Abstract

The invention discloses an ice coating prevention power transmission cable paint for a power transmission cable and a preparation method thereof. The ice coating prevention power transmission cable paint is prepared from nanoscale inorganic particles, a silane coupling agent, a wetting dispersant, a leveling agent, a thickener, fluorine-modified acrylic resin and a solvent; and by using the solvent as the base, the components are respectively 1 to 5 percent, 1 to 3 percent, 1 to 5 percent, 0.1 to 0.5 percent, 1 to 3 percent and 2 to 7 percent of the solvent in percentage by weight. The preparation method of the ice coating prevention paint for the power transmission cable comprises the following steps: firstly, uniformly dispersing the nanoscale inorganic particles, the silane coupling agent and the wetting dispersant into the solvent by utilizing mechanical stirring and ultrasound; then adding the leveling agent, the thickener and the fluorine-modified acrylic resin into the mixed solution; and uniformly dispersing each component by utilizing mechanical stirring and ultrasound. After the ice coating prevention paint for the power transmission cable is coated on the power transmission cable, the power transmission cable has functions of staining resistance and ice coating prevention.

Description

technical field [0001] The invention relates to a hydrophobic coating, in particular to an anti-icing coating for power transmission cables and a preparation method thereof. Background technique [0002] The icing of transmission lines threatens the safe operation of power and communication networks. In recent years, many scholars have studied how to de-ice the power system. Studies have found that the use of hydrophobic coatings can prevent transmission lines from being iced, and can also prevent transmission lines and insulators from pollution flashover and ice flashover. This method prevents icing without additional manpower and material resources, and helps reduce the cost of ice disaster prevention and control. But in the outdoor environment, organic oil pollution often has a bad influence on the hydrophobicity of the cable coating. The hydrophobicity of hydrophobic materials is determined by their low surface energy and rough surface structure. Organic oil stains ar...
