4）By step 3）After prepared mixed sheet parks 6～10h, gasoline is mixed with mixed sheet, mixed sheet is dissolved in gasoline, after dissolving mixed sheet 4～8h, imposing mechanical shearing effect makes rubber cement be uniformly dispersed, that is, described rubber cement is obtained.
4. the preparation method of rubber cement according to claim 3 is it is characterised in that described step 1）Including：
Natural rubber or smoke sheet rubber are put into banbury, it is forced under 0.6～0.8MPa the mixing 1～3 minute that sticks together, then carry and sticking together, put into white carbon black N660, white carbon, zinc oxide, stearic acid, age resistor RE, antioxidant D FG-34 and C5 resin successively, repressurization sticks together mixing 10～12 minutes to 0.6～0.8MPa, add aromatic naphtha when banbury inner chamber temperature reaches 120～140 DEG C, and continue to be forced into 0.6～0.8MPa after clearing up the powder remaining at banbury gap, the dumping when mixer mixing temperature reaches 150～160 DEG C；Then the bottom sheet cooling in mill by sizing material, taps rubber after sizing material bag roller, then the sizing material after rubber tapping is invested in glue pouring roller and instead refines 4～6 back and forth；Fall glue after the completion of, sizing material is thrown in back mill, after bag roller left and right each anti-refine once, bottom sheet, enter interleaving agent tank, cool, upper buttress park, obtain film.
5. the preparation method of rubber cement according to claim 3 is it is characterised in that described step 2）Including：
By step 1）Prepared film puts into banbury, is forced under 0.6～0.8MPa the mixing 5-7 minute that sticks together, the dumping when mixer mixing temperature reaches 120～140 DEG C；Then the bottom sheet cooling in mill by sizing material, taps rubber after sizing material bag roller, then the sizing material after rubber tapping is invested in glue pouring roller and instead refines 4～6 back and forth；Fall glue after the completion of, sizing material is thrown in back mill, after bag roller left and right each anti-refine once, bottom sheet, enter interleaving agent tank, cool, upper buttress park, obtain film.
6. the preparation method of rubber cement according to claim 3 is it is characterised in that described step 3）Including：
By step 2）Prepared film puts into banbury, pressurization, under stick together, knead 1～1.5 minute, dumping before 90～100 DEG C of banbury temperature, the bottom sheet cooling in mill of sizing material after dumping, film temperature is down to when 80～100 DEG C and is added sulfur, Resorcino, rubber adhesive A, reinforcement binding agent SW-RF-1, accelerant CZ, captax, accelerator TT and antiscorching agent PVZ, refine material feeding using mill is counter, the sizing material after the completion of material feeding is tapped rubber after bag roller, then the sizing material after rubber tapping is invested in glue pouring roller；Fall glue after the completion of, by sizing material throws in back mill and instead refine 3～5 back and forth, after bag roller left and right each anti-refine once, bottom sheet, enter interleaving agent tank, cool, upper buttress park, obtain mixed sheet.
