Abstract

The invention discloses a protective coating applied to the surface of a solar panel bracket. The protective coating applied to the surface of the solar panel bracket is prepared from the following raw materials in parts by weight: 20 to 30 parts of thermosetting fluorocarbon resin, 13 to 18 parts of glycerin alkyd resin, 17 to 26 parts of acrylic resin, 15 to 25 parts of modified epoxy resin, 6 to 13 parts of modified sepiolite, 2 to 4 parts of nano-titania, 1 to 3 parts of petroleum sodium sulphonate, 2 to 5 parts of modified mica powder, 0.3 to 0.8 part of multi-walled carbon nano-tubes, 1to 2 parts of an antioxidant, 2 to 4 parts of a light stabilizer and 30 to 50 parts of a solvent. According to the protective coating applied to the surface of the solar panel bracket provided by theinvention, the prepared coating has good adhesion force, strong acid resistance and alkaline resistance, and excellent anti-aging performance by controlling the types and the proportions of the raw materials.

Description

technical field [0001] The invention belongs to the technical field of solar panel supports, and in particular relates to a protective coating applied on the surface of a solar panel support and a preparation method thereof. Background technique [0002] The solar bracket is mainly used to support and fix the solar panel. Because it is exposed to the outside for a long time, it is necessary to have good corrosion resistance. At the same time, the weather is cold and the temperature is low. Fracture or frostbite or damage to the surface of the stent. [0003] The invention patent of application publication number CN107474671A discloses a coating for solar support, which is formed by spraying the coating on the solar support after stirring evenly, and drying naturally for 90-120 minutes; the coating includes the following raw materials: propylene glycol, ethyl alcohol Glycol, glycerol, modified PTFE emulsion, silicone acrylic emulsion, ethyl acetate, deionized water, leveling...
