Embodiment Construction

[0013] An insulating paper for high wear-resistant transformers, prepared from the following raw materials in parts by weight (kg): nano-titanium dioxide 10, nano-silicon dioxide 3, phenolic resin 2, pulp board 500, sodium carboxymethyl cellulose 1, Mongolian Destonening 2.4, polypropylene fiber 4.5, trihydroxypolyether 0.5, 1,3 dimethylimidazolinone 0.3, calcium molybdate 1.2, deionized water in proper amount.

[0014] The insulating paper for a high wear-resistant transformer is prepared by the following specific steps:

[0015] (1) Dry nano-titanium dioxide and nano-silicon dioxide in an oven at 100°C for 30 minutes, add them to 0.5Wt% silane coupling agent kh550 absolute ethanol solution after cooling, and then reflux and condense the solution. Dried and milled for use;

[0016] (2) Mix the phenolic resin with a solid content of 15% and the product prepared in step (1) evenly, and then heat to 80°C and stir for 0.5h to react, then add polypropylene fiber to soak for 4h at...

Abstract

The invention discloses a high-wear-resistant transformer insulation paper, which is prepared from the following raw materials by weight part: 10-13 of nano-titanium dioxide, 3-4 of nano-silica, 2-3 of phenolic resin, 500-550 of a pulp board, 1-1.3 of sodium carboxymethyl cellulose, 2.4-2.6 of montmorillonite, 4.5-5 of polypropylene fiber, 0.5-0.7 of trihydroxy polyether, 0.3-0.5 of 1, 3-dimethyl-2-imidazolinone, 1.2-1.5 of calcium molybdate and a proper amount of deionized water. The insulation paper provided by the invention has the characteristics of simple preparation method, good insulation effect, simple operation, excellent wear-resistant, moisture-proof, sterilization and other effects, and is worth popularizing.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to insulating paper for high wear-resistant transformers. Background technique [0002] Insulating paper is widely used as insulating material for equipment such as motors, cables, capacitors and transformers, and is also the main component material of insulating materials such as laminated products, composite materials and prepreg materials. Due to the special use of insulating paper, it is required to have some characteristics different from other paper types, mainly including mechanical properties, electrical properties and thermal stability. Moreover, due to the different environments in which various types of electrical equipment are used, such as motors operating under hot and humid conditions, motors in chemical plants that are often exposed to high concentrations of corrosive chemical media, and motors operating under radioactive radiation, the insulating paper is requi...
