Description

可生物降解的香烟过滤嘴棒及香烟 Biodegradable cigarette filter stick and cigarette

技术领域 Technical field

本发明涉及一种香烟过滤嘴棒及设置有过滤嘴的香烟，所述香烟过滤嘴棒是采用聚丁二酸丁二醇酯（PBS)聚合物为基材树脂加工而成，具有优良的生物降解性。背景技术 The present invention relates to a cigarette filter rod and a cigarette provided with a filter. The cigarette filter rod is processed by using a polybutylene succinate (PBS) polymer as a base resin, and has excellent biodegradability. Background technique

香烟过滤嘴具有过滤、阻挡和吸附烟气中烟碱、焦油等有害成分的作用，好的过滤嘴材料除具有上述作用外，还应该能改善烟气的口感，减少烟气对口腔的剌激及对人体健康的伤害。作为一个比较成熟的技术，目前用于制造香烟过滤嘴的材料一般是以醋酸纤维素纤维和聚丙烯纤维为原料，从加工性能和最终生产过滤嘴的综合使用性能考虑，以醋酸纤维素纤维为首选，在中高档卷烟中多使用醋酸纤维素纤维滤嘴。 The cigarette filter has the function of filtering, blocking and adsorbing harmful components such as nicotine and tar in the flue gas. In addition to the above functions, the good filter material should also improve the taste of the flue gas and reduce the stimulation of the flue gas to the oral cavity. Human health damage. As a relatively mature technology, the materials currently used in the manufacture of cigarette filters are generally made of cellulose acetate fibers and polypropylene fibers. From the viewpoint of processing properties and the comprehensive performance of the final production filter, cellulose acetate fibers are preferred. More cellulose acetate fiber filters are used in medium and high-grade cigarettes.

香烟吸完后剩下的过滤嘴部分是要丢弃的，而醋酸纤维素纤维和聚丙烯纤维在自然环境中很难被生物降解，香烟在背负有害人体健康的罪名的基础上，同时还造成了对环境的污染。人类不能完全离开香烟，除了减少香烟本身对人体的危害以外，解决滤嘴丢弃带来的环境污染问题就成为香烟行业必须面对的课题。 The remaining part of the filter after the cigarette is sucked is discarded, and the cellulose acetate fiber and the polypropylene fiber are difficult to be biodegraded in the natural environment. The cigarette is on the basis of the crime of harmful human health, and it also causes Environmental pollution. Human beings cannot completely leave cigarettes. In addition to reducing the harm of cigarettes themselves to the human body, solving the environmental pollution problem caused by filter disposal has become a problem that the cigarette industry must face.

另一方面，醋酸纤维素纤维是以优质木材为原料得到的化工产品，从木材到纤维素再到酯化的醋酸纤维素需要消耗大量的木材原料，而生产环节中也伴随着很多污染问题。 On the other hand, cellulose acetate fiber is a chemical product obtained from high-quality wood. From cellulose to cellulose to esterified cellulose acetate, a large amount of wood raw material is consumed, and many pollution problems are accompanied by production.

所以，无论是从木材资源匮乏，还是从改善环境污染角度出发，寻找替代现有的醋酸纤维素和聚丙烯纤维原料的可生物降解材料，制造出可降解的香烟过滤嘴棒，至少在环境保护方面降低香烟生产所带来的危害，是香烟生产行业急需解决的问题。香烟过滤嘴棒的生产工艺主要包括对原料实施熔融纺丝制成烟用丝束，以及增塑定型制棒最终加工成过滤嘴棒的工艺过程，原料的可纺性能，即，是否容易纺成适合烟用的细旦纤维，以及纤维丝束的牵伸性能和粘合效果，最终都将影响滤棒和滤嘴的综合性能，包括滤过性能，以及外观、硬度和空阻等机械性能。醋酸纤维素纤维就是由于这些性质的优异，才被选择成为香烟过滤嘴的主要加工原料。在寻找其替代材料时，既具有生物降解性，还必须满足过滤嘴棒加工要求，是缺一不可的二个条件。 Therefore, whether it is from the lack of wood resources or from the perspective of improving environmental pollution, look for biodegradable materials that replace existing cellulose acetate and polypropylene fiber materials to produce degradable cigarette filter rods, at least in terms of environmental protection. Reducing the harm caused by cigarette production is an urgent problem to be solved in the cigarette production industry. The production process of the cigarette filter rod mainly includes the process of melt-spinning the raw material into a tobacco tow, and the process of plasticizing the shaped rod to be finally processed into a filter rod, and the spinnability of the raw material, that is, whether it is easy to be spun into a suitable smoke. The fine fibers used, as well as the drawability and adhesion of the fiber tow, will ultimately affect the overall performance of the filter rod and filter, including filtration performance, as well as mechanical properties such as appearance, hardness and air resistance. Cellulose acetate fiber is selected as the main processing material for cigarette filters due to its excellent properties. When looking for alternative materials, it is biodegradable and must meet the requirements of filter rod processing. It is the indispensable condition.

聚丁二酸丁二醇酯（PBS)是一种可生物降解的聚合物，它可以在细菌或酶的作用下最终降解为二氧化碳和水等物质，所以目前开始在塑料领域使用，以缓解传统塑料对环境造成的污染。根据目前的研究和报道， PBS 塑料可制备膜类包装材料，例如可降解塑料袋、一次性餐具的片材原料等； PBS塑料还可以在农用地膜方面以及一些日用杂品方面应用。 Polybutylene succinate (PBS) is a biodegradable polymer that can be degraded into carbon dioxide and water under the action of bacteria or enzymes. Therefore, it is currently used in the plastics field to alleviate the tradition. The pollution caused by plastics to the environment. According to current research and reports, PBS plastics can be used to prepare film packaging materials, such as degradable plastic bags, sheet materials for disposable tableware, etc. PBS plastics can also be used in agricultural film and some daily sundries.

由于香烟过滤嘴的特殊要求，有关利用 PBS作为基材树脂制备的香烟过滤嘴棒还没有记载。发明内容 Due to the special requirements of cigarette filters, cigarette filter rods prepared using PBS as a base resin have not been described. Summary of the invention

本发明主要解决的技术问题在于提供一种可生物降解的香烟过滤嘴棒，采用可生物降解的聚丁二酸丁二醇酯高分子聚合物作为基材树脂，所提供的香烟过滤嘴棒具有与目前通用的香烟过滤嘴棒性能相当，而丢弃的过滤嘴可被环境中微生物分解，利于对环境的保护。 The technical problem mainly solved by the present invention is to provide a biodegradable cigarette filter rod, which uses a biodegradable polybutylene succinate polymer as a base resin, and provides a cigarette filter rod with current The universal cigarette filter rod has the same performance, and the discarded filter can be decomposed by microorganisms in the environment, which is beneficial to the environment.

Polymer materials are currently being used more for degradable plastics. The applicants have found that PBS can be used as a basic material to adjust and change the processing technology to produce cigarette filter rods and filters. At the same time that the comprehensive performance reaches the level of the cellulose acetate filter, the filter can be degraded as soon as it is discarded, and it is applied in the cigarette industry, which will have more significant social benefits for protecting the environment.

所以，本发明首先提供了一种可生物降解的香烟过滤嘴棒，该香烟过滤嘴棒是利用原料组成包括 90-100^%的聚丁二酸丁二醇酯聚合物和 0-10wt%的稳定剂的可生物降解的烟用纤维（丝束）加工而成。 Therefore, the present invention firstly provides a biodegradable cigarette filter rod which utilizes a raw material composition comprising 90-100% of polybutylene succinate polymer and 0-10% by weight of a stabilizer.
