Description
Technical field
The invention discloses a kind of preparation method of wear-resistant tyre, belong to rubber industry preparing technical field.
Background technology
Tire is the annular elastic rubber product rolled in various vehicles or the ground connection mechanically assembled.1845, go out
It is born in Scottish civil engineer's Thomson and has invented pneumatic tire, and with《The wheel of carriage and other vehicles is improved》To inscribe,
Obtain the patent of British government.December 10 the same year, first pneumatic tire was born.Tire is typically mounted in alloy rim,
Vehicle body can be supported, buffers foreign impacts, the contact with road surface is realized and ensures the driving performance of vehicle.Tire is often complicated and severe
Used under conditions of quarter, it subject in motion various modifications, load, power and high/low temperature effect, it is therefore necessary to have compared with
High load-carrying properties, hauling ability, shock-absorbing capacity.Meanwhile also require possess high-wearing feature and flexible resistance, and low rolling
Resistance and heat generation.The half that the world consumes rubber mass is used for tire production, it is seen that the ability that tire consumes rubber is not insignificant.
Tire is one of most important building block on automobile, and its effect mainly has：The total weight of vehicle is supported, is held
By the load of automobile；Transmission traction and the torsion of braking, ensure wheel and the adhesive force on road surface；Mitigate and absorb automobile and travelling
When vibrations and impulsive force, prevent auto parts and components by strenuous vibration and earlier period damage, adapt to the high speed performance and drop of vehicle
Noise when low row is sailed, ensure security, control stability, comfortableness and the energy saving economy of traveling.
China tire national standard, U.S.'s tyre rim handbook, European tyre wheel rim standard, Japanese tire standards with
And all classified in international tire standards with purposes, following several types can be divided into：Tyres for passenger cars is loaded on car
Tire, it is mainly used in high speed driving in good road surface；Light truck tire be often referred to 16 inches of rim diameter and its
The truck tyre of following section wide 9 inches and its above；Off-the-road tyre off-the-road tyre is to be loaded on specificity
On the engineering machinery vehicle of operation；Cross-country vehicle tire offroad vehicle is front and rear wheel drive；Agricultural and forestry machinery tire are agricultural
Tire mainly uses on tractor, combine united reaper and agricultural machinery and implement vehicle.
Therefore, invent a kind of wear-resistant tyre has positive effect to rubber system for technology industry.
The content of the invention
Present invention mainly solves technical problem, the defects of for current tire wear resistance difference, there is provided a kind of wear wheel
The preparation method of tire.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：
A kind of preparation method of wear-resistant tyre, it is characterised in that specifically preparation process is：
（1）400~500g bark of eucommia dry fruits are weighed, are put into glass guide channel, are done with 300~400mL sodium hydroxide solutions immersion bark of eucommia
Fruit, filter off except filtrate obtains filter residue, filter residue is washed with water, the filter residue after being washed；
（2）Toluene is mixed with the filter residue after washing, is placed in evaporation reflux, phegma is obtained after backflow, by phegma
Load conical flask, be put into heat temperature raising in baking oven, be dried to obtain thick glue；
（3）Weigh the rice-straw ash after 100~150g hydrocarbon black powders, the burning of 200~250g straw to be placed in beaker, add into beaker
Enter 200~250mL sodium hydroxide solutions, after stirring, then 200~300mL hydrochloric acid is added into beaker, and beaker is heated and risen
Temperature, stirring, obtains carbon black silica gel；

Mixing time 3~5 minutes after sodium hydroxide solution, the mass fraction of hydrochloric acid is 20%, and temperature is 80~85 after beaker heat temperature raising
DEG C, mixing time is 10~15min after adding hydrochloric acid.
Step（4）Described first time adjustment roll spacing is 2~4mm, and roller temperature is maintained at 70~80 DEG C, plasticated for the first time the time
For 3~5min, it is 0.5~1.0mm that second, which adjusts roll spacing, and the time of plasticating for the second time is 1~3min.
Step（5）The described temperature for controlling vulcanizer is 145~155 DEG C, and the close certain temperature of mould is 150 DEG C,
The pressure of pressurization is to 9.8~10.2MPa.
The beneficial effects of the invention are as follows：
（1）The auxiliary rubber gutta-percha added in the wear-resistant tyre of the present invention is compared with natural rubber, both molecular chain configurations
Difference, natural rubber are cis-polyisoprene, and gutta-percha is trans-polyisoprene, and it is qualitative very big that this results in both
Difference, natural rubber are soft and flexible, and gutta-percha is the rigid plastics easily crystallized, and gutta-percha is in natural rubber and along fourth
Make spring chain during tire force that molecule sliding occur on rigid chain through vulcanization crosslinking in rubber, reduce the consumption of tire interior energy, from
And reach the effect for making tire wear；
（2）General tire reinforcing agent directly adds carbon black, and the carbon black silica gel in wear-resistant tyre of the present invention adsorbs carbon black in silica gel
In micropore, silica gel forms three-dimensional netted Si-O-Si structures after vulcanization in tire material, and script silica just has well
Wearability, carbon black enhance silica intensity under network structure cladding, the anti-wear performance of tire is further improved.
