EXPANDED ARTICLES USING DIFFERENT TYPES OF EXPANDED PARTICLES AND PROCESS FOR PRODUCING THE SAME

摘要

The present invention relates to a uniform composite foaming molded article using different kinds of foamed particle, and to a production method thereof. according to the present invention, in terms of the composite foaming molded article formed by fusion of two or more different kinds of foamed particles, in the composite foaming molded article, uniformly mixed are a secondary foamed particle of high density preliminary foamed particle which is relatively has large density while being in a preliminary foamed particle form, and a secondary foamed particle of a coated low density preliminary foamed particle on which a coating layer capable of increasing density is formed on a surface of the low density preliminary particle which is relatively low in density when being in the preliminary foamed particle form. Provided is the uniform composite foamed molded article using different kinds of foamed particles.
