titleOfInvention | A kind of super-barrier thermoplastic polyurethane elastomer and preparation method thereof |
abstract | The invention relates to a super-barrier thermoplastic polyurethane elastomer and a preparation method thereof. The super-barrier thermoplastic polyurethane elastomer comprises a thermoplastic polyurethane elastomer and modified nano-silica, and the modified nano-silica is a surface Nano-silica modified with active agent and/or silane coupling agent. The invention creatively adds nano-silica as an additive into the thermoplastic polyurethane elastomer, so that the barrier property is significantly improved on the basis of ensuring excellent mechanical properties. Among them, the surfactant can be adsorbed on the surface of the silica, and the coating can form a space barrier layer, so that the particles are not easily agglomerated, and the particle size of the nano-silica can be controlled, thereby better maintaining the mechanical properties and high barrier properties of the polyurethane; The silane coupling agent can make the hydrophilic nano-silica become lipophilic, make it better dispersed in the polyurethane material, and then better maintain the mechanical properties and high barrier properties of the polyurethane. |
