Abstract
The invention relates to a formula of a motorcycle tire crown. The motorcycle tire crown comprises the following raw materials in part by weight: 50 parts of natural rubber (NR), 35 parts of styrene butadiene rubber (SBR) 1712, 75 parts of reclaimed rubber, 3.5 parts of nano zinc oxide, 2 parts of stearic acid, 1.8 parts of antioxidant 4010NA, 1 part of antioxidant RD, 1.2 parts of antioxidant Ble-w, 1.2 parts of paraffin, 8 parts of coumarone-indene resin, 31 parts of N330, 31 parts of N220, 10 parts of aromatic hydrocarbon oil, 2 parts of sulfur powder, 1.2 parts of accelerator CZ and 0.2 part of scorch retarder polyvinyl isobutyl ether (PVI). The motorcycle tire crown is high in performance, low in cost and high in operability.
Description
Technical field
The present invention relates to the rubber tyre field, be specifically related to a kind of formula of motorcycle tire crown.
Background technology
At present, design to motorcycle tyre crown high rigidity, high abrasion, high resistance puncture has been trend, production cost strengthens, and how keeps balance between the good colloidality energy of motorcycle tyre crown and cost, and obtaining larger income is the important problem of pendulum in face of the research staff.Crown and sidewall generally are to adopt unified prescription in the prior art, and such design is so that can't realize by integral extrusion technique of a side between the performance requriements on crown and sidewall.
Summary of the invention
The purpose of this invention is to provide a kind of motorcycle tyre crown prescription, namely save cost and kept again good colloidality energy.
The technical scheme of taking for the present invention that achieves the above object is:
A kind of formula of motorcycle tire crown comprises the raw material of following weight parts:
NR 50；
SBR1712 35；
Reclaimed rubber 75;
Nano zine oxide 3.5;
Stearic acid 2;
Anti-4010NA 1.8;
Anti-RD 1;
Anti-Ble-w 1.2;
Paraffin 1.2;
Coumarone indene resin 8;
N330， 31；
N220， 31；
Aromatic hydrocarbon oil 10;
SULPHUR POWDER 2;
Short CZ 1.2;
Scorch retarder PVI 0.2.
According to above prescription, extrude crown by hot-feed extruder, the physical index that records and
The rheology index is as follows:
Physical index (160 degree * 10min)
| Tensile strength at yield mpa | 12.5 |
| Tensile yield % | 480 |
| 300% tensile modulus mpa | 6 |
| Hardness Shao A | 72 |
Rheology index (170 degree * 3min)
| T10 S | 0:56 |
| T90 S | 1:50 |
| ML | 20.000 |
| MH | 35.000 |
Performance formula of the present invention is good, cost is low, workable, with the separately design of the prescription on crown and sidewall, at last crown and sidewall are carried out heat posted, can realize the organic unity of cost, performance, technique.
Embodiment
Following examples are used for explanation the present invention, but are not used for limiting the scope of the invention.
Embodiment 1:
A kind of formula of motorcycle tire crown comprises the raw material of following weight parts:

Anti-4010NA 1.8;
Anti-RD 1;
Anti-Ble-w 1.2;
Paraffin 1.2;
Coumarone indene resin 8;
N330， 31；
N220， 31；
Aromatic hydrocarbon oil 10;
SULPHUR POWDER 2;
Short CZ 1.2;
Scorch retarder PVI 0.2.
According to above prescription, extrude crown by hot-feed extruder, the physical index that records and
The rheology index is as follows:
Physical index (160 degree * 10min)
| Tensile strength at yield mpa | 12.5 |
| Tensile yield % | 480 |
| 300% tensile modulus mpa | 6 |
| Hardness Shao A | 72 |
Rheology index (170 degree * 3min)
| T10 S | 0:56 |
| T90 S | 1:50 |
| ML | 20.000 |
| MH | 35.000 |
Performance formula of the present invention is good, cost is low, workable, with the separately design of the prescription on crown and sidewall, at last crown and sidewall are carried out heat posted, can realize the organic unity of cost, performance, technique.
