Title
(EN) FOAMED POLYSTYRENE BEAD HAVING FUNCTIONAL SKIN LAYER AND PROCESS FOR PREPARATION THEREOF, FUNCTIONAL FOAMING POLYSTYRENE PRODUCT AND PROCESS FOR PREPARATION THEREOF
(KO) 기능성 스킨층을 갖는 발포 폴리스티렌 입자와 그제조방법, 및 이를 이용한 기능성 발포 폴리스티렌성형물과 그 제조방법
Abstract
(EN)

PURPOSE: Provided are a foamed polystyrene bead having functional skin layer process with various functions such as flame-retardancy, anti-bacterial or coloring properties by coating surface of polystyrene particles with functional coating agent composition.

CONSTITUTION: The foamed polystyrene particle comprises functional skin layer consisting of functional coating material including 10-99.9 wt.% of vinyl acetate resin and 90-0.1 wt.% of functional additive on the surface of the foamed polystyrene particle obtained by heating and foaming polystyrene bead or pellet. The functional skin layer has thickness in 0.003-10% of overall particle size and 1-95 wt.%. The process comprises the steps of foamed polystyrene particle; coating functional coating composition over surface of the foamed polystyrene particle; and releasing individual particles by adding a releasing agent to the particle.
