Abstract
The influence of polysulfide and carboxylated butadiene rubbers on the mechanical characteristics of epoxy-rubber adhesives is studied. The optimal concentration of rubbers is determined and the technology of compounding carboxylated rubbers and an epoxy oligomer is described. The character of changes in stress-strain characteristics for bulk specimens and films prepared on the basis of modified and unmodified epoxy oligomers is determined. The procedure for measurement of the wear resistance index is discussed and the advantages of carboxylated rubbers compared to Thiokol are demonstrated. The properties of a new cold-setting epoxy-rubber adhesive with an improved shelf life and good stress-strain and dielectric characteristics are presented.
