Abstract
The invention discloses a rubber composition for auto tyres and belongs to the technical field of auto tyres. According to the invention, the rubber composition for auto tyres is mainly compounded of butadiene styrene rubber, styrene-isoprene-butadiene rubber and butadiene rubber in the presence of linseed oil, aromatic modified terpene resin, light calcium carbonate, silica, zinc stearate, dibutyl ester, magnesium oxide, methyl 2,2-dithienylglycolate and sodium pyrosulfite; and the heat generation property of the rubber composition can b reduced effectively.
Description
Technical field
The present invention relates to doughnut technical field, particularly relate to a kind of doughnut rubber combination.
Background technology
Tire is one of vitals of automobile, and it directly contacts with road surface, and impact suffered when automotive suspension relaxes running car jointly, ensures that automobile has good driving comfort and ride performance; Ensure that there is good tack on wheel and road surface, improve the traction property of automobile, braking and the property passed through; Subject the weight of automobile, tire on automobile the vital role that rises more and more be subject to people's attention, cause the requirement of people to its various aspects of performance also more and more higher, and the low heating property improving tyre element rubber combination is one of them.
Summary of the invention
The invention provides a kind of doughnut rubber combination, this doughnut rubber combination has lower heat generation.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
It is made up of the component of following weight part:

In technique scheme, technical scheme is more specifically: 35 parts, styrene-butadiene rubber(SBR), styrene isoprene butadiene rubber (SIBR) 20 parts, cis-1,4-polybutadiene rubber 20 parts, linseed oil 22 parts, aromatic modified terpine resin 26 parts, light calcium carbonate 10 parts, silicon-dioxide 6 parts, Zinic stearas 2 parts, dibutylester 1 part, 3 parts, magnesium oxide, 2,2-dithienyl methyl glycolate 4 parts and Sodium Pyrosulfite 3 parts.
Further, 46 parts, styrene-butadiene rubber(SBR), styrene isoprene butadiene rubber (SIBR) 30 parts, cis-1,4-polybutadiene rubber 30 parts, linseed oil 18 parts, aromatic modified terpine resin 20 parts, light calcium carbonate 8 parts, silicon-dioxide 5 parts, Zinic stearas 3 parts, dibutylester 3 parts, 1 part, magnesium oxide, 2,2-dithienyl methyl glycolate 3 parts and Sodium Pyrosulfite 1 part.
Further, 40 parts, styrene-butadiene rubber(SBR), styrene isoprene butadiene rubber (SIBR) 25 parts, cis-1,4-polybutadiene rubber 26 parts, linseed oil 20 parts, aromatic modified terpine resin 24 parts, light calcium carbonate 12 parts, silicon-dioxide 8 parts, Zinic stearas 4 parts, dibutylester 5 parts, 2 parts, magnesium oxide, 2,2-dithienyl methyl glycolate 4 parts and Sodium Pyrosulfite 5 parts.
Owing to adopting technique scheme, the beneficial effect that the present invention obtains is:
The present invention mainly selects styrene-butadiene rubber(SBR), styrene isoprene butadiene rubber (SIBR), and cis-1,4-polybutadiene rubber three kinds of rubber are composite, be equipped with linseed oil again, aromatic modified terpine resin, light calcium carbonate, silicon-dioxide, Zinic stearas, dibutylester, magnesium oxide, 2,2-dithienyl methyl glycolate and Sodium Pyrosulfite make doughnut rubber combination together, can effectively reduce its heat generation.
