Description
One, technical field
The invention belongs to the chemometric techniques field, relate to standard matter preparing technology, particularly the technology of preparing of rubber standard substance.
Two, background technology
The vulcanization of rubber is an important process process of rubber industry production and processing, and by sulfuration, rubber becomes space network from linear structure, thereby obtains valuable physical and mechanical properties, becomes valuable construction material.The technological parameter of sulfidation is directly connected to the construction material quality.
Vulcameter is used for determining vulcanization parameters, is the requisite important tool such as rubber industry production, scientific research, exploitation.Vulcameter can be studied the sulfuration dynamics problem, carries out experimental formula; Vulcameter can produce in the caused curing curve variation of fine difference by starting material or the mix quality of each batch from produce, error in find producing, thus play the control product quality, enhance productivity, reduce scrap piece loss, reduce the vital role such as quality accident.
About the calibrating of vulcameter, China the Ministry of Chemical Industry has formulated specialized department's vertification regulation of a JJG (change) 101-91 in 1991, for rheometer.Use the multiple measurement verification utensils such as vernier caliper, outside micrometer, special-purpose torque calibration device, specific weight, dial gauge, stopwatch, Special temperature measurement device, load sensor in the rules, regularly (calibration interval are 1 year) calibrating instrument die cavity and rotor size, torque measurement system, frequency, temperature, mold clamping force etc., to a certain extent the amount of instrument passed to guarantee it is effective, even but but there is such subitem assay approval, the integrated performance index of instrument is qualified problem not necessarily.For example, the quality of the working condition of the die cavity elastic wall of instrument employing has a direct impact the result; The surperficial dirt of rotor, wearing and tearing; The amplitude angle is in long-term back and forth vibration, and angle loosening owing to machinery or that the torque increase causes the factors such as amplitude reduces changes; The work of register system is undesired etc.These factors can't find by subitem calibrating, but these factors all can exert an influence to the measurement result of instrument.And also do not have without the vertification regulation of rotor vulcameter is at present domestic.
The accuracy of vulcameter mainly proves by the moment of torsion standard.On the other hand, in order to prove the accuracy of vulcameter, will use sizing material before a kind of as the reference sizing material at a certain rubber size of test.Because rubber size does not possess enough bin stabilities usually, therefore, up to the present there is no the standard sizing material of recognition of state.Generally, rubber size is when room temperature storage, and curability will change.
The research about calibrating vulcameter standard substance has abroad obtained certain achievement, U.S. for example, in order to prove the accuracy of vulcameter, prepared especially a kind of styrene-butadiene rubber elastomeric compound as the reference sizing material that checks vulcameter, be stored under-10 ℃ the condition, but only in three initial middle of the month, the vulcanization characteristics of this elastomeric compound changes and can keep in allowed limits.
