Abstract
The present invention relates to field of rubber technology, a kind of specifically Tire tread rubber composition for standard testing, it is characterized in that, include the butadiene-styrene rubber of 100 parts by weight, coordinate the carbon black of 30 70 parts by weight, 20 60 parts by weight white carbons, the organosilicon mixture of 5 12 parts by weight, 10 40 parts by weight filling oil and 1.5 3.5 parts by weight sulphur, and other tyre industries often use rubber chemicals.This invention ensures that the reliability of the mechanical property such as the tensile strength of sizing material, stress at definite elongation, the tire prepared simultaneously has the function that scientific and effective wetland grasps Performance Evaluation, it can be used for other assessments, such as wear hardness, the resistive energy of rolling, pavement friction characteristic, noise.
Description
Technical field
The present invention relates to rubber for tire technical field, specifically one kind is related to the survey of 225/60R16TC105 specification standards
Try the rubber composition at tire tread position.
Background technology
It is well known that ISO and international metering vocabulary are given to " standard substance (reference material) " and defined：" have one
Kind or a variety of uniform characteristics determined well enough, to calibrating measuring device, evaluation measuring method or give material to assign
A kind of material or material of value ", standard testing tire is the standard substance in tyre industry, and it serves primarily in tyre performance survey
Examination and the implementation and application of grade scale, it is the necessary condition of the uniformity and comparativity that ensure measurement result.
In the world, the outdoor test of tire, as wetland and snowfield grasp performance test, carried out using standard testing tire
Method of comparison, i.e., normative reference, the same standard testing of other tires are used as using one group of stable performance, the standard testing tire for meeting specification
Tire carries out the contrast test with the conditions of on the road surface of standardization.Its performance index is tested for test tire and standard tire
The ratio of data.
At present, the standard testing tire used in the world is that company of Michelin produces without competition.And sought unity of standard according to it, by
After its plant produced specified, there is provided to the whole world, each Tire testing company uses.Cause the procurement cycle of standard testing tire it is long,
Price is high, seriously constrains the progress of China's Tire testing and certification work.
The content of the invention
The purpose of the present invention is exactly to overcome existing technical deficiency, there is provided a kind of tire tread for standard testing
Rubber composition, the tire of preparation have the function that scientific and effective wetland grasps Performance Evaluation, can be used for other assessments,
Such as wear hardness, the resistive energy of rolling, pavement friction characteristic, noise.
The present invention solves the technical scheme that above-mentioned technical problem uses：A kind of tire tread rubber for standard testing
Composition, it is characterised in that include the butadiene-styrene rubber of 100 parts by weight, coordinate the carbon black of 30-70 parts by weight, 20-60 parts by weight are white
Carbon black, the organosilicon mixture of 5-12 parts by weight, 10-40 parts by weight filling oil and 1.5-3.5 parts by weight sulphur, and other wheels
Tire industry often uses rubber chemicals.
Preferably, the white carbon is from 1165MP, it is 25-55 parts by weight.
The carbon black is 35-65 parts by weight.
The organosilicon mixture is 5-10 parts by weight.
The filling oil is RAE oil, is 15-35 parts by weight.
The sulphur is common Cosan, is 1.5-3.0 parts by weight.
The invention has the advantages that the reliability of the mechanical properties such as the tensile strength of sizing material, stress at definite elongation is ensure that, together
When the tire for preparing have the function that scientific and effective wetland grasps Performance Evaluation, can be used for other assessments, such as abrasivity
, resistive energy, pavement friction characteristic, noise etc. can be rolled.
Embodiment
With reference to embodiment, the present invention will be further described：
It can be prepared according to existing conventional techniques using raw material components of the present invention, content and tire production process,
Comprise the following steps that：
One section of milling maternal rubber：Natural gum is added in banbury GK400, adds the sulphur removal such as carbon black, white carbon, age resistor
Raw material outside sulphur, accelerator, bolt 30s is pressed, adds environment protection oil, press bolt 30s, carry bolt, pressure bolt again, 130 DEG C of constant temperature 150s, extremely
145 DEG C of dumpings.
Two sections of milling maternal rubbers：One section of rubber master batch is added, pressure bolt keeps 30s, bolt 30s is pressed again after carrying bolt, and bolt is pressed extremely after carrying bolt
145 DEG C of dumpings.
Finished composition is kneaded：Two-stage mixing glue, sulphur and accelerator are added, pressure bolt keeps 30s, and bolt is pressed to 105 DEG C after carrying bolt
Dumping.
In order to verify the reliability of effect of the present invention, with reference to comparative example, the present invention is described in detail, but this hair
It is bright to be not limited to these embodiments.Cooperation table and physical and mechanical properties test result are shown in Table one, table two.
As can be seen from Table II, embodiment is compared with comparative example, and tensile strength is more than 18.0Mpa or so, and 100% stretch surely should
Power is maintained at 6.0Mpa or so, and hardness is maintained at 67 degree or so.Dynamic mechanical test result shows that 0 DEG C of tan δ is more than
0.370.Show the good mechanical properties of sizing material of the present invention.
According to the method for real train test, the test that wetland grasps index is carried out to finished product tire.By taking embodiment 3 as an example, carry out
Two-wheeled finished product tire is manufactured experimently.Wetland grasps index results as shown in Table 3.
It is 1.03,1.04,1.04,1.03 respectively that the wetland of four groups of tires, which grasps index,.The tyre performance phase of two-wheeled trial-production
It is poor little, illustrate steady quality, the standard testing tire has the function that grasp performance to the wetland of other tires assesses.
Based on above test result, the tire of embodiment of the present invention can be very good to play as standard testing tire
It is acted on.
