Research of Epoxy Adhesive Modified by Polyurethane

Full Text(PDF, 186KB)

Author: Tao Yang, Guanghong Fan, Mingwei Ren

Abstract: This paper studied the experimental synthesis of polyurethane modified epoxy resin cured at room temperature. Through infrared spectrum detection means, it could accurately grasp the degree of reaction; and it could make the use of universal testing machine to test the mechanical properties of adhesives. The tensile shear strength of the adhesive system was improved by adding nano filler. The results show that when the curing agent content is 50 phr, the curing time is 60 mins at room temperature and the tensile shear strength can reach 10.31 MPa. When 1% nano filler silica is added, the tensile shear strength reaches 14.10 MPa. Its toughness is better than the toughness of epoxy resin.

Keywords: Isocyanate, toughening, epoxy resin, nano fille,
