Description
Technical field
The present invention relates to a kind of high-performance environment-friendly half green tire formula, belong to tire manufacturing techniques field.
Background technology
The requirement of social development to tyre performance is more and more higher, and Jian is complete, green, environmental protection, intelligence become in the green tire of one the new trend that world's tire develops.The major advantage of green tire is as follows:
1, high-environmental: conventional tire is owing to the addition of the rubber ingredients of carcinogenesis, they distribute in atmosphere along with treadwear, severe contamination environment, there is several hundred million tires to go out of use in the world every year simultaneously, they not only occupy large quantity space, and be difficult to decompose, great threat is caused to environment, is called " black pollution " by people.Along with improving constantly of people's environmental consciousness, while the reduction rolling resistance that keeps punching, start to pay attention to using material free from environmental pollution to manufacture tire, and made great efforts the actual service life of prolongation tire, to reduce the quantity of junked tire.After a large amount of automobiles uses green tire, great function is produced to fuel-economizing and decreasing pollution.The widespread use of green tire will save millions of barrels of oil for the whole world is annual, and significantly reduce the quantity discharged of CO.
2, low consumption: black tire accustomed to using makes with the synthetic rubber of standard and natural rubber, under the condition that running car temperature raises, the stuctures and properties of its protective material all changes, and the resistance of wheel rolling is also in increase simultaneously.Green tire, compared with conventional tyre, alleviates tire weight, decreases the energy consumption (hysteresis loss) of matrix material.So, green tire is compared with the tire of equivalent specifications, and rolling resistance can reduce 22%-35%, and therefore reduces automobile fuel consumption 3%-8%, the quantity discharged of automobile CO is declined to some extent, and other performances such as abrasion performance, low noise, dry wet road surface gripping power etc. all keep good level.
3, super safety: green tire, by optimizing carcass design, improves automobile at the earth-catching property of smooth road with excellent elasticity tyre surface, make driving more steadily, stopping distance is shorter, substantially increases drive safety.Research proves, the frictional force that green tire produces can reduce automobile on wet and slippery or ice-patch surface 15% braking distance, make the winter driving performance of automobile improve 10%-15%.This has great meaning to minimizing casualty ratio of accidents and loss of life and personal injury.
The advantages such as green tire has braking safe, good springiness, rolling resistance is little, oil consumption is low, heat-dissipating is low, wear-resisting, puncture, supporting capacity large, ride comfort.With conventional tire ratio, environmental protection, energy-conservation, many-sided advantage such as novel process, novel material are shown especially.European Union's labeling acts passed through of making laws formally is implemented, detailed requirement is proposed to the environmental protection (fuel-economizing) of tire, security (dry, wet and slippery performance) and low noise, and other developed economies also proposes similar technical requirements, this creates considerable influence to the Tire production industry of China, that to challenge also be opportunity, corresponding enterprise is all going into overdrive to introduce and use novel material, newly formula to produce the green tire of meeting the need of market, but also runs into considerable difficulty in production implementation process:
1, complete green tire formula is the white carbon black+coupling agent of solution polymerized butylbenzene+high dispersive, and implementation cost is higher.
2, green tire is produced because of the white carbon black about 80 parts using high structure a large amount of in formula, and conventional tyre only about 10 ~ 20 parts, so technique execution and difficulty of processing are very large in tire production process, product homogeneity and poor stability.
3, existing domestic tire enterprise will reach the higher level that labeling acts specifies, as two B level tire (rolling resistance and anti-slippery all reach B level) is still difficult to.

embodiment 3
The tyre performance of above-mentioned two embodiments and DMA test result contrast as follows:
Above-mentioned two embodiments, difference is, the tire formulation of embodiment 1 not containing green tire functional master batch, for convenience of distinguishing, in simultaneous test, is labeled as 1#(blank in filling a prescription by embodiment 1), the tire formulation of embodiment 2 is labeled as 2# experiment.
Physical performance data in the green tire of car half:
Physical and mechanical properties in table, 1# and 2# is basically identical.
DMA test result is as follows:
Dynamic mechanical analysis DM A (D yn a m i c M echani ca lA n a l y s is) belongs to the one of dynamic thermomechanometry technology, be under programed temperature, measure the dynamic modulus of goods and materials under vibrational loading or the technology of mechanical loss and temperature relation.DM A measures the various transformations of macromolecular material, a kind of easy method of the thermotolerance of evaluating material, winter hardiness, consistency, damping damping effect and process industrial art performance etc., and provides information for studying high molecular aggregated structure.Due to high molecular glass transition, crystallization, orientation, be cross-linked, the structural changes such as to be separated is all closely related with the change of molecular motion state, and the change of molecular motion can be sensitive on dynamic properties reflection, therefore, dynamic mechanical analysis is a kind of effective means of research macromolecular structure change-molecular motion-performance.
Shown in Fig. 1-2, the E ' in figure is storage modulus, is directly proportional to the maximum flexibility that sample is stored in each cycle, the elastic component in reflection material viscoelasticity, the rigidity of exosyndrome material; E " is out-of-phase modulus, is directly proportional to the energy that sample consumes in the form of heat in each cycle, the viscosity component in reflection material viscoelasticity, the damping of exosyndrome material.The damping of material also claims loss modulus (D a m p i n g o f m a te r i a l s) to represent with tan δ, equals the out-of-phase modulus E of material " with the ratio of storage modulus E '.
In Fig. 1 and Fig. 2, from left number, Article 1 dotted line is E ' and the curve of temperature relation.
Article 2 dotted line is E " with the curve of temperature relation.
Article 3 solid line is the curve of tan δ and temperature relation.
From test data analysis, 2# with 1# compares, higher at the tan δ of-20 DEG C ~ 10 DEG C, shows that it is better wet skidding performance; Lower at the tan δ of 40 DEG C ~ 60 DEG C, show that its rolling resistance is lower.Abroad the general point according to 0 DEG C and 50 DEG C judges, therefore 2# formula better.
Following table is the embodiment of the present invention 1 and the contrast of embodiment 2 DMA test result:
Propose various policy and approaches aspect with exhibition trend and Chinese and foreign every country to tire environmental protection from tire, half green tire formula of the present invention has very large development prospect.
