Description
The application is entitled " a kind of low-heat-generation high abrasion-resistance rubber composition and its manufacture method ", Application No.
" 201410033355.0 ", the applying date are the divisional application of the Chinese patent application in " on January 23rd, 2014 ".
Technical field
The present invention relates to rubber materials, more particularly to tire manufacturing art.
Background technology
Automobile use will consume mass energy simultaneously and discharge substantial amounts of carbon dioxide, and the dynamic lag of reduction sizing material loses
People are enjoyed to pay close attention to always so as to reduce rolling resistance, reduce fuel consumption, reduction carbon emission.The method relevant with reduction rolling resistance
Laws ＆ Regulations are also accordingly put into effect, such as the labeling acts in Europe, the SmartWay certifications in the U.S., require reduction tire drag, its
It is middle reduction tread rubber dynamic lag loss and heat be reduce tire drag be most directly also maximally effective means it
One.The effective means that the loss of reduction sizing material dynamic lag causes tire drag and heat to decline at present is largely to use hard charcoal
It is black come alternative carbon black, but by the scattered of white carbon and and bad the brought negative effect of combination of polymer be exactly wear-resisting
The reduction of property, thus there are many researchers to do a lot of work in this respect.
Dispersant is made by a kind of modified silicon oil such as patent (application number 97191118.5) proposition and improves white carbon dispersiveness,
Improve heat and anti-wear performance, reduction Mooney viscosity.But it on the one hand may cause part silicone oil first in this way and carbon black knot
Close, reduce the possibility that rubber is combined with carbon black, it is impossible to give full play to the anti-wear performance of carbon black, on the other hand in the patent both
Add modified silicon oil and used coupling agent again, cost can be caused to increase, and modified silicon oil is not readily available, traditional rubber
Processing enterprise's especially tire plant is not easy tissue production.For another example patent (application number 201010119205.3) proposes mixed by tradition
Refine equipment using two step compounding process improvement white carbon to disperse, add carbon black when wherein second step is kneaded also is mixed into rubber simultaneously
General auxiliary agent such as age resistor, activating agent etc., some lower-molecular substances can be adsorbed onto carbon blacksurface, reduce carbon black and rubber it
Between effect, can cause carbon black to wearability contribute reduce.
The present invention utilizes the general raw material of current rubber, on the basis of general mixing facilities, using new formula and new technology
Not only improved white carbon to be combined with rubber and scattered and improve carbon black and is combined with rubber, so that reaching reduces rolling resistance and raising is resistance to
The purpose of mill property.
The content of the invention
For problem of the prior art, it is an object of the invention to provide a kind of rubber composition and preparation technology, using this
Said composition prepared by technique can be used for Tire production particularly low rolling resistance tyre and manufacture, and reduce heat, and reduction is rolled
Resistance improves wearability simultaneously.
The present invention is implemented based on following possible principle：
It is well known that can substantially reduce sizing material dynamic lag by application white carbon and silane coupler loses i.e. tan δ
Value, generally use 50-80 DEG C of sizing material, and the tan δ values under the conditions of 1-100Hz characterize tire drag, tire rolling when tan δ are low
Resistance is small, but widely applies white carbon to decline tire wear performance, Life of Tyre is influenceed, especially in truck tyre
In, thus it is general in truck tyre sizing material to use carbon black simultaneously using white carbon, to ensure wear hardness.Carbon black and rubber
With reference to better reinforcing property it is better, the present invention in addition to making larger improvement on formula, calendering process also makees larger improvement.Pass
Carbon black, age resistor, activating agent are all added together in system calendering process, and carbon blacksurface can adsorb these lower-molecular substances, reduce charcoal
Black and rubber combination, reduces reinforcing effect, thus reduces wearability.And the formula and preparation technology of the present invention are used, rubber
Glue can knead with carbon black, white carbon/coupling agent respectively in advance and form rubber master batch, add the low-molecular materials such as age resistor, activating agent
During matter, wearability can be improved, and heat can decline.White carbon and carbon black rubber master batch mixing when, it is microcosmic on make the spacing of carbon black particle
Increased from a distance between hard charcoal black track producing particle, reduce aggregation, make the reduction of tan δ values, so as to reduce tire drag and wheel viviparity
Heat.
