example
[0059] Taking a high-temperature vulcanized silicone rubber sample as an example, its formula is: 100 parts of polydimethylsiloxane, 185 parts of aluminum hydroxide filler, and 35 parts of silica filler. It can be known that the total mass of the filler is 100 parts, so the rubber content It is 100 / (220+100)=0.3125.
[0060] Utilize the attenuated total reflection-Fourier transform infrared spectroscopic analysis method to obtain its infrared spectrum, such as figure 2 shown.
[0061] Atlas, I 792 =0.1593, I 1018 =0.25649, substituting into equation (1) can obtain the glue content to be 0.317266, but the glue content of the actual sample is 0.3125, the calculation error of the equation is:

The invention discloses a silicone-rubber rubber-content detecting method based on an infrared spectroscopic analysis method.The silicone-rubber rubber-content detecting method is characterized by including the following steps that a, an infrared spectroscopy absorption spectrum of a silicon rubber sample is detected; b, the absorption peak value at the specific absorption wave number position of the detected infrared spectroscopy absorption spectrum of the silicon rubber sample is measured; c, the rubber content of the silicon rubber sample is calculated based on the absorption peak value at the specific absorption wave number position of the detected infrared spectroscopy absorption spectrum of the silicon rubber sample.The result can be used for judging the aging degree and the running state of silicon rubber materials, and the silicone-rubber rubber-content detecting method has the advantages of being reliable, accurate, portable and nondestructive.
Description
technical field [0001] The invention relates to a method for detecting the content of silicon rubber based on an infrared spectrum analysis method. Background technique [0002] Silicone rubber materials are widely used insulating materials in power grid systems. Devices and products made of silicone rubber materials include but are not limited to composite insulators, anti-pollution flashover coatings, cable terminal accessories, etc. However, silicone rubber is an organic polymer material, which is susceptible to aging due to external environmental stress during long-term operation. High temperature vulcanized silicone rubber is the most widely used insulating material in power systems. Some high-temperature vulcanized silicone rubber insulation materials have poor aging resistance due to the raw materials or poor craftsmanship used. The main components of silicone rubber are polydimethylsiloxane, white carbon black, and aluminum hydroxide fillers, and the proportion of ...
