Embodiment Construction

[0013] An aging-resistant insulating paper for transformers, prepared from the following raw materials in parts by weight (kg): nano-diatomite 10, nano-titanium dioxide 3, phenolic resin 2, pulp board 500, sodium silicate 1.3, carboxymethyl cellulose Sodium 1, aluminum hydroxide 2.2, titanium nitride 2, morpholine 0.3, ceramic fiber 3.3, melamine 1.3, appropriate amount of deionization.

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

[0015] (1) Dry diatomaceous earth in an oven at 100°C for 30 minutes, add nano-titanium dioxide to 0.5Wt% silane coupling agent kh550 absolute ethanol solution after cooling, then add titanium nitride for reflux condensation treatment, take out Drying and milling for later use;

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

Abstract

The invention discloses aging-resistant insulation paper for a transformer. The insulation paper is prepared from the following raw materials in parts by weight: 10-13 parts of nano diatomite, 3-5 parts of nano-titanium dioxide, 2-3 parts of phenolic resin, 500-550 parts of pulp boards, 1.3-1.5 parts of sodium silicate, 1-1.3 parts of sodium carboxymethylcellulose, 2.2-2.4 parts of aluminum hydroxide, 2-3 parts of titanium nitride, 0.3-0.5 part of morpholine, 3.3-3.6 parts of ceramic fiber, 1.3-1.6 parts of melamine, and a proper amount of deionized water. The preparation method provided by the invention is simple and low in cost, overcomes the defects that the traditional insulation paper is difficult to bear great pressure and is liable to tear and age, and has good practical prospect.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to aging-resistant insulating paper for 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 required ...
