Description
Technical field
The invention belongs to tire manufacturing techniques field, be specifically related to a kind of Sidewall rubber of automobile tire.
Background technology
Tire is one of vitals of automobile, and it directly contacts with road surface, and impact suffered when automotive suspension relaxes running car jointly, ensures that automobile has good driving comfort and ride performance; Ensure that there is good tack on wheel and road surface, improve the traction property of automobile, braking and the property passed through; Subject the weight of automobile, tire on automobile the vital role that rises more and more be subject to people's attention.Doughnut, in the use of automobile, is even more important, and doughnut is related to the safety performance of automobile.
Appearance along with automobile in 1895, pneumatic tyre was developed widely, and first batch of doughnut sample occurs in France for 1895, and this is the single hose tire be made up of plain weave canvas, though have sidewall rubber without decorative pattern.
Cord has been invented in the Berli Mill of Britain in 1892,1910 for the production of, this achievement, except improving tire quality, expands outside tire kind, the possibility that also to have made cover tire possess molded.Along with the raising required tire quality, cord quality is also improved, cotton cord is replaced by artificial silk, the end of the fifties artificial silk again, nylon that resistance toheat higher, polyester cord better replace by strength property, and steel wire cord is along with the development of radial, there is very strong competitive power.
Within 1904, Ma Te creates carbon black reinforced rubber, extensive is after tire adopts cord for reinforcement sidewall rubber, because before this, canvas damages also fast in tire used than tyre surface, the consumption of carbon black in sizing material increases very fast, the carbon black that the thirties uses in every 100 parts of rubbers about 20 parts only, at this moment mainly on tyre surface, adopts carbon black, carcass need not, reached more than 50 parts.Mix in tyre surface before carbon black, tire approximately only travels 6000km and has just polished, and after mixing carbon black, the actual service life of tire is significantly improved soon.Rake of wagons tire about wheeled 100,000 km, on good road surface, even can reach 200,000 km.
1913-1926, because having invented cord and carbon black tire technology, for tire industry development is laid a good foundation.The stdn of tire outer rim, manufacturing process perfect gradually, production rate improve than in the past, and the output of tire grows with each passing day.
Along with the development of automotive industry, tire technology is extension and improvement all the time, as the beginning of the twenties to the mid-1930s car tire is transitioned into extra-low pressure tire by low pressure tyre; Start tire the forties progressively to wide wheel rim transition; The end of the forties tubeless tyre appearance; The end of the fifties, low-profile tyre came out etc.The appearance of many new technologies is all no more than meridian structure tire that French Michelin company in 1948 is pioneering, this tire significantly improves due to work-ing life and use properties, particularly under steam can fuel saving, and be described as the revolution of tire industry, main several tire characteristics of the Developing of making brief of the introduction here.
Rubber, as the main raw material in tire production, affects the quality of doughnut.Rubber or rubber item, in processing, storage and use procedure, owing to being subject to the effect of various extraneous factor, and progressively lose original premium properties, to finally losing use value.Therefore to carry out improving and designing for the aging of rubber, create a kind of anti-aging, doughnut work-ing life can be extended and the higher tire of safety coefficient.
Sidewall and tire both sides; it is the maximum position of lateral deformation; sidewall rubber is thinner; in order to protect carcass from physical abuse and daylight, erosion by wind and rain; its damage type is flex crack, physical abuse, and therefore sidewall rubber should have good strength and extension property and the performance such as flex cracking resistance, resistance to atmospheric aging.
The sidewall of radial is extended large, the flexing fatigue stood is more serious than bias tyre, but it is very little by shear strain, in view of this, in order to ensure that sidewall rubber can keep good cement properties with miscellaneous part when shaping, thus requires the anti-flexural property of sidewall sizing material, heat resistanceheat resistant oxygen, ozone-resistant aging resistance are excellent, higher and the elongation of tensile strength is comparatively large, makes it strain when bearing large stress lower, and sidewall rubber also requires to be able to take radial tyre construction of being repeatedly remoulded and is heated.
Sidewall rubber material formula generally adopts natural rubber and synthetic rubber and uses, if with cis-1,4-polybutadiene rubber and the used time, doping level can not be too high, though because of the multiplex flex fatigue life that can improve sidewall rubber, but sidewall intensity and tear-resistant performance also decline thereupon, the cement properties of rubber unvulcanizate is also bad, and therefore, the doping level of cis-1,4-polybutadiene rubber is advisable with 30-50 part.
Sidewall rubber can make strengthening agent with FF fine furnace black (as medium super abrasion furnace black, high abrasion furnace black(HAF), general purpose furnace black or fast extruding furnace black), the total consumption of suitable raising carbon black, the strength and extension property of sizing material can be improved, for the ozone-resistant improving sizing material is aging and flex fatigue life, can adopt antioxidant 4010NA 4020,4010 and BLE or AW use, the total consumption of anti-aging agent can suitably improve, as used with microcrystalline wax, can play collaborative anti-aging effect, protection effect can be better.
Therefore, in view of service requirements and the performance requriements of tire sidewall sizing material, reasonably must configure various feed composition and ratio thereof, make tire have better properties, strengthen its flex fatigue life, strengthen its sidewall intensity and tear-resistant performance.

Tire obtained by the formula of the above embodiments 1, its performance perameter is as follows:
Flex crack number of times × 10
-4/ time be: 0.212;
Akron abrasion weight/cm
3;
Tensile strength: 26.4/Mpa;
Tear strength is: 93/KNm
-1;
Shore hardness: 71;
300% stress at definite elongation/Mpa:12.4.
As can be seen from above data, adopt the tire that the raw material in embodiment 1 and proportioning are produced, its flex crack is little, and wear resistance is good.
By common commercially available tire A compared with the tire of the present embodiment;
The durability experiment of finished tire is as follows:
The tire of the present embodiment, accumulative running time is 76 hours, accumulative actual service life: 4230 kilometers;
Conventional tyre, accumulative running time is 68 hours, accumulative actual service life: 3720 kilometers;
The high speed performance test experiments of finished tire is as follows:
The tire of the present embodiment, Negotiation speed be 120 kilometers per hour, accumulative running time is 14.2 hours;
Conventional tyre, Negotiation speed be 103 kilometers per hour, accumulative running time is 11.2 hours.
Sidewall rubber is greater than other position due to its distortion, the sidewall distortion of radial is larger, the warping strength cracking of sizing material, resistance to ozone ageing are then leading indicator, when formulating of recipe, cis-1,4-polybutadiene rubber, natural rubber, styrene-butadiene rubber(SBR) is selected to match, due to cis-1,4-polybutadiene rubber, to there is processing characteristics poor, and rubber has the shortcomings such as certain cold flow tendency.The oil-extended butadiene rubber occurred can make above-mentioned shortcoming obtain improvement to a certain extent.But its tearing toughness is on the low side, and anti-slippery is bad, and tackiness is not as natural rubber and styrene-butadiene rubber(SBR), and therefore, by above-mentioned several rubber phase combinations, synergy, strengthens tearing toughness, anti-slippery ability.
Terpolymer EP rubber has the performances such as ozone resistance, weather resisteant, thermotolerance and chemical-resistant stability, adds the sulfuration of insoluble sulfuy promotor vulcanization system, sidewall can be made will to have higher intensity; And the resistance to low temperature of terpolymer EP rubber is good, electrical insulation capability might as well.
