The safety signboard is frequently used on a transformer substation site, and can play a warning role for site workers. For example, hanging "stop step, high pressure hazard!on a barrier adjacent to the live equipment at the construction site! "sign board, hanging on the work site or service equipment"! "Nameplate". At present, a signboard in a transformer substation is mostly made of pure plastic or plastic with magnetic attraction and soft magnetic materials, and is attached with a rope for suspension. When the safety measures are arranged, the power transformation operation and maintenance personnel can adopt an adsorption mode for the cabinet made of ferromagnetic materials, but can only adopt transparent adhesive tape to paste or find hanging points to hang the signboard for the cabinet made of non-ferromagnetic materials. Therefore, the signboard is easy to swing or fall off under the windy condition, the use of the signboard is influenced, and the waste of manpower and materials is also caused.

Wherein the silane coupling agent is KH 550. Wherein the cross-linking agent is methyl triacetoxysilane.
And adding the raw materials into a rubber mixing mill for mixing and vulcanizing to prepare the viscous material sample.
Example 1 Performance testing of samples prepared
1. Adhesion Performance test
Since the production site nameplates are used on average 24 hours/time, the viscous material chosen must have a high viscosity.
The adhesion contrast test experiment selects a non-ferromagnetic material cabinet which is common on a transformer substation site, a soft magnetic safety sign board which is used on the site, a 10cm by 10cm finished product sample of the embodiment 1 and a 10cm by 10cm transparent adhesive tape. And comparing by counting the separation time of the nameplates.
When the simulated environment was set to no wind and no rain, and the ambient temperature was 23 ℃, the duration of use of the finished experimental group of example 1 was 73 hours, while the duration of use of the scotch tape reference group was 52 hours.
When the condition that the simulated environment only changes the wind power level is set as 5-level strong wind, the service life of the experimental group is 52 hours, and the service life of the reference group is 13 hours; when the simulated environment only changes the condition of rainfall level and is set as medium rain, the service life of the experimental group is 48 hours, and the service life of the reference group is 14 hours; when the simulated environment was set to 35 c, which is a condition in which only the ambient temperature was changed, the use period of the experimental group was 40 hours and the use period of the reference group was 14.5 hours.
Experiments show that the finished product sample of the organic silicon rubber selected by the invention can meet the requirement of long service life no matter in a severe environment or a good environment, and is superior to the traditional method.
2. Test of ductility
The production site nameplates are frequently used, and according to statistics, the average frequency of use of each nameplate is 65 times/year, and in consideration of the convenience of use, the selected adhesive material has to have good ductility and difficult deformation.
The tensile properties test tests were conducted to measure primarily the degree of elongation and the corresponding length of recovery of a 10cm x 10cm sample of the finished silicone rubber of example 1. When the maximum stretching degree reaches 80%, the average recovery time is 9.2 seconds, the use times can reach more than 200 times, and no crack appears. And with the commercially available silicone rubber adhesive product as a reference, when the degree of stretching reached 80% at the maximum, the average recovery time was 15.5 seconds and more cracks were generated from the use times to 200 times, as compared with the sample of comparative example 1, when the degree of stretching reached 80% at the maximum, the average recovery time was 12.3 seconds and fine cracks were generated from the use times to 200 times. Experimental results show that the finished product sample of the organic silicon rubber with the selected parameters has good ductility and convenience, can be repeatedly used for many times, and can meet the field use requirements.
3. Aging Performance test
The aging performance test experiment mainly comprises a temperature and humidity circulation experiment.
Temperature cycling experiments were used to test the extent to which viscous materials can be tolerated in a continuous environment of alternating high and low temperatures. The salt spray corrosion test box is used for the experiment, the test time is 5 hours, and the test temperature cycle is 0-100 ℃. The test was carried out with the sample of example 1: the adhesive material had a tensile strength change of 61.4%, an elongation at break change of 31.9%, and a 300% stress at break change of 42.1% at a temperature change of 10 ℃/min, a tensile strength change of 34.2%, an elongation at break change of 27.6%, and a 300% stress at break change of 26.8% at a temperature change of 15 ℃/min, a tensile strength change of 25.5%, an elongation at break change of 25.1%, and a 300% stress at break change of 20.3% at a temperature change of 30 ℃/min.
And a salt spray corrosion test box is used by taking a commercial organic silicon rubber bonding product as a reference group, the test time is 5 hours, and the test temperature cycle is 0-100 ℃. When the temperature change rate is 10 ℃/min, the viscous material tensile strength change rate is 48.5%, the elongation at break change rate is 29.4%, and the 300% stress at break change rate is 38.3%, when the temperature change rate is 15 ℃/min, the viscous material tensile strength change rate is 28.1%, the elongation at break change rate is 22.4%, and the 300% stress at break change rate is 19.9%, when the temperature change rate is 30 ℃/min, the viscous material tensile strength change rate is 21.7%, the elongation at break change rate is 21.9%, and the 300% stress at break change rate is 15.4%.
By contrast with comparative example 1, a salt spray corrosion test chamber was used, the test duration was 5 hours, and the test temperature cycle was 0 ℃ to 100 ℃. The adhesive material had a tensile strength change of 55.4%, an elongation at break change of 28.4%, and a 300% stress at break change of 37.1% at a temperature change of 10 ℃/min, a tensile strength change of 30.7%, an elongation at break change of 29.1%, and a 300% stress at break change of 21.3% at a temperature change of 15 ℃/min, a tensile strength change of 23.1%, an elongation at break change of 22.4%, and a 300% stress at break change of 18.6% at a temperature change of 30 ℃/min.
4. Insulating property
Table 1 conductivity testing of the samples of each group
Wherein the resistivity of the insulating material for engineering applications is generally not less than 109Ω·cm。
5. Preservation and method
In order to ensure the service life of the finished product of the organic silicon rubber, the finished product of the organic silicon rubber is stored in a shady, cool, lightproof and dry environment, and layered subpackaging is required to be carried out during storage for the convenience of next use.
When the silicone rubber is used, a user can select the number of finished silicone rubber products according to the field environment. When the wind power of the external environment is less than 5 grade, the rainfall is below 10mm within 24 hours, the temperature is below 30 ℃, and the using time is within 72 hours, an organic silicon rubber finished product can be adhered to the safety sign and then attached to the on-site cabinet. When the wind power level, the rainfall amount, the temperature and the use time are increased, the number of finished products of the silicone rubber for sticking can be increased appropriately.
The viscous material prepared from the organic silicon rubber can solve the problems that a field safety signboard is easy to fall off and has no place to hang, and the like, is convenient to use and store, and can be repeatedly used for many times. The viscous material can be used as a supplement of a traditional suspension method, and the safety management level of a transformer substation field is improved.
