Insulating paint is usually composed of three parts: paint base, solvent or diluent and auxiliary material. According to the scope of use and morphology, it can be divided into four kinds: impregnating varnish, covering paint, silicon steel sheet paint and corona proof paint.

Self drying insulating paint refers to an insulating paint which can be dried into film after coating. The mechanism of self drying is generally divided into three categories: one is volatile drying, that is, the high molecular weight solid resin dissolves in the appropriate solvent, the solvent evaporated after the coating, leaving the solid film-forming resin. This kind of insulating paint is easy to apply and quick to dry. But the solvent resistance is poor, and the heat is easy to soften. The second type is oxidation drying. This kind of insulating varnish contains dry vegetable oil, and unsaturated double bond in the molecular structure of dry vegetable oil will oxidize chain by itself under the action of oxygen in air, so as to achieve the purpose of drying. General oily, phenolic resin and drying alkyd resin insulating paint are oxidation drying insulation paint. Because of the high content of vegetable oil and low heat resistance, this kind of insulating varnish is grade A and class E insulating material. The drying time is long, usually one day. The third type is curing and drying at normal temperature, and this kind of insulating paint is cured at room temperature and by chemical reaction. This kind of paint is double or multi component. This kind of paint is commonly used, such as polyamide resin curing epoxy paint and two-component polyurethane paint, etc.. This kind of paint is a chemical chain, and it has good heat resistance, solvent resistance and chemical resistance. Insulating paint, varnish (commonly known as: self baking, dry, non solvent type) insulation paint is a polymer polymer based ZS-1091 high-temperature ceramic insulation coatings, the coating is divided into temperature below 600 DEG C water solvent and 600-1700 two. The coating can be coated surface to form a layer with higher volume resistivity, can withstand the strong electric field without ceramic coating breakdown, the coating has high mechanical strength and good chemical stability, water resistance, aging resistance, chemical corrosion resistance, and is also resistant to mechanical shock and thermal shock properties of the coatings can be. Continuous work in the corresponding working temperature under. The most fundamental thing is to rely on a strong technical innovation ability, make full use of chemistry and chemical engineering, the latest scientific and technological achievements, which include the following: 1: strictly control the ratio of raw materials in the production process, to avoid stray ions, especially alkali metal or alkaline earth metal ions are introduced. (2) reduce the content of glass phase as much as possible, and reduce the conductivity of glass phase added to improve the process performance. Third:: strictly control the introduction of iron, cobalt and other polyvalent metal ions, in order to avoid free ions and holes. At the same time, the temperature and atmosphere in the production process should be strictly controlled so as to avoid oxidation and reduction reaction to produce electrons and holes, and to prevent lattice transformation from crystal defects. The product has been widely used in high temperature electric furnace, induction furnace, high temperature motor, refractory device, motor, telecommunications equipment, high temperature equipment and other upper insulation. An important insulating material which can be solidified into an insulating film or an insulating whole under certain conditions. It is generally composed of three parts: paint base, solvent or diluent, and auxiliary material.
