Problems solved by technology

[0007] However, the fiber-reinforced composite material in JP-A-2005-60680 does not consider use as a sealant, adhesive or filler.
[0008] In addition, the thermal conductivity in the in-plane direction (board surface direction) of this fiber-reinforced composite material shows a high thermal conductivity of, for example, 1 W / m·K, but the thermal conductivity in the direction perpendicular to it has not been clarified.

Embodiment 1

[0193] Example 1: Fiber-reinforced composite resin composition containing BC

[0194] First, add the culture solution to the strain of acetic acid bacteria (FF-88) in the freeze-dried state, and let it stand for 1 week (25-30°C). Among the bacterial cellulose produced on the surface of the culture solution, select the one with a thicker thickness. Bacterial cellulose, take a small amount of the culture solution of the strain and add it to the new culture solution. Then, this culture solution was placed in a large incubator, and static culture was performed at 25 to 30° C. for 7 to 30 days. As a culture solution, 2% by weight of glucose, 0.5% by weight of yeast extract for bacteria, 0.5% by weight of peptone for bacteria, 0.27% by weight of disodium hydrogen phosphate, 0.115% by weight of citric acid, and 0.1% by weight of magnesium sulfate heptahydrate were used. Hydrochloric acid to adjust pH to 5.0 aqueous solution (SH medium).

[0195]The thus-produced aqueous bacterial c...

Embodiment 2

[0198] Example 2: Fiber-reinforced composite resin composition containing Nano MFC from pulp

[0199] In addition to fully stirring microfibrillated cellulose in water: MFC (processed by a high-pressure homogenizer to microfibrillate coniferous kraft pulp (NBKP) with an average fiber diameter of 1 μm), prepare 7 kg of 1 wt % concentration Except for the aqueous suspension, in the same manner as in Example 1, the epoxy resin was impregnated to manufacture the fiber-reinforced composite resin composition of the present invention in which the Nano MFCs were randomly oriented. For the fiber-reinforced composite resin composition and curing The product was evaluated in the same manner as in Example 1, and the results are shown in Table 1.

Embodiment 3

[0200] Example 3: Fiber Reinforced Composite Resin Composition Containing NanoMFC from Cotton

[0201] Cotton (absorbent cotton) was used instead of pulp, and epoxy resin was impregnated in the same manner as in Example 1 to manufacture a fiber-reinforced composite resin composition of the present invention in which Nano MFCs were randomly oriented in the composition. For this fiber-reinforced composite resin composition The product and the cured product were evaluated in the same manner as in Example 1, and the results are shown in Table 1.

Abstract

Disclosed is a fiber-reinforced composite resin composition which can be used as a sealing agent, an adhesive or a filler, specifically a fiber-reinforced composite resin composition which has low thermal expansion, high strength light weight and high thermal conductivity at such levels that have been required recently, particularly which has a high isotropic thermal conductivity at a satisfactory level. The composition comprises a fiber having an average fiber diameter of 4 to 200 nm. When the composition is cured in a plate-like shape, the cured product has a total light transmittance of 70% or higher per 50 [mu]m thickness as measured at an wavelength of 400 to 700 nm and thermal conductivities both in a thickness-wise direction and a plane-wise direction of 0.4 W / m. K or higher. In the cured product, the fiber is oriented randomly.

Description

technical field [0001] The present invention relates to a fiber-reinforced composite resin composition used as a sealant, an adhesive, or a filler. Specifically, it relates to a highly transparent sealant, adhesive, or A fiber-reinforced composite resin composition for a filler. The present invention also relates to adhesives and sealants formed using the fiber-reinforced composite resin composition. Background technique [0002] Resin compositions used as sealants, adhesives, and fillers may require high transparency, low thermal expansion, high strength, light weight, and high thermal conductivity due to their use and characteristics of cured products. Wait. For example, sealing materials for LEDs are required to be highly transparent to transmit light from phosphors, and to ensure dimensional stability, durability, and light weight of products in the use environment, small thermal expansion coefficients and high strength are required. and lightweight. Furthermore, wit...
