Abstract

An application of a carbonaceous heat source material in a heating type tobacco product. The carbonaceous heat source material comprises a carrier of an activated carbon fiber and a carbon heat source at least attached to the carrier in a wet blending manner. The porous structure of the activated carbon fiber ensures that the carbon heat source is basically in an attached state during a whole burning process, so that the falling of burning ashes is also reduced; moreover, the flexible function of the activated carbon fiber serves as a mechanical support framework of the whole material, so that the integrity of the overall structure of the ashes is ensured, and thus the falling of the burning ashes is reduced. By means of the thermal conductivity of the activated carbon fiber and a promotion effect of the activated carbon fiber on the dispersion of the carbon heat source, burning is effectively prompted, such that a burning effect is not damaged and the falling of the burning ashes is effectively reduced.

Description

一种碳质热源材料在加热型烟草制品上的应用Application of a carbonaceous heat source material in heated tobacco products 技术领域technical field
本申请涉及烟草制品的技术领域，尤其涉及一种碳质热源材料在加热型烟草制品上的应用。The present application relates to the technical field of tobacco products, in particular to the application of a carbonaceous heat source material in heated tobacco products.
背景技术Background technique
由于传统卷烟产品在吸食过程中释放出较多的颗粒物、焦油及多种挥发性有机物，对吸食者造成潜在的健康危害，随着技术创新的不断发展，新型烟草制品逐渐被消费者接受。新型烟草制品大概可以分四个大类：第一类是电子烟、第二类是加热型烟草制品、第三类是***烟、第四类是其他一些制品。所有这些制品都有三个共同特征：第一个是不要需燃烧，第二个是提供尼古丁能在一定程度上满足消费者的生理需要，第三个是基本无焦油。因此，新型烟草制品在满足消费者生理需求的同时，大大降低了消费者的健康风险。Because traditional cigarette products release more particulate matter, tar and various volatile organic compounds during smoking, causing potential health hazards to smokers, with the continuous development of technological innovation, new tobacco products are gradually accepted by consumers. New tobacco products can be roughly divided into four categories: the first category is electronic cigarettes, the second category is heated tobacco products, the third category is snus, and the fourth category is other products. All of these products have three common features: the first is that they do not need to be burned, the second is that the provision of nicotine can satisfy the physiological needs of consumers to a certain extent, and the third is that they are basically tar-free. Therefore, while meeting the physiological needs of consumers, new tobacco products greatly reduce the health risks of consumers.
加热型烟草制品与传统的卷烟最本质的区别是利用外部热源加热烟草而不是点燃烟草，以“加热型”为思路设计的“低温卷烟”，能使烟叶刚好加热到足以散发出味道的程度，而不会点燃烟叶。目前市场在售或在研的加热型烟草制品可以分为如下几类：电加热型（如电阻加热、电磁感应加热、红外加热等）、燃料加热型（如气态、液态、固态燃料等）、理化反应加热型（如物理结晶、化学反应等）。目前电加热型卷烟专利主要采用电阻、电磁感应、红外、激光和微波加热等多种方式，其中电阻加热是当前的技术主流。The most essential difference between heated tobacco products and traditional cigarettes is that they use an external heat source to heat the tobacco instead of igniting it. The "low-temperature cigarette" designed with the idea of "heating type" can heat the tobacco leaves just enough to give off flavor. without igniting the tobacco leaves. Heated tobacco products currently on sale or under development in the market can be divided into the following categories: electric heating type (such as resistance heating, electromagnetic induction heating, infrared heating, etc.), fuel heating type (such as gaseous, liquid, solid fuel, etc.), Physical and chemical reaction heating type (such as physical crystallization, chemical reaction, etc.). At present, electric heating cigarette patents mainly use resistance, electromagnetic induction, infrared, laser and microwave heating and other methods, among which resistance heating is the current mainstream technology.
