Description
Technical field
The present invention relates to a kind of foaming tire tread rubber and preparation method thereof, belong to tire formulation technical field.
Background technology
In the process of moving, tyre surface directly contacts tire with road surface, and periodic compression causes tyre crown to continue
Heating, and shoulder sky finally occurs, is preced with empty destroy.The factor for influencing crown heating divides external factor and internal factor.External factor
It is related to travel speed, loading capacity, running time and the pavement behavior of tire；Internal factor is related to the viscoelastic of tire tread formula
Heat size, structure type of tread contour etc..Under conditions of external condition is certain, the viscoplasticity of tread mix is to heat
There is major contribution.
For tread rubber, heat, wet and slippery and wearability are traditional " devil " triangles, excellent wear-resisting in order to reach
Property, it usually needs high-specific surface area, super-normal structure black in filling, and the addition of this filler causes the heat higher of sizing material.Rubber
Glue is the non-conductor of heat, and the arrangement of tyre crown internal sizes is close, is unfavorable for heat conduction, also cause temperature constantly to be gathered,
Rise.Middle-long distance vacuum tyre, bearing type tire, the architects of high speed half steel tire are usually adjusted by decorative pattern, for example increased
The effective heat dissipation area of texture mapping, shoulder caused by reducing heat using the wide or more shallow pattern depth of narrower tread is empty,
The empty symptom of hat.Although this mode improves the heat dissipation performance of sizing material to a certain extent, but has damaged the wear-resisting of tyre surface
Performance.Moreover, shoulder is empty, hat sky is high still in three guarantees tire ratio, and the heat dissipation problem of crown is still tire
Bottleneck.
The content of the invention
Present invention aims to solve the deficiencies of the prior art, and provides a kind of a kind of foaming tire tyre surface and preparation method；Pass through
The mode of foaming increases effective heat dissipation area inside and out crown.On the premise of wearability is not sacrificed, shoulder sky, hat are reduced
Empty occurrence frequency, lifts tire quality.
Technical scheme, foaming tire tread rubber, formula rate are as follows by weight：100 parts of rubber, carbon black
40 ~ 53 parts, 0 ~ 20 part of white carbon, 2 ~ 5 parts of ZnO, 2 ~ 4 parts of stearic acid, 1.5 ~ 2 parts of p phenylenediamine type antioxidant, ketoamine class prevent always
2 ~ 3 parts of agent, 1 ~ 1.3 part of sulphur, 1.5 ~ 2 parts of sulfenamide type accelerators, 0.2 ~ 0.5 part of anti-scorching agent CTP, foaming agent 0.3 ~ 5
Part；
It first adds rubber, carbon black, white carbon, ZnO, stearic acid, p phenylenediamine type antioxidant and ketone amines antioxidants close
In mill, milling maternal rubber is carried out；Sulphur, sulfenamide type accelerators, anti-scorching agent CTP and foaming agent are then added, is finally obtained
Product foaming tire tread rubber.
Further, the rubber is the mixed of one or more of materials in natural rubber, butadiene rubber and butadiene-styrene rubber
Compound.
Further, the carbon black is the mixture of one or several kinds of materials in N234, N220, N134 and N115.
Further, the foaming agent is nitroso compound such as blowing agent H or other blowing temperatures and vulcanization temperature
Spend the organic and inorganic foaming agent to match.

~ 4 parts, 1.5 ~ 2 parts of p phenylenediamine type antioxidant, in 2 ~ 3 parts of addition mixers of ketone amines antioxidants, keep fill factor 65% ~
75%, the dumping under the conditions of 155 ~ 165 DEG C, the refining glue time is 1 ~ 3 min；It is 5 ~ 10mm that the bottom sheet of mixer, which controls film stock thickness,
One section of rubber master batch is prepared；
B, two sections of rubber master batch refining glues：One section of rubber master batch obtained by step a is added in mixer according to 65% ~ 75% fill factor and is continued
It is kneaded, dump temperature is 155 ~ 160 DEG C, and the refining glue time is 1 ~ 3min；
（2）Refining eventually：By step（1）Gained rubber master batch is added in mixer, and the fill factor of mixer is 70% ~ 80%, is continuously added
1 ~ 1.3 part of sulphur, 1.5 ~ 2 parts of sulfenamide type accelerators, 0.2 ~ 0.5 part of anti-scorching agent CTP, 0.3 ~ 5 part of foaming agent, during refining glue
Between be 2 ~ 3min, dump temperature is 85 ~ 95 DEG C；Mixer bottom sheet and to control thickness be 5 ~ 7mm, obtains foaming tire tread rubber.
Further, step（1）Further include three sections of masterbatchings：By step（1）Two sections of masterbatch are according to 65% ~ 75% obtained by b
Fill factor is added in mixer and is kneaded, and dump temperature is 155 ~ 160 DEG C, and the refining glue time is 1 ~ 3min.
Further, step（2）Gained foaming tread mix obtains finished product tyre surface by extrusion, shaping, vulcanization process, into
The aperture of product tread rubber is 1 ~ 3mm, is evenly distributed.
Beneficial effects of the present invention：The present invention by added in tyre surface formula with match organic of curingprocess rate or
Inorganic foaming agent such as blowing agent H, increases effective heat dissipation area inside crown and outside tyre surface in a manner of foaming, reduces heat
Shoulder caused by accumulation is empty, the empty phenomenon of hat.This design method leaves bigger operating space to structure design personnel, such as can
With wide by increasing pattern depth, raising tread, the distance travelled of increase decorative pattern saturation degree etc. measure lifting tire, lifting
The quality of tire.In addition, the tyre surface of this foaming can also improve the noise of tire, the wet-sliding resistant performance of tire is lifted.
