Embodiment Construction

[0013] An insulating paper for transformers with long service life, prepared from the following raw materials in parts by weight (kg): titanium oxide fiber 12, nano-titanium dioxide 3, phenolic resin 2, pulp board 500, triglycerol monostearate 0.1 , styrene-butadiene latex 2, wood fiber 4.6, sodium alginate 1.5, distearyl thiodipropionate 0.4, white carbon black 0.5, appropriate amount of deionized water.

[0014] The insulating paper for a transformer with a long service life is prepared by the following specific steps:

[0015] (1) Dry nano-titanium dioxide in an oven at 100°C for 30 minutes, add titanium oxide fibers to 0.5Wt% silane coupling agent kh550 absolute ethanol solution after cooling, and then reflux the solution for condensation treatment, take it out and bake dry milling 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, then add wood fiber to soak for 4h...

Abstract

The invention discloses an insulation paper with long service lifetime for a transformer. The insulation paper is prepared from the following raw materials in parts by weight: 12-15 parts of a titanium dioxide fiber, 3-4 parts of nanometer titania, 2-3 parts of phenolic resin, 500-550 parts of a pulp board, 0.1-0.3 part of tripolyglycerol monostearates, 2-2.6 parts of styrene-butadiene latex, 4.6-5 parts of a wood fiber, 1.5-2 parts of sodium alginate, 0.4-0.6 part of distearyl thiodipropionate, 0.5-0.7 part of white carbon black and a proper amount of deionized water. The prepared insulation paper is sufficient in raw material, simple in production technology, not easy to combust, easy to store, long in service lifetime and worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to insulating paper for transformers with long service life. 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 re...