与电加热相比，燃料加热型卷烟从形态和使用方式上更接近传统的卷烟，主要包括加热段和烟草段，利用燃料燃烧作为热源对烟草进行加热，使烟草材料在加热状态下干馏，满足消费者的抽吸需求。从理论上讲，任何可燃烧的固体、液体和气体物质如碳粉、乙醇、丁烷、天然气、氢气等都可以作为燃料为加热不燃烧烟支提供热源，但是从安全、携带方便、使用简单的角度来看，以固体含碳材料为热源存在突出优势。Compared with electric heating, fuel-heated cigarettes are closer to traditional cigarettes in terms of shape and use, mainly including a heating section and a tobacco section, using fuel combustion as a heat source to heat the tobacco, so that the tobacco material is dry-distilled in a heated state to meet Consumer demand for suction. Theoretically speaking, any combustible solid, liquid and gaseous substances such as carbon powder, ethanol, butane, natural gas, hydrogen, etc. can be used as fuel to provide heat sources for heating non-burning cigarettes. From the point of view, there are outstanding advantages of using solid carbonaceous materials as heat sources.
已知技术中出现了较多披露碳质热源材料的报道。如中国发明专利CN 101420876 A公开了一种非燃烧型吸烟物品用碳质热源组成物，其为将已知的任何碳、0.5～5％多元醇、5～15％粘结剂和30～55％碳酸钙混合挤压而成，使用藻酸盐( 例如铵盐、钠盐)、羧甲基纤维素或其盐( 例如钠盐)、果胶、角叉菜胶或其盐( 例如钠盐) 和愈创树胶等作为粘结剂，所使用的碳(粒子)来源(原料) 没有特别限制。There are many reports disclosing carbonaceous heat source materials in the known technologies. For example, Chinese invention patent CN 101420876 A discloses a carbonaceous heat source composition for non-combustible smoking articles, which is any known carbon, 0.5-5% polyol, 5-15% binder and 30-55% % Calcium carbonate mixed and extruded, using alginate (such as ammonium salt, sodium salt), carboxymethyl cellulose or its salt (such as sodium salt), pectin, carrageenan or its salt (such as sodium salt ) and guaiac gum etc. as the binder, the source (raw material) of carbon (particles) used is not particularly limited.
技术问题technical problem
然而，以上述为典型代表的碳质热源难以兼顾燃烧效果和灰烬不脱落效果。However, it is difficult for the above-mentioned carbonaceous heat sources to take into account both the combustion effect and the ash non-shedding effect.
技术解决方案technical solution
有鉴于此，本申请提供碳质热源的负载材料及其应用，能够在不损害燃烧效果的同时有效降低燃烧灰烬脱落。In view of this, the present application provides a carbonaceous heat source loading material and its application, which can effectively reduce the falling off of combustion ash without compromising the combustion effect.
已为普遍意识到的是，提高燃烧效果的手段通常聚焦于提高碳粉的含量或添加助燃的改机助剂或者类似手段。降低灰烬脱落的手段通常聚焦于增加粘接剂含量或者类似手段。这意味着燃烧效果的提升通常会带来灰烬脱落的加剧，降低燃烧灰烬脱落的手段实施的同时通常会损害燃烧效果，例如燃烧不充分等，即燃烧效果的提升与降低燃烧灰烬脱落二者矛盾体的统一性似乎难于找寻，这一直困扰着技术人员。It is generally recognized that the means to improve the combustion effect usually focus on increasing the content of carbon powder or adding combustion-supporting engine modification aids or similar means. Approaches to reducing ash shedding typically focus on increasing the binder content or similar. This means that the improvement of combustion effect will usually lead to the intensification of ash shedding, and the implementation of measures to reduce the ash shedding of combustion will usually damage the combustion effect, such as insufficient combustion, that is, there is a contradiction between the improvement of combustion effect and the reduction of ash shedding The unity of the body seems to be difficult to find, which has been perplexing technicians.
