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.
(ZH) 本发明公开了一种发泡聚苯乙烯颗粒，其具有在发泡聚苯乙烯颗粒表面上形成的乙酸乙烯酯树脂基功能表层。进一步公开了生产发泡聚苯乙烯颗粒的方法以及发泡聚苯乙烯颗粒的用途。根据本发明的发泡聚苯乙烯颗粒，确保了发泡聚苯乙烯固有的性能，例如轻的重量、绝热性能、形状稳定性、缓冲性能和吸声，并通过构成表层的乙酸乙烯酯基聚合物来提供优异的低温粘结性能、气密性、防水和耐用性。任选地，各种功能添加剂，其中包括阻燃剂、防水剂、抗菌剂、着色剂、增味剂等可加入到乙酸乙烯酯树脂中，以简单的方式赋予发泡聚苯乙烯颗粒各种功能。
