| Abstract | Natural rubber (NR) latex was vulcanised by exposing it to ultraviolet (UV) irradiation for 1.5 hours in the presence of 1,6 hexanediol diacrylate (HDDA), n-Butyl acrylate (n-BA), and trimethylolpropane trimethacrylate (TMPTMA). 2-hydroxy-2-methyl-1-phenylpropanoid was used as a photoinitiator. The effect of HDDA, n-BA, and TMPTMA on the physical, and thermal properties of ultraviolet irradiation vulcanisation natural rubber latex (UVNRL) was investigated. The wetting and absorption of acrylate monomer into NR film were determined by using contact angles, and absorption tests. Tensile strength, modulus, and crosslink density were investigated to study the physical properties. The Fourier Transform Infrared spectroscopy (FTIR) was used to determine the chemical interaction between acrylate monomer, and NR. The thermal properties of UVNRL samples were determined using a thermogravimetric analyser (TGA), and a differential scanning calorimetry (DSC). It was found that NR latex formulated with HDDA had the highest tensile value and stable thermal degradation. The carbonyl group attached in UVNRL is shown in the FTIR spectrum. The diffusion of acrylate monomer into NR latex particles and the number of functional groups in acrylate monomer influenced the properties of UVNRL. |
