Hydrogenation Modification of C5 petroleum resin: Hydrogenation mainly have three methods: slurry, fixed bed, spray tower. The production method comprises the following steps: dissolving petroleum resin in a solvent such as cyclohexane or mineral oil, adding nickel or aluminum catalyst supported on alumina or diatomaceous earth, and conducting hydrogenation reaction under the condition of raising temperature, hydrogenation reaction product of reaction product and the hydrogenated modified petroleum resin is obtained after distillation. Maleic anhydride modification of petroleum resin: A silane-modified C5 petroleum resin is blended with a thermoplastic elastomer to provide a hot-melt adhesive composition for road marking lacquers with excellent properties. The hot melt adhesive composition can be used in road marking paint to improve the adhesion of glass beads to the road surface, to enhance its strength, to extend the use of time. |
