Abstract
The present invention relates to field of rubber technology, specifically a kind of rubber composition for standard testing tire tread, it is characterised in that：Include the butadiene rubber of 5 15 parts by weight, the natural rubber of 5 25 parts by weight and 60 90 parts by weight butadiene-styrene rubber, coordinate 50 75 parts by weight of carbon black per, 10 30 parts by weight filling oil and 1.5 2.5 parts by weight sulphur, and tyre industry often to use the rubber chemicals of parts by weight.This invention ensures that the reliability of the mechanical property such as the tensile strength of sizing material, stress at definite elongation, there is the tire prepared simultaneously scientific and effective snowfield to grasp the effect of Performance Evaluation, it can be used for other assessments, such as wear hardness, the resistive energy of rolling, pavement friction characteristic, noise, the rubber composition at tire tread position is tested for 195/75R14 TE305 specification standards.
Description
Technical field
It is a kind of rubber group for standard testing tire tread position the present invention relates to a kind of rubber for tire technical field
The rubber composition at compound, specifically 195/75R14 TE305 specification standards test tire tread position.
Background technology
It is well known that ISO and international metering vocabulary are to " standard substance（Reference material）" give and define：" have one
Kind or it is a variety of enough the uniform characteristic determined well, to calibrating measuring device, evaluate measuring method or give material 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, are the necessary conditions of the uniformity and comparativity that ensure measurement result.
In the world, the outdoor test of tire, such as wetland and snowfield grasp performance test, are carried out using standard testing tire
Method of comparison, i.e., the standard testing tire for stablizing, meeting specification using one group of performance is used as normative reference, the same standard testing of other tires
Tire carries out the contrast test with the conditions of on the road surface of standardization.Its performance index is tested for test tire with 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
There is provided used to global each Tire testing company after its plant produced specified.Cause standard testing tire procurement cycle length,
Price is high, seriously constrains the progress of China's Tire testing and certification work.
To break trade monopoly, preferably promote the development of China's tyre industry, according to the market demand, China has carried out mark
The R＆D work of quasi- test tire, has filled up the blank of tyre industry.Standard tire has the class tire of C1, C2 and C3 tri-.Wherein
C1 class tires have 225/60R16 TC105 and 195/75R14 TE305.
Tyre crown position is directly contacted with ground, therefore, and the performance of tyre surface formula grasps performance to the snowfield of tire and risen
To crucial effect.Tyre surface formula is adjusted, the snowfield that can effectively adjust tire grasps index.
The content of the invention
The purpose of the present invention is exactly that there is provided a kind of 195/75R14 TE305 specification marks in order to overcome existing technical deficiency
There is the rubber composition at quasi- test tire tread position, the tire of preparation scientific and effective snowfield to grasp the work of Performance Evaluation
With, it can be used for other and assess, such as wear hardness, the resistive energy of rolling, pavement friction characteristic, noise.
The present invention solve above-mentioned technical problem use technical scheme be：A kind of rubber for standard testing tire tread
Composition, it is characterised in that：Include the butadiene rubber of 5-15 parts by weight, the natural rubber and 60-90 parts by weight of 5-25 parts by weight
Butadiene-styrene rubber, coordinates 50-75 parts by weight of carbon black per, 10-30 parts by weight filling oil and 1.5-2.5 parts by weight sulphur, and tire row
Industry often uses the rubber chemicals of parts by weight.
Preferably, the natural rubber is to mark glue from Thailand 20#, it is 5-20 parts by weight.
Preferably, the butadiene-styrene rubber is emulsion polymerized styrene butadiene rubber, it is 60-85 parts by weight.
Preferably, the carbon black is selects N375, it is 50-70 parts by weight.
Preferably, the filling oil is RAE oil, it is 15-30 parts by weight.
The beneficial effects of the invention are as follows, it is ensured that the reliability of the mechanical property such as tensile strength, stress at definite elongation of sizing material, together
When the effect that there is scientific and effective snowfield to grasp Performance Evaluation of the tire for preparing, can be used for other assessments, such as abrasivity
, resistive energy, pavement friction characteristic, noise etc. can be rolled, tire tread position is tested for 195/75R14 TE305 specification standards
Rubber composition.
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, specifically
Step is as follows：
One section of milling maternal rubber：Natural gum is added in banbury GK400, oil removing, sulphur, the accelerator such as carbon black, age resistor is added
Outside raw material, press bolt 30s, plus environment protection oil presses bolt 30s, and bolt, pressure bolt to 155 DEG C of dumpings are carried again.
Two sections of milling maternal rubbers：One section of rubber master batch is added, pressure bolt keeps 30s, carries and press bolt 30s after bolt again, carries and presses bolt extremely after bolt
155 DEG C of dumpings.
Finished composition is kneaded：Two-stage mixing glue, sulphur and accelerator are added, pressure bolt keeps 30s, carries and bolt is pressed after bolt to 105 DEG C
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 stills remain in 20.0Mpa or so, 100%
Stress at definite elongation is maintained at 3Mpa, and 300% stress at definite elongation reaches 13.9MPa, and hardness is maintained at 65 degree or so, and tearing strength is 54
KN/m.Show the good mechanical properties of sizing material of the present invention.
According to the method for real train test, the test that snowfield grasps index is carried out to finished product tire.By taking embodiment 2 as an example, trial-production
Four composition product tires, every group of 4 tires, test data is as shown in Table 3.The snowfield of four groups of tires grasp index be respectively 1.01,
1.03rd, 1.02,1.03, illustrate that tyre performance is stable, the standard testing tire grasps performance with the snowfield to other tires and entered
The effect that row is assessed.
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.
