The preparation method of the high life solid tyre, which comprises the following steps:
S1, refining glue, to the rubber raw materials point of the rubber raw materials of tread band, the rubber raw materials of fetal rhythm glue-line, base portion glue-line
Refining glue is not carried out on three mixing lines, respectively obtains tread mix, fetal rhythm sizing material, base portion sizing material；
Then S2, cleaning steel ring surface impurity, re-polishing, blasting treatment apply adhesive in steel ring and rubber contact position,
It is dry, for use；
S3, by the base portion sizing material in S1, through open mill heat refining extruded sheet, then steel stand-by in S2 is crimped onto through molding machine
On circle, then fetal rhythm sizing material, tread mix be successively crimped onto the steel ring outer surface that there is glue on surface through open mill, molding machine, obtained
Solid tyre to be vulcanized；
S4, by the solid tyre to be vulcanized in S3, be put into mold, heating vulcanization, 145 DEG C, vulcanize 55~80 minutes,
Obtain high life solid tyre.
In terms of reinforcement system, mainly select white carbon black, by white carbon black reduce sizing material heat on significant effect；Si-69
Can make the reinforcing effect of white carbon black enhances.The addition of aramid fiber can improve the thermal conductivity of carcass to a certain extent.This is
Consider on carcass heating rate direction from reducing, extends the service life of solid tyre.
On the other hand, rare earth anti-aging agent is good to the protection effect of natural rubber, especially on thermo-oxidative ageing.
Compared with prior art, the present invention replaces carbon black by white carbon black, reduces the heat generation rate inside carcass；Aramid fiber is added
Fiber forms quick conductive channel in carcass；Traditional anti-aging agent is replaced with lanthanide rare anti-aging agent；In all directions delay rubber
The process of aging, and then solid tyre stability in use is improved, extend the service life of solid tyre.
