(RU) ГРАНУЛЫ ПЕНОПОЛИСТИРОЛА С ФУНКЦИОНАЛЬНОЙ НАРУЖНОЙ ОБОЛОЧКОЙ, СПОСОБ ИХ ПОЛУЧЕНИЯ И ПРОДУКТ ФУНКЦИОНАЛЬНОГО ПЕНОПОЛИСТИРОЛА (EPS) И СПОСОБ ЕГО ПОЛУЧЕНИЯ С ИСПОЛЬЗОВАНИЕМ ТАКИХ ГРАНУЛ

Abstract

(EN)

Disclosed herein are expanded polystyrene particles having a polyvinyl acetate resin-based functional skin layer formed on the surface of expanded polystyrene particles. Further disclosed are a process for producing the expanded polystyrene particles and the use of the expanded polystyrene particles. According to the expanded polystyrene particles of the present invention, inherent properties of the expanded polystyrene, e.g., light weight, thermal insulation properties, shape stability, buffering properties and sound absorption, are ensured, and superior low-temperature bonding properties, air-tightness, waterproofness and durability are provided by the vinyl acetate based polymer constituting the skin layer. Optionally, various functional additives, including flame retardants, water repellents, antibacterial agents, colorants, flavoring agents, etc., can be added to the polyvinyl acetate resin to impart a variety of functions to the expanded polystyrene particles in a simple manner.

(RU)

Раскрываются гранулы пенополистирола, имеющие функциональную внешнюю оболочку, состоящую из смолы на основе поливинилацетата, образующуюся на поверхности гранулы пенополистирола. Дополнительно предлагается способ получения гранул пенополистирола и использование гранул пенополистирола. Благодаря гранулам пенополистирола настоящего изобретения обеспечиваются свойства, присущие гранулам пенополистирола, например легкость, термоизоляционные свойства, устойчивость формы, амортизационные свойства и звукопоглощение, а превосходная способность к связыванию при низких температурах, герметичность, водонепроницаемость и износостойкость обеспечиваются внешней оболочкой, состоящей из поливинилацетата. Необязательно, к смоле на основе поливинилацетата для придания различных функций гранулам пенополистирола, используя простые способы, могут быть добавлены различные функциональные добавки, включающие в себя огнезащитные составы, гидрофобные материалы, антибактериальные агенты, красители, ароматизаторы и т.д.
