And electrical insulating property, had a wide range of applications in fields such as chemical industry, electrical equipment, building, aviations.Traditional epoxy resin is all solvent
Property, substantial amounts of VOC pollutions environment is caused, meanwhile, the volatilization of solvent and inflammability make epoxy resin in construction, transport, storage side
There is larger potential safety hazard in face, detrimental effect is also resulted in health, and a large amount of use of solvent can also make application
Cost improves, therefore replaces the aqueous epoxy resins of solvent to turn into recent years new development trend with water, as a kind of environment-friendly
Type product, more and more extensive concern is obtained.
Epoxy resin must arrange in pairs or groups with curing agent to be had significant practical applications using just tool, and the species of curing agent is varied,
Increasing research concentrates on epoxy hardener field, with reference to the trend of water-borne modification of epoxy resin, assigns curing agent emulsification work(
The study hotspot of aqueous epoxy resin systems can be turned into, make curing agent in addition to being acted on crosslinking curing, while play emulsification
The effect of epoxy resin.Traditional aqueous epoxy curing agent is mostly the modifier of aliphatic polyamine, and epoxy resin is carried out with polyamines
Reaction solidification.During the course of the reaction, to ensure dispersiveness of the curing agent in water, commonly use organic acid and neutralize into salt, to keep breast
Liquid is stable.And organic acid can cause film performance to decline, easily got rusty with metal.Therefore, non-ion aqueous epoxy is developed
Curing agent is with a wide range of applications.
