Described carbon black is carbon black N330 or carbon black N220.
Described anti-aging agent comprises the B type microcrystalline wax of the anti-aging agent RD of 1-90%, the antioxidant 4020 of 1-90%, the anti-aging agent 3100 of 1-90% and 20-60%.
Promotor is made up of the altax of 10-90% and the accelerant CZ of 10-90%.
Anti-agent of reverting is PK900.
Described tackiness agent comprises rosin and/or petroleum resin.Petroleum resin are C5 petroleum resin and/or C9 petroleum resin.
The calendering process of above-mentioned a kind of solution polymerized butylbenzene tread rubber, adopts three-stage mixing technique:
First paragraph: by solution polymerized butadiene styrene rubber and natural rubber, with tyre surface rubber powder, stearic acid, aromatic hydrocarbon oil, anti-aging agent, Stockholm tar, part white carbon black and carbon black, feeding Banbury mixer, mixingly obtains one section of master batch;
Second segment: one section of master batch and residue white carbon black and carbon black, zinc oxide are carried out mixing, obtains two sections of master batchs;
3rd section: two sections of master batchs and sulfur flour, anti-reductive agent and promotor are carried out mixingly obtain finished composition.
First paragraph is specially: solution polymerized butadiene styrene rubber and natural rubber are dried to temperature 30 DEG C to 40 DEG C at hot room, be ground into blob of viscose, with tyre surface rubber powder, stearic acid, aromatic hydrocarbon oil, anti-aging agent, Stockholm tar, part white carbon black and carbon black, feeding Banbury mixer, melting temperature 100-160 degree, pressure 180 Bar, rotor speed 50rpm, mixing time obtains one section of master batch for 20 seconds-2 minutes.
Second segment is specially: undertaken mixing by one section of master batch and residue white carbon black and carbon black, zinc oxide, melting temperature 100-150 degree, pressure 180 Bar, rotor speed 50rpm, mixing time obtains two sections of master batchs for 30 seconds-10 minutes.
3rd section is specially: undertaken mixing by two sections of master batchs and sulfur flour, anti-reductive agent and promotor, melting temperature 95-105 degree, pressure 165 Bar, rotor speed 20rpm, mixing time obtains finished composition in 20 seconds-5 minutes.
Beneficial effect of the present invention is: Butadiene-Styrene Rubber is divinyl, vinylbenzene is the multipolymer that monomer is obtained by solution polymerization.Have wear-resisting, resistance toly to subdue, low temperature resistant, heat-dissipating is low, rebound resilience is good, shrinkability lowly extrudes dimensional stabilizing, mixingly not easily produce gel, and the advantage such as vulcanization rate is fast.There is excellent wet skid, rolling resistance is little, heat-dissipating is low, is applicable to radial-ply tyre tyre surface.Solution polymerized butadiene styrene rubber has had the good and natural gum of newborn poly-butadiene-styrene rubber anti-slippery and the low over-all properties of cis-butadiene cement rolling resistance concurrently, has adapted to the requirement of tire environmental protection.Compared with employing Butadiene-Styrene Rubber gathers butadiene-styrene rubber with breast: tire drag reduces about 30%, anti-slippery improves about 3%, and wear resistance improves about 11%, and fuel consumption reduces 5%-6%.
Tyre surface rubber powder refers to the rubber powder obtained through physical pulverization to certain fineness with junked tire tyre surface.Mix in sizing material a certain amount of tyre surface rubber powder can improve sizing material mobility calendering, extruder rate is fast, work in-process macroscopic irregularity is few, simultaneously to the fatigue strength of sizing material, resistance toly to subdue, freedom from cracking, cracking resistance mouth increase contribution.Meanwhile, adding rubber powder can corresponding minimizing material cost.
White carbon black is compared with carbon black, and surface-area is higher, and particle is thinner, surperficial high polarity, uses that white carbon black can improve the stress at definite elongation of sizing material, colored phenomenon is collapsed in tear strength, minimizing, improves anti-flexing fatigue performance, reduces heat-dissipating.The wear resisting property of carbon black N330 or carbon black N220 is good simultaneously, coordinates, can reduce the rolling resistance of tire further with white carbon black, improves wear resistance and the tear resistance of tyre surface.Because car tire travel speed is high, for improving its stability, suitably improving the hardness of tyre surface, thus suitably have adjusted the consumption of carbon black and Sulfur.
Altax vulcanization rate is medium, sulfuration flatness is good, is applicable to most of conventional rubber, pollution-free in light sizing material, colour-fast.Accelerant CZ incipient scorch peace property is good, vulcanization rate fast, cross-linked rubber modulus is high, applied widely, is the highest active sulphenamide accelerators in EPDM.Altax and accelerant CZ use, have the advantages that inductive phase is long and vulcanization rate is fast, inductive phase is long, can fully flow when ensureing rubber vulcanization in die cavity, simultaneously at plateau cure temperature so that vulcanization reaction can be completed fast, promote conglutination reaction.
Cause in radial use procedure, producing aging principal element to have: thermo-oxidative ageing, ozone ageing, fatigue aging and photooxidation resistance.Present invention uses 3 kinds of chemical antiagers and a kind of physical antioxidant: 6PPD also known as antioxidant 4020, there is fabulous dynamic protection ozone ability, subdue even if anti-at low concentrations, ozone resistance is excellent.TMQ, also known as anti-aging agent RD, is conventional high-efficiency anti-oxidant, has long-acting restraining effect to high temperature oxidation and metal passivation.DTPD is also known as anti-aging agent 3100, and molecular weight is large, travelling speed is comparatively slow, and the protective effect time is long, with 4020 and use, not enough to make up later stage protective effect, while anti-metal toxicity ratio 4020 good, there is no the defect that tire appearance such as anti-aging agent such as use 4020 grade reddens.Physical antioxidant selects B type microcrystalline wax, and Microcrystalline Wax fusing point is high, and travelling speed is slow, and crystallization is little and even, and cere is combined with rubber firmly, flexibility good, film forming rear protecting excellent property.Effective to the protection of static ozone-induced cracking.With chemical antiozonidate with the use of there being synergy, usefulness improves, and improves resistance to daylight and ozone ageing performance.Ensure that sizing material can fully flow in tire die cavity simultaneously, resinifying reaction and sulfuration are synchronously carried out, namely produces covulcanization, form desirable interconnecting network structure.
PK900 is selected in anti-agent of reverting, and inserts new thermally-stabilised C-C cross-link bond to reduce the compound physical loss of energy caused by reversion at the Sulfur cross-link bond place of reverting.No matter be over cure, reverting of producing of high temperature vulcanized or applied at elevated temperature all can form new cross-link bond.PK900 did not react in the sulfuration starting stage, did not thus affect incipient scorch and curing time.
A kind of solution polymerized butylbenzene tread rubber of the present invention has higher hardness, preferably wear resistance, traction property, lower rolling resistance, has the advantage such as wear-resisting, ageing-resistant, resistance to puncture, anti-dry wet and slippery, lower hysteresis loss.Calendering process divides 3 sections to carry out, and efficiency is high, and carbon black and other small powders are uniformly dispersed, and the quality product produced is high, and rolling resistance is little.
