Abstract
Rubber system of the present invention is used in combination using natural rubber and butadiene rubber.Reinforcement system is using STERLIN V (SV) carbon blacks and uses part white carbon, the compounding agents such as addition silane coupling agent KH 560, adhesive SL 3090, adhesion promoter AIR 201, adhesion promoter AIR 1 in formula.The body piles kiss-coating hardness of the present invention, stress at definite elongation are relatively low, and sizing material is softer, and body piles kiss-coating is not just allowed to be also easy to produce breach when repeated deformation；It is suitable for the high performance requirement of the following new architecture tire high speed, high load, renovation number；Sizing material and nylon cord adhesive strength are high before aging, after aging, and fatigue performance is good, heat is low, rebound value is high, hysteresis loss is small, and carcass delamination layer, bulge, sidewall can be prevented quick-fried, improves the service life and security performance of radial air tire.
Description
Technical field
The present invention relates to technical field of polymer materials, specifically radial air tire carcass layer kiss-coating.
Background technology
Radial air tire carcass layer is the skeleton of tire, other than the air pressure for bearing tire, still suffers from tire
Load and the external impact force of buffering, meridian tyre body layer cord radially arrange, sidewall radial deformation compares oblique
Tire is big by 10%~30%, and in addition radial air tyre rebuilding number requires high, and existing radial air tire is due to speed
Top load is big, and sidewall position distortions are big and many-sided reason such as kiss-coating raw material used and material combination causes tire high speed to be rolled
It is quick-fried etc. that it is susceptible to carcass delamination layer, bulge, sidewall when dynamic, influences service life and safety.
Invention content
That the object of the present invention is to provide a kind of bond properties is good, fatigue performance is good, heat is low, hysteresis loss is small, rebound
It is worth the radial air tire carcass layer kiss-coating of the features such as high.
Realizing the technical solution of the object of the invention is：
A kind of radial air tire carcass layer kiss-coating is to pass through two sections of mixer by following raw materials by weight ratio
Be kneaded, produce rubber compound, rolled with tri-roll press machine and rubberized cord, body piles bandage is made in slice applying machine bench, at
It is molded on type machine, green tyre is made, and become tire finished product by vulcanizer vulcanizes tire base；

Rubber system of the present invention is used in combination using natural rubber and butadiene rubber, and natural rubber has tensile strength high, elastic
Greatly, heat is low, elongation is high, the good feature of processing performance, and the fatigue performance that butadiene rubber is conducive to improve sizing material is added, subtracts
The hysteresis loss of small sizing material.Reinforcement system is using STERLIN V (SV) carbon blacks and with part white carbon, STERLIN V (SV) charcoal
Black is a kind of semi-reinforcing hydrocarbon black, has the characteristics that easily dispersion, impurity content are few, are added the body piles of STERLIN V (SV) carbon black
Kiss-coating fatigue performance is good, heat is low, hysteresis loss is small；White carbon, which is added, can reduce the heat of sizing material, improve sizing material and brocade
The adhesive strength of synthetic fibre cord.Silane coupling agent KH-560 is added in formula, the bonding with nylon cord after sizing material aging can be improved
Intensity；Adhesive SL-3090 is added in formula, adhesion promoter AIR-201, AIR-1 improve the bond properties of sizing material and cord.
Preventing aging system is used in combination using p phenylenediamine type antioxidant 4020 and ketoamine class anti-aging agent RD, BLE, and antioxidant 4020 is old to hot oxygen etc.
Changing, there is excellent protective action, anti-aging agent RD to have the function of that the oxidation of rejection condition harshness and heat ageing, antioxidant BLE remove
Play the role of outside age inhibiting, while being conducive to the bonding of glue and line.Anti-recovery agent WK-901 is added, improves the anti-of sizing material
Recovery performance prevents body piles kiss-coating from reverting when being repeatedly remoulded vulcanization.
The present invention is a kind of radial air tire carcass layer kiss-coating, and specific performance is shown in Table 2. after tested
2 properties of rubber of table
Advantages of the present invention：
1. the body piles kiss-coating hardness of the present invention, stress at definite elongation are relatively low, sizing material is softer, and body piles kiss-coating is repeatedly
Just do not allow to be also easy to produce breach when deformation；
2. being suitable for the high performance requirement of the following new architecture tire high speed, high load, renovation number；Before aging, after aging
Sizing material is high with nylon cord adhesive strength, and fatigue performance is good, heat is low, rebound value is high, hysteresis loss is small, can prevent tire
Carcass delamination layer, bulge, sidewall are quick-fried, improve the service life and security performance of radial air tire.
Description of the drawings
Fig. 1 is that the comprehensive of tire cuts structural schematic diagram；
In figure：1 tread rubber, 2 belts, 3 shoulder wedges, 4 body piles kiss-coatings, 5 sidewalls, 6 tyre beads.
