Modification research of epoxy resin with aminopolysiloxane

Epoxy resin was modified with aminopolysiloxane.In the case of the preparation of epoxy resin /aminopolysiloxane adhesive,the influence of all the variables on the mechanic performance was researched,such as the modification time,the modification temperature,the mass ratio of epoxy resin to aminopolysiloxane,the amino number and inherent viscosity of the aminopolysiloxane.In the result,the toughness of epoxy resin was improved greatly.
