Insulating paint formula based on nanoscale material and preparation and construction methods thereof

Abstract

The invention discloses an insulating paint formula based on a nanoscale material and a preparation and construction method thereof, and the formula comprises the following components by weight: 90 parts of nanoscale silicon dioxide; 10 parts of modified resin; and 10 to 50 parts of a diluent. The material has the functions of good insulating property, corrosion resistance, high weather resistance, high hydrophobicity, high temperature and low temperature resistance, wear resistance, high adhesive force, self-cleaning and good heat insulation effect, the whole production and construction process is free of pollution and harm to personnel, the raw materials can be stored and transported at normal temperature and can be configured and used on site, the environmental protection property is high, the cost is low, any equipment does not need to be replaced, the construction is convenient and the period (the functions needing to be achieved can be achieved within several hours) is short; the construction is low in environment and temperature and humidity requirements (the temperature ranges from-15 DEG C to-65 DEG C, and the humidity is below 98%) during construction; the detachment of painted objects is not required in many scenes, the application range is wide, and the application prospect is good.

Description

technical field [0001] The invention relates to a formula of insulating paint based on nano-scale materials and its preparation and construction methods, belonging to the technical field of power systems. Background technique [0002] At present, with the rapid development of the power system, various electric power, electrical equipment, and space insulation protection equipment have been widely installed and used. However, with the passage of time, and the harsh applicable environment (exposed, exposed, humid, etc.), various electrical, electrical equipment, and space insulation protection equipment will have different degrees of aging during use, as follows: [0003] (1) Switch cabinets and distribution boxes of substations and other cabinets or boxes that work on indoor power, electrical equipment and insulation protection equipment: [0004] The heat-shrinkable sleeves installed in various cabinets and busbars in the cabinets are easy to age. Insulators, wall bushings,...

AI Technical Summary

Problems solved by technology

[0008] The working environment is outdoors. The heat-shrinkable sleeve installed on the busbar is more prone to aging when exposed to the sun and rain. The connection of the busbar is wrapped with insulating rubber. Moisture can easily penetrate and cause loss of effect. Although the connection with the insulator is made of a special-shaped box However, the airtightness is not good, and the discharge phenomenon is easy to occur after the moisture enters, and even the busbar discharges the heat shrinkable sleeve, which has potential safety hazards

[0009] In view of the above-mentioned discharge and creepage problems, the corresponding equipment or parts are replaced, and heat shrinkable sleeves or other insulating parts are repackaged. The cost of replacement is too high, and the construction is very inconvenient
