Description
Technical field
The invention discloses a kind of preparation methods of anti-skid wearable tread rubber, belong to technical field of rubber preparation.
Background technology
Tread rubber refers to outermost tyre layers and is contacted with road surface and surface is printed on a layer sizing of decorative pattern.It can make tire that there is traction
Power buffers impact when driving and waves, and prevents cutting and piercing through for cord ply.Require the wearability, resistance to tired of height
Labor performance, good ageing-resistant performance, higher tensile strength, elasticity and obdurability, and heat generation low when driving.It can use
The raw rubbers such as natural rubber, butadiene-styrene rubber, cis- isoprene rubber and butadiene rubber manufacture.A large amount of carbon blacks are commonly incorporated into sizing material, to carry
Its high physical mechanical property.Sizing material worm press can be extruded or be formed through cooling with calender calendering.Preceding method is made
Tread rubber, quality is more excellent, and production capacity is also larger.The tyre cement used in cover tire is repaired, tread rubber is also often claimed.
Rolling resistance, anti-slippery and wearability are tire " three big driving performances ", influence each other between three performances,
It restricts, the balance optimizing being difficult to realize between three, therefore has the title of tyre performance " Magic triangle ".Ideal tread rubber should have low
The comprehensive excellent performance such as rolling resistance, the wearability become reconciled of high anti-slippery.Traditional method of modifying of tread rubber is adjustment
The formula of tread rubber composite material, such as rubber raw materials and new packing that development and application are novel.Using the nanometers nothing such as white carbon
Machine filler prepares the hot spot that green tread rubber composite material is current tread rubber composite material research, but nanoscale inorganic particles
Agglomeration power is strong, the poor processability of filler gum, it is difficult to be dispersed in rubber matrix.
Car tire generally uses semi-steel wire radial tire structure, half-steel meridian tyre to refer to tyre surface site portion or all adopt
Use all-steel cord as supporting material, carcass uses the radial of the fibrous materials such as nylon, polyester.Car tire is constituted：Tire
Face, band, belt, sidewall, the wear-resisting glue in rim of the mouth, carcass, inner liner, tyre bead, triangle rubber, rim of the mouth shield cloth etc..Tyre surface at present
The binding force of glue and filler is not high so that the earth-grasping force of tread rubber is inadequate, rolling resistance is big, since car tyre surface is generally using half
Steel wire meridian tread structure, tyre surface travel speed is high, and crown part rigidity is high, thickness is thin, and tyre surface is that tyre surface directly connects with road surface
Tactile position, subjects the most harsh external carbuncle effect of tyre surface, the wriggling very little between tyre surface and ground, tractive force and lateral force compared with
Often there is the phenomenon that tyre surface polishes, decorative pattern collapses flower and breach, leads to carcass explosion in height.Therefore, a kind of anti-skid wearable tire is invented
Face glue has positive effect to technical field of rubber preparation.
Invention content
Present invention mainly solves the technical issues of, it is not high for the binding force of current tread rubber and filler so that tread rubber
Earth-grasping force is inadequate, rolling resistance is big, since car tyre surface generally uses semi-steel wire radial tread structure, tyre surface travel speed
Height, crown part rigidity is high, thickness is thin, and tyre surface is the position that tire is in direct contact with road surface, subjects most harsh outer of tyre surface and answers
Force effect, the wriggling very little between tyre surface and ground, tractive force and lateral force are higher, often occur tyre surface polishing, decorative pattern collapse flower and
The phenomenon that breach, leads to the defect of carcass explosion, provides a kind of preparation method of anti-skid wearable tread rubber.

Stronger binding force is generated between glue and rock wool fibers, is formed very strong physical bond face or coherent boundary, is made aluminium oxide with thin
Layer form is present in rock wool fibers surface layer, since interface is smooth straight, when polytetrafluoroethylene (PTFE) bears load, can smoothly transmit
To rock wool fibers, in addition, aluminium oxide causes fibre property when can be loaded to avoid rock wool fibers as rock wool fibers protective layer
Damage, and complex reaction occurs for aluminium oxide and other organic principles, avoids generating uncontrollable and non-uniform Distribution brittlement phase,
To promote the toughness of tyre surface, the generation of breach is reduced；
（2）General tyre surface reinforcing agent directly adds carbon black, and carbon black is adsorbed on silicon in the carbon black silica gel in the present invention in tread rubber
In glue micropore, silica gel forms three-dimensional netted Si-O-Si structures after vulcanization in tire tread material, and script silica just has very well
Wearability, carbon black reticular structure cladding under enhance silica intensity, so that the wear-resisting property of tyre surface is further increased, lead to
Soybean oil is crossed by bentonite clay particle surface modification treatment, bentonite clay particle surface and Al after modification2O3Surface coupling forms
Silica long-chain, in mixing process, silica long-chain and PTFE long chains are entangled to each other, and interpenetrating has reached good couplingization,
The internal microstructure of composite material is set to change, strand regularity improves, and material surface energy is promoted, and leads to tyre surface over the ground
The earth-grasping force in face improves, the more difficult peeling of transfer layer that tyre surface generates in friction process, and make bentonite clay particle fills up effect increasing
By force, the wear extent for reducing tyre surface has a extensive future to promote the wear-resisting property of tire tread material.
