Problems solved by technology

Bird damage tripping accidents in North China Power Grid and Northwest Power Grid have accounted for 8-12% of abnormal power outages, causing huge losses
The currently used technical measures such as anti-bird thorns and bird repellents cannot be completely solved, and potential hazards such as overlapping of foreign objects in complex living areas also require a high-insulation technical measure

Embodiment Construction

[0021] The preparation process route and formula of the fluorosilicone rubber wire protection material are as follows:

[0022] Use 100 parts of dimethyl cyclic siloxane and 5~20 parts of trimethyl tris(Y-trifluoropropyl) cyclotrisiloxane, hydrolyze at 50 ℃, wash with water until neutral, then Let dry for 3 hours. Put it into the cracking kettle, add 1% catalyst KOH, polycondensate at an internal temperature of 140°C-160°C, evaporate the water, raise the temperature to 180°C, reduce the pressure to -0.095MPa, and receive the fraction at 99°C / 3mmHg . Use 100 parts of this fraction and 0.001-0.01% NaOH in a polymerization container to equilibrate telomerization at 130±5° C., and then remove NaOH to obtain a fluorosilicone base rubber containing fluorosiloxane linking units.

[0023] 100 parts of fluorosilicone base glue containing fluoropolysiloxane linking unit; gas-phase method SiO treated with hexamethyldisilazane hydrophobic treatment 2 30 parts; Al(OH) 3 20 parts; 2 par...

Abstract

The invention relates to a protective material of a guide wire. 100 portions of dimethyl annular siloxane and 5 portions to 20 portions of trimethyl tris cyclotrisiloxane are hydrolyzed under 50 DEG C, washed to be neutral, dried for three hours at 100 DEG C, and then put into a degradation reactor; 1 percent of catalyst KOH is added in to be polycondensed under the condition of 140 DEG C to 160 DEG C of internal temperature; water is vaporized, the temperature is raised to be 180 DEG C and the pressure is reduced to be -0.095MPa; 99 DEG C / 3mmHg distillate is received; 100 portions of the distillate and 0.001 percent to 0.01 percent of NaOH are adopted to receive balanced telomerization under 130 plus and minus 5 DEG C in a polymerisation container; the NaOH is removed to obtain fluorine base silicagel with fluorosilicone link unit; 100 portions of fluorine base silicagel with fluorosilicone link unit, 30 portions of gaseous-phase method SiO2 which receives hexamethyl disilazane hydrophobic treatment, 20 portions of Al(OH)3 and 2 portions of oligomerized polysiloxane structure control agent with hydroxyl group are stirred and kneaded for 3 hours under conditions of -0.09MPa vacuum and 180 DEG C of temperature in a closed container, and soaked overnight; afterwards, the product is added with 0.4 portion of curing ingredient in a two roll mill, roll smelted, remilled, continuously extruded and shaped at 160 DEG C, and sulfured for the second time for 2 hours at 180 DEG C, to obtain the protective material of the guide wire.

Description

technical field [0001] The invention relates to a protective conductor material for wires, which is a protective conductor material applied to the insulation protection of power transmission and transformation lines by utilizing the high insulation properties and good weather resistance of fluorosilicone rubber. Background technique [0002] At present, power transmission and transformation lines have frequent tripping and blackout accidents caused by bird damage. In recent years, with the great development of the national electric power industry, the number of transmission lines has increased significantly. In order to protect the environment, the number of birds has increased sharply. Bird damage tripping accidents in North China Power Grid and Northwest Power Grid have accounted for 8-12% of abnormal power outages, causing huge losses. The currently used technical measures such as anti-bird thorns and bird repellents cannot be completely solved, and potential hazards suc...
