Embodiment 1
[0059] In Embodiment 1, the method for retreading a tire with a precured annular tread includes the following steps:
[0060] Adopt pre-vulcanization process to make continuous annular tread;
[0061] For tires that need to be retreaded, sand the crown of the carcass;
[0062] The back side of the ring tread is polished to the same roughness RMA as the tire crown of the carcass, and the RMA is between 3 and 4;
[0063] Coat the normal temperature vulcanizing agent evenly on the surface of the carcass crown;
[0064] Use a radial expansion device to coaxially wrap the annular tread on the outer circumference of the tire;
[0065] At an ambient temperature of 40±5℃, apply 8-11kg / cm between the annular tread and the carcass. 2 After 45-75 minutes of pressure, the annular tread and the carcass are vulcanized to form an integral structure.
[0066] Such as figure 1 As shown, the method steps of pre-vulcanizing toroidal tread are as follows,
[0067] Rubber mixing process, mixing the raw materia...
