METHOD OF PREPARING MOTHER MIXTURE FOR OZONE-RESISTANT BUTADIENE- NITRILE-BASED RUBBER |
| 摘要 |
FIELD: rubber industry. SUBSTANCE: butadiene- nitrile rubber is mixed with suspension-polymerization polyvinylchloride at 70:30 ratio in presence of stabilizer epoxy resin in amount 1-3 weight parts per 100 weight parts of polymer component mixture. Mixing is performed in rubber mixer at 170 <EMI ID=0.368 HE=3 WI=3 TI=CHI> 3 C for 7-9 min or at 160 <EMI ID=0.369 HE=3 WI=3 TI=CHI> 3 C for 14-16 min, rotation speed being 60 rpm. Use of high-toxicity heat stabilizers û heavy metal salts û is eliminated. EFFECT: improved environmental condition. 3 tbl1
