Description
Technical field
The present invention relates to a kind of tire tread and preparation method thereof.
Background technology
Diphenylguanidine PG, also known as diphenylguanidine, chemical name is N, N ＇-diphenylguanidine, its fusing point >=140 DEG C, purity >=
95.0%, relative density is 1.10~1.20, irritant when being contacted with skin.Existing diphenylguanidine PG (N, N ＇-diphenylguanidine) with
Thiazole accelerator paralled system is widely used in the production of rubber, is also commonly used for white carbon filling solution polymerized butadiene styrene rubber
(SSBR) covering, makes SSBR sizing materials have remarkable physical property and dynamic property.But diphenylguanidine PG is in the vulcanization of rubber
During the aniline containing carcinogen in analyte, therefore it is using being subject to certain restrictions.
Therefore, as one of highly important accelerator of rubber industry, diphenylguanidine PG has been substituted using environment-friendly type accelerator
As trend, it is necessary to propose effective technical scheme, solve the above problems.
The content of the invention
There is provided a kind of tire tread for above-mentioned the deficiencies in the prior art by the present invention.When the tire tread can extend incipient scorch
Between, improve modulus, lifting wear hardness and reduction rolling resistance
The technical scheme that the present invention solves above-mentioned technical problem is as follows：
A kind of tire tread, the tyre surface includes：1~60 part of solution polymerized butadiene styrene rubber, 1~40 part of natural rubber, 1.5 parts of rings
Guarantor's type accelerator, 10~100 parts of high-dispersion white carbon blacks, 1~8 part of silane coupler, 10~50 parts of carbon blacks, and 1~20 part of stone
Oil system aromatic naphtha.
Preferably, the environment-friendly type accelerator is the compound of zinc dialkyl dithiophosphate and carrier.
The present invention also provides a kind of preparation method of tire tread.This method can avoid poisonous, allergy in operating process
And carcinogenic risk.
Specifically, preparation process takes three separated charging mix stages, it is respectively, two unproductive mix stages
With a productivity mix stage；Wherein, non-productive stage carries out about 2~5min mixing respectively, until rubber temperature reaches
To 160 DEG C, that is, complete；The mixing time for producing the sexual stage is the time for making rubber temperature reach 105 DEG C.
It is preferred that, the environment-friendly type accelerator adds in the production sexual stage.
Beneficial effect：Solution polymerized butadiene styrene rubber, natural rubber, high-dispersion white carbon black, silane coupler and environmental protection in the present invention
Being used in combination for type accelerator is considered as to extension time of scorch, improves modulus, lifting wear hardness and reduction rolling resistance
Power is important.
And the use for the environment-friendly type accelerator being related in the present invention can avoid in operating process poisonous, allergy and carcinogenic
Risk.
Embodiment
A kind of tire tread, the tyre surface includes：1~60 part of solution polymerized butadiene styrene rubber, 1~40 part of natural rubber, 1.5 parts of rings
Guarantor's type accelerator, 10~100 parts of high-dispersion white carbon blacks, 1~8 part of silane coupler, 10~50 parts of carbon blacks, and 1~20 part of stone
Oil system aromatic naphtha.
Wherein, the environment-friendly type accelerator is the compound of zinc dialkyl dithiophosphate and carrier.
In the solution polymerized butadiene styrene rubber, styrene 0~60%, contents of ethylene accounts for 10%~70%, Tg points for -10 DEG C
~-50 DEG C；
The natural rubber is polymer of the 1,4- along polyisoprene；
The high-dispersion white carbon black N2 adsorption specific surface area is in 120~200m2/ g, can be directly or indirectly with rubber point
Physics and chemical bond occur for son；
The silane coupler is a kind of sulfur-containing organosilicon compounds with functional group；
The carbon black iodine absorption number is in more than 100g/kg, and DBP absorption values are 90~14010-5m3/ kg, can directly or
What is connect occurs physics and chemical bond with rubber molecule；
The petroleum aromatic naphtha is environment-friendly aromatic oil, kinematic viscosity (100 DEG C)/mm2·s-1:10~100, flash-point/DEG C：
>=220,20 DEG C of refraction indexs：1.400~1.600, carbon atom proportion/%：CA：20~45%, CN：20~35%, CP：
20~45%.
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.
The rubber composition of defined composition in such as table 1 is prepared in Banbury banburies, preparation process takes three points
