Description
技术领域technical field
本发明涉及一种可去除卷烟主流烟气中醛类物质的卷烟滤嘴添加剂及其制备方法和应用，属于卷烟滤嘴的制备技术领域。The invention relates to a cigarette filter additive capable of removing aldehydes in mainstream smoke of cigarettes, a preparation method and application thereof, and belongs to the technical field of cigarette filter preparation.
背景技术Background technique
卷烟烟气是卷烟在抽吸过程中产生的一个非常复杂的化学体系，至今为止已经被鉴定出来的化学成分有4000多种，其中有部分化学成分对人体和环境都是不利的，主要包括一氧化碳、氢氰酸、挥发性醛、氨、亚硝氨、苯并芘和酚类物质等。卷烟烟气气相成分中已发现的醛类物质已达20余种，其中含量最高的是甲醛、乙醛、丙醛、丙烯醛、巴豆醛和糠醛，这些挥发性的醛类物质尤其是甲醛、丙烯醛和巴豆醛是呼吸道纤毛的毒素，可导致肺部疾病。其中，巴豆醛更是在2008年被国家烟草专卖局列为卷烟主流烟气中七种有害成分之一。Cigarette smoke is a very complex chemical system produced during the smoking process of cigarettes. There are more than 4,000 chemical components that have been identified so far, some of which are harmful to the human body and the environment, mainly including carbon monoxide. , hydrocyanic acid, volatile aldehydes, ammonia, nitrosamines, benzopyrene and phenols, etc. More than 20 kinds of aldehydes have been found in the gas phase components of cigarette smoke, among which the highest content is formaldehyde, acetaldehyde, propionaldehyde, acrolein, crotonaldehyde and furfural. These volatile aldehydes are especially formaldehyde, Acrolein and crotonaldehyde are toxins of airway cilia and can cause lung disease. Among them, crotonaldehyde was listed as one of the seven harmful components in mainstream cigarette smoke by the State Tobacco Monopoly Administration in 2008.
为了降低卷烟对消费者健康的危害，提高卷烟的可食安全性，国内外烟草行业的很多专家一直致力于卷烟的减害研究，其中在去除卷烟主流烟气中醛类物质的报道也不少。报道最多的用于去除卷烟主流烟气中醛类物质的添加剂有活性炭，离子交换树脂，聚乙烯亚胺等等，其中活性炭的研究最为全面，英美烟草集团、布朗威廉姆森公司、菲莫公司等国外一些大的烟草公司均进行了大量的研究和实验论证，且美国、日本等国家的卷烟产品中有应用了活性炭的产品。活性炭对卷烟烟气的吸附过滤性能非常好，但选择性差，因此直接将活性炭应用于卷烟中将会给卷烟吸味带来负面影响，易导致产品质量降低。国内在这方面的探索研究也不少，CN102058159公开了用氧化亚铜改性的活性炭在卷烟滤棒中的应用，CN1692848公开了降Ti-Pd-Cu基活性炭纤维制备复合嘴棒，CN9010729公开了将活性炭加入嘴棒对卷烟烟气的影响。国内外的大部分研究显示活性炭以及其它改性的碳材料在卷烟滤嘴中应用，对卷烟烟气的焦油降低效果明显，但选择性不强，且对卷烟的吸味影响较大，导致其应用受到局限。In order to reduce the health hazards of cigarettes to consumers and improve the edible safety of cigarettes, many experts in the tobacco industry at home and abroad have been committed to the research of cigarette harm reduction, and there are many reports on the removal of aldehydes in mainstream cigarette smoke . The most reported additives used to remove aldehydes in mainstream cigarette smoke include activated carbon, ion exchange resin, polyethyleneimine, etc. Among them, activated carbon is the most comprehensive research, British American Tobacco Group, Brown Williamson, Philip Morris Some large foreign tobacco companies have conducted a lot of research and experimental demonstrations, and there are products using activated carbon in the cigarette products of the United States, Japan and other countries. Activated carbon has very good adsorption and filtration performance on cigarette smoke, but its selectivity is poor. Therefore, directly applying activated carbon to cigarettes will have a negative impact on the taste of cigarettes and easily lead to a decrease in product quality. There are also many domestic explorations and studies in this area. CN102058159 discloses the application of cuprous oxide modified activated carbon in cigarette filter rods. CN1692848 discloses the preparation of composite nozzle rods from Ti-Pd-Cu based activated carbon fibers. CN9010729 discloses Effects of adding activated carbon to mouth sticks on cigarette smoke. Most studies at home and abroad have shown that the application of activated carbon and other modified carbon materials in cigarette filters has a significant effect on reducing the tar in cigarette smoke, but the selectivity is not strong, and it has a greater impact on the taste of cigarettes, resulting in its Applications are limited.

