- Ammonia and HTT were compounded and tested as a novel preservative system for concentrated natural rubber latex (CNRL) to replace traditional preservatives. The preservation effects and the viscosity of prevulcanized CNRL were measured. After preservation treatment, the drying characteristics, the mechanical properties and IR of vulcanized natural rubber latex films were evaluated. It was found that 0.4% w/w ammonia and 0.1% w/w HTT allowed the preservation of CNRL for more than 180 days. The volatile fatty acid number (VFA NO.) and mechanical stability test (MST) of the preserved materials met the ISO 2004:2010(E) standard. In addition, the viscosity of prevulcanized CNRL exhibited little change. The drying time of vulcanized NRL film was relatively short which indicated that the drying efficiency of products were higher. The tensile strength and tear strength reached 34.81 MPa and 46.43 kN/m respectively, higher than that achieved using the traditional method of preservation. Additionally, the results of IR showed that ammonia/HTT compound preservative did not change the constitution of vulcanized NRL film.
