| Abstract: |
| The application of environment-friendly new ammonia-free preservative in the preparation
of ammonia-free latex was investigated. The results showed that new environment-friendly ammonia-free
preservative was soluble in water，was not volatile，and had no odor or irritating smell. The fresh latex did not
deteriorate within 48 h by using new ammonia-free preservative with addition level of 0. 02 mass fraction of
fresh latex. The ammonia-free preservative/accelerator TMTD/zinc oxide had good preservation effect in
the concentrated latex. The use of new ammonia-free preservative could reduce environmental pollution and
improve working conditions. |
