Description

technical field [0001] The invention relates to a coating, in particular to a high-temperature and abrasion-resistant ultra-high voltage insulating coating and a preparation method thereof. Background technique [0002] With the advancement of science and technology, electrical products are developing in the direction of small size, light weight, high efficiency, large capacity, simulation and intelligence. As a result, the conditions of use of insulating materials and the diversification of the use of the environment. [0003] With the development of the coatings industry, some organic coatings can no longer meet people's ideas of environmental protection, multi-functionality and excellent performance. In some electrical and electronic industries, insulation and fire protection requirements are required, that is to say, insulation must be able to withstand high enough temperatures. Existing coatings used on electrical and electronic products either meet the requirements f...

AI Technical Summary

Problems solved by technology

Existing coatings used on electrical and electronic products either meet the requirements for insulation performance but cannot withstand high temperatures, or can withstand high temperatures but have insufficient insulation performance, which causes the insulation and heat resistance of electrical and electronic products to be insufficient. Requirements, for example, there is a kind of protective ring on the electrode terminal of the motor product, which is required to be resistant to high temperature caused by conduction and heat, and has good insulation performance. This kind of protective ring is widely used in motor products in various industries, but currently the general production Manufacturers, the protective ring either meets the requirements of insulation performance, but cannot withstand high temperature, or can withstand high temperature, but the insulation performance is not ideal

[0004] In the current industry, there are many types of insulating coatings. Due to the differences in the formulation and processing technology of the coatings, the performance of the insulating coatings is also uneven. Therefore, how to improve the mechanical strength and chemical stability of the insulating coatings, and improve the mechanical impact and resistance of the coatings. Thermal shock performance, improving the performance of coatings to withstand strong electric fields without being broken down is a problem to be solved in this industry. Chinese patent number: CN103571329A discloses an insulating and anti-corrosion coating. Composed of alumina, flame retardant, cermet particles, calcium sulfate, zinc oxide, silicon nitride, and deionized water. At the same time, ceramic particles need nano-scale materials, and the preparation cost is relatively good. At the same time, because its components contain more metal oxides There is a risk of electrical conductivity in long-term use, and the paint of this invention is brittle and easy to crack, and there are hidden dangers in long-term use

"An insulating coating for overhead high-voltage wires and its preparation method" provided by the notification number CN101781498B uses polytetrafluoroethylene resin and other fillers to prepare the coating, which has excellent properties of self-cleaning, anti-snow, and high-voltage resistance. Fully consider the high temperature resistance and thermal conductivity of the coating, which is not conducive to the heat dissipation during the working process of insulating materials
