Butyl rubber has excellent air tightness and is an ideal raw material for the production of rubber inner tubes. Butyl rubber can be used alone in the production of butyl innertubes, or it can be used in combination with other types of rubber to prepare rubber innertubes with better overall performance and longer service life. In actual production, butyl rubber can be combined with chlorobutyl rubber, butyl reclaimed rubber, EPDM rubber, neoprene rubber and other products to produce inner tubes. The editor will share a few formulas with you today.
1. Pure butyl rubber production inner tube formula
100 parts of butyl rubber, 5 parts of zinc oxide, 1.2 parts of stearic acid, 1 part of antioxidant A, 25 parts of carbon black N330, 25 parts of carbon black N774, 20 parts of engine oil, 0.55 parts of accelerator M, 0.5 parts of accelerator ZDC , 1 part of accelerator TMTD, 1.75 parts of sulfur; total: 181 parts.
2. Butyl rubber and chlorinated butyl rubber are used together to produce inner tube formula
50 parts of butyl rubber, 50 parts of chlorinated butyl rubber, 5 parts of zinc oxide, 1.2 parts of stearic acid, 10 parts of carbon black N550, 55 parts of carbon black N774, 28 parts of paraffin oil, 2 parts of accelerator DM, accelerator TMTD 0.3 parts, sulfur 0.5 parts; total: 202 parts.
3. Butyl rubber and butyl reclaimed rubber are used together to produce inner tube formula
90 parts of butyl rubber, 20 parts of butyl reclaimed rubber, 5 parts of zinc oxide, 1.2 parts of stearic acid, 45 parts of carbon black N550, 20 parts of carbon black N660, 17 parts of paraffin oil, 0.55 parts of accelerator DM, and TMTD 1 part, 1.25 parts of sulfur; Total: 201 parts.
4. Butyl rubber and EPDM rubber are used together to produce inner tube formula
85 parts of butyl rubber, 15 parts of EPDM rubber, 5 parts of zinc oxide, 1.2 parts of stearic acid, 25 parts of carbon black N550, 40 parts of carbon black N774, 22 parts of paraffin oil, 0.6 parts of accelerator DM, accelerator 1.6 parts of TMTD, 1.6 parts of sulfur, total: 197 parts.
5. Butyl rubber and neoprene are used together to produce inner tube formula
95 parts of butyl rubber, 5 parts of chloroprene rubber, 5 parts of zinc oxide, 30 parts of carbon black N330, 30 parts of mixed gas carbon black, 5 parts of petroleum jelly, 10 parts of phenolic resin, 2 parts of stannous chloride; total: 182 parts .
In actual production, the combined use of butyl rubber and chlorinated butyl rubber can further increase the vulcanization speed and improve the overall performance of the vulcanized rubber; the combined use of butyl reclaimed rubber can effectively reduce the cost and production energy consumption of the butyl inner tube raw material 2YLYY118. EPDM rubber can be added in the production of butyl rubber inner tubes to improve the rubber processing technology and adhesion while alleviating the problem of aging and softening and stickiness of butyl inner tubes and prolonging the service life. Butyl rubber can also be used with a small amount of chloroprene rubber to improve the aging resistance of butyl inner tubes.
