Abstract

PURPOSE:To improve the heat insulating properties by making white powdery child particles of Al(OH)3 adhere to the surface of a parent particle composed of a fine hollow powder, dispersing the resultant hollow capsule powder as a filler in a resin matrix, molding and hardening it. CONSTITUTION:A fine hollow powder such as an organic microballoon having several score to several hundred mum average particle diameter is used as a parent particle and child particles composed of a white Al(OH)3 powder having several mum average particle diameter are made to adhere to the surface of the parent particle according to the microcapsulation method such as the electrostatic adhesion method so as to prepare a hollow capsule powder. The resultant hollow capsule powder is then used as a filler and mixed in a matrix composed of a liquid methacrylate resin, etc., in a prescribed ratio. The resultant mixture is stirred and uniformly dispersed so as to prepare a raw material of a faking material. The resultant raw material is subsequently molded according to the press molding method or the injection molding method, then cooled and hardened, thus producing the objective prescribed-shape faking material excellent in heat insulating properties, e.g. an artificial marble, an artificial ivory or an artificial wood.

This microballoon is made of organic and inorganic materials, and typical ones include glass balloons, silica balloons, silas balloons, carbon balloons, phenol balloons, vinylidene chloride balloons, alumina balloons, zirconia balloons, etc. Among these, phenolic balloons and vinylidene chloride balloons, which are organic microballoons, are suitable for use in the invention. That is, since inorganic microballoons such as glass balloons and silica balloons have poor elasticity, they may be cracked by impact or the like during encapsulation. Further, the size of the microballoons used is preferably in the range of several tens to several hundreds of μm due to reasons such as encapsulation.
If the thickness is several tens of μm or less, it is necessary to use a large amount of microballoons in order to obtain desired weight reduction and heat insulation properties.
This is because if the thickness is several hundreds μm or more, the strength and quality may be deteriorated.
