However, due to contact angle (water): 90°-110°, rolling angle (water): >60°, contact angle (oil): 70°, (Note : The contact angle is large and the rolling angle is small, indicating that the material has good hydrophobicity and the corresponding anti-icing ability is strong); it also leads to its resistance to special pollution (cement, coal ash, bird droppings and special pollution salt spray, oil mist moss, etc.) No resistance, poor hydrophobic mobility, increasing the probability and frequency of pollution flashover of insulation equipment

Embodiment 1
[0030] Embodiment 1: A kind of coating and preparation method that transmission line is used
[0031] The component distribution ratio involved in the present embodiment 1 is the optimal value of the present invention.
[0032] figure 1 The manufacturing process of the coating for the transmission line of the present embodiment is shown
[0033] 1. The coating used for the transmission line of this embodiment is made by mixing a primer and a top coat, and adopts a construction method of one bottom and one side.
[0034] 1) The primer is two-component, consisting of primer A component, primer B and diluent, stirred, and the dispersion process (that is, the process of dispersing a uniform paint mixture) at a stirring speed of 2000rpm or more is made into a primer.
[0035] Component A of the primer is composed of raw materials fluorosilicone resin (40%), silica filler (10%), ethyl acetate solvent (40%), dispersant (3%), defoamer (2%), It is composed of joint agent (2.5%) and ...
Embodiment 2
[0043] Embodiment 2: the coating that transmission line is used and manufacture method
[0044]The coating and manufacturing method of this embodiment 2 is basically the same as that of embodiment 1, the difference lies in the proportioning range between the components involved, which is controlled within 2% of the given weight proportion value in embodiment 1.

Abstract
The invention discloses a coating for a power transmission line and a preparation method of the coating. The coating is composed of 50 wt% of a primer and 50 wt% of a finish. The primer is composed of a primer A, a primer B and a diluent, the ratio of the primer A to the primer B is 1: 1, the diluent is determined according to the total weight of the primer A and the primer B, and the viscosity is adjusted to 15-25 s; the finishing paint is prepared from an alcohol solvent and super-hydrophobic SiO2 nano functional liquid. And preparation of the super-hydrophobic SiO2 nano functional liquid: adding a basic catalyst and silicate ester into a high-purity organic solvent, carrying out stirring reaction and aging, and adding a fluorine-containing organic matter to obtain the super-hydrophobic SiO2 nano functional liquid. The coating disclosed by the invention has a unique light absorption characteristic, so that the coating is extremely easy to deice even in an environment at the temperature of subzero, and the anti-icing function of the material is realized; the service life of the super-hydrophobic function is prolonged while the durability is improved, and the super-hydrophobic coating is particularly suitable for spraying protection of power equipment in areas such as mountainous areas, hills and forests.
Description
technical field [0001] The invention belongs to coating technology, specifically, a super-hydrophobic, self-cleaning, anti-fouling, anti-icing coating used for power grids, power generation and transmission lines and a preparation method thereof. Background technique [0002] Paint is a chemical product with a wide range of uses. According to different performances and uses, coatings are divided into luminescent coatings, sound-absorbing coatings, heat-insulating coatings, automotive coatings, building exterior wall coatings, interior wall environmental protection coatings, etc. For high-voltage lines such as transmission lines, iron towers, poles, and insulators, the coatings used need to have super-hydrophobic, super-oleophobic, super-self-cleaning, super-hydrophobic (oil) functions in high-humidity environments, and natural light absorption. In the natural environment, the coating can have the properties of delaying icing, reducing the amount of icing, easy deicing, and ...
