| Overview | resorcinol diglycidyl ether (RDGE), A resorcinol epoxy resin. Epoxy resin containing resorcinol group. The biggest characteristic is high reactivity, viscosity drop is obvious, fast curing, high cross-linking density, than with other diluents have better hardness, heat resistance, electrical insulation and chemical resistance. Mainly used as epoxy resin reactive diluent, can improve the heat resistance, the reference dosage in 5%-20%. It can also be used as a matrix epoxy resin. High reactivity, high cross-linking density, cured heat resistance, electrical insulation and chemical stability, can be used for high heat resistance cast plastics, fiber composites, adhesives and coatings, electrical potting materials and reactive diluents. It can be used as a viscosity modifier of phenolic resin. |
| preparation method | synthesis method: weigh resorcinol and ECH according to the ratio, add them to three-necked flask in sequence, and then add the catalyst triphenylphosphorus, the temperature was controlled at 90 to 100 ° C. While stirring at elevated temperature. After completion of the etherification, when the material was cooled to 30 ° C., a small amount of anhydrous alcohol was added thereto, and powdered sodium hydroxide was further added four times in an amount of 2.4 times the mass of the Resorcinol. Control the temperature at 28~32 ℃, heat preservation after adding 4~6h, vacuum fractionated materials, washed with anhydrous ethanol, the water formed in the material and the unreacted ECH were removed by distillation under reduced pressure so that the temperature of the material did not exceed 120 °c. The material was fractionated under reduced pressure again, and a pure RDGE resin was prepared after removing impurities.|
| Application | is mainly used as reactive diluent of epoxy resin, which can improve heat resistance, and the reference dosage is 5%-20%. It can also be used as a matrix epoxy resin. High reactivity, high cross-linking density, cured heat resistance, electrical insulation and chemical stability, can be used for high heat resistance cast plastics, fiber composites, adhesives and coatings, electrical potting materials and reactive diluents. It can be used as a viscosity modifier of phenolic resin. |
