Embodiment

[0025] A kind of standard glue for calibrating rheometer, it comprises the component of following mass fraction: 100 parts of butyl rubber, 55 parts of carbon black, 15 parts of paraffin oil, 20 parts of active calcium, 1.5 parts of microcrystalline wax, 7.5 parts Active agent, 2.0 parts of release agent, 0.5 parts of insoluble sulfur, 5.5 parts of accelerator,

[0026] Among them, the butyl rubber adopts IIR1751 type (or IIR1675 type), and the main rubber adopts butyl rubber with good stability to the external environment as the main material, which is suitable for high-temperature mixing, and the filling factor is about 5-10% more than conventional rubber materials. In this way, the rubber compound produced by mixing has good dispersion, uniform performance and good stability;

[0027] Carbon black adopts N550 model, which is used as a reinforcing agent to improve the tensile strength of the rubber and adjust the hardness of the rubber; paraffin oil is used as a plasticizer ...

Abstract

The invention relates to standard rubber for checking a sulfur analyzer and a preparation method of the standard rubber. The standard rubber is applied to the technical field of checking of rubber compound testers, and comprises the following components in parts by mass: 100 parts of butyl rubber, 50-60 parts of carbon black, 15-25 parts of paraffin oil, 20-40 parts of active calcium, 7.5-12.5 parts of an active agent, 2.0-4.0 parts of a release agent, 0.5-2.0 parts of insoluble sulfur and 2-5.5 parts of an accelerant. The standard rubber has the effects that the data of the produced standard rubber is stable, the sulfur analyzer can be reversely calibrated by testing the data change of the standard rubber at the moment, so that the stability of the sulfur analyzer is predicted, and whether the sulfur analyzer needs to be cleaned and calibrated or not is determined by observing the fluctuation of the performance data of the standard rubber detected by the sulfur analyzer.

Description

technical field [0001] The invention is applied in the technical field of calibration of mixed rubber testers, and in particular relates to a standard rubber for calibration of rheometers. Background technique [0002] The production of any qualified product is inseparable from the process control and inspection of the produced product. In order to produce stable and high-quality products, inspection and testing is an indispensable and important control link. Strictly control the production process, the produced product must be a qualified and stable good product that meets the preset requirements. On the contrary, if the process is not controlled, there will be deviations in every link. In the end, a qualified and stable product will not be produced. This rule is also followed in the actual production of compound rubber. [0003] Existing performance testing of the processed rubber mix usually uses a rheometer to test the rubber mix, but when the rheometer has been used fo...
