of seaweed. Patent CN203748660U has designed a compound aluminum bar that contains heavy metal filter segment, and the filter segment contains fibre silk bundle and distributes the mesoporous titanium dioxide composite material granule on the silk bundle, and this kind of novel compound filter rod can reduce cigarette smoke heavy metal release volume under the condition of guaranteeing original taste of cigarette and smoking quality. CN103506092A prepares a load type polyamide-amine dendritic polymer adsorbent, and after the adsorbent is used for a cigarette composite filter stick, only a small amount of the adsorbent needs to be added, so that the adsorbent has a large adsorption capacity and a strong adsorption capacity for heavy metals in smoke. CN109259304A discloses a tobacco baked aromatic filter tip which can remarkably reduce the heavy metal content in cigarette smoke. CN103113686A takes ion exchange resin as the filter stick additive material to prepare a binary composite filter tip, and the filter tip can obviously reduce the release amount of heavy metals such as chromium, nickel, arsenic, cadmium, lead and the like in the mainstream smoke and reduce the harm to human bodies. CN102440436A makes chitosan fiber tow into adsorption line, and the cigarette filter stick is prepared by using water-soluble chitosan as adhesive, the adsorption rate of the filter stick to heavy metal substances in smoke can reach 20-30%, the content of heavy metal substances absorbed into the body is remarkably reduced, and the operability of large-scale production is realized. CN102499479A takes silica gel, alumina, molecular sieve or cellulose acetate as a carrier, obtains a complexing adsorbent by loading natural amino acid, and the binary composite filter stick prepared by adding the complexing adsorbent into a cigarette filter stick can effectively reduce the heavy metals of cadmium in the mainstream smoke of cigarettes by 15-40% and arsenic by 5-20%, and does not influence the smoking taste of the cigarettes.
Although the research results of the patents show a better reduction effect of heavy metals in cigarette smoke, the research results also have some defects. For example, the active carbon and the mesoporous composite material have no adsorption selectivity to smoke components, and can adsorb cigarette fragrance components while reducing the content of harmful components of cigarettes, so that the smoking taste of the cigarettes is deteriorated; the preparation process of the dendritic functional polymer adsorbent and the amino acid supported complex adsorbent is complicated and the cost is high.
Researches show that the safe natural renewable biological material with better biodegradability is a novel material with great research value, and the research and development of the material for reducing the harm of the cigarettes based on the natural renewable biological material have extremely high market popularization prospect. For example, patent 201520541130.6 reports that a composite cigarette filter stick containing soy protein polypeptide can effectively reduce cigarette irritation, coordinate smoke, and improve aftertaste.
Collagen is a natural biological macromolecule, widely exists in animal bones and skins, is a common animal biomass resource, is safe and renewable, and has proper price. The molecular structure of the collagen contains a large number of polar groups such as peptide bonds, amino groups, carboxyl groups, hydroxyl groups and the like, and the existence of the groups is helpful for the collagen to carry out complexation adsorption and removal on heavy metals in cigarette smoke. Meanwhile, the adsorption capacity of the collagen to harmful ingredients in the cigarette smoke can be improved by adding a proper amount of porous activated carbon for recombination. So far, no report of a binary composite filter stick for reducing the heavy metal release amount of cigarette smoke by simultaneously adding collagen and activated carbon into diacetate fibers is found at home and abroad.
