Abstract
The invention discloses a kind of production method of tire tread glue, first pass through and spray drying after nano-cellulose suspension and natural rubber latex blending is obtained into the rubber combined powder of nano-cellulose, then using tetraethyl orthosilicate, MTMS as presoma, Surface coating is carried out to the rubber combined powder of nano-cellulose using sol gel process and obtains modified rubber powder, blending banburying, mill, vulcanizing treatment finally are carried out with raw materials such as reclaimed rubber, natural rubbers, obtains tire tread glue.Tire tread glue produced by the invention has the advantages of good mechanical performance, stability are high, production cost is low, and performance is good.
Description
Technical field
The present invention relates to reclaimed rubber technical field, more particularly to a kind of production method of tire tread glue.
Background technology
Tire tread glue as the sizing material that outermost tyre layers contact with road surface it is necessary to have the wearability of height, obdurability,
And certain heat resistance.With the development of automobile industry, the demand of tire tread glue is increasingly increased, and China's rubber provides
Source is relatively in short supply, and price is relatively expensive, therefore in actual production, partial regeneration rubber, one side energy are often mixed in sizing material
Enough economize on resources, environmental protection, on the other hand save cost.The processing procedure of reclaimed rubber is will to have vulcanized the rubber of (crosslinking)
Collagen material, usually rubber powder of waste tire are handled by mechanical crushing, then recover plasticity by desulfurization, due to regenerative process
Rubber cross key and main chain are cut off can simultaneously, cause reclaimed rubber structure necessarily to be destroyed, influence its mechanical performance, and
Easily ftracture, stability is poor.In order to meet the demand of actual use, the high tire of good mechanical performance, stability is obtained
Tread rubber to existing tread rubber production technology, it is necessary to be improved.
The content of the invention
The defects of the object of the invention is exactly to make up prior art, there is provided a kind of good mechanical performance, stability are high, raw
Produce the production method of the low tire tread glue of cost.
The present invention is achieved by the following technical solutions：
A kind of production method of tire tread glue, comprises the following steps：
（1）Nano-cellulose is first added to the water ultrasonic disperse and uniformly obtains nano-cellulose suspension, then by the Nanowire
Tie up plain suspension and natural rubber latex by volume 2：（0.5-1）It is well mixed, nano-cellulose-rubber is obtained after spray drying
Composite powder；
（2）By ethanol, glacial acetic acid, tetraethyl orthosilicate and MTMS by weight 100：（3-5）：（1-2）：（3-
5）It is mixed evenly to obtain mixed liquor, the water that then will be equivalent to the mixed liquor weight 2-4% is slowly dropped into the mixed liquor
In in 50-60 DEG C stir 1-2h, after cooling add equivalent to mixed liquor weight 10-15% the step of（1）The nano-cellulose-
Rubber combined powder is dispersed with stirring uniformly, and modified rubber powder is obtained after drying；
（3）By 20-40 parts by weight reclaimed rubber, the part by weight modified rubber powders of 10-20,60-80 parts by weight of natural rubber, 4-6
Part by weight of zinc oxide, 4-6 parts by weight stearic acid, 2-3 parts by weight accelerator, 1-2 parts by weight age resistor, 1.5-2.5 parts by weight sulphur
Sulphur, 6-8 parts by weight aromatic naphtha obtain tire tread glue by banburying, mill, vulcanizing treatment.
The solid content of the nano-cellulose suspension is 3-5%.
The solid content of the natural rubber latex is 30-40%.
The step（1）Middle spray drying condition is：150-180 DEG C of inlet temperature.
The Mooney viscosity of the reclaimed rubber is 80-120.
The step（2）Middle vulcanizing treatment condition is 155-165 DEG C, 8-12min.
It is an advantage of the invention that：
The present invention first passes through obtains nano-cellulose-rubber by spray drying after nano-cellulose suspension and natural rubber latex blending
Glue composite powder, then using tetraethyl orthosilicate, MTMS as presoma, using sol-gel technology to nanometer
Cellulose-rubber combined powder carries out Surface coating and obtains modified rubber powder, finally with the raw material such as reclaimed rubber, natural rubber
Blending banburying, mill, vulcanizing treatment are carried out, obtains tire tread glue.The present invention is first passed through in spray drying normal direction rubber powder
Nano-cellulose is introduced, improves the toughness and crack resistance of rubber powder, is then wrapped by sol-gel process on rubber powder surface
Siloxanes is covered, improves the mechanical performance and stability of rubber powder, when being processed with reclaimed rubber, natural rubber blending, rubber powder
End is uniformly distributed in the base, can be filled the defects of reclaimed rubber compatibility deficiency produces in the base, be improved tread rubber
Uniformity, and can improve the cracking resistance and stability of tread rubber.Tire tread glue produced by the invention has mechanical performance excellent
Good, the advantages of stability is high, production cost is low, performance is good.
