【発明の名称】シリカ質複合微粒子
Document Type and Number:
Japanese Patent JP2676849
Kind Code:
B2
Abstract:
PURPOSE:To improve resistance to external environment, such as heat, by making true spherical siliceous particles stick onto the surface of a thermoplastic resin having a specific particle diameter. CONSTITUTION:Parent particles consisting of a thermoplastic resin (e.g., PE) having 1-500mum particle diameter are mechanically mixed with true spherical siliceous particles having 0.1-50mum particle diameter as son particles at 8:>=1 particle diameter ratio of the parent to the son particles so that the son particles may stick to the surfaces of the parent particles.
