Abstract
The invention discloses a truck tire tread base rubber, which comprises the following components by weight: 0-20 parts of natural rubber, 30-45 parts of butadiene rubber, 35-55 parts of styrene butadiene rubber, 1.8-2.2 parts of stearic acid, 3-5 parts of zinc oxide, 1.8-2.2 parts of microcrystalline wax, 2.5-3 parts of an antioxidant, 11-12 parts of operating oil, 60-65 parts of hard carbon, 0.6-0.7 part of a scorch retarder, 1.2-1.3 parts of a promoter and 1.6-1.8 parts of sulfur. The truck tire tread produced by the rubber provided by the invention has bright dark color, no crack, no bubble, and tread hardness of not less than 60 degrees.
Description
Technical field
The invention belongs to tread rubber of automobile tires technical field, be specifically related to a kind of heavy-duty truck tyre tread base rubber.
Background technology
Tread rubber be outermost tyre layers contact with road surface and surface print a dapple layer sizing.Tire can be made to have tractive force, cushion impact when travelling and wave, preventing cutting and piercing through of cord ply.Require wear resistance, the fatigue performance with height, good ageing-resistant performance, higher tensile strength, elasticity and obdurability, and heat generation low when travelling.The rubber manufactures such as available natural rubber, styrene-butadiene rubber(SBR), cis polyisoprene rubber and cis-1,4-polybutadiene rubber.A large amount of carbon black is often added, to improve its physical and mechanical properties in sizing material.
Summary of the invention
The object of the invention is to, provide a kind of heavy-duty truck tyre tread base rubber, the heavy-duty truck tyre tread color and luster using sizing material of the present invention to produce is pitch-dark vivid, and without breach, bubble-free, tyre surface hardness is not less than 60 degree.
Heavy-duty truck tyre tread base rubber provided by the invention, its components in mass portion proportioning is as follows:
Natural rubber 0-20 parts,
Cis-1,4-polybutadiene rubber 30-45 parts,
35-55 parts, styrene-butadiene rubber(SBR),
Stearic acid 1.8-2.2 parts,
3-5 parts, zinc oxide,
Microcrystalline Wax 1.8-2.2 parts,
2.5-3 parts, anti-aging agent,
Process oil 11-12 parts,
Hard (carbon) black 60-65 parts,
Scorch retarder 0.6-0.7 part,
Promotor 1.2-1.3 parts,
1.6-1.8 parts, sulphur.
Heavy-duty truck tyre tread base rubber provided by the invention, its beneficial effect is: the heavy-duty truck tyre tread color and luster using sizing material of the present invention to produce is pitch-dark vivid, and without breach, bubble-free, tyre surface hardness is not less than 60 degree.
Embodiment
Below in conjunction with an embodiment, heavy-duty truck tyre tread base rubber provided by the invention is described in detail.
Embodiment
The heavy-duty truck tyre tread base rubber of the present embodiment, its components in mass portion proportioning is as follows:
