摘要
通过设计正交试验,讨论了复配阻燃剂的种类、复配阻燃剂的质量浓度、阻燃剂pH值、反应温度、反应时间和层状双羟基金属氧化物(LDHs)的质量浓度对120 g·m-2阻燃纸阻燃效果的影响。研究结果表明,当三聚氰胺(MA)的质量浓度为10 g/L、阻燃剂pH值为7.0、反应温度为50℃、反应时间为15 min、LDHs的质量浓度为30 g/L时,所制备的阻燃纸的氧指数(LOI)为31%,已经达到难燃级;与空白样原纸LOI的18%相比,阻燃纸的阻燃效果提高了72%。
Through orthogonal experiment design,the flame retardant effects of the following elements on flame retardant paper were discussed including the compound flame retardants＇ type,mass concentration and pH value,reaction temperature,reaction time and mass concentration of LDHs.The research results showed that under the condition of the mass concentration of melamine（MA） being 10g/L,pH value 7.0,reaction temperature 50℃,reaction time 15 min,and the mass concentration of LDHs 30 g/L,the oxygen index（LOI） of flame retardant paper was 31%.The flame retardant effect has been increased by 72% as compared with the blank sample base paper with LOI of 18%.
