Unformatted text preview: powder (0.0, 0.05, 0.1 and 0.15 % of bitumen weight) were added in optimum bitumen of asphalt concretes, then specific weight and Marshall test were evaluated. These asphalt -rubber mixtures were found to act quite differently from traditional, unmodified asphalt mixture s. However, these results indicate that improved pavement performance can be achieved with asphalt-rubber binder. th 223 23rd-25th June 2010 3rd ICYC 2010 Universiti Sains Malaysia POLY-O11 EFFECT OF PARAMETERS ON DEVELOPMENT OF WATER SOLUBLE POLYURETHANE BINDER 1 N.

Sipaut 1 2 2 School of Chemical Sciences, Universiti Sains Malaysia, 11800 Pulau Pinang, Malaysia School of Engineering and Information Technology, Universiti Malaysia Sabah, Beg Berkunci No. 2073, 88999 Kota Kinabalu, Sabah, Malaysia E-mail: [email protected] 1 Self-polishing copolymer paints (SPC) based on soluble binder have been known for the most successful anti-fouling paint for the prevention of marine biofoulings. In this research, the synthesis and development of water-soluble binder based on polyurethane were studied. Isophorone Diisocyanate -1 (IPDI) and Polyethylene glycol (PEG) with different molecular weight ranging from 1000 to 1500 g mol was used as a based monomer in the formation of polyurethane binder. The ratio between IPDI: PEG, and its concentration as well as the processing parameters such as temperature and time reaction were varied. All samples were characterized using fourier transform infrared spectroscopy (FTIR), thermogravimetry analysis (TGA), gas permeation chromatography (GPC), viscosity, solubility test, drying observation and adhesion test are varied. The solubility test showed the higher molecular weight of PEG and decrease of sample viscosity, the more polyurethane samples soluble in water system. The TGA analysis for the solid polyurethane samples showed small amount of water remained in the samples that cause the formation of some air bubbles during the coating.
