Description
Technical field
The present invention relates to a kind of preparation methods of P10 copper-clad plate prepreg.
Background technique
In recent years, a kind of resistance to ultra violet discoloration and the copper-clad plate (P10 that resistance to thermochromism is excellent, LED lamplight radiant output is high
Copper-clad plate), rapidly developed in LED (light emitting diode) application field.It has become meets particularity in copper-clad plate
A kind of product that can be required.
However, temperature raising can be such that transparent epoxy resin degree is decreased obviously, Barton research discovery temperature reaches 140 DEG C
When, epoxy resin is seriously degenerated, and LED light service life is influenced, and when temperature reaches 150 DEG C, transparent epoxy resin degree is decreased obviously,
So as to cause LED lamplight radiant output decrease.
Presently, it generallys use plus appropriate inorganic filler reduces copper-clad plate thermal expansion coefficient.Copper foil, glass-fiber-fabric, resin
Three's thermal expansion coefficient difference is larger, and appropriate filler, which is added, can be relieved the difference of expanding with heat and contract with cold of three, in this way can be to avoid high temperature
Lower three deforms different caused route deformation fracture, to avoid causing catastrophic to fail.But P10 copper-clad plate is come
It says, its production cost is still higher at present, and the resin transparent degree decline under high temperature still has, service life and resistance to ultraviolet
