Determination of vinyl content of methyl vinyl silicone rubber
Near infrared method
1 Scope
This standard specifies the method for determining the vinyl content (vinyl mole fraction) of methyl vinyl silicone rubber by near-infrared method.
The vinyl content ranges from 0.04% to 5.00%.
This standard applies to methyl vinyl silicone rubber copolymerized with a dimethylsiloxane ring and methyl vinylsiloxane.

3 Terms and definitions
The terms and definitions defined in GB/T 29858 apply to this document.
4 Principle
Near-infrared spectroscopy uses chemical bonds such as hydrogen-containing groups XH (X=C, N, O) at wavelengths from 780 nm to 2500 nm.
The characteristic spectrum generated by vibration or rotation, the stoichiometric method is used to establish a quantitative model for predicting vinyl content, and the model is determined by model
Vinyl content in vinyl-based silicone rubber.
5 instruments and calibration samples
Near-infrared spectrometer. Random software has the functions of collection, storage analysis and calculation of near-infrared spectral data, which can establish reliable settings.
For the standard model, an integrating sphere module or a transmissive module is required, and an accessory with a fixed optical path quartz surface is included. Should comply with GB/T 29858 instrument
Claim.
Calibration sample. low vinyl content methyl vinyl silicone rubber sample with a vinyl content of 0.04% to 0.30% and 0.30%~
5.00% high vinyl vinyl silicone rubber sample.
6 Analysis steps
6.1 Instrument preparation
Before the measurement, the instrument preheating and self-testing are carried out according to the requirements of the near-infrared analyzer manual.
