Since it is necessary to invest in the waste tire thermal cracking project, it is first necessary to understand the consumable material composition of the tire manufacturing to know the real result of thermal cracking of the waste tire. In order to solve the infeasibility of the waste tire thermal cracking project from the source, I have provided some information on the materials needed for the tire manufacturing, with the help of many experts in the tire industry, which is not suitable for the thermal cracking project. Provided evidence. Through analysis and exchange, I hope to help entrepreneurs who want to invest in waste tire thermal cracking projects.

The main materials for manufacturing tires basically require natural rubber, butadiene rubber, styrene butadiene rubber, chlorinated rubber, carbon black, zinc oxide, stearic acid, insoluble sulfur, environmentally friendly oil, resin, cobalt salt, protective agent, steel wire, fiber. Wait.

It contains natural rubber: SMR10, SMR20; synthetic rubber: butadiene rubber BR900, low-cis Li-BR, styrene-butadiene rubber SBR1500; carbon black: N115, N375, N330, N326, N660 and white carbon black; chemical additives: even Joint TESPT (50%), stearic acid, zinc oxide, DTPD (3100), anti-6PPD (4020), anti-TMQ, B-type microcrystalline wax, plasticizer A, KORESIN resin, t-butyl phenolic viscosity Resin, octyl phenolic tackifying resin, C5 resin, hydrocarbon resin mixture 40MFS, solid reinforcing phenolic resin, cobalt neodecanoate, resorcinol formaldehyde resin, high styrene S6H, aromatic oil, RA-65, ordinary sulfur , insoluble sulfur IS7020, HD0T20, accelerator CZ, accelerator NS, accelerator DZ, accelerator HNT, anti-coke agent CTP, steel wire: steel wire, carcass wire 3+9+15×0.22+0.15NT, belt Layer steel wire 3+9+15×0.22+0.15NT, belt steel wire 3×4×0.22HE, sub-coated steel wire 3×0.24/9×0.225+0.15CCHT and textile cord, etc., due to tire use and specifications Different, the proportion of materials varies.
At present, the material consumption and rubber formula of the production tires are not standardized, but the materials consumed are basically the same. For example, the list of tire consumption materials of truck 1200R20 specification shows that natural rubber is 38.9%, synthetic rubber is 4.32%; steel wire is 25.29%; textile 0 %; 9.46% of additives such as antioxidants, antiozonants, and vulcanization systems; and 22% of fillers (carbon black).

Some manufacturers of car / light truck tire manufacturing materials are natural rubber 20%; synthetic rubber 28%; filler (carbon black) 26%; antioxidants, anti-ozonant, vulcanization system and other additives 10%; steel cord 7% ; bead wire 4%; textile cord 5%. Three kinds of specifications are natural rubber; 11 kinds of synthetic rubber; 7 kinds of carbon black; 14 kinds of chemicals and steel cord, bead wire, textile cord and so on.

The consumption of materials from tire manufacturing shows that the natural rubber consumption of truck tires is higher than that of car/light truck tires; the consumption of synthetic rubber for car/light truck tires is higher than that of truck tires; the consumption of steel for truck tires is higher than that for cars/light truck tires; the use of textile fabrics for car/light truck tires Truck tires do not use textile cords; other auxiliaries such as antioxidants, antiozonants, vulcanization systems, and fillers (carbon black) consume substantially the same material.
