往玻璃窗上贴一张薄膜，能让老旧房屋在保障采光的同时冬暖夏凉？ 这可不是普通的薄膜，其特殊之处在于添加了一种导热系数低、防火效果好的新型绿色建材——气 凝胶，从而显著降低空调或暖气的能耗。 春节前夕，位于河北省唐山市曹妃甸区南堡经济开发区的中国铁建气凝胶中试生产基地传来喜讯 ——气凝胶材料稳定量产能力突破110吨。在渤海湾畔的中试生产基地里，科技日报记者见到了技术团 队历经5年研发的气凝胶稀金隔热薄膜产品。 这款薄膜产品摸起来如同塑料，泛着微微的淡蓝色，可任意折叠卷曲。它的厚度仅50微米，约为单 张A4纸厚度的一半。 "这张薄膜看着普通轻薄，内里可大有乾坤。"气凝胶材料技术负责人、中国铁建绿色低碳产业技术 研究院绿色建材所所长王栋解释，薄膜由多种复杂结构组合而成，气凝胶浆料就均匀附着在关键功能 层，因此薄膜具有了高隔热、防紫外、高透光的特点。 走进气凝胶中试生产基地车间，反应釜如钢铁巨人般林立眼前，管廊纵横连接，反射着金属光泽。 王栋团队在这里经常试验至凌晨2点。 在气凝胶制备车间里，研究人员王会新指着近3人高的水解缩聚釜回忆了一段往事。去年3月，气凝 胶工艺提升进入关键阶段。一次试验中，他和同伴操作机器引入反 ...

Core Viewpoint - The article highlights the critical safety concerns associated with lithium-ion batteries, particularly the risk of thermal runaway, and emphasizes the new national standard GB 38031-2025, which significantly raises safety requirements for battery packs, creating a billion-dollar market for advanced thermal insulation materials like aerogels [2]. Group 1: Industry Standards and Market Impact - The new national standard requires battery packs to remain non-flammable and non-explosive within 2 hours after a single cell experiences thermal runaway, with all monitoring points maintaining temperatures below 60℃, increasing safety requirements by 24 times [2]. - This regulatory change is expected to lead to a reshuffling in the industry, favoring companies that proactively invest in safety technologies [2]. Group 2: Aerogel as a Solution - Aerogels, known for their ultra-low thermal conductivity of 0.015-0.019 W/(m·K), are identified as the most effective thermal insulation materials currently available, significantly reducing the risk of fire from battery issues [2]. - Companies like BYD are increasingly adopting pre-oxidized fiber aerogel insulation sheets and ceramic aerogel insulation sheets to enhance the safety of electric vehicles [2]. Group 3: Key Players in the Aerogel Market - Zhejiang Yangu Technology Co., Ltd. has invested 800 million yuan in a silica aerogel project, aiming for an annual production capacity of 4 million square meters of aerogel composite materials [3]. - Shenzhen Zhongning Technology Co., Ltd. is recognized as a national-level specialized and innovative enterprise, leading the push for aerogel industrialization in China [6]. - Jiangxi Hongbai New Materials Co., Ltd. has established a production base with an annual capacity of over 10 million pieces of battery insulation pads, reflecting the growing demand in the new energy market [8]. Group 4: Emerging Technologies and Innovations - Companies are developing a range of aerogel products, including flexible aerogel insulation mats and fireproof pads, to meet the increasing demands for safety in high-temperature applications [54]. - The article mentions that the aerogel industry is witnessing significant technological advancements, with companies focusing on creating high-performance aerogel products that can withstand extreme temperatures and provide effective insulation [37][58]. Group 5: Upcoming Events - The 6th Thermal Management Industry Conference and Exposition will take place from December 3-5, 2025, in Shenzhen, focusing on thermal management materials and technologies, including aerogels [86].
