| Abstract: | In this paper,the epoxy construction adhesive was toughed by the butyronitrile liquid rubber-40.The influence of the fraction of the butyronitrile rubber-40 in epoxy construction adhesive,the reaction temperature and time of the first ingredient on the shearing strength of cured epoxy resin system were investigated.The result showed that the optimal ratio resin to rubber was 10∶1 and the shearing strength could reach 22.4 MPa after cured 24 h at room temperature,and the mechanical property of adhesive was excellent. |
