Sealing wax for electronic element coil

Abstract

The present invention relates to a kind of electronic element sealing wax composite comprising petroleum wax, polymer wax, tackifier and plasticizer. The sealing wax has the features of high droppingpoint, excellent high temperature performance, good plasticity and flexibility, excellent electric performance, powerful sealing force, short solidification time, no corrosion, no impurity, etc., andhas the sealing cost lower than available sealing material with resin as main component. The sealing wax is suitable for positioning and sealing electronic tuner, inductance coil and other electronicelement coil.

Description

1. Technical field

[0001] The invention relates to a wax composition, in particular to a sealing wax composition, especially a sealing wax composition suitable for positioning and sealing coils of electronic tuners and other electronic components. 2. Background technology

[0002] In the two processes of automatic waxing and manual waxing in the production process of electronic components such as electronic tuners, it is required to use sealing materials to fix the hollow coil to accurately adjust the inductance of the hollow coil. The advantage of simply using ordinary paraffin or microcrystalline wax is that they are cheap, but they have defects such as poor high-temperature performance and toughness and plasticity. change. The use of resin-based sealing compounds has the advantage of good high-temperature performance, but has defects such as poor toughness and plasticity and high cost, and cannot meet the current market competition requirements for low cost.
