Abstract

A method for preparing anti-icing paint for a power transmission cable includes the following steps that firstly, polytetrafluoroethylene resin, poly tridecylfluorooctyl acrylate, fluorosilicon resin, nano silicon dioxide, nano ferroferric oxide, nano cobalt sesquioxide and nano magnesium hydrate are conveyed to a ball mill and ground till the grain size is 20-40 nm and then mixed with sodium silicate for stirring, stirring is conducted for 40-50 min at the speed of 100-120 r / min, and a mixture is obtained after uniform stirring; secondly, remaining components are put into a reaction kettle, the temperature in the reaction kettle is kept constant to be 100-120 DEG C, even mixing and stirring are conducted at a stirring speed of 300-350 r / min for a stirring time of 20-30 min, and then the reaction kettle stands still for 4-6 h at normal temperature; thirdly, the mixture prepared in the first step is added into the reaction kettle and subjected to ultrasonic dispersing for 40-50 min, and the anti-icing paint is prepared.

Description

Technical field [0001] The invention relates to the technical field of coatings, in particular to a preparation method of anti-icing coatings for power transmission cables. Background technique [0002] With the rapid development of modern industry, the reliability requirements for power supply from the power grid are getting higher and higher. Ice and snow are a natural phenomenon, but icing of transmission cables is a natural disaster. The icing of lines seriously threatens the safe operation of the power system. Generally speaking, the icing of cables is formed due to various meteorological reasons, which mainly include factors such as temperature, humidity, convection of cold and warm air, circulation and wind speed. According to the formation conditions and the degree of damage, there are basic types such as rime icing, mixed icing, icy fog, hoarfrost, and snow. Among them, the mixed song is a compound icing process, first is rime, then rime, which is a form of alternating...
