METHOD OF PREPARING EPOXY RUBBER COMPOSITIONS Russian patent published in 1996 - IPC

Abstract RU 2063336 C1

FIELD: rubber industry. SUBSTANCE: epoxy rubber ED-20 is mixed with liquid carboxylate rubber CKH1OKTP in a mechanical mixer. Further mixing of the composition components is carried out under shear deformation conditions until a deformation shear of 5000-9000 is reached. Content of rubber in the composition is 10-50 wt %. Parameters of the epoxy rubber composition with 10 wt % rubber are the following: tensile strength 20.6-22.3 MPa, relative elongation 34.0-34.2%, adhesive strength 19.6-24.0 MPa, mixing time 22.5-24.4 min. EFFECT: new adhesive and sealing compositions obtained. 5 tbl
