Thermal-insulation extra-high voltage flame-retardant coating and preparation method thereof

Abstract

The invention provides a thermal-insulation extra-high voltage flame-retardant coating and a preparation method thereof. The coating comprises, in parts by weight, 50-65 parts of resin, 10-20 parts of borax, 5-8 parts of boric acid, 0.5-3.5 parts of natural camphor, 0.1-0.5 parts of a coupling agent, 12-18 parts of nanofiller, 30-40 parts of a solvent, 1-3 parts of a plasticizer, 1-3 parts of an anti-settling agent, 2-4 parts of a dispersing agent and 0.2-0.4 parts of a defoaming agent. The thermal-insulation extra-high voltage flame-retardant coating has the good flame retardance, the high mechanical properties and the good electrical insulating property, the preparation technology is simple, and raw materials are easy to obtain.

Description

technical field [0001] The invention relates to a coating, in particular to a heat-insulating UHV flame-retardant coating and a preparation method thereof. Background technique [0002] Coatings are a mixture of polymer substances and ingredients, and can be coated on the surface of the substrate to form a new type of polymer material that adheres firmly and continuously. [0003] The main components of coatings are as follows: [0004] 1) Film-forming substance: It is the main component of the coating film, including oil, oil processed products, cellulose derivatives, natural resins and synthetic resins. Film-forming substances also include some non-volatile active diluents, which are the main substances that make the paint firmly adhere to the surface to be coated to form a continuous film, and are the basis of the paint and determine the basic characteristics of the paint; [0005] 2) Auxiliaries: such as defoamers, leveling agents, etc., and some special functional aux...

AI Technical Summary

Problems solved by technology

In the current industry, there are many types of insulating coatings. Because of the differences in coating formulations and processing techniques, the performance of insulating coatings is also uneven. Chinese patent number: CN103571329A discloses an insulating and anti-corrosion coating. The ceramic coating has organic Silicone resin, aluminum hydroxide, flame retardant, metal ceramic 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 relatively There are many metal oxides, and there is a risk of conductivity for long-term use, and the coating of this invention is brittle and easy to crack, and there are hidden dangers in long-term use

Notification number CN103045058B discloses a kind of insulating paint and electrical steel material and preparation method thereof, and this paint has water-soluble film-forming resin, coupling agent etc. and has better heat resistance, insulation, adhesion, corrosion resistance and Punching performance, although a coupling agent is used, but the coupling agent is not pre-treated, so that the overall performance of the insulating coating is not good enough
