Embodiment 1

[0075] E-glass glass cloth (thickness 50 μm, refractive index 1.560, manufactured by Unitika cloth, E06B (#1080) is burned to remove organic matter, and then treated with acryloxypropyltriethoxysilane (alkylsilane) The resin composition (refractive index 1.560 after the cross-linking) that is made of following compound is impregnated on this glass cloth and degasses. Said compound is bicyclic dienyl diacrylate (formula 1) (Toagosei Co., Ltd. ), M-203, cross-linked refractive index 1.527) 58 parts by weight, bis[4-(acryloyloxyethoxy)phenyl] sulfide (Formula 3) (Toagosei Co., Ltd. trial product, TO-2066, crosslinked refractive index 1.606) 42 parts by weight, and photopolymerization initiator (1-hydroxy-cyclohexyl-phenyl-ketone (manufactured by Ciba Specialty Chemicals, Irgacure 184) 0.5 parts by weight. The obtained glass cloth Laminated with resin / glass cloth / resin / glass cloth / resin, sandwiched between glass plates that have been released from the mold, and irradiated at about...

Embodiment 2

[0077] Prepare 53 parts by weight of norbornane dimethylol diacrylate (formula 2) (Toya Gosei Co., Ltd. trial product, refractive index after crosslinking: 1.520), bis[4-(acryloyloxyethoxy)benzene base] sulfide (Formula 3) (Toagosei Co., Ltd. trial product, TO-2066, after crosslinking, the refractive index is 1.606) 47 parts by weight, and a resin composition composed of 0.5 parts by weight of photopolymerization initiator (refractive index after crosslinking Rate 1.560) as a resin composition, it was impregnated on the same glass cloth as in Example 1 and defoamed. This glass cloth was laminated in the same manner as in Example 1, and then irradiated with ultraviolet light and heat-treated to obtain a sheet-shaped plastic substrate (thickness: 0.2 mm). The glass filler content of the substrate was 30% by weight.

Embodiment 3

[0079] Burn E-glass glass cloth (thickness 100 μm, refractive index 1.560, manufactured by Unitika cloth, E10A (#2117) to remove organic matter, and then treat it with acryloxypropyltriethoxysilane (alkylsilane) On this glass cloth, impregnate the resin composition of the same composition as embodiment 1 and carry out defoaming.This glass cloth is clamped on the glass plate through release process, irradiates about 500mJ / cm from both sides 2 UV light cures it. After heating in a vacuum oven at about 100° C. for 3 hours, and then heating at about 250° C. for 3 hours, a thin plastic substrate with a thickness of 0.1 mm was obtained. The glass filler content of the substrate was 50% by weight.

Abstract

The present invention provides a transparent composite material composition, which has a small coefficient of linear expansion and excellent transparency, heat resistance, and solvent resistance, and can be used as an optical sheet for liquid crystal display elements or organic EL display elements, and can replace glass. The transparent composite material composition is a transparent resin composite material composed of a transparent resin (a) and a glass filler (b), and the transparent resin (a) is one or more of a material whose refractive index after crosslinking is lower than that of the glass filler (b). A copolymer composed of one or more reactive monomers and one or more reactive monomers higher than the glass filler (b).

Description

technical field [0001] The invention relates to a transparent composite material composition which has a small linear expansion coefficient, excellent transparency, heat resistance and solvent resistance, and can replace glass. This transparent composite material composition is suitable for use as, for example, optical sheets such as liquid crystal display substrates, organic EL display element substrates, color filter substrates, touch panel substrates, solar cell substrates, transparent plates, optical lenses, optical elements, Optical waveguide, LED packaging materials, etc. Background technique [0002] In general, glass plates are widely used as display element substrates for liquid crystal display elements such as active matrix type or organic EL display elements, color filter substrates, substrates for solar cells, and the like. However, since glass plates are fragile, cannot be bent, have a large specific weight, cannot reduce weight, etc., in recent years, plastic ...
