Özet

Modified natural rosins were evaluated as binders in the production of thermoplastic road marking paints (TRMPs). Pine rosin (GR), wood rosin (WR), and tall oil rosin (TOR) were used. Fourier transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), matrix -assisted laser desorption/ionization (MALDI-ToF-MS), and gel permeation chromatography -high pressure liquid chromatography (GPC-H PLC) were performed on natural and modified rosins. Acid number (mg KOH/g) ASTM D 465 - 05 and softening point, (degrees C) ASTM E 28 - 99 standard tests were applied to the samples. For the optimum synthesis condition, the pentaerythritol/rosin mol/mol ratio is 1/1, with the levels of Irganox 1425/rosin w/w, 0.5%, and TBM-6/rosin w/w, 1.0%. Gel permeation chromatography -high pressure analysis revealed that the esterification reaction yield was over 90% for each of the three natural rosins. Moreover, chromaticity coordinates (x,y), gloss factor (8), softening point (degrees C), and UVB aging test were applied to TRMPs. Modified natural rosins showed better results in the production of TRMPs. This is an important development and crucial step for sustainable TRMP production.
