Silicone resin reflective substrate, manufacturing method for same, and base material composition used in reflective substrate
First Claim
1. A silicone resin reflective substrate comprising:
- a reflective layer containinga white inorganic filler powder including titanium oxide surface-treated with Al, Al2O3, ZnO, ZrO2, SiO2 and/or silane coupling agent dispersed in a three-dimensionally cross-linked silicone resin,the reflective layer being made from a liquid-like base material composition, or a grease-like, a plastic-like or a millable-type base material composition having a plasticity to be cured for the reflective layer so that the white inorganic filler powder is incorporated into a 3-dimensionally cross-linked silicone resin, containing;
a polymerizable silicone resin,the white inorganic filler powder including titanium oxide surface-treated with Al, Al2O3, ZnO, ZrO2, SiO2 and/or silane coupling agent, which has a higher refractive index than that of the three-dimensionally cross-linked silicone resin and is dispersed in the base material composition,an adhesive component of a silane compound or siloxane compound having a reactive functional group, anda reaction inhibitor;
the reflective layer being bonded to a support body as a film-like shape, 3-dimensional-like shape or plate-like shape; and
the silicone resin reflective substrate maintaining reflectance of a level of 85% or more at a region of 450 to 1000 nm and a level of 90% or more at a region of 450 nm by the reflective layer.

Abstract
A versatile silicone resin reflective substrate which exhibits high reflectance of high luminance light from an LED light source over a wide wavelength from short wavelengths of approximately 340-500 nm, which include wavelengths from 380-400 nm near lower limit of the visible region, to longer wavelength in the infra-red region. The silicone resin reflective substrate has a reflective layer which contains a white inorganic filler powder dispersed in a three-dimensional cross linked silicone resin, the inorganic filler powder having a high reflective index than the silicone resin. The reflective layer is formed on a support body as a film, a solid, or a sheet. The silicone resin reflective substrate can be easily formed as a wiring substrate, a packaging case or the like, and can be manufactured at low cost and a high rate of production.
