Example III
The silicon rubber composite material based on the modified retired silicon rubber insulator has the same steps and the same reagent and process parameters used in the steps, except that in the step (2), the addition amount of the modified silicon rubber particles is 100g.
Example IV

Comparative example one
A silicon rubber composite material based on a modified retired silicon rubber insulator comprises the following preparation steps: 20g of unmodified retired silicone rubber particles and 100g of vinyl silicone rubber are added into an open mill, the mixture is mixed for 10min at room temperature on the open mill, and the obtained mixed rubber is subjected to compression molding by a flat vulcanizing machine under the conditions of 170 ℃ and 20MPa and the vulcanizing time of 15min, so that a vinyl silicone rubber sample is obtained.

Performance test
1. The retired silicone rubber insulator particles and the modified silicone rubber particles in step (1) of example 1 were subjected to infrared spectroscopic detection, and the detection results are shown in fig. 2.
2. The tensile test was performed on a U-CAN UT-2060 stretcher with a test standard of GB/T528-2009, a test temperature of 25 ℃, a tensile speed of 500mm/min, and the tensile strength and elongation at break test results of the vinyl silicone rubber and the silicone rubber composites of examples 1-4 and comparative examples 1-5 are shown in Table 1.
TABLE 1 tensile test results for examples 1-4 and comparative examples 1-5
As can be seen from the performance test results of example 1 and comparative example 1 in table 1, the addition of the modified silicone rubber particles of the present application can improve the tensile properties of the silicone rubber composite material, while the addition of the unmodified silicone rubber particles can greatly reduce the tensile properties of the silicone rubber material, with a significantly increased degree of reduction compared to the tensile properties of the base vinyl silicone rubber.
As can be seen from the performance test results of example 1 and comparative example 2 in table 1, the vinyl silicone rubber is used as a matrix, the vinyl silicone rubber contains carbon-carbon double bonds, and a brand-new rubber composite material is prepared by compounding the vinyl silicone rubber under the action of high temperature based on the reaction between the double bonds of the vinyl silicone rubber and the carbon-carbon double bonds on the surfaces of modified silicone rubber particles; and the methyl ethyl silicone rubber has poor crosslinking effect with modified silicone rubber particles when the matrix is not formed.
As can be seen from the results of the performance tests of example 1 and comparative example 3 in Table 1, when the amount of nerol added in the preparation of the modified silicone rubber particles is too small, the surface modification effect on the retired insulator silicone rubber is poor, the double bonds grafted on the surface are too few, the effect of compounding with vinyl silicone rubber is reduced, and the tensile property of the product is reduced.
As can be seen from the performance test results of example 1 and comparative example 4 in table 1, too high temperature of the nerol pyrolysis decommissioning insulator silicone rubber can cause the decommissioning insulator to undergo self decomposition reaction under the higher temperature condition, thereby causing the performance of the modified silicone rubber particles to be reduced, and finally affecting the tensile performance of the product.
As is clear from the results of the performance test of example 1 and comparative example 5 in Table 1, when the amount of the modified silicone rubber particles added is too large, the dispersibility in the vinyl silicone rubber matrix is lowered, and agglomeration between particles causes stress concentration effect upon deformation of the material, resulting in lowering of the tensile properties of the product.
The foregoing embodiments have been provided for the purpose of illustrating the general principles of the present application, and are not to be construed as limiting the scope of the application. It should be noted that any modifications, equivalent substitutions, improvements, etc. made by those skilled in the art without departing from the spirit and principles of the present application are intended to be included in the scope of the present application.
