Study on curing reactions of epoxy resin diluted by 1,2-cyclohexanediol diglycidyl ether

In this thesis,the curing reactions between E-44 epoxy resin,the mixture of E-44 epoxy resin and 1,2-cyclohexanediol diglycidyl ether,1,2-cyclohexanediol diglycidyl ether and curing agent DDM were studied by means of differential scanning calorimeter.E-44 epoxy resin was effectively diluted,its apparent activation energy was decreased,its curing reactions activity and reaction rate was increased and the mechanical properties of cured E-44/1,2-cyclohexanediol diglycidyl/DDM system were also increased by adding 1,2-cyclohexanediol diglycidyl to E-44 epoxy system.The values of apparent activation energy were calculated that their were 46.08 kJ/mol,39.50 kJ/mol,35.58 kJ/mol respectively,meanwhile,the values of reaction order were 0.86,0.84,0.83 respectively.
