Example Embodiment
[0034] Example 1
[0035] This embodiment relates to a protective coating applied to the surface of a solar panel support, including the following raw materials by weight: 20 parts by weight of thermosetting fluorocarbon resin, 13 parts by glycerol alkyd resin, 17 parts by acrylic resin, and 15 parts by modified epoxy resin , 6 parts of modified sepiolite, 2 parts of nano titanium dioxide, 1 part of sodium petroleum sulfonate, 2 parts of modified mica powder, 0.3 parts of multi-walled carbon nanotubes, 1 part of antioxidant, 2 parts of light stabilizer and 30 parts of solvent Servings,
[0036] The preparation method of the modified sepiolite is as follows:
[0037] (1) Pour the sepiolite and water mixture into the hydrothermal kettle, and add the surfactant, at a temperature of 200°C and a pressure of 2MPa, the reaction is kept under pressure and stirred, discharged and filtered to obtain a filter cake. After the filter cake is mixed with 7% hydrochloric acid, the reaction is stir...
