Through constantly research and experiment, the connection between theory and practice, technical scheme of the present invention has been broken through following technological difficulties:
1. in raw material, confirmed the zinc oxide of reasonable proportion.Zinc oxide can effectively improve the thermal oxidation resistance function of butyl rubber.Capsular use temperature can be near 200 °, and good thermotolerance helps to prolong capsular work-ing life.The content of zinc oxide is low excessively, and DeGrain then for improving having little significance of capsule die, and after the addition of oxidisability is excessive, can have a negative impact again, mainly is to reduce sizing material to return original shape and elongation.Tyre capsule is in the working conditions of upholding repeatedly, need possess good elongation.Therefore, need be through experiment and summary repeatedly, could a final reasonable proportion confirming zinc oxide, between the thermotolerance of capsule die and elongation, average out.
2. the Viscotrol C molecular weight is lower, and viscosity is less, can improve the flowing property of sizing material, but compares and paraffin, can reduce the intensity of sizing material.In raw material, added paraffin and can improve the influence of tenderizer for rubber strength.Because paraffin and butyl rubber have good consistency, can reduce the plasticity-of Mooney viscosity, raising sizing material.Therefore, paraffin and Viscotrol C replenish each other, and Viscotrol C is main, and paraffin is auxilliary, common tenderizer as butyl rubber.As preferably, said paraffin is Microcrystalline Wax.Microcrystalline Wax also contains many belt length side chains and cyclic saturability hydrocarbon polymer except normal paraffin and isoparaffin are formed, fusing point is high, and plasticity-is good, can improve the colloidal flowing property better.
3. confirmed suitable curing temperature.Curing temperature is an important parameter in the sulfidation, and curing temperature is high, and vulcanization reaction is fast, and production efficiency is just high; Curing temperature is low, and vulcanization reaction is slow, and production efficiency is just low.So actual production is under the prerequisite that guarantees vulcanized quality, improve curing temperature as far as possible, thereby faster production is enhanced productivity.Yet too high temperature can cause the cracking of sizing material molecular chain, even the reversion phenomenon takes place, and causes the decline of mechanical property.According to experimental data, the curing temperature of butyl rubber should not be higher than 170 °, and the optimum curing temperature of neoprene latex is 145 °.Therefore, suitable temperature is most important for equilibrium cure speed and vulcanized quality.
4. in the one-step melting method, rational step and parameter have been set.Mixing method of two steps is with respect to the one-step melting method, and mixing time is longer, and efficient is lower.And the shortcoming that adopts the one-step melting method is that mixing time is short, and composition disperses inhomogeneous.Therefore, need to confirm rational mixing order, mixing time and a melting temperature.
Compare with traditional tyre capsule and preparation method thereof, the beneficial effect that radial tyre capsule of the present invention and preparation method thereof is obtained is embodied in the following aspects:
1. under the constant basically situation of tyre capsule elongation, improve the colloidal resistance toheat, prolonged the work-ing life of tyre capsule.
