Described carbon black is carbon black N330 or carbon black N220.
Described anti-aging agent comprises the anti-aging agent RD of 1-90%, the antioxidant 4020 of 1-90%, the anti-aging agent 3100 of 1-90% and the Type B Microcrystalline Wax of 20-60%.
Promotor is comprised of the altax of 10-90% and the accelerant CZ of 10-90%.
The 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, send into Banbury mixer, mixingly obtain one section master batch;
Second segment: one section master batch and residue white carbon black and carbon black, zinc oxide are carried out mixing, obtain two sections master batchs;
The 3rd section: two sections master batchs and sulfur flour, anti-reductive agent and promotor are carried out to the mixing finished composition that obtains.
First paragraph is specially: solution polymerized butadiene styrene rubber and natural rubber are dried to 30 ℃ to 40 ℃ of temperature 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, send into Banbury mixer, melting temperature 100-160 degree, pressure 180 Bar, rotor speed 50rpm, mixing time obtains one section master batch in 20 seconds-2 minutes.
Second segment is specially: one section master batch and residue white carbon black and carbon black, zinc oxide are carried out mixing, melting temperature 100-150 degree, pressure 180 Bar, rotor speed 50rpm, mixing time obtains two sections master batchs in 30 seconds-10 minutes.
The 3rd section is specially: two sections master batchs and sulfur flour, anti-reductive agent and promotor are carried out mixing, 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 that divinyl, vinylbenzene are the multipolymer that monomer obtains by solution polymerization.Have wear-resistingly, anti-subdue, low temperature resistant, heat-dissipating is low, rebound resilience is good, shrinkability is low extrudes dimensional stabilizing, mixing difficult generation 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 the radial-ply tyre tyre surface.Solution polymerized butadiene styrene rubber has had newborn poly-butadiene-styrene rubber anti-slippery good and natural gum and the low over-all properties of cis-butadiene cement rolling resistance concurrently, has adapted to the requirement of tire environmental protection.Adopt the poly-butadiene-styrene rubber of Butadiene-Styrene Rubber and breast to compare: tire drag reduces by 30% left and right, and anti-slippery improves 3% left and right, and wear resistance improves 11% left and right, and fuel consumption reduces 5%-6%.
The tyre surface rubber powder refers to the rubber powder obtained through physical pulverization to certain fineness with the junked tire tyre surface.Mix a certain amount of tyre surface rubber powder and can improve that mobility calendering, the extruder rate of sizing material is fast, work in-process macroscopic irregularity is few in sizing material, simultaneously to the fatigue strength of sizing material, anti-ly subdue, freedom from cracking, cut growth resistance have contribution.Simultaneously, add the 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, and colored phenomenon is collapsed in stress at definite elongation, tear strength, the minimizing of using white carbon black can improve sizing material, improves anti-flexing fatigue performance, reduces heat-dissipating.The wear resisting property of carbon black N330 or carbon black N220 is good simultaneously, with white carbon black, coordinates, and can further reduce the rolling resistance of tire, improves wear resistance and the tear resistance of tyre surface.Because car tire travel speed is high, for improving its stability, suitably improve the hardness of tyre surface, thereby suitably adjusted the consumption of carbon black and Sulfur.
The altax vulcanization rate is medium, the sulfuration flatness is good, is applicable to most of conventional rubbers, pollution-free in light sizing material, colour-fast.Accelerant CZ incipient scorch peace property is good, vulcanization rate fast, the cross-linked rubber modulus is high, applied widely, in EPDM, is the highest active sulphenamide promotor.Altax and accelerant CZ use, have the advantages that inductive phase is long and vulcanization rate is fast, and inductive phase is long, can be fully mobile in die cavity while guaranteeing rubber vulcanization, simultaneously at the plateau cure temperature can complete fast vulcanization reaction, to promote conglutination reaction.
Causing in the radial use procedure producing aging principal element has: thermo-oxidative ageing, ozone ageing, fatigue aging and photooxidation resistance.The present invention has used 3 kinds of chemical antiagers and a kind of physical antioxidant: 6PPD to claim again antioxidant 4020, has fabulous dynamic protection ozone ability, even anti-under lower concentration, subdues, ozone resistance is good.TMQ claims again anti-aging agent RD, is high-efficiency anti-oxidant commonly used, and high temperature oxidation and metal passivation are had to long-acting restraining effect.DTPD claims again anti-aging agent 3100, and molecular weight is large, travelling speed is slower, and the protective effect time is long, and with 4020 use also, to make up later stage protective effect deficiency, anti-metal toxicity is better than 4020 simultaneously, the defect of not using 4020 tire appearances such as anti-aging agent such as grade to redden.Physical antioxidant is selected the Type B Microcrystalline Wax, and the Microcrystalline Wax fusing point is high, and travelling speed is slow, and crystallization is little, and and even, cere is combined with rubber firmly, and subduing property is good, film forming rear protecting excellent property.Protection to static ozone-induced cracking is effective.Be used in conjunction with synergy with chemical antiozonidate, usefulness improves, and has improved anti-daylight and ozone ageing performance.Guarantee that sizing material can be fully mobile in the tire die cavity simultaneously, make the resinifying reaction synchronize and carry out with sulfuration, produce covulcanization, form desirable internet structure.
PK900 is selected in the anti-agent of reverting, and inserts new thermally-stabilised C-C cross-link bond at the Sulfur cross-link bond place of reverting to reduce the sizing material physical property loss of energy caused by reversion.No matter be over cure, high temperature vulcanized or applied at elevated temperature produces reverts and all can form new cross-link bond.PK900 did not react in the sulfuration starting stage, thereby did not affect incipient scorch and curing time.
A kind of solution polymerized butylbenzene tread rubber of the present invention has higher hardness, wear resistance, traction property, lower rolling resistance preferably, has wear-resisting, ageing-resistant, anti-puncture, anti-dry wet and slippery, the lower advantages such as 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 of producing is high, and rolling resistance is little.
