Abstract
The present invention relates to field of rubber technology, it is specifically a kind of to be used for standard testing Tire tread rubber composition, it is characterized in that, include the butadiene rubber of 35 70 parts by weight, the natural rubber of 30 65 parts by weight, 30 60 parts by weight of carbon black per, 5 20 parts by weight filling oil and 1.5 2.5 parts by weight sulphur, and other tyre industries are coordinated often to 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 and snowfield grasp 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 a kind of 225/75R16C TR675 specification standards test
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 and snowfield grasp Performance Evaluation, can be used for it
He assesses, 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：One kind is used for standard testing tire tread rubber group
Compound, it is characterised in that include the butadiene rubber of 35-70 parts by weight, the natural rubber of 30-65 parts by weight, coordinate 30-60 weight
Part carbon black, 5-20 parts by weight filling oil and 1.5-2.5 parts by weight sulphur, and other tyre industries often use rubber chemicals.
Preferably, the natural rubber is to mark glue from Thailand 20#, it is 40-65 parts by weight.
The butadiene rubber is from BR9000, is 35-60 parts by weight
The carbon black is 35-55 parts by weight.
The filling oil is RAE oil, is 10-15 parts by weight.
The sulphur is common Cosan, is 1.75-2.25 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 and snowfield grasp Performance Evaluation, can be used for other assessments, such as
Wear hardness, the resistive energy of rolling, pavement friction characteristic, noise etc..
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 carbon black, age resistor etc. except sulphur, accelerator
Outside raw material, press bolt 30s, add environment protection oil, press bolt 30s, carry bolt, pressure bolt to 165 DEG C of dumpings again.
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
165 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 stills remain in 17.0Mpa or so, and 100%
Stress at definite elongation is maintained at 7.0Mpa, and hardness is maintained at 65 degree or so.Dynamic mechanical test result shows that 0 DEG C of tan δ is kept
0.10 or so.Show the good mechanical properties of sizing material of the present invention.
According to the method for real train test, wetland is carried out to finished product tire and snowfield grasps the test of index.It is with embodiment 2
Example, carry out the trial-production of two-wheeled finished product tire.Wetland and snowfield grasp index results as shown in table three, table four.
It is respectively 1.00,1.01,1.02,1.02 that the snowfield of four groups of tires, which grasps index, and the wetland of three groups of tires grasps finger
Number is 1.02,1.05,1.05 respectively.The tyre performance of two-wheeled trial-production is more or less the same, and illustrates steady quality, the standard testing tire
Have the function that grasp performance to the wetland and snowfield 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.
