Abstract
The invention relates to an insulating coating material for electrical equipment, wherein the components comprise an epoxy resin, magnesium oxide, silicon nitride, alumina, linoleic acid, acrylic acid, diantimony trioxide, a toughening agent, an antifoaming agent, a leveling agent, and vinyl benzene. The insulating coating material prepared by using the formula of the present invention has characteristics of toughness, high thermal conductivity and good thermal stability of the metal, high temperature resistance, corrosion resistance and wear resistance of the ceramic, improvement of comprehensive performances of mechanical shock resistance and thermal shock resistance, good insulating property, excellent weather resistance, excellent aging resistance, good adhesion with a variety of metal substrates, high solid content, low volume shrinkage rate during drying curing, and simple, and convenient and rapid production, and can not be subjected to embrittlement cracking due to sudden cooling or heating.
Description
Technical field
The present invention relates to a kind of coating, particularly relate to a kind of insulation compound of power equipment.
Background technology
One deck insulating material is usually applied on the surface of the protector of power equipment or some equipment; as insulation compound, insullac etc.; power equipment external insulation can be improved like this; not only improve the security of power system; the reliability of system cloud gray model can also be improved, the thrifty cost of power equipment to a certain degree.
Now in the industry, insulation compound of a great variety, because the difference of the formula of coating and complete processing, so the various aspects of performance of insulation compound is also uneven.Traditional insulation compound often adopts chromic salt as component, and chromic salt toxicity is large, pollutes heavy, harmful effect is caused to human body and environment, the foreign technology that the electric steel insulating paint of many domestic well-known enterprises is introduced in one's early years also contains chromic salt, and this has caused the great attention of countries in the world.Present urgent need develops the insulation compound that a kind of applicable modern society uses, to meet the needs of countries in the world enterprise.
Summary of the invention
The object of the invention is, in order to overcome above defect, to provide a kind of insulation compound of power equipment.
The insulation compound of a kind of power equipment of the present invention, by massfraction ratio, epoxy resin 50-80 part, magnesium oxide 3-10 part, silicon nitride 8-15 part, aluminum oxide 1-5 part, linolic acid 2-7 part, vinylformic acid 1-6 part, antimonous oxide 5-15 part, toughner 3-6 part, defoamer 3-5 part, flow agent 4-6 part, vinyl benzene 4-8 part.
Described toughner is acetic ester.
Described defoamer is organic silicone defoamer.
Described flow agent is silicone based flow agent.
Beneficial effect of the present invention is: adopt the insulation compound that formula of the present invention is made, there is the toughness of metal, high thermal conductivity and good thermostability, there is again high temperature resistant, the corrosion-resistant and anti abrasive characteristic of pottery, can not because of quenching or shock heating and embrittlement, the mechanical resistant that improve coating is impacted and the over-all properties of heat shock resistance.Good insulating performance, weathering resistance, ageing resistance are excellent, and all have good sticking power to various metal base, solid content is high, and during dry solidification, volumetric shrinkage is low, make fast simple and convenient.
