Problems solved by technology
[0003] In the production of capacitors, the main dielectric and the pores between the plates and the main dielectric are usually filled with paraffin or microcrystalline wax to improve the capacitance, insulation, and heat resistance. However, only paraffin or microcrystalline wax is used for potting. Poor toughness and plasticity, easy to be brittle at low temperature and other defects, not suitable for the current diversified market requirements

Abstract
The invention discloses a capacitor encapsulation wax. The capacitor encapsulation wax is prepared from, by weight, 2-4 parts of sebacic acid, 1-3 parts of decanediamine, 4-6 parts of pentaerythritol,10-12 parts of bisphenol A, 80-140 parts of petroleum wax, 12-14 parts of polyethylene wax, 10-30 parts of beeswax, 3-5 parts of straw ash, 3-4 parts of attapulgite, 4-7 parts of methyl cellulose, 2-6 parts of chlorinated paraffin, 1-3 part of fatty acids and 3-5 parts of pentaerythritol. The finally prepared encapsulation wax can significantly improve the low-temperature cracking performance ofpetroleum wax, has excellent electrical properties and appropriate kinematic viscosity, and is convenient for filling metalized film capacitor gaps.
Description
technical field [0001] The invention relates to the field of organic polymer compounds, in particular to a capacitor potting wax. Background technique [0002] With the rapid development of electronic information technology, the upgrading speed of digital electronic products is getting faster and faster. The production and sales of consumer electronic products, mainly flat-panel TVs (LCD and PDP), notebook computers, digital cameras and other products, continue to grow. Capacitor industry growth. Two conductors close to each other, sandwiching a layer of non-conductive insulating medium, constitute a capacitor. A capacitor stores charge when a voltage is applied between its two plates. The capacitance of a capacitor is numerically equal to the ratio of the amount of charge on a conductive plate to the voltage between the two plates. The basic unit of capacitance of a capacitor is farad (F). Capacitive elements are usually represented by the letter C in circuit diagrams. ...
