The rubber preparation method of tearing strength promoting agent of the present invention, is characterized in that, including following work
Skill step：
A mixed onces, will precisely metering after rubber modified dose, wet ground sericite, aluminium hydroxide, protection wax, duff
Powder is thrown into homogenizer successively, is started blender and is stirred 50 seconds to 1 minute, is carried out raw material and is just mixed, reaches 50 seconds to 1 point
Clock is shut down；
Bis- mixing of b, the environmental-friendly rubber filling oil after accurate metering is thrown into the material of mixed once, starts stirring
Machine is again stirring for, and the 1 minute secondary agitation time to 1 point of i.e. shutdown in 20 seconds stops stirring；
C products release secondary mixture material in conveyer belt from blender, are sent in comminutor and are granulated, made
Grain is completed to send into storage tank blowing, metering, packaging to get product.
Compared with the prior art a kind of rubber tearing strength promoting agent of the present invention and preparation method thereof has
Have prominent substantive distinguishing features and a marked improvement, 1, preparation process it is simple, it is easy to operate, each original is summarized using compound technology
The peculiar general character of material enhancing tearing strength, is conducive to the production process of tire sidewall or other rubbers and product quality control
System makes sidewall rubber tearing strength improve more than 40%；2nd, it is environmentally friendly, three-waste free discharge（Because using Material cladding method and granulating technique
Waste water,waste gas and industrial residue may be not present）, energy-saving and emission-reduction, push away it is old innovation it is with obvious effects；3rd, raw material are easily purchased, and price is appropriate, tire

The rubber of the above embodiment of the present invention 1 tearing strength promoting agent, correlation properties and implementation result are as follows：
Characteristic：Non-toxic, harmless and pollution-free green new type rubber processing aid, to environment, to the person without it is any injury and
Pernicious gas overflows.
Application performance：10 parts are generally added in tire sidewall glue mixing formula, it is any without being done to other mixed materials
Adjustment.
The effect of highly significant is played in the application of tire sidewall glue, the dynamic property in sidewall rubber contrast test is torn
The more former sidewall formula tearing strength of resistance to spalling improves more than 40%.
Contrast and application test is carried out in the performance of all-steel load-bearing radial tire sidewall, table Central Plains sidewall is existing tire
Side glue, new sidewall are the sidewall rubber for the tearing strength promoting agent for adding in embodiment 1；Sidewall glue formula is as follows：
From table 1 it follows that former sidewall and new tyre side basic recipe are unchanged, only 10 are increased in new sidewall formula
The tearing strength promoting agent of part embodiment 1.
Test result is as follows：
Before aging（It is static）Performance comparison test's data are shown in Table 2.
Conclusion：From Table 2, it can be seen that the new sidewall of small compatibility test has compared with than former sidewall tearing strength in a static condition
It improves by a small margin, but aniseed experiment in workshop is not ideal enough, tearing strength is declined slightly instead, and test data shows performance before aging
The not very success of contrast test tearing strength promoting agent, but be not most important in rubber experiment and in practice production before aging
The problem of, because being that in a static condition, what technical staff was critical to is the related data obtained under dynamic condition after aging, always
Test data is shown in Table 3 after change.
Conclusion：It is shown from table 3 by data, either small matching property contrast test or workshop aniseed after aging
Energy comparative test result is all ideal, and especially aniseed performance comparison test's result is even more exciting between aging rear car, tears
Resistance to spalling exceeds more than 40%, the anti-odds that can significantly reduce tire and tire scrappage caused by due to quality problems,
Can be that tiremaker saves a large amount of economic loss, while can also extend the service life of tire, economic benefit and society imitate
Yidu is of great significance, and has promising application prospect.
Specific embodiment described herein is only an example for the spirit of the invention.Technology belonging to the present invention is led
The technical staff in domain can do various modifications or additions to described specific embodiment or replace in a similar way
Generation, but not deviate the spirit or beyond the scope of the appended claims of the present invention.
