Refining, then puts into mould inhibitor, and banburying is carried out in closed plastics processing mill, and mixing temperature is controlled in 130-170 DEG C of dumping, and the time is
15-20 minutes；After parking, elastomeric compound and crosslinking agent are put into closed plastics processing mill and carry out banburying, temperature control during banburying
At 60-120 DEG C, the time is 2-5 minutes；
Cd, the compound after banburying is put into two-roll mill, the roller temperature of two-roll mill is controlled in 40-80 DEG C, roller
Away from formation piece glue when being arranged on 5-10mm, and send out film；
De, shaping are rubber fastening band finished product.
9. a kind of mildewproof rubber waterstop preparation technology according to claim 7 or 8, it is characterised in that also wrapped in dispensing
Fire retardant is included, fire retardant is put into together with mould inhibitor.
10. the preparation technology of the mildewproof rubber waterstop according to claim 7 or 8, it is characterised in that：Described step e
During shaping, mould proof waterstop finished product is molded into by vulcanizer, the upper and lower plates temperature control of vulcanizer is at 150-170 DEG C；Or
It is molded by extrusion die, mould proof waterstop finished product is shaped into through microwave vulcanization.
