Flame-retardant ultraviolet-resistant aramid fiber |
| abstract |
A flame-retardant ultraviolet-resistant aramid fiber, the preparation method therefor comprising the following steps: adding nanoparticles into a hydrogen peroxide solution, performing magnetic stirring for 0.5-1 h, adding a sulfuric acid solution, and further performing magnetic stirring for 0.5 h; performing filtering to obtain a filter cake, and washing the filter cake with water and drying same to obtain modified particles; modifying the modified particles with curcumin and dopamine to obtain organic substance-modified particles; and finally subjecting the organic substance-modified particles to a reaction with a siliconmethoxylated aramid fiber, so as to obtain a surface-modified aramid fiber. The present invention has high ultraviolet absorption and extremely low catalytic activity, avoiding damage to a fiber structure by photocatalysis in a radiation process, and in particular improving flame retardancy of the aramid fiber. |
