Performance and Application of Brominated Ethylene Oxide Ester Resin

In the epoxy ethane ester resin series, brominated epoxy ethane ester resin has flame retardancy, expanding the application range of epoxy ethane ester resin. Brominated epoxy resin skeleton has no ester groups and has good hydrolysis stability to water and alkali; The secondary hydroxyl groups on the epoxy skeleton improve the wettability with glass fibers; The resin curing only occurs at both ends of the molecule, which means that the entire length of the molecular chain can be extended under stress, so that the absorption force or Thermal shock shows high elongation at break and impact toughness in macro performance; The epoxy skeleton contains bromine elements, and its flame retardancy is inherent rather than achieved through additives. Therefore, while ensuring flame retardancy requirements, its mechanical properties, corrosion resistance, and construction process performance are not reduced, which is very valuable.
The domestic development and application of vinyl bromide ester resin varieties have some shortcomings in mechanical properties, corrosion resistance, flame retardancy, and construction technology, such as good flame retardancy, but the mechanical properties of the resin exhibit brittleness; Good mechanical performance, but poor corrosion resistance, especially poor alkali resistance.
Based on the fundamental principle that the macroscopic properties of the resin reflect its microstructure, a brominated epoxy resin with good comprehensive properties was synthesized and characterized.
Brominated epoxy resin is a flame retardant resin with excellent comprehensive performance. It expands the application field of Vinyl ester resin resin, and provides a new variety of excellent corrosion resistant and flame retardant FRP that is the same as the imported flame retardant Vinyl ester resin resin.
