METHOD FOR PREPARING POLYOLEFIN FOAMED PARTICLES HAVING EXCELLENT FORMABILITY |
摘要 |
A method for preparing a polyolefin-based foamed particle is provided to improve the moldability of a polyolefin-based foamed particle and to reduce the cost for treating wasted water by reusing a dispersion medium. A method for preparing a polyolefin-based foamed particle comprises the steps of dispersing linoleic acid, a vegetable oil containing linoleic acid or an organic compound containing a fatty acid of lecithin in a dispersion medium; injecting a polyolefin-based resin particle and a foaming agent to the obtained one and increasing the temperature to prepare a polyolefin-based foamed particle; withdrawing a dispersion medium from the prepared polyolefin-based foamed particle to obtain a polyolefin-based foamed particle; and reusing the withdrawn dispersion medium to the preparation step of the polyolefin-based foamed particle.
