Abstract:

In order to benefit at natural rubber for research ,development and utilization, benefit at rubber products material, comply with the strategy of sustainable development route, improve natural rubber products economic benefits, performance of fresh nature rubber latex, properties of raw rubber, vulcanization characteristics of compounded rubber and the properties of physical and mechanical vulcanized rubber about Reyan RRIM600, Reyan 7-20-59, Reyan 88-13, Reyan 7-33-97, PR107 and Reyan 8-79 strains of 6 kinds of rubber tree were studied. The results showed that chemical ingredient of natural rubber latex, properties of raw rubber different of strain were diversity; dry rubber content and impurity content of Reyan 8-79 were highest; ashes content and acetone solute of Reyan 7-20-59 were highest; vulcanized rubber of Reyan 8-79 and Reyan 7-33-97 had a longest vulcanizing time, while Reyan 88-13 was shortest; physical and mechanical vulcanized rubber of Reyan RRIM600 were best.
