Description
Technical field
The invention belongs to a kind of coating, specifically, more particularly to a kind of heat-conductive coating.
Background technology
Nowadays various electrical equipment, many heat generating components are electronically or mechanically included in equipment, for example lighting transistor, CPU, battery and
Motor etc., and with advances in technology, in constantly reduction, power is also constantly increasing the volume of these components.But in power
While increase, its heat consumption is also accordingly being significantly increased.If substantial amounts of heat consumption can not be distributed in time, will greatly influence
The reliability of equipment.However as continuing to increase for amount of filler, thermal conductivity gradually rises, and mechanical property but constantly declines.It is existing
Have in technology and also lack a kind of indices and meet the excellent High Performance Insulation coating of requirements at the higher level particularly heat conductivility.
The content of the invention
Excellent heat conductivility, resistance to elevated temperatures, corrosion resistance, fire resistance are provided simultaneously with it is an object of the present invention to provide a kind of
High-performance heat-conductive coating, to overcome drawbacks described above of the prior art.
The present invention is realized using following technical scheme：
A kind of heat-conductive coating, including following weight ratio ingredient：Epoxy modified silicone resin 30-50 parts, curing agent 8-15 parts,
Silicon nitride 25-35 parts, aluminum oxide 5-10 parts, fire retardant 3-7 parts, titanate coupling agent 2-5 parts, preservative 2-5 parts,
Solvent 45-60 parts.
The curing agent is low molecular polyamides.
The solvent is dimethylbenzene and acetone according to 1:2 ratio is mixed.
Compared with prior art, the beneficial effects of the invention are as follows：
(1) epoxy modified silicone resin of the present invention has good, good manufacturability of high temperature resistant, strong mechanical performance and electrical insulating property etc.
Feature, adds insulating heat-conductive inorganic filler to prepare heat conductive insulating high-temperature resistant coating.
(2) using silicon nitride and aluminum oxide composition mixed fillers in the present invention, aluminum oxide accounts for the consumption of total filler consumption 20% or so,
System can be made to obtain highest thermal conductivity under this consumption, be may also reach up reduces cost, improved the purpose of mechanical property.
(3) heat conducting coating of the present invention can at 200 DEG C long-term use, fully meet H grades of heat resistant requirements of electric insulation occasion.
