一种阻燃抑烟热塑性聚氨酯复合材料及其制备方法与应用
By introducing specific types of flame retardants and smoke-suppressing synergistic components into TPU materials, a thermoplastic polyurethane composite material with flame retardancy, smoke suppression, and mechanical properties was prepared. This solved the problems of TPU materials being flammable, prone to melting and dripping, and releasing smoke, achieving highly efficient flame retardancy and low smoke effects while maintaining the material's flexibility and processing performance.

AI Technical Summary
Existing TPU materials are flammable, have a high heat release rate during combustion, and are accompanied by melting and dripping, producing a large amount of smoke and harmful gases, resulting in a high fire hazard. Furthermore, the combination of traditional flame retardants and smoke suppressants may lead to material embrittlement and a decrease in mechanical properties, making it difficult to meet the requirements of high flexibility applications such as cable sheaths.
A thermoplastic polyurethane composite material was prepared by melt blending a combination of phosphorus-containing/phosphorus-nitrogen flame retardants such as piperazine pyrophosphate (PAPP), aluminum diethylphosphite (ADP), ammonium polyphosphate (APP), and 10-(2,5-dihydroxyphenyl)-10H-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO-HQ) with smoke-suppressing synergistic components such as layered bimetallic hydroxide (LDH), magnesium hydroxide (MH), molybdenum trioxide (MoO3), ammonium octamolate (AM), and zinc borate (ZB). The addition amounts of flame retardant components and smoke-suppressing synergistic components were controlled to achieve a synergistic improvement in flame retardancy, smoke suppression, and mechanical properties.
It significantly reduces peak heat release rate and smoke release, improves fire growth rate, maintains material flexibility and processing performance, meets the high flexibility and high reliability service requirements of wire and cable sheaths, and achieves simultaneous improvement in flame retardancy, smoke suppression and mechanical properties.
