Elastomer material, composite damping base plate thereof and preparation method of base plate

The invention relates to the technical field of vibration reduction, in particular to an elastomer material, a composite vibration reduction base plate of the elastomer material and a preparation method of the base plate. The elastomer material comprises two materials, an active agent hydroxyl-terminated polybutadiene is added into a damping rubber component, and double bonds of the active agent hydroxyl-terminated polybutadiene can participate in vulcanization reaction of rubber; the terminal hydroxyl group can participate in the cross-linking reaction of the polyurethane elastomer, so that chemical interface bonding is formed between the two elastomers, and the use stability of the prepared periodic composite base plate is kept; according to the preparation scheme of the composite vibration reduction base plate, the inelastic layer and the elastomer are compounded through a secondary rotary mold vulcanization process, and the prepared composite vibration reduction base plate is stable in structure and good
