Description
Technical field
The present invention relates to the rubber technology field, specifically a kind of sedan-chair card rubber composition for tyre with low-rolling-resistance and anti-slippery.
Background technology
As everyone knows, tire mainly is made up of parts such as tyre surface, sidewall, cord, Steel Traveler.And tyre surface has very important effect to the quality of tire.Rolling resistance, anti-slippery and wear resistance are called as three big rideabilities of tire, influence each other between them, mutual restriction.For reducing tire drag, require the hysteresis loss of tread rubber little low with second-order transition temperature.The height of second-order transition temperature also can reflect the quality and the tire anti-slippery in the winter time of wear hardness.Be grabbing property of raising, require the hysteresis loss of tread rubber big, this rolling resistance to tire has very big influence.Therefore, the rolling resistance of tire, anti-slippery reach particularly key of balance between the two.External many experts research shows, the rolling resistance of tire is that the quality by the dynamic deformation of tyre stock and tire itself causes.Under lesser temps (20～20 ℃), have higher dissipation factor (tan δ), and (50-70 ℃) has the tread rubber of lower tan δ under higher temperature, has low-rolling-resistance and anti-slippery simultaneously, thereby reaches environment protection requirement.
Summary of the invention
The object of the invention is exactly in order to overcome the deficiency of above-mentioned prior art; A kind of sedan-chair card tire tread rubber combination is provided; Add a kind of nontoxic, force of cohesion is big, bonding force is strong, be prone to the dispersive resin, reduces tire drag and anti-slippery gets effect thereby reach.
The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of sedan-chair card tire tread rubber combination,
Rubber components with 100 weight parts is a benchmark, also comprises
The carbon black of 30～100 weight parts,
The WHITE CARBON BLACK of 10～30 weight parts,
The terpine resin of 4～10 weight parts,
1.5 the sulphur of～4.0 weight parts,
1.7 the sulfenamide vulcanization accelerator of～3.5 weight parts;
Wherein said rubber components is 20～45 weight part polybutadiene rubbers, 45～80 weight part solution polymerized butadiene styrene rubbers.
The invention has the beneficial effects as follows, in tire tread prescription, add a kind of nontoxic, force of cohesion is big, bonding force is strong, be prone to the dispersive new type resin, thereby reach the reduction tire drag and anti-slippery gets effect.
Embodiment
Below in conjunction with embodiment the present invention is done further description:
The present invention is used for the tire tread glue composition and contains rubber components, carbon black, new type resin, insoluble sulfur and vulcanization accelerator etc.
Rubber components comprises polybutadiene rubber (BR) and solution polymerized butadiene styrene rubber (S-SBR).
The consumption of the polybutadiene rubber BR that relates among the present invention is preferably and is not less than 20 weight parts, further is preferably and is not less than 25 weight parts, when the consumption of BR is lower than 20 weight parts, is difficult for obtaining low rolling resistance performance; In addition, the consumption of BR is preferably and is no more than 45 weight parts, further is preferably and is no more than 40 weight parts, when the consumption of BR surpasses 45 weight parts, will have a negative impact to the earth-catching property on the wet road surface of tire.
The virgin rubber Mooney viscosity value of polybutadiene rubber BR among the present invention is 35-75, be to guarantee the physical and mechanical properties of tire, should select the BR of higher Mooney point as far as possible, so the selection of Mooney point looks processing conditions and decide, and is recommended as about 60.
The content of S-SBR in the rubber components is preferably and is not less than 45 weight parts, further is preferably and is not less than 50 weight parts.When the content of S-SBR is lower than 45 weight parts, be difficult for obtaining enough grabbing property and low-rolling-resistance and wear resistant.The content of S-SBR is preferably and is no more than 80 weight parts in addition, further is preferably and is no more than 75 weight parts.When the content of S-SBR surpasses 80 weight parts, this will be unfavorable for the improvement of abrasion resistance and fuel-economizing performance.
Do not limit carbon black is special, can use those carbon blacks that have been used for tire industry.
Rubber combination with 100 weight parts is a benchmark, and sooty content is not less than 30 weight parts, is preferably and is not less than 35 weight parts.When sooty content is lower than 30 weight parts, can not obtain enough strengthening the property.In addition, sooty content is no more than 100 weight parts, is preferably to be no more than 90 weight parts.When sooty content surpassed 100 weight parts, the wear resistance of tire descended.
WHITE CARBON BLACK has the tear strength height, living heat is low and S-SBR collocation use has fabulous low-rolling-resistance and anti-slippery.
New type resin is actually phenol-modified terpine resin, and its consumption in prescription is 4～10 weight parts.Be dissolved in aromatic hydrocarbons, ketone, the esters solvent bonding force is strong, force of cohesion is big, thermotolerance is high, ageing-resistant, good, nontoxic with rubber compatibility.Be used in the rolling resistance that can reduce tire in the tyre surface formula.
The sulphur powder is not had special regulation, can use the sulphur powder that has been used for tire industry.
The usage quantity of sulphur powder, with the system that 100 weight part synthetical glues are the basis, the usage quantity of sulphur powder is no more than 4.0 weight parts, is preferably to be no more than 4.0 weight parts, when powder surpasses 4.0 weight parts, causes using the material sulfuring up of this prescription easily; Usage quantity is not less than 1.5 weight parts, is preferably to be not less than 1.7 weight parts, and when powder was lower than 1.5 weight parts, it is abundant inadequately that state of vulcanization is carried out, with the physical strength performance that has a strong impact on sizing material.
The sulfenamide type accelerators that uses among the present invention has the N-tertiary butyl-2 benzothiazole sulphenamide (accelerator NS), N-oxygen diethylene-2-benzothiazole sulfonamide (accelerant N OBS), N; N-two cyclohexyl benzothiazole sulfonamides (accelerator DZ), N; N '-dicyclohexyl-2-[4-morpholinodithio sulphenamide (accelerant CZ); Consideration is to the requirement of the friendly and the vulcanization rate of environment, preferred accelerators NS and accelerant CZ.
Be that the amount of the sulfenamide type accelerators that uses of foundational system is no more than 3.5 weight parts with 100 weight part synthetical glues in the invention, when powder surpasses 3.5 weight parts, cause the safety performance at sizing material processing initial stage to reduce easily; The minimum amount of promotor is not less than 2.0 weight parts, is preferably to be not less than 1.7 weight parts, and when accelerator level is lower than 1.7 weight parts, vulcanization rate will reduce, and influences the sulfuration efficient of finished tire.
In addition; Among the present invention except that the sulfenamide type accelerators that uses as the primary accelerator, generally also need and use a certain amount of secondary accelerator, type that curing Dibenzo thiazole (altax), diphenylguanidine (vulkacit D PG) are arranged; Consideration is to the requirement of vulcanization rate, preferred accelerators DPG.
At the rubber combination that is used for tread rubber of the present invention; Except that above-mentioned rubber components, carbon black, insoluble sulfur, vulcanization accelerator; According to circumstances need also can be suitable sneak into the various Synergist S-421 95s that are used for tire industry, for example, adhesive agent, Triple Pressed Stearic Acid and zinc oxide etc.
