Sepiolite,also known as"refractory clay",has good properties such as thermal insulation,high temperature resistance and thermal stability.The experiment uses sepiolite as the core substrate,C18-chlorinated alkanes as the organic component,and magnesium chloride as the inorganic component.A new type of sepiolite flame retardant is prepared by hydrothermal precipitation method and applied in textiles and paper products for flame retardancy.The results showed that the cotton fabric treated with flame retardant had an average flaming time of 1.27 s,an average afterglow time of 4.86 s,and an average damaged length of 47.20 mm;the kraft paper treated with flame retardant has an average flaming time of 0.94 s,an average glowing time of 4.30 s,and an average char length of 42.80 mm,all of which meet the Chinese national standards for flame-retardant fabrics and flame retardant paper,proving that this new flame retardant has good flame-retardant properties.
