Description

For the half hot melt tread rubber composition of racing car with drift tire
Technical field
The present invention relates to the tread rubber composition of a kind of racing car drift tire of field of rubber technology, particularly this racing-car tyre is half hot melt tire.
Background technology
Tire is one of most important parts of automobile, does not have tire automobile just inactive.In motor sport, tire has influence on the games results of match hand especially.Because of various reasons, as wear resistance, noise, rolling resistance, the dry wet braking of tire, the tire that existing vehicle is equipped with is not classic product many times.
Summary of the invention
For pursuing the user driving and require very-high performance, the tire of existing vehicle outfit can not meet their needs.The half hot melt tire that they need more general tire more mobilisation, the feature of this tire is: tyre surface is softer, only needs to travel very short distance and just can reach about 90 DEG C, and produce very high viscosity, produce great adherence properties power.
The technical solution used in the present invention is: for half hot melt tread rubber composition of racing car drift tire, according to parts by weight, it is made up of following material: base rubber 137.50 parts, high-dispersion white carbon black 70 ~ 90 parts, carbon black 10 ~ 30 parts, silane coupling agent 5 ~ 7 parts, promoting agent 4 ~ 7 parts, N(1, 3-dimethylbutyl)-N '-diphenyl-para-phenylene diamine 1.50 parts, 2, 2, 4-trimethylammonium-1, 2-dihydro Kui Lin polymer 1.00 parts, Microcrystalline Wax 1.50 parts, promotor 4.50 parts, 1.50 parts, sulphur, scorch retarder 0 ~ 0.40 part, also comprise heat-fusible materials 20 ~ 60 parts.
Described heat-fusible materials comprises multiple different material, and the melting temperature (Tm) of this multiple heat-fusible materials is different.
Described heat-fusible materials is α methyl-styrene indene resin, anti tear resin, pure monomer resin and pure monomer resin.
Described α methyl-styrene indene resin is 10 ~ 20 parts, and anti tear resin is 10 ~ 20 parts, and pure monomer resin is 0 ~ 10 part, and C5 petroleum resin are 0 ~ 10 part.
Described base rubber is α methyl-styrene indene resin.
Described promotor is stearic acid, and described promoting agent is zinc oxide.
Polymkeric substance adopts the molten poly-styrene-butadiene rubber(SBR) of high styrenic percentage, high-vinyl-content, the dry wet braking ability of main consideration.Its ultimate principle is that the wet-sliding resistant performance of sizing material is main relevant to the Tan δ 0 DEG C in the Dynamic Viscoelastic performance of sizing material, Tan δ@0 DEG C is larger, anti-slippery is better, high styrenic percentage, high-vinyl-content can make the Tg of sizing material rise, DMA curve is moved to right, result is that the value of Tan δ@0 DEG C rises, and wet-sliding resistant performance improves.Face, the main line braking ability of sizing material is main relevant to the Tan δ 23 DEG C in the Dynamic Viscoelastic performance of sizing material, Tan δ@23 DEG C is larger, dry ground braking ability is better, high styrenic percentage, high-vinyl-content can make the Tg of sizing material rise, DMA curve is moved to right, result is that the value of Tan δ@23 DEG C rises, and dry ground braking ability improves.
Reinforcement system adopts the silicon tire technology of white carbon black+silane coupling agent, balances rolling resistance and dry wet braking ability.Its ultimate principle is that the oxyethyl group of silane coupling agent when mixing, chemical reaction occurs with the hydroxyl on white carbon black surface, the sulphur of silane coupling agent and rubber macromolecule chain generation vulcanization reaction when sulfuration, white carbon black is connected by chemical bond with rubber macromolecule chain, and carbon black is normally connected by Intermolecular Forces with the combination of rubber macromolecule chain, Intermolecular Forces is more weak and the bond energy of chemical bond is higher, sizing material under external force, Intermolecular Forces is opened, filler and rubber are subjected to displacement the larger hysteresis loss of generation and produce heat, the bond energy of chemical bond is higher not easily to be interrupted, hysteresis loss is little, rolling resistance is low.The adhesivity that the wetting ability of white carbon black determines it and ground is good, and dry wet braking ability is good.
The heat-fusible materials of multiple different softening point is non-reaction material, and minimum a kind of melting temperature (Tm) is 85 DEG C, and the highest one is 140 DEG C, can melt gradually, produce very high adhesivity with road surface, produce intrepid adherence properties along with the rising of tyre temperature.(if the softening temperature of α methyl-styrene indene resin is at about 85 DEG C, the softening temperature of pure monomer resin is at about 140 DEG C), the earth-catching property under what softening temperature was low improve wet road surface, what softening temperature was high improves dry ground earth-catching property.
Embodiment
Tire of the present invention is half hot melt tire, not only can use as racing-car tyre, also can be used for drive routine to provide preferably comfortableness.It is the mobility tire that can legally set out on a journey.
