Abstract

The invention relates to an insulating potting wax composition, comprising 72%-88% of petroleum wax, 1%-6% of Fischer-Tropsch wax, 1%-20% of tackifier, and 1%-20% of vaseline . The insulating potting wax composition of the present invention has the characteristics of excellent high-temperature performance and anti-corrosion performance, excellent electrical performance, good moisture resistance and the like. The insulating potting wax composition is not only suitable for insulating impregnation potting of electronic transformers and high-frequency transformers, but also suitable for insulating dipping potting of inductance coils and other special coils of electronic components.

Description

technical field [0001] The invention relates to an insulating potting wax composition, in particular to an insulating potting wax composition used for electronic transformers and high-frequency transformers. Background technique [0002] In the production of transformers, it is often necessary to use an insulating potting wax composition to impregnate and pot the transformer to improve the insulation performance of the transformer. In the prior art, commercial paraffin or microcrystalline wax is simply used. Although the price is cheap, there are defects such as poor high-temperature performance and toughness and plasticity. Potting transformers with oil is prone to leakage. The use of resin materials can make the transformer have good high temperature resistance, but it has defects such as poor toughness and plasticity and high production cost, which cannot meet the requirements of current manufacturers. [0003] In the prior art, for example, a waxy composition is disclo...
