Abstract:

In order to improving flame retardant,smoke suppressant and anti droplet properties of polyvinyl chloride (PVC) textile strucure materials, inorganic flame retardant  zinc(2ZnO ?3B2O3 ?3.5H2O) and aluminum hydroxide were synergisticto prepare flame retardant polyvinyl chloride textile structure materials. The influence of 2ZnO ?3B2O3 ?3.5H2O/Al(OH)3 on the properties of polyvinyl chloride textile structure materials were analyzed by limiting oxygen index instrument, smoke density instrument TG and SEM. The results showed that 2ZnOB ?3B2O3 ?3.5H2O/Al(OH)3 is effective in flame retardancy, smoke suppression and anti-droplet properties of polyvinyl chloride chloride textile structure material. The higher the contents of 2ZnO ?3B2O3 ?3.5H2O are, the better smoke suppressant properties of polyvinyl chloride textile structure materials. The aging treatment also influences the stability of PVC, and its limiting oxygen index value is first increased and then decreased with the thermal oxidative treatment time increasing. The limiting oxygen index value increased with the increase of photo-oxidative treatment time.
