Problems solved by technology

[0002] With the continuous improvement of the national infrastructure, the supporting power transportation is also spread all over the country. There will be a large number of joints in the process of power transportation. If there is an obvious failure of the joints, there will be arcs or electric sparks, which will cause the temperature in the area to rise sharply, resulting in damage to the joints. , if it is not repaired, it will lead to other dangerous situations and even cause the grid to be paralyzed

Embodiment 1

[0024] The preparation method of the polyimide label material of power system failure identification, comprises the following steps: (1) after mixing ammonium manganese phosphate powder, dioxane and dimethylacetamide with the ratio of 10:30:60, add to In a ball mill, grind it to a dispersion solution of ammonium manganese phosphate powder with a particle size of 3-7 μm; the coating solution includes: polyurethane glue, white luminous powder, titanium dioxide (particle size less than or equal to 10um), and the mass ratio is 100:1.2: 3. Mix well;

[0025] (2) Add the dispersion liquid to the coating liquid, mix and stir in the ratio of dispersion liquid: coating liquid: coating liquid curing agent=15:85:3;

[0026] (3) Coat the mixed solution prepared in step 2 on a black polyimide film with a 200-mesh gravure roller, and dry it in an oven at 120° C. for 1 min, with a coating thickness of 3 μm;

[0027] (4) Add 30% polyisocyanate into the acrylate solution in a ratio of 100:2, ...

Embodiment 2

[0030] Same as Example 1, except that the coating solution includes: polyurethane glue, white luminous powder, and titanium dioxide, in a mass ratio of 100:1.4:2.

Embodiment 3

[0032] Same as Example 1, except that the coating solution includes: polyurethane glue, white luminous powder, and titanium dioxide, in a mass ratio of 100:1:4.

Description

technical field [0001] The invention belongs to the field of label materials, and in particular relates to a polyimide label material used for power system fault identification and a preparation method thereof. Background technique [0002] With the continuous improvement of the national infrastructure, the supporting power transportation is also spread all over the country. There will be a large number of joints in the power transportation process. If there is an obvious failure of the joints, there will be arcs or electric sparks, which will cause the temperature in the area to rise sharply, resulting in damage to the joints. , If it is not repaired, it will lead to other dangerous situations and even cause the power grid to be paralyzed. Contents of the invention [0003] The invention provides a polyimide label material used for power system fault identification and a preparation method thereof. The surface of PI is coated with a polyurethane coating liquid containing ...
