Aromatic corona-resistant high-thermal-conductivity insulation varnish for LED lamp holder and preparation method of aromatic corona-resistant high-thermal-conductivity insulation varnish for LED lamp holder

Abstract

The invention discloses aromatic corona-resistant high-thermal-conductivity insulation varnish for an LED lamp holder. The aromatic corona-resistant high-thermal-conductivity insulation varnish has the advantages that on the basis of the prior art, a heat dissipation enhancer prepared through modification is good in heat dissipation performance and is good in affinity with epoxy resin polymers so as to be less prone to sedimentation; coal ash subjected to coating modification by tea tree oil and orange peel extract is smooth and lubricant in surface, so that a varnish film is smoother without bubbling; after the modified nanometer titanium dioxide is added, a layer of 'shell' can be formed to protect an inner insulation material; nano particles with small particle size can be combined with an organic insulation resin material within a smaller range, so that electric strength of the varnish film is improved effectively, and excellent insulativity is achieved; the insulation varnish is scientific and reasonable in formula, simple and feasible in preparation method and capable of masking pungent smell of existing insulation varnish by aroma; the insulation varnish is highly resistant to corona while excellent high-temperature-resistant and insulating properties and increasing environment-friendly requirements are guaranteed.

Problems solved by technology

However, although the thermal conductivity of the insulating varnish increases significantly, the increase in electric strength is small and decreases with the increase of the powder content. The heat dissipation effect of spraying the insulating varnish on the LED lamp holder is not obvious, and it is easy to fall off during long-term use, making the metal material In a high-temperature environment, it is easy to oxidize with oxygen in the air, resulting in corrosion, so that the metal material gradually loses its strength and leads to structural loss, which becomes a hidden danger of various accidents. Therefore, it is necessary to improve the existing process and formula. To improve the physical and mechanical properties, UV resistance, high temperature resistance and corrosion resistance of insulating paint
