Description
Technical field
The present invention relates to a kind of sizing material environmental aging analog detection methods.
Background technique
Tire environmental aging is also known as thermo-oxidative ageing, and mechanism of action is that the effect of heat will accelerate rubber material crosslinking degradation etc.
Chemical change, macro manifestations are physical mechanical property change, and certain performances and ageing time are in single variation relation, such as pull apart and stretch
Long rate, stress relaxation coefficient, compression set rate etc..
Tire uses the time longer in actual use, in use often through heated, light, nitrogen oxygen, ozone etc. it is extraneous because
The effect of element, by the chemical composition of rubber material, the factors such as molecular structure and the change for causing rubber physical performance, this is one
The irreversible chemical change of kind.Once not only tire appearance will appear cracking for rubber aging, and tire tread glue is not wear-resisting, no
Resistance to thorn is easy to collapse and use up fastly, and the carcass of tire is easy to carcass caused by declining because of compound physical performance and comes to nothing, thus serious shadow
Ring the service performance of tire.Therefore condition simulation Acceleration study more demanding than use environment must be first carried out, in the prior art,
Common two methods once carry out simulation accelerated experiment:
Method one: tire is filled on wheel rim, after pouring 50/50 nitrogen oxygen mixed gas, tire and rim combination are put into
Into the ageing oven of certain steady temperature, and the assembly of tire and wheel rim is required every 1 weeks or taken out for 2 weeks, is cooled to certain
Its air pressure and the variation of oxygen content are measured after temperature, after pour new nitrogen oxygen mixed gas again to accelerate the variation of tire, always
Shi Changwei 7 weeks or 8 weeks.After the test, it checks tire appearance variation, and makees relevant physical property detection.
Method two: the rubber test piece vulcanizated is directly placed into ageing oven, it is desirable that ageing oven will have thermostatic, exhaust
Device.It is put between the sample in case the interval that have 50mm, pours oxygen, and test under heating pressurization, temperature generally adds
Heat is maintained at 0.6-07mpa to 70 DEG C of oxygen pressures, and the duration selects for 24 hours, in 48h, 72h, after arriving the defined time,
After parking 16-96h at room temperature, the related physical performance of re-test sizing material.
Detection method in the prior art has limitation (can not do sizing material aging) and expensive, and professional is needed to carry out
Detection, while the testing time is long.The environmental aging experiment of finished tire can only be wherein done in method one, method two can do sizing material
Environmental aging experiment, but it is only limited to hot air aging.
Therefore, it is necessary to propose effective technical solution, solve the above problems.
Summary of the invention
The present invention in view of the above shortcomings of the prior art, provides a kind of device simple, sizing material environmental aging mould at low cost
Quasi- test method.
The technical scheme to solve the above technical problems is that
A kind of sizing material environmental aging analog detection method, steps are as follows:
1) sizing material is vulcanized, the method for the present invention analog tests the environmental aging of different formulations sizing material；And vulcanization is completed
Film afterwards can be cut (such as dumbbell shape sample, rectangular specimen) according to different test items；
2) film after cutting is bonded to the groove centre of wheel rim, sample is uniformly at intervals in the wheel rim；And it is every
A film cannot be contacted with wheel rim, be spaced 50mm between each film；
3) tire to match with the rim size is installed, it is fit obtains tire, wheel rim and set of films；
4) compressed air will be poured in tire, the tire assembled is put into water tank at least 30 minutes, check tyre bead and
At valve cock whether gas leakage, such as parked at ambient temperature without gas leak phenomenon 24 hours or more, the compressed air in tire set
Change nitrogen oxygen atmosphere into (air pressure is selected according to tire sidewall allowable stress, needs to be adjusted with specific reference to experiment)；
5) above-mentioned tire, wheel rim and set of films zoarium are put into ageing oven, 65 DEG C aging eight weeks, wherein every two weeks again
It is primary to be filled with nitrogen oxygen atmosphere；
6) to above-mentioned steps after remove tire, film is removed from wheel rim and makees related property detection.
The utility model has the advantages that sizing material environmental aging simulation test of the present invention is first to carry out condition simulation more demanding than use environment
Acceleration study, the present invention can directly carry out the environmental aging test of sizing material, have good correlation, and method is simple, and applies
It is in extensive range.
Detailed description of the invention
Some specific embodiments of the present invention is described in detail by way of example and not limitation with reference to the accompanying drawings hereinafter.
