METHOD FOR MANUFACTURING HOLLOW SILICA PARTICLES, HOLLOW SILICA PARTICLES, AND COMPOSITION AND THERMAL INSULATION SHEET COMPRISING SAME |
摘要 |
Provided are hollow silica particles that have a refractive index of 1.2-1.4, a thermal conductivity of less than 0.1 W/m·K, an oil absorption rate of 0.1 ml/g or below, a porosity of at least 90% when mixed with a resin, and a particle distribution coefficient of variation (CV value) of 10% or below. Further provided are a composition comprising the hollow silica particles, and a transparent thermal insulation sheet which has a visible light transmittance of at least 70%, a thermal conductivity of less than 0.1 W/m·K, and a filling rate of particles of 30-80%. |
