EPOXY RESIN COMPOSITION WITH RAPID CURING AND LOW LINEAR SHRINKAGE

WIPO Patent Application WO/2018/036506

A1

An epoxy resin composition with rapid curing and low linear shrinkage, composed of an epoxy resin, an amine curing agent, and an additive. The ratio of the epoxy equivalent of the epoxy resin to the active hydrogen equivalent of the amine curing agent is 1.0/0.8 to 1.0/1.2. The epoxy resin comprises an aromatic epoxy resin constituting 85-100% of the total weight of the epoxy resin and an aliphatic epoxy resin and/or an alicyclic epoxy resin constituting 0-15% of the total weight of the epoxy resin. An aliphatic amine curing agent and/or an alicyclic amine curing agent in the amine curing agent constitute/constitutes 60-100% of the total weight of the amine curing agent. The added amount of the additive is 0-50% of the total weight of the epoxy resin and the amine curing agent. The epoxy resin composition has a gelation time less than 170 seconds at 120°C and a linear shrinkage percentage of 1.0% or less after curing, achieving the effect of rapid curing and low linear shrinkage. The epoxy resin composition is applicable to parts and components of a new energy vehicle, rail transit, and aerospace vehicle, and can improve productivity and product yield, achieving the effects of energy saving, reducing carbon emission, and environmental protection.
