| titleOfInvention | A kind of preparation method of lignin-based hydrophilic sizing agent and its application in polyolefin composite material |
| abstract | The invention provides a lignin-based hydrophilic sizing agent, a preparation method and its application in polyolefin composite materials. The sizing agent is prepared by the following method: firstly dissolving epoxy resin and ozonated lignin in The organic solvent is heated and stirred to obtain a lignin-based epoxy resin, and then alcoholamine, carboxylic acid and silane coupling agent are added to obtain a lignin-based hydrophilic sizing agent; the carbon fiber is dipped in the sizing agent, dried and placed in a polymer. In the olefin, the carbon fiber reinforced polyolefin composite material is obtained by melt molding. The sizing agent has good interfacial bonding properties, which creates a "bridge effect" between carbon fibers and polyolefins, solves the defects of poor interfacial adhesion between carbon fibers and polyolefins, and improves the mechanical properties of composite materials. The sizing agent prepared by the invention uses water as a medium, avoids the use of organic solvents, has low cost, is environmentally friendly and has good stability. After pretreatment of carbon fiber, the properties of carbon fiber reinforced polyolefin composites are significantly improved. |
