Nano Zinc Borate

The nano zinc borate, whose manufacturer is Taixing, has improved the flame retardancy, smoke suppression, and catalytic efficiency of zinc borate by an order of magnitude through its huge specific surface area and quantum confinement effect. At the same time, it completely solves the century old problem of "compatibility but non fusion" between traditional fillers and polymer matrices, significantly improving the mechanical properties and thermal stability of products, and providing new support for the design of next-generation ultra-high performance, high transparency, ultra-thin wall, and intrinsic flame retardant composite materials.

Core strengths

1. Quantum confinement effect catalyzed low-temperature and high-efficiency flame retardant pathway

The chemical reaction of traditional micrometer level zinc borate relies on bulk thermal conduction, while the nanocrystals of Taixing's nano zinc borate have extremely high surface atomic ratios and unique electronic states.

·Reaction activity leap: The surface activity energy is significantly reduced, enabling key flame retardant reactions such as catalytic polymer carbonization and quenching of free radicals to be initiated at a faster rate at lower temperatures.

·Disappearance of diffusion path: Nanoparticles are uniformly dispersed between polymer chains, with almost zero contact distance with flammable molecules and decomposition products, achieving zero distance extinguishing and reducing flame retardant response time by more than 70%.

2. A three-dimensional continuous enhanced interface constructed with a super large specific surface area

The huge interface provided by nanoparticles is not passively present, but through our patented interface design, it forms strong physical adsorption and chemical interactions with polymer molecular chains.

·Intrinsic toughening mechanism: Nanoparticles, as movable physical cross-linking points, can effectively induce silver lines and shear bands, absorb impact energy, and achieve "toughening while enhancing", overturning the traditional understanding that fillers damage mechanical properties.

·Gas barrier network: Uniformly dispersed nanoparticles form a tortuous maze like barrier in the material, greatly delaying the diffusion rate of flammable volatiles and oxygen, and suppressing combustion from the propagation path.

3. The optical transparency and rheological advantages conferred by nanoscale

·The application of Rayleigh scattering theory: When the particle size is much smaller than the visible light wavelength (<1/10, i.e.<40nm), the scattering of light can be neglected. This makes it possible to prepare highly transparent and flame-retardant PC, PMMA, and epoxy resins with reasonable addition amounts, opening up the high-end optical device market.

·Zero shear thinning behavior: Nanoparticles have a much smaller effect on the viscosity of polymer melts than micron fillers, and can even act as lubricants in some systems, resulting in excellent processing flowability at ultra-high filling levels, making them suitable for precision injection molding and ultra-thin extrusion.

Application scenarios

1. Consumer Electronics and Optical Devices

·Challenge: Smartphone backplate, smartwatch cover, AR/VR lens require high transparency, high gloss, scratch resistance, and meet UL94 V-0 or higher flame retardant standards.

2. Miniaturization and high-density electronic packaging

·Challenge: Chip packaging adhesive (EMC) and underfill require ultra-high purity, extremely low ion content, excellent thermal insulation, and flame retardancy under ultra-thin layer thickness.

3. High performance fiber composite materials

·Challenge: Carbon fiber/glass fiber reinforced epoxy or polyimide composite materials need to meet aerospace flame retardant standards (such as FAR 25.853) while reducing weight and maintaining extremely high mechanical properties.

4. Special films and coatings

·Challenge: Prepare flame retardant, high barrier, and flexible special films for insulation of new energy battery packs and flexible circuit substrates.

Frequently Asked Questions

Q: How to ensure that nanoparticles do not agglomerate during the processing? This is the biggest challenge in the application of nanotechnology.

A: We solve the problem through a dual strategy of "in-situ polymerization dispersion" and "precise control of surface energy". Firstly, the product has already formed a stable slurry in its exclusive dispersion medium when it leaves the factory, which can be directly used for solution mixing or in-situ polymerization. For melt processing, our patented surface treatment technology enables the surface energy to perfectly match the surface energy of the target polymer melt, and can spontaneously disperse under shear force. We can even provide 'masterbatch pre dispersion' to ensure that users can achieve nano dispersion effects with the simplest process.

Q: What are the advantages of nano zinc borate compared to emerging nano flame retardants such as carbon nanotubes and graphene?

A: The core advantage lies in "multifunctionality, easy decentralization, and controllable cost". Carbon nanotubes and graphene mainly provide gas-phase barrier and conductivity, but they are difficult to disperse, have dark colors, are extremely expensive, and have complex effects on mechanical properties. Nano zinc borate combines gas-phase flame retardancy, condensed phase carbonization catalysis, smoke suppression, and enhancement, presenting a white color and facilitating large-scale production. It achieves the best balance between comprehensive performance, processability, and cost, making it a more practical nano flame retardant solution with engineering value.
