Description
Technical field
The present invention relates to rubber for tire technical field, specifically a kind of multiple dedicated rim of the mouth of low pressure engineering radial tire
Protect glue rubber composition.
Background technique
It is well known that reducing the vibration in vehicle travel process to adapt to engineering truck market development demand, improves and drive
Comfort, my company 23.5R25 scale engineering radial tyre of mating market demands is compared with low pressure（60psi）Down in use, tire
Circle endurance quality reaches mating requirement.The standard pressure that the specification tyre operates normally is 650KPa, and 415 KPa are down in air pressure
（60psi）Shi Yunhang, tyre bead portion deformation is larger under low pressure.
Summary of the invention
The object of the invention is in order to overcome the above-mentioned deficiencies of the prior art, provide a kind of low pressure engineering radial tire
Glue rubber composition is protected in dedicated rim of the mouth, and tyre rim glue is warping strength, and guarantees certain wearability, can prevent because deforming, grinding
Larger caused tyre bead breach is damaged, the service life of tire is improved.
The present invention solve above-mentioned technical problem the technical solution adopted is that：A kind of dedicated rim of the mouth of low pressure engineering radial tire
Protect glue rubber composition, which is characterized in that raw material includes in parts by weight：
Natural gum 30~40,
Cis-butadiene cement 60~70,
Carbon black 60~65,
Zinc oxide 3~5,
Stearic acid 1~2,
Tackifying resin 1~2,
Function hydrocarbon resins 0~2,
RAE oil 0~6,
P-phenylenediamine anti-aging agent 2.25~2.75,
Quinoline type antioxidant 1.0~1.5,
Protection wax 1.5~2.0,
Sulphur 1.9~2,
Sulfenamide type accelerators 1.45~1.55,
Thiazole accelerator 0.9~1.0,
N- cyclohexylthiophthalimide 0.3~0.4.
The invention has the advantages that hardness is high, abrasion index is high, it is ensured that the wear-resisting property of tyre bead bead；It draws
It is high to stretch intensity, tearing strength, elongation, on the basis of improving tyre bead portion stretching, tear resistance, the change of tyre bead height can be improved
Performance is deflected under shape；The dedicated rim of the mouth rubber composition of invention is applied in engineering radial tire 23.5R25 units specification market, low
Air pressure（60psi）When condition operation, vehicle drive comfort, vehicle vibration, the endurance quality at tire bead position are all satisfied and match
Set requires.
Specific embodiment
The present invention will be further described with reference to the examples below：
The present invention uses the rubber system of certain part by weight natural rubber and butadiene rubber, and natural rubber green strength is high,
Elasticity is good for butadiene rubber, wear-resisting, warping strength, and obtained rubber composition tensile property is excellent, wear-resisting, warping strength to have excellent performance.
The present invention applies the carbon black of low filling weight part, and the RAE oil of certain part by weight is guaranteeing building rubber compound
On the basis of object hardness, wear-resisting property, elongation can be improved, improvement deflects performance.
The function hydrocarbon resins of present invention application certain part by weight, can be improved the tearing strength of rubber composition, and improvement is torn
Fragility energy.
For the reliability for confirming effect of the present invention, below with reference to examples illustrate the present invention, under standard pressure
The engineering radial tyre rim shield glue rubber composition and performance indexes used compares, but the invention is not limited to
These embodiments, are specifically shown in shown in the following table 1：
Embodiment rubber composition and former rubber composition physical mechanical property contrast test data such as the following table 2：
As seen from Table 2：Compared with former composition sizing material, the tensile strength of 1 sizing material of embodiment, elongation are higher, flexible resistance energy
It is good；Hardness is suitable, thus tyre bead portion rigid phase is worked as；DIN wear volume amount is suitable, and wear-resisting property is consistent；Tearing strength
Slightly increase.
Compared with former composition sizing material, the hardness of 2 sizing material of embodiment is slightly lower, and rigidity slightly declines；DIN wear volume amount compared with
It is low, thus wear-resisting property increases；Other performance is substantially suitable.
Increase performance to verify the breach of rim of the mouth rubber composition sizing material, carries out breach and increase contrast test, it is specific to test
As a result such as the following table 3：
Increasing data overall trend from breach can be seen that breach growth rate：1 < embodiment of embodiment, 2 < original composition；It is real
The breach growth rate for applying example 1 is most slow.
Different components sizing material is carried out on rubber fatigue cracking tester deflects tired contrast test, contrast test result
It see the table below 4：
Breach test result is deflected as can be seen from Table 4：Embodiment 1 is better than former composition, i.e. 1 > of embodiment better than embodiment 2
2 > original composition of embodiment
To sum up, glue rubber composition preferred embodiment 1 is protected in the dedicated rim of the mouth of the low pressure engineering radial tire of invention, the advantage is that：
On the basis of keeping tyre bead rigidity, tensile property is high, flexible resistance energy is good；Volume worn amount is low, and wear-resisting property is excellent；Lancinating
Can be high, it ensure that when low-atmosphere in tyre operation, high deformation tyre bead portion deflects deformation performance, Life of Tyre can be improved.
The dedicated rim of the mouth rubber composition embodiment 1 of low pressure invented using this produces 23.5R25 TB516 specification wheel
Tire carries out mating market entrucking under the durable comparative test of interior lathe tyre bead, low pressure under low pressure with the normal tire of the specification
Performance evaluation contrast test, reference examples and embodiment test tire test environment are identical as test condition, and contrast test data are specific
As shown in table 5 below：
The 23.5R25 TB516 specification tyre low pressure 415KPa produced using different rim of the mouth rubber compositions（Work normally gas
Pressure：650KPa）Under operating condition, the driver comfort and Vehicular vibration that carry out original equipment manufacturer requirement improve the subjective assessment of situation,
Specific test evaluation comparing result such as the following table 6：
Glue rubber composition is protected in the dedicated rim of the mouth of the low pressure engineering radial tire of invention, in the base for guaranteeing tyre bead rigidity, wear-resisting property
On plinth, tyre bead bead can be improved deflects performance, when avoiding low-atmosphere in tyre operation, because the deformation of tyre bead rim of the mouth is seriously drawn
The tyre bead circumferential direction breach and tyre bead delamination problems risen；The endurance test of lathe tyre bead is relaxed by mating requirement, the driving of conveyance vehicle
The subjective assessment that adaptive and vehicle vibration situation pass through original equipment manufacturer.
