Description

一种抗菌吸臭艾草鞋垫及其制备方法和应用An antibacterial and odor-absorbing mugwort insole and its preparation method and application 技术领域Technical field
本申请属于鞋垫技术领域，例如一种抗菌吸臭艾草鞋垫及其制备方法和应用。The present application belongs to the technical field of insoles, such as an antibacterial and odor-absorbing mugwort insole and its preparation method and application.
背景技术Background technique
鞋垫是鞋子的重要组成部分，由于鞋垫在使用时会直接与人体接触，所以说鞋垫的重要性会直接影响鞋子的舒适度；同时随着人们生活水平的不断提升，对于鞋垫已经不仅仅是舒适度的要求，还要求鞋垫具有其他功能，例如透气、吸汗、防臭、防霉或按摩等功能。Insoles are an important part of shoes. Since insoles will be in direct contact with the human body during use, the importance of insoles will directly affect the comfort of shoes. At the same time, with the continuous improvement of people's living standards, insoles are no longer just comfortable. In addition, insoles are also required to have other functions, such as breathability, sweat absorption, anti-odor, anti-mildew or massage functions.
目前，相关技术中提供的鞋垫大多是由棉或者高分子材料制成。其中，棉质鞋垫仍是目前最常用的鞋垫种类，棉质鞋垫的其主要优势在于吸汗性能优异，且亲肤柔软；但是众所周知，棉的吸水性强，但是抑菌性并不强，耐磨性也较差。高分子材料中聚氨酯发泡材料是目前常用的鞋垫材料，聚氨酯发泡鞋垫具备高回弹性和耐穿性的优点，且具备良好的穿着体验，是高端鞋垫的常用选材。此外聚氨酯发泡鞋垫的制备工艺相对成熟、生产效率较高。因此，聚氨酯发泡鞋垫的产品配方和生产工艺的革新均受到广泛关注。Currently, most of the insoles provided in related technologies are made of cotton or polymer materials. Among them, cotton insoles are still the most commonly used type of insoles. The main advantages of cotton insoles are excellent sweat absorption and softness against the skin. However, as we all know, cotton has strong water absorption, but is not very antibacterial and wear-resistant. Sex is also poor. Among polymer materials, polyurethane foam is currently a commonly used insole material. Polyurethane foam insoles have the advantages of high resilience and durability, and have a good wearing experience. They are a commonly used material for high-end insoles. In addition, the preparation process of polyurethane foam insoles is relatively mature and the production efficiency is high. Therefore, innovations in the product formula and production process of polyurethane foam insoles have received widespread attention.
但是，聚氨酯发泡材料本身不具备吸汗除臭和抑菌的功能，所以目前常用下述手段来提升聚氨酯发泡鞋垫的抑菌、吸臭除汗性能。一是在聚氨酯发泡鞋垫上设置面层材料，在面层添加具有抑菌性能的粉末或者面层选用具有抑菌性能的织物。CN109924605A公开了一种防治足癣的中草药鞋垫，所述鞋垫包括表层、中间填充层和橡胶底层；所述中间填充层填充中草药粉末；所述中草药粉末是由中药组合物制成的；所述中药组合物包括如下重量份的组分：金樱根 18～23份、党参17～24份、当归20～25份、穿心莲12～16份、单面针17～25份、功劳木16～27份、鸡血藤15～20份、千斤拔12～17份；该鞋垫中使用的中草药组合物是根据中药配伍理论，针对足癣的治疗需要，充分发挥中药相生相克、相辅相成的作用，复配而成，疗效显著，制备简单，所述鞋垫对足癣的预防治疗效果显著，无毒副作用，对多种足部真菌具有显著的抑菌活性，可标本兼治，不易复发，使用方便安全舒适，应用前景好。CN112806667A公开了一种汉麻中草药足护按摩养生抑菌鞋垫及其制备方法，鞋垫本体包括聚氨酯层，聚氨酯层耐磨性高、质量轻，聚氨酯层的上表面压制有上麻布层，聚氨酯层的下表面压制有下麻布层，麻布的制作工艺使其透气性增强、抑菌性增强、吸水性增强，聚氨酯层的空腔内放置有以下原料：薰衣草1～3g、迷迭香2～3g、薄荷1～3g；艾草3～4g；桉树叶1～2g；珍珠粉1～2g；黄柏3～4g；苦参3～4g；土荆皮3～4g；罗勒2～3g；柠檬草2～3g，上述中药具有健脾、安神、清热解毒、温经通络、行气活血，解毒消肿的功效，因此使用中药后的鞋垫对人体起到养生保健的作用。但是上述方法存在抑菌效果一般、多次穿着后抑菌性能快速下降的问题。However, polyurethane foam material itself does not have the functions of absorbing sweat, deodorizing and antibacterial, so the following methods are currently commonly used to improve the antibacterial, odor absorbing and desweating properties of polyurethane foam insoles. One is to set a surface layer material on the polyurethane foam insole, add powder with antibacterial properties to the surface layer, or use a fabric with antibacterial properties for the surface layer. CN109924605A discloses a Chinese herbal medicine insole for preventing and treating tinea pedis.
