Influence and analysis of compound formula and prevulcanization time on the properties of natural rubber latex film
By L9(34)orthogonal test,the paper selected the sulphur,silica,zinc carbonate and accelerator PX to natural rubber latex formula design.The vulcanization characteristics and mechanical properties of the natural latex film were tested by pre-vulcanization test.The results showed that with the prolongation of pre-curing time,the t90 decreased,and the mechanical properties increased.The t90 between different formulations showed a positive correlation,and the tensile strength between different formulations also showed a positive correlation.Using the index membership weighted scoring method,the main order of influence on the mechanical properties of the film was sulfur,silica,zinc carbonate and accelerator PX.And under the optimal formula,the comprehensive estimated value was 1.093.The further verification test showed that the optimal formulation of the compound had application value,and it would provide the basis for the high performance of natural latex film.
