Abstract
The invention relates to the technical field of rubber production and specifically relates to a pneumatic rubber tire. The pneumatic rubber tire is characterized by being prepared from the following raw materials in parts by weight: 20-30 parts of butadiene styrene rubber, 20-30 parts of natural rubber, 4-5 parts of zinc oxide, 10-12 parts of carbon black, 4-5 parts of silicon dioxide, 2-3 parts of isoprene, 1-3 parts of cross-linking agent, 2-3 parts of sulfur, 3-5 parts of stearic acid and 1-2 parts of anti-aging agent. The Tg of the isoprene copolymer elastomer of the pneumatic rubber tire is at least 30 DEG C lower than the Tg of other elastomers based on diene. The cross-linking agent is divinyl benzene or stannic chloride.
Description
Technical field
The present invention relates to technical field of rubber production, be specifically related to a kind of aerated rubber tyre.
Background technology
As the doughnut of automobile important component part, be that automobile bears gravity, transmitting tractive power, damping force, steering force and bears the vitals of road surface reaction, its quality, is directly involved in personal safety as well as the property safety.At present in Scrap tire, the both sides of most tire are almost intact, are exactly because tire tread wear is serious, in order to traffic safety, and abandon using, fallen like this by a large amount of expense.
Expect that very much tire has good resistance to wet skidding performance, low-rolling-resistance and good wear resistance characteristics.To there is the rubber of high resilience for the manufacture of tire tread rubber glue compound traditionally.On the other hand, in order to increase the resistance to wet skidding performance of tire, usually the rubber standing large power loss is used for the tyre surface of tire.In order to balance these two kinds character inconsistent in elasticity, usually the synthesis of each Class Type and the mixture of natural rubber are used for tire tread.
Summary of the invention
The present invention, in order to overcome the shortcoming of prior art, provides a kind of aerated rubber tyre.
Technical scheme of the present invention is: a kind of aerated rubber tyre, is prepared from by the raw material of following parts by weight: styrene-butadiene rubber(SBR) 20-30 part, natural rubber 20-30 part, zinc oxide 4-5 part, carbon black 10-12 part, silicon-dioxide 4-5 part, isoprene 2-3 part, linking agent 1-3 part, sulphur 2-3 part, stearic acid 3-5 part, anti-aging agent 1-2 part.
Linking agent of the present invention can make linking agent for Vinylstyrene or tin tetrachloride.
Styrene-butadiene rubber(SBR) (SBR), also known as polystyrenebutadienes multipolymer.Its physical mechanism performance, the use properties of processing characteristics and goods is close to natural rubber, and some performance as wear-resisting, heat-resisting, ageing-resistant and vulcanization rate is more excellent compared with natural rubber, can be used with natural rubber and various synthetic rubber.
Styrene-butadiene rubber(SBR) high temperature polymerization and interpolation ether, tertiary amine, phosphite, sulfide or tensio-active agent are as measures such as irregular agents.The molecular weight distribution of solution polymerization random styrene-butadiene rubber is narrower than SBR of emulsion polymerization, the degree of branching is also low, in order to alleviate the cold flow tendency of rubber, Vinylstyrene need be added in polymerization process or linking agent made by tin tetrachloride, making to produce between polymer molecule a small amount of crosslinked.Can also, by multipolymer blending different for molecular weight, molecular weight distribution be widened.Top formula-Isosorbide-5-Nitrae the content of isomer of solution polymerization random styrene-butadiene rubber is 35%-40%, wear-resisting, to disturb the Performance Ratio SBR of emulsion polymerization such as song, resilience, heat-dissipating good, and it is little to extrude post shrinkage.Exploring the contents of ethylene on adjustment macromolecular chain in the world, solution method styrene-butadiene rubber(SBR) was both being had good wearability, has again satisfied sliding resistance, to be applicable to high speed tire.
Natural rubber: our said natural rubber usually, refers to the natural rubber latex gathered from Para rubber tree, the elasticity decorating film made through the manufacturing procedure such as supersolidification, drying.The natural high moleculer eompound of natural rubber to be a kind of with polyisoprene be main component, molecular formula is (C
5h
8) n, its rubber hydrocarbon (polyisoprene) content, more than 90%, also grades containing a small amount of protein, lipid acid, sugar and ash.The physical property of natural rubber, has higher elasticity at normal temperatures, is slightly with plasticity, have extraordinary physical strength, hysteresis loss is little, and when being repeatedly out of shape, heat-dissipating is low, therefore its resistance to immunity in the wrong is also fine, and because be non-polar rubber, so electric edge performance is fine.
Vinylstyrene: ethene and benzene are when ethylbenzene is produced in alkylation, and obtain mixing diethylbenzene as by product, three kinds of isomer boiling points of this diethylbenzene are close, are difficult to be separated.So, usually to mix diethylbenzene raw material, through dehydrogenation produce neighbour, p-divinyl benzene.Vinylstyrene has two ethyl alkene, can generate the insoluble polymer of three-dimensional structure during copolymerization.Therefore be a kind of very useful linking agent.
Beneficial effect: a kind of aerated rubber tyre excellent property of the present invention, ageing-resistant performance is good, weight-carrying ability is high, processing characteristics is better, cost is low.
