| titleOfInvention | Low-viscosity liquid oxygen compatible epoxy resin system for wet-process fiber winding and preparation method thereof |
| abstract | The invention discloses a low-viscosity liquid oxygen compatible epoxy resin system for wet fiber winding and a preparation method thereof, wherein the method comprises the following steps: (1) modification of matrix resin: uniformly mixing epoxy resin and a phosphorus-containing reactive flame retardant, and reacting under the action of a catalyst to obtain modified phosphorus-containing epoxy resin with the phosphorus content of 1.5-4 wt%; (2) heating the modified phosphorus-containing epoxy resin, then adding the high-temperature-resistant epoxy resin, raising the temperature, and stirring until the resins are uniformly mixed; and then cooling, adding a liquid flame retardant and a diluent, continuing stirring, adding an amine curing agent, and uniformly stirring to obtain the epoxy resin system which is low in viscosity and compatible with liquid oxygen and is used for wet-process fiber winding. The epoxy resin system prepared by the invention can be operated for 2-4 h at 40-60 ℃ and has viscosity lower than 800mPa & s. The mechanical property can reach that the elongation at break is 1.8-2.1 percent and the tensile strength reaches 150-170 MPa. The method is simple and the product has high cost performance. |
