Abstract

The invention discloses a sealing and positioning wax for an electronic tuner and a preparation method thereof. The sealing and positioning wax is prepared by mixing petroleum wax, polyethylene wax, paste hydrocarbon, and a butylene polymer according to specific proportion and processing. The sealing and positioning wax has the characteristics of high insulativity, moisture resistance, mobility, sealing performance, heat resistance, and cold resistance, appropriate physical and chemical property and using performance, non-toxicity, environmental-friendliness and the like. The sealing and positioning wax is suitable for sealing and positioning the electronic tuner.

Description

technical field [0001] The invention relates to a sealing and positioning wax, which is especially suitable for the sealing and positioning of electronic tuners. Background technique [0002] In the production process of electronic tuners, it is required to use sealing and positioning wax to seal tuner objects and position hollow coils to accurately adjust the inductance of the coils. The advantage of simply using ordinary paraffin or microcrystalline wax is that they are cheap. Due to the limitations of the inherent properties of microcrystalline wax, it is generally hard in the cured state. It is difficult to adjust the inductance of the coil, and brittle cracks may occur at low temperatures. , so that the inductance of the whole machine changes. Existing patents introduce that materials for sealing coils dedicated to electronic components use resin as the main component. For example, in the sealing methods introduced in US4115175 and US 5656350, resins are used to encaps...
