Performance, all contain small molecular organic compounds in sizing material used, filler, compounding ingredient and vulcanizing agent, while in vulcanization reaction mistake
VOC can be produced in journey again.Rubber is produced irksome smell, danger is caused to environment, human body
Evil.The smell of reduction rubber needs to conduct a research from many aspects such as raw material, vulcanizing systems.As social environment consciousness is carried
Rubber oder levels are required also stricter by height.
Therefore, it is necessary to propose effective technical scheme, solve the above problems.
The content of the invention
There is provided a kind of low smell tread rubber composition for above-mentioned the deficiencies in the prior art by the present invention.The building rubber compound
Thing odor properties grade is high.
The technical scheme that the present invention solves above-mentioned technical problem is as follows：
A kind of low smell tread rubber composition, the composition includes following components：1-60 parts of natural rubbers, 1~50
Part styrene and butadiene copolymer material, 1~80 part of neodymium series cis-polybutadiene rubber, 10~80 parts of reinforced fillings, 1~
30 portions of petroleum oil, 1-2 portions of sulphur, 2-2.5 portions of sulfenamide type accelerators；The neodymium series cis-polybutadiene rubber is by neodymium series
Catalyst is synthesized, and Mooney viscosity ML1+4 (100 DEG C) is within 39~49, and Tg points are between -60~-100 DEG C, wherein suitable
The content of formula butadiene is in more than 98wt%, and the content of trans butadiene is in below 2wt%.
Preferably, styrene-content is within 1-50% in the styrene and butadiene copolymer material, 1,2- ethene
Base content is within 0-80%, and Tg points are between -10 DEG C~-90 DEG C.
Preferably, the sulphur is oil-filled Cosan, and sulfur content is more than 98%.
Beneficial effect：Heretofore described accelerator is sulfenamide type accelerators, is closed by cyclohexylamine and benzothiazole
Into, it is acid to promote base, and activation base is alkalescence, thus for soda acid self and use the accelerator of type, activated group in vulcanization instead
After should terminating, and with promoting group to be combined, will not exist in sizing material with free monomer state.Using neodymium series butadiene rubber and time
Sulfonamides accelerator can effectively reduce sizing material smell.Reason is that in product sulfidation, the small molecule volatile of generation has
Machine compound is few, so as to reduce the volatile small molecule of rubber, the oder levels of sizing material is also improved.
Embodiment
The present invention relates to a kind of low smell tread rubber composition, the composition includes following components：1-60 parts natural
Rubber, 1~50 part of styrene and butadiene copolymer, 1~80 part of neodymium series cis-polybutadiene rubber, 10~80 parts of reinforcement are filled out
Material, 1~30 portion of petroleum oil, 1-2 portions of sulphur, 2-2.5 portions of sulfenamide type accelerators；The neodymium series cis-polybutadiene rubber

The content of wherein cis butadiene is in more than 98wt%, and the content of trans butadiene is in below 2wt%.
Heretofore described accelerator is sulfenamide type accelerators, is to be synthesized by cyclohexylamine with benzothiazole, is promoted
Base is acid, and activation base is alkalescence, thus for soda acid self and with the accelerator of type, activated group after vulcanization reaction terminates,
Again with promoting group to be combined, will not exist in sizing material with free monomer state.
It is weight to reduction rubber smell to be considered as using neodymium series butadiene rubber and sulfenamide type accelerators in the present invention
Want.
As one embodiment of the present of invention, wherein,
The natural rubber is the copolymer along 1,4- polyisoprene；
The styrene is with styrene-content in butadiene copolymer material within 1-50%, and 1,2- contents of ethylene exists
Within 0-80%, Tg points are between -10 DEG C~-90 DEG C；
The reinforced filling includes all types carbon black, can directly or indirectly with rubber molecule generation physics and chemistry
With reference to；Carbon black iodine absorption number is in more than 120g/kg, and DBP absorption values are in 60-120cm3/ 100g, N2 adsorption specific surface area is in 119m2/g
More than；
The sulphur is oil-filled Cosan, sulfur content ＞ 98%；
The petroleum oil is environment protection oil, kinematic viscosity (100 DEG C)/mm2·s-1:10~30, flash-point/DEG C：271, pour point/
℃：33, index of refraction (20 DEG C)：1~2, polycyclic aromatic hydrocarbon mass fraction：0~1, carbon atom proportion/%：CA：0~50%, CN：
0~50%, CP：0~50%.
The mixing of rubber composition can use method known to rubber compounding art technical staff to complete.For example in usual feelings
Under condition, each component is kneaded at least two stages, i.e. at least one unproductive mix stage, with latter production
Property mix stage.Rubber is kneaded with fluoropolymer resin in one or more unproductive mix stages.
Example：
The rubber composition of defined composition in such as table 1 is prepared in BR Banbury banburies, preparation process takes four
Individual separated charging mix stage, i.e. three unproductive mix stages and a productivity mix stage.Three unproductive
