A method for joining waterproof vulcanized synthetic rubber sheets wherein a cold-vulcanizable adhesive tape having a Mooney viscosity (ML1+5 (100°C.)) of from 5 to 25 and an autoadhesion property, and which is prepared from a blend of (1) 100 parts by weight of a rubbery polymer, (2) from 1 to 2 pa

A method for joining waterproof vulcanized synthetic rubber sheets wherein a cold-vulcanizable adhesive tape having a Mooney viscosity (ML1+5 (100°C.)) of from 5 to 25 and an autoadhesion property, and which is prepared from a blend of (1) 100 parts by weight of a rubbery polymer, (2) from 1 to 2 parts by weight of an oxime vulcanizing agent or from 1 to 3 parts by weight of sulfur or a sulfur-containing vulcanizing agent, (3) from 3 to 4 parts by weight of a PbO2 vulcanization accelerator in the case of using an oxime vulcanizing agent or from 2 to 6 parts by weight of a thiazole, thiuram, or dithiocarbamate vulcanization accelerator in the case of using a sulfur or sulfur-containing vulcanizing agent, (4) from 30 to 100 parts by weight of an adhesive agent, and (5) from 30 to 150 parts by weight of a softening agent, is placed between overlapped areas of waterproof vulcanized synthetic rubber sheets and pressed to provide an initial adhesive strength of from 0.5 to 3 kg/25 mm, and the adhesive tape is cold-vulcanized to join the sheets.
