浅析聚氨酯泡沫塑料的燃烧毒性

Analysis on the combustion toxicity of polyurethane foam

聚氨酯泡沫塑料在燃烧时产生的毒性问题是严重的环境隐患。传统阻燃剂虽然提高了材料的抗燃性,但在燃烧过程中仍会释放有毒气体和烟雾,对环境和人体健康构成威胁。本研究开发了一种新型无卤环保阻燃剂YKGB-100,旨在不改变聚氨酯泡沫的原有发泡工艺的条件下,提升其阻燃性能,同时显著减少燃烧时产生的有害烟雾和气体。通过使用YKGB-100处理聚氨酯泡沫,并进行系列标准化测试,研究证实了其在提高材料阻燃性能的同时,能有效减少有害烟雾和气体的释放。此外,对小鼠的行为和体重变化观察表明了YKGB-100在减少燃烧毒性方面的潜在生物学优势。因此,YKGB-100提供了一种有效减少聚氨酯泡沫燃烧毒性的新方案,对环境保护和健康安全具有重要意义。

The toxicity of polyurethane foam during combustion is a serious environmental hazard.Although traditional flame retardants improve the flame resistance of materials,they still release toxic gases and smoke during combustion,posing a threat to the environment and human health.This research developed a new halogen-free environmental flame retardant YKGB-10,which aims to improve the flame retardancy of polyurethane foam without changing the original foaming process,and significantly reduce harmful smoke and gas generated during combustion.YKGB-100 was used to treat polyurethane foam,and a series of standardized tests were carried out.The study confirmed that it can effectively reduce the release of harmful smoke and gas while improving the flame retardancy of the material.In addition,observations of behavior and weight changes in mice indicate the potential biological advantages of YKGB-100 in reducing combustion toxicity.Therefore,YKGB-100 provides a new scheme to effectively reduce the combustion toxicity of polyurethane foam,which is of great significance to environmental protection and health and safety.
