| Summary, etc | Blends of natural rubber and carboxylated styrene butadiene rubber latex with varying blend ratio were prepared. The blends were vulcanised by different techniques which include sulpur prevulcanisation, and gamma radiation vulcanisation. Morphology of the blends was investigated from scanning electron micrographs. Mechanical properties such as tensile strength, tear strength, elongation at break and modulus were studied with reference to blend ratio and vulcanisation techniques. The crosslink density of the blends and individual components were determined from the swelling and stress-strain measurements. The sulphur prevulcanisation of latices was carried out at 70 degree C for 2 h. The radiation vulcanisation of various systems was carried out using n-butyl acrylate as sensitiser at a dose of 15 kGy/h. The swell ratio of the samples was calculated. The radiation vulcanised systems showed comparable properties as that of sulphur prevulcanised systems. However, the modulus of radiation vulcanised latex films was lower than prevulcanised samples. The gamma radiation vulcanised latices are eco-friendly due to the absence of curing agents. Applicability of various theoretical models were investigated to predict the modulus of the blends. |
