芳纶的生产和应用及专利申请进展

Production and application of aramid fiber and progress in patent applications

介绍了芳纶的生产、应用及专利申请进展。2023年全球对位芳纶生产能力为107.7 kt/a,间位芳纶生产能力为69.0 kt/a,国内对位芳纶生产能力为20.0 kt/a,间位芳纶生产能力为20.9 kt/a,泰和新材集团有限公司是目前国内最大的芳纶生产企业。国际与国内市场芳纶消费结构略有不同,2023年国际市场对位芳纶在安全防护、车用摩擦材料领域消费占比较大,而国内市场对位芳纶的消费领域则主要集中在光学纤维增强和安全防护领域;国际市场间位芳纶在电气绝缘纸、安全防护织物、高温过滤材料领域的消费占比较大,而国内市场间位芳纶主要用在相对低端的高温过滤材料领域;下游高端领域如蜂窝芯材、锂电隔膜等有望成为芳纶新的需求增长点。跨国企业芳纶专利申请量较大,比较注重专利布局和专利保护;芳纶相关专利申请量最多的技术领域涉及生产技术改进、芳纶纸、电池等。指出企业在持续推进芳纶常规应用领域创新的同时,应关注和寻求独特应用领域的技术创新,抢先布局专利,获得更早的专利保护和更大的市场优势。

The progress in the production,application and patent application of aramid fiber was introduced.The global production capacities of p-aramid and m-aramid fibers were 107.7 kt/a and 69 kt/a,respectively,when the production capacities of p-aramid and m-aramid fibers were 20 kt/a and 20.9 kt/a,respectively,in China in 2023.Taihe New Materials Group Co.,Ltd.is currently the largest aramid fiber production enterprise in China.The consumption structure of aramid fiber is slightly different in the international and domestic markets.The proportions of aramid fiber consumption were both great in the fields of safety protection and automotive friction materials in the international market in 2023 while the consumption of aramid fiber was mainly concentrated in the fields of optical fiber reinforcement and safety protection in China market.The consumption proportions of m-aramid fiber were great in the fields of electrical insulation paper,safety protection fabrics and high-temperature filtration materials in the international market,while m-aramid fiber is mainly used in the fields of relatively low-end high-temperature filtration materials field in China market.The downstream high-end fields such as honeycomb core materials and lithium battery separators are expected to become new demand growth points for aramid fiber.Multinational enterprises provide a large patent application volume in China and pay more attention to patent layout and protection.The technology fields corresponding to the highest patent application volume related to aramid fiber involve production technology improvement,aramid paper,batteries,etc.It was pointed out that enterprises should pay attention to the technological innovation in unique application fields in order to proactively make patents layout and obtain earlier patent protection and greater market advantages while continuously promoting innovation in the conventional application field of aramid fiber.
