Problems solved by technology
Inorganic silicidation will directly lead to the decrease of surface hydrophobicity and mechanical properties, so that the safety of product operation cannot be guaranteed
[0003] For the evaluation method of the degree of inorganicization, X-ray diffraction energy spectroscopy (XPS) is mainly used to characterize it at present, but the XPS detection time is long and the detection requirements are high, which cannot meet the actual needs of on-site detection. It can be said that silicone rubber products are inorganic The standardized evaluation system is immature, it is necessary to study new methods and apply them

The invention discloses a method for evaluating the aging degree of silicone rubber through the inorganic degree, wherein the method comprises the following steps: 1, selecting a silicone rubber product to be tested as a test sample, and selecting inorganic SiO2 as a control sample; 2, carrying out infrared spectrum characterization on the test surface of the test sample and the surface of the control sample by using an infrared spectrometer to obtain an infrared characteristic spectrogram of Si-O-Si of the test sample and an infrared characteristic spectrogram of inorganic SiO2; and step 3, judging the inorganic degree of the silicone rubber product according to the displacement difference of the infrared characteristic peak of Si-O-Si relative to the infrared characteristic peak of inorganic SiO2 on the wave number, and further evaluating the aging degree of the silicone rubber product through the inorganic degree. According to the method, the surface inorganic degree of the silicone rubber product is represented by the infrared spectrometer, the aging degree of the silicone rubber product is evaluated through the inorganic degree, the operation is simple, the result can be obtained through simple subtraction formula calculation, and the result is objective and reliable.
Description
technical field [0001] The invention relates to the technical field of high-voltage insulation detection, in particular to a method for evaluating the aging degree of silicone rubber through the degree of inorganicization. Background technique [0002] Silicone rubber products have the advantages of light weight, good stain resistance, and convenient maintenance, and are widely used in the field of high-voltage insulation. But since silicone rubber is a class of -CH 3 For polymer materials with side chains and Si-O-Si main chains, under the joint action of high temperature, ultraviolet light, humidity and other conditions, the main and side chains will inevitably break and age. Aging will be accompanied by many aging characteristics, such as decreased elongation at break, increased hardness, inorganic siliconization, etc., among which inorganic siliconization is one of the important characteristics in the aging process. Inorganic silicidation will directly lead to the decr...
