Title:

DIAMINO-S-TRIAZINE COMPOUND HAVING CARBAMOYL GROUP AND METHOD FOR CURING EPOXY RESIN WITH THE COMPOUND

Document Type and Number:

Japanese Patent JPH0710850

Kind Code:

A

Abstract:

PURPOSE: To obtain a new diamino-s-triazine compound having a carbamoyl group in the molecule and useful as a curing agent and a curing accelerator for epoxy resins.

CONSTITUTION: A compound of formula I (R1 is CH2CH2, 1,3-phenylene, 1,4- phenylene; R2, R3 are H together, or one of the R2, R3 the other is methyl), e.g. 2-aminoethyl-carbamoyl-ethylene-(4',6'-diamino-1',3',5'-s-triazine)-(2'). This compound is obtained by thermally refluxing 1 mole of a diamino-s-triazine compound of formula II and 3-10 moles of a 1,2-diamine compound of formula III in the presence of monomeric sulfur and subsequently boiling the obtained compound of formula IV in water. A one pack epoxy resin composition using the compound as a curing agent is excellent in storage stability at room temperature, and the employment of the compound as a curing agent or a curing accelerator for epoxy resins gives a cured product little in curing contraction and having excellent toughness.
