| titleOfInvention | Hyperbranched polyester grafted carbon nanotube flexibilizer and preparation method thereof |
| abstract | The invention provides a hyperbranched polyester grafted carbon nanotube flexibilizer, which is prepared by taking 2, 2-dimethylolpropionic acid and 1,1, 1-trimethylolpropane as raw materials, adding a catalyst p-toluenesulfonic acid for reaction to obtain hyperbranched polyester, and adding an active end group modifier, a surface-activated carbon nanotube and a dimethylformamide solvent for composite modification; wherein the molar ratio of the 2, 2-dimethylolpropionic acid to the 1,1, 1-trimethylolpropane is 1: and 6, the surface-activated carbon nano tube is 0.5g, and the molar ratio of the active end group modifier to the hyperbranched polyester is 1: 1. The hyperbranched polyester grafted carbon nanotube flexibilizer can enhance the flexibility, strength and durability of epoxy asphalt, has good crystallization resistance, and can be used for toughening epoxy asphalt and epoxy resin. The preparation method of the toughening agent has the advantages of simple process, easy operation, low cost, reaction temperature of 60-170 ℃, normal reaction pressure, lower requirement on reaction conditions, safety and reliability. |