一种被广泛使用的应对燃烧效果的提升与降低燃烧灰烬脱落的不统一性的方法是，采用在碳质热源成型体的外表面施加诸如玻璃纤维等其他隔热材料以进行束缚，例如CN109793264A所涉及一种隔热毡、其制备方法及用于炭加热不燃烧卷烟的用途。然而，该方法仅仅只能被动地去阻挡灰烬向外部外露，并不能着力于碳质材料本身的改进，即本质上无法减轻燃烧灰烬脱落的问题。更重要的是，这些隔热材料在碳质热源燃烧过程中会释放对人体有害的物质和潜在的健康风险。A widely used method for improving the combustion effect and reducing the non-uniformity of burning ash falling off is to apply other heat insulating materials such as glass fiber on the outer surface of the carbonaceous heat source molding for restraint, such as CN109793264A The invention relates to a thermal insulation blanket, a preparation method thereof and an application for heating non-burning cigarettes with charcoal. However, this method can only passively block the ash from being exposed to the outside, and cannot focus on the improvement of the carbonaceous material itself, that is, it cannot alleviate the problem of burning ash falling off in essence. More importantly, these insulation materials will release harmful substances and potential health risks during the combustion of carbonaceous heat sources.
本申请人意外地发现，活性炭纤维具有“多孔状纤维”属性和“炭”属性，“多孔状纤维”属性一方面能够将发挥燃烧功能的炭热源利用其多孔的物理性吸附起到较好的附着作用，从而维持炭热源燃烧形成的灰烬维持原始团聚状态，二方面能够利用自身的柔性作为整个体系的力学骨架，足以支撑炭热源燃烧后灰烬团聚状态的不被外力破坏松散，这从根本上实现了燃烧灰烬的不松散；三方面， “多孔状纤维”的多孔状使得炭热源在其上的附着是高分散性的，避免了炭热源的聚集体的尺寸过大，确保了炭热源必要的燃烧充分性；四方面，能够利用碳纤维良好导热性，确保了炭热源被引燃时的热量所需要，从而促进燃烧效率。此四个方面，实现了在不损害燃烧效果的同时有效降低燃烧灰烬脱落。The applicant unexpectedly found that activated carbon fibers have the attributes of "porous fiber" and "charcoal". Adhesion, so as to maintain the original agglomeration state of the ash formed by the combustion of the charcoal heat source. On the other hand, it can use its own flexibility as the mechanical framework of the whole system, which is enough to support the ash reunion state after the charcoal heat source is burned. The burning ash is not loose; three aspects, the porous shape of the "porous fiber" makes the attachment of the charcoal heat source on it highly dispersed, avoiding the excessive size of the aggregate of the charcoal heat source, and ensuring that the charcoal heat source is necessary. In four aspects, the good thermal conductivity of carbon fiber can be used to ensure the heat required by the charcoal heat source when it is ignited, thereby promoting combustion efficiency. These four aspects can effectively reduce the falling off of combustion ash while not impairing the combustion effect.
应当注意的是，由于活性炭纤维本质是碳纤维，其固有燃点较高，在炭热源的燃烧过程中显然是不容易被点燃的，这为活性炭纤维发挥上述力学支撑骨架功能铸牢基础。 It should be noted that since the activated carbon fiber is carbon fiber in nature, its intrinsic ignition point is high, and it is obviously not easy to be ignited during the combustion process of the charcoal heat source, which lays a solid foundation for the activated carbon fiber to play the above-mentioned mechanical support skeleton function.
 “炭”属性能够消除了其与炭热源所存在的材料的相容性差异，从而实现与炭热源的较好的相容，最终确保炭热源在其上附着的稳定性和牢固性，进而促使炭热源在体系中的位置稳固的永恒性，活性炭纤维维持炭热源燃烧形成的灰烬维持原始团聚状态铸牢基础。由此，才创立了本发明创造。The "charcoal" attribute can eliminate the compatibility difference between it and the material that exists in the carbon heat source, so as to achieve better compatibility with the carbon heat source, and finally ensure the stability and firmness of the carbon heat source attached to it, thereby promoting The position of the charcoal heat source in the system is stable and eternal, and the activated carbon fiber maintains the ash formed by the combustion of the charcoal heat source to maintain the original agglomeration state and cast a solid foundation. Thus, the present invention is created.
