| titleOfInvention | Emulsion type sizing agent for carbon fiber as well as preparation method and application of emulsion type sizing agent |
| abstract | The invention discloses an emulsion type sizing agent for a carbon fiber as well as a preparation method and application of the emulsion type sizing agent. The sizing agent contains 2-40 percent of epoxy resin, 0-97 percent of water, 0.5-14 percent of surfactant, 0.3-12.5 percent of cardanol, 0.1-1.5 percent of formaldehyde and 0.1-2.0 percent of inorganic ammonium salts. The emulsion type sizing agent contains the cardanol and the formaldehyde as toughening and modifying agents, so that when the carbon fiber sized by using the emulsion type sizing agent for the carbon fiber is compounded with an epoxide resin matrix taking polyamine as a curing agent to form a composite material, the interlaminar shear strength is improved by over 30 percent and the carbon fiber composite material is enabled to have higher integral performance. The emulsion type sizing agent contains the inorganic ammonium salts, so that the storage stability of the sizing agent is greatly improved and the phenomena of demixing and non-uniformity of concentration are avoided. According to the emulsion type sizing agent disclosed by the invention, the phenomena of demixing and emulsion breaking in the use process of the sizing agent are avoided. After the carbon fiber sized by the sizing agent disclosed by the invention is stored at normal temperature for five years, the mass percentage of the sizing agent on the surface of the carbon fiber is unchanged. |
