PARTICLE SIZE CONTROLLABLE CATIONIC WATERBORNE POLYURETHANE SIZING AGENTS BASED ON SELF-ASSEMBLED AND SELF-EMULSIFIED TECHNOLOGY
A light blue transparent cationic waterborne polyurethane emulsion was prepared by self-assembled and selfemulsified technology.By changing the ratio of hydrophobic and hydrophilic raw materials,the particle size of the waterborne polyurethane emulsion could be controlled as a film former in sizing agents used in the production of carbon fiber,glass fiber and basalt fiber.The polyurethane emulsion was analyzed by Fourier transform infrared analysis,thermogravimetric analysis,particle size analysis and centrifugal stability analysis.Cationic waterborne polyurethane emulsion with a small particle size have good emulsion stability and superior film forming properties prevented it from migrating with water when continuous sized fiber tow is drying.The fibers sized with cationic waterborne polyurethane enhance fibers heat resistance,dustproof performance,filament tensile strength,wetting and interfacial adhesion with resin matrix as well as suppressing the occurrence of monofilament fracturing and wool yarn,etc.
