Abstract:
본 발명의 복합시트는 매트릭스 및 상기 매트릭스에 함침된 보강재를 포함하며, 상기 매트릭스는 제1 이액형 폴리오가노실록산과 제2 이액형 폴리오가노실록산을 포함하는 것을 특징으로 한다. 상기 매트릭스는 가교된 실리콘 고무(silicone rubber)의 구조를 가지므로, 유리전이온도(Tg)에 구애받지 않고 고온에서 사용할 수 있으며, 많이 구부려도 백화현상이 오거나 부러지지 않고, 높은 내굴곡성 특성을 제공할 수 있다.
Abstract:
The present invention relates to a composite sheet including reinforcing material impregnated in a matrix of the sheet, cyclic siloxanes, and polysiloxane reactants comprising a linear terminal vinyl group. The composite sheet suppresses ring strain deformation and pyrolysis under the environment of temperatures higher than 350°C, reducing defects of the material resulting in a high temperature process when producing substrates.
Abstract:
PURPOSE: A substrate for a display device is provided to reduce flatness and moisture permeability and to improve flex resistance, flexibility, and durability. CONSTITUTION: A substrate for a display device comprises a matrix(2), a reinforcing agent(1) impregnated in a matrix, a coating layer formed on at least one side of the matrix, and a barrier layer(4) formed on one side of the coating layer. If the elastic modulus of the matrix is E2 at 25°C and the elastic modulus of the coating layer is E3 at 25°C, E3/E2 is 5 x 10^4 or less. The coating layer has a gradient elastic modulus structure. The elastic modulus of the matrix at 25°C is 0.1GPa or less. The elastic modulus of the coating layer is 0.1GP-10GPa. The elastic modulus of the barrier layer is 10GPa or more. The coating layer comprises one or more selected from an acrylic-based resin, epoxy-based resin, silicon-based resin, urethane-based resin, and unsaturated polyester-based resin.