本发明的有益效果：活性炭材料来源广泛，现有技术中的有采用活性炭或改性活性炭材料作为有害成分吸附剂用于卷烟滤棒的报道，但是这些炭材料的应用存在一个普遍的问题是，对烟气中各成分都具有吸附能力，导致卷烟吸味变化，并且会带来异味，影响卷烟的质量，无法实现对烟气中的某种成分进行选择性吸附，这成了炭材料作为吸附材料在卷烟中应用的一个难以攻克的技术瓶颈。本发明申请采用黏胶类物质将碳材料与烟草材料复合，完全解决了碳材料作为降害吸附剂在卷烟中应用存在的缺陷，一方面烟草材料参与复合有效改变了碳材料的表面结构，使吸附性能得到改变，使其具有选择性吸附醛类化合物的功能(对醛类化合物降低明显，特别是对甲醛和巴豆醛的选择性降低率超过30％)，而对焦油、烟碱、水和一氧化碳等吸附性能基本不体现；另一方面烟草材料补充适量烟草香味，而使卷烟感官品质基本保持平衡。另外，本发明的复合材料及滤嘴制备方法简单，成本低，满足工业化生产。Beneficial effects of the present invention: activated carbon materials have a wide range of sources, and there are reports in the prior art that activated carbon or modified activated carbon materials are used as harmful component adsorbents for cigarette filter rods, but there is a common problem in the application of these carbon materials. It has the ability to adsorb various components in the smoke, which will lead to changes in the taste of cigarettes, and will bring peculiar smells, affect the quality of cigarettes, and cannot achieve selective adsorption of certain components in the smoke. This has become a carbon material as an adsorption A difficult technical bottleneck in the application of materials in cigarettes. The application of the present invention uses adhesive substances to compound carbon materials and tobacco materials, which completely solves the defects in the application of carbon materials in cigarettes as harm-reducing adsorbents. On the one hand, the participation of tobacco materials in compounding effectively changes the surface structure of carbon materials, making The adsorption performance is changed, so that it has the function of selectively adsorbing aldehyde compounds (remarkably reduced to aldehyde compounds, especially the selectivity reduction rate of formaldehyde and crotonaldehyde exceeds 30%), while tar, nicotine, water and Carbon monoxide and other adsorption properties are basically not reflected; on the other hand, the tobacco material supplements an appropriate amount of tobacco flavor, so that the sensory quality of the cigarette is basically balanced. In addition, the preparation method of the composite material and the filter tip of the present invention is simple, low in cost, and satisfies industrial production.

将25g膨胀石墨均匀的分散于水中，然后慢慢往其中加入70g烟末颗粒(粒径大小20～60目)，超声分散1小时后，加入5g瓜儿胶，超声分散30分钟，过滤，将颗粒物在120℃下干燥24小时得相应的滤嘴添加剂。Disperse 25g of expanded graphite evenly in water, then slowly add 70g of smoke powder particles (particle size 20-60 mesh) to it, after ultrasonic dispersion for 1 hour, add 5g of guar gum, ultrasonically disperse for 30 minutes, filter, and The particles were dried at 120°C for 24 hours to obtain the corresponding filter additives.
实施例5Example 5
将实施例1～4中制备的滤嘴添加剂添加至卷烟滤嘴中，每支滤嘴中的添加剂的施加量为50mg，同时以未添加滤嘴添加剂的卷烟滤嘴作为空白对照。将卷烟平衡后，测试卷烟的常规烟气成分和主流烟气中醛类物质的含量，检测结果如表1和表2所示。The filter additives prepared in Examples 1-4 were added to cigarette filters, and the amount of the additives in each filter was 50 mg, and the cigarette filters without filter additives were used as a blank control. After the cigarettes were balanced, the conventional smoke components and the content of aldehydes in the mainstream smoke were tested. The test results are shown in Table 1 and Table 2.
