Solving the problem of thermal runaway and explosion in lithium batteries, Yipu New Material's nanoscale hexagonal sheet MC60 has been granted a national invention patent


Battery China learned that recently, the technology of "hexagonal flake cyanuric acid melamine and its preparation method and application" independently developed by Shandong Yipu New Material Co., Ltd. (hereinafter referred to as "Yipu New Material") was granted an invention patent by the China National Intellectual Property Administration. This technological breakthrough not only fills the gap in the global nanoscale hexagonal sheet MCA, but also gives the product a leading position internationally with its unique catalytic reaction pathway and nanoscale particle size control ability, bringing revolutionary solutions to the field of halogen-free flame retardant materials, marking a new level of global competitiveness for Yipu New Materials in green chemistry and advanced materials

01

Exploring new markets: Targeting high-end demand and seizing global market share

It is reported that traditional MCA materials are mainly used in the field of low-end plastic flame retardancy due to their large particle size, poor dispersibility, unstable crystal structure, and low temperature resistance. Shandong Yipu New Materials has developed a breakthrough technology to prepare nanoscale hexagonal sheet cyanuric acid melamine (MC60A), which has a hexagonal sheet crystal structure, an average particle size controlled below 0.3 μ m, uniform morphology, high surface activity, and high temperature resistance. It is particularly suitable for lithium battery separator coatings and can effectively solve the problem of explosion caused by thermal runaway of lithium batteries. This product is widely used in high-end fields with strict requirements for flame retardancy, such as ultra-thin flexible copper-clad laminates (FCCL), FFC insulation films, FFC reinforcement boards, circuit boards, photocatalysts, new energy vehicles, aerospace composite materials, etc.

02

Technological breakthrough: leap from "micrometer level" to "nanometer level"

It is reported that traditional MCA has unstable crystal structure, with an average particle size usually between 2-10 μ m, and is prone to agglomeration, resulting in low flame retardant efficiency and poor processing performance. The research and development team of Yipu New Materials innovatively introduced catalysts in MCA synthesis, achieved precise tuning through a stepwise reaction mechanism, controlled crystal growth along the hexagonal sheet direction, and ultimately obtained narrow particle size distribution (D50<0.3 μ m), nanoscale hexagonal sheet MCA powder. This process breaks through the bottleneck of traditional processes in terms of crystal structure and particle size, and increases flame retardant efficiency by 40%, reaching the international leading level.

Conceptual innovation: paradigm shift from "experience driven" to "molecular design"

The core breakthrough of Shandong Yipu New Materials' invention patent lies in the R&D team's precise analysis of hydrogen bonding mechanisms through quantum chemical simulations, and the first proposal of the "template induced directional growth" theoretical model, which enables active design of product morphology and properties at the molecular scale. This innovative concept breaks the industry's inertia of relying on the "trial and error method" to improve processes, laying a methodological foundation for the development of the next generation of functional high-end MCA.

For Shandong Yipu New Materials, the technology patent authorization has strengthened Yipu New Materials' global discourse power in the field of nanoscale hexagonal sheet cyanuric acid melamine (MCA), directly blocking competitors' imitation path; In addition, by promoting the upgrading of the industrial chain and relying on this technology, the company can extend the development of customized high profit products downstream, enhancing its control over the value chain; At the same time, it promotes the acceleration of enterprise green transformation, zero emissions in the process, and meets the requirements of the EU REACH regulation and the "dual carbon" target.

With this major technological breakthrough, Shandong Yipu New Materials not only achieved a leapfrog improvement in the performance of downstream halogen-free flame retardant materials, but also explored an efficient path of "basic research technology development industrial transformation". This achievement marks that Chinese enterprises have shifted from "following" to "leading" in the field of high-end flame retardant materials, contributing Chinese solutions to the upgrading of the global halogen-free flame retardant new material industry.

Standing at the forefront of new technologies in the world, Yipu New Materials is writing the rise story of China's new materials industry with the posture of an "innovator". In the future, Shandong Yipu New Materials will continue to deepen its green manufacturing technology in the field of halogen-free flame retardants, and stride towards the goal of becoming a "global leader in high-end materials".
