Abstract

The invention provides a kind of super soft epoxy curing agent, which comprises the chemical reaction of combination with four chemicals of diethylenediamine, propylene carbonate, oleic acid, and castor oil. The curing agent is blended into super soft epoxy adhesive with epoxy resin and epoxy diluent. Finally, the super soft epoxy adhesive is used in the application of cloth cover, or widely used in bonding repair, house wall decoration and so on.

Description

Technical field [0001] The invention relates to a super soft epoxy curing agent composition and a preparation method thereof, and belongs to the technical field of curing agents. Background technique [0002] In order to make the thin cloth and epoxy glue adhere firmly, usually another layer of glue is applied to the thin cloth that has been coated with glue. At present, there are existing but single-component adhesives that can achieve the purpose of coating and bonding. But the adhesive needs 250°C to cure. Such curing conditions are too harsh, and now it is necessary to seek a flexible adhesive that can be cured at 80~100°C to achieve the purpose of coating and bonding. [0003] There are mainly the following types of low-temperature curing adhesives in the prior art: [0004] Hydroxy-terminated nitrile rubber modified epoxy adhesive. [0005] Epoxy resin (E-51) 100; [0006] Hydroxyl-terminated liquid nitrile rubber (HTBN) 16; [0007] Diethylenetriamine 10-15; [0008] Dioctyl se...
