For the tyre ring reinforcement glue of above-mentioned aircraft tire bead reinforcement glue-line, its formula is made up of the raw material of following weight parts ratio:
Preferably, the weight proportion of each raw material is:
This tyre ring reinforcement glue, with 1
#smoke sheet rubber is main material, also has cis-1,4-polybutadiene rubber, universal carbon black, silane coupling agent, thermo-stabilizer, anti-recovery agent, zinc oxide to be that main subsidiary material are made by said ratio.This reinforcement glue has Heat stability is good, elasticity is high, heat-dissipating is low performance characteristics, has tensile strength, tensile yield and 300% stress at definite elongation higher, the advantage that after dynamic compression fatigue, tension set is less simultaneously.
The working conditions of large aerospace tire is that load is large, air pressure is low, tyre bead portion stressed large, distortion is large, between the casingply and sidewall rubber on large aerospace tire bead top, set up the tyre ring reinforcement glue-line with snappiness, low-heat-generation, good thermotolerance and good heat conductivility, buffering and endergonic effect can be played.
By formulating of recipe, in formula, use 1
#smoke sheet rubber is main material, sizing material can be made to have elasticity is higher, heat-dissipating is lower, good over-all properties; Silane coupling agent, thermo-stabilizer and anti-recovery agent is added in formula, cross-linked rubber can be made to have good thermostability and anti-reversion behaviour, tyre ring reinforcement sizing material rubber when high temperature is not degraded or few degraded, significantly can improve the resistance toheat of the reinforcement glue when the condition of high temperature; Add cis-1,4-polybutadiene rubber, universal carbon black, cross-linked rubber can be made to have high elasticity and low heat-dissipating; Add the zinc oxide of higher dosage, sizing material can be made to have good heat conductivility.This sizing material is used in large aerospace tire, and tire is large in load, air pressure is low, tyre bead portion stressed large, be out of shape large working conditions under, there will not be the quality problems such as come to nothing in tyre bead inside, breach, tyre bead are quick-fried, tire used safety.
Accompanying drawing explanation
Fig. 1 is the longitudinal cutting structure schematic diagram being provided with tyre ring reinforcement glue aircraft tyre in embodiment.
In figure, 1. tread rubber 2. strengthening course 3. casingply 4. air retaining wall 5. sidewall rubber 6. tyre ring reinforcement glue-line 7. wheel rim.
Embodiment
Below in conjunction with drawings and Examples, content of the present invention is further elaborated, but is not limitation of the invention.
Embodiment:
With reference to Fig. 1, a kind of aircraft tyre being provided with tyre ring reinforcement glue, comprise tread rubber 1, strengthening course 2, casingply 3, air retaining wall 4 and sidewall rubber 5, also comprise tyre ring reinforcement glue-line 6, described tyre ring reinforcement glue-line 6 is arranged between the casingply 3 on tire bead top and sidewall rubber 5, curved shape.
Particularly, described tyre ring reinforcement glue-line 6 is arranged on wheel rim top, the horizontal bottom of tire centerline of wheel rim 7, is clipped between casingply 3 and sidewall rubber 5, and tyre ring reinforcement glue-line 6 and casingply 3, sidewall rubber 5 splice.
Make the tyre ring reinforcement glue of above-mentioned tyre ring reinforcement glue-line 6, its formula is made up of the raw material of following weight parts ratio:
The formula of the present embodiment is, the weight proportion of each raw material is:
After batching, by mixer mixing, produce rubber unvulcanizate, by the mode that forcing machine is extruded, rubber unvulcanizate is made tyre ring reinforcement glue work in-process, tyre ring reinforcement glue work in-process are affixed on tyre bead top by forming machine, make green tyre, and by vulcanizer, the sulfuration of tire base is become aircraft tyre finished product.
By formulating of recipe, use in tyre ring reinforcement glue formula have that heat-dissipating is lower, the higher feature of elasticity 1
#smoke sheet rubber is main material, and sizing material can be made to have snappiness, low-heat-generation, good over-all properties; Silane coupling agent, thermo-stabilizer and anti-recovery agent is added in formula, cross-linked rubber can be made to have good thermostability and anti-reversion behaviour, tyre ring reinforcement sizing material rubber when high temperature is not degraded or few degraded, significantly can improve the resistance toheat of the reinforcement glue when the condition of high temperature; Add cis-1,4-polybutadiene rubber, universal carbon black, cross-linked rubber can be made to have high elasticity and low heat-dissipating; Add the zinc oxide of higher dosage, sizing material can be made to have good heat conductivility.In addition, by the reasonable disposition of other component in formula, the hardness and vulcanization rate that tyre ring reinforcement glue are had match with adjacent component.
This tyre ring reinforcement glue is used for large aerospace tire, at a high speed, highly to carry, under hypobaric working conditions, tire bead top stressed large, distortion is large, deformation frequencies is high, tyre ring reinforcement glue plays buffering and endergonic effect, and because the heat-dissipating of sizing material is low, Heat stability is good, make tyre bead upper temp relatively low, this position sizing material there will not be sizing material melting, the quality problems such as come to nothing in inside, breach, tire used safety.
Sizing material specific performance is in table 1:
Table 1 properties of rubber
Aircraft tyre commonly uses the rebound value of sidewall rubber 30 ~ 36%, and compression fatigue heat-dissipating is at 22 ~ 26 DEG C, and rheometer torque curvilinear motion rate (165 DEG C × 60min) is greater than-20%.Can find out from the properties of rubber of table 1, the rebound value of this tyre ring reinforcement glue is high, compression fatigue heat-dissipating is low, Heat stability is good.Tyre ring reinforcement glue high for elasticity is arranged at tire bead top, and under the working conditions stressed greatly on tyre bead top, distortion is large, deformation frequencies is high, tyre ring reinforcement glue can play buffering and endergonic effect; Because the heat-dissipating of tyre ring reinforcement glue is low, make tyre bead upper temp relatively low; Because of tyre ring reinforcement glue Heat stability is good, the quality problems such as this position sizing material there will not be sizing material melting, come to nothing in inside, breach.The above performance characteristics of tyre ring reinforcement glue, when can make large aerospace tire used, tyre bead portion is functional, use safety.
This aircraft tyre has set up snappiness, low-heat-generation and heat-resisting good aircraft tire bead reinforcement glue, and this reinforcement glue is with 1
#smoke sheet rubber is main material, also has cis-1,4-polybutadiene rubber, universal carbon black, silane coupling agent, thermo-stabilizer, anti-recovery agent, zinc oxide to be that main subsidiary material are made by formulation ratio.Large aerospace tire at a high speed, highly to carry, use under hypobaric condition time, because speed is high, load is large and air pressure is lower, tire bead top stressed large, distortion is large, deformation frequencies height time, the temperature of tyre bead inside is high, is easy to occur the quality problems such as sizing material melting, cord anti-package termination and sizing material are thrown off, tyre bead top breach.The tyre ring reinforcement glue-line with snappiness, low-heat-generation, good thermotolerance and good heat conductivility is set between the casingply and sidewall rubber on large aerospace tire bead top, buffering and endergonic effect can be played, heat-dissipating simultaneously because of tyre ring reinforcement glue is low good with resistance toheat, make tyre bead upper temp relatively low, there will not be sizing material melting and tree lace to throw off phenomenon.
