摘要： Disclosed herein are a composition for producing flame-retardant expanded polystyrene foam and a method for producing flame-retardant beads using the same, in which a self-extinguishing flame-retardant composition is introduced into expanded polystyrene foam particles, such that self-extinguishing flame-retardant polystyrene foam of flame retardancy grade 3 can be produced. Specifically, the composition for producing flame-retardant expanded polystyrene foam is produced using a method comprising: a first mixing step (Sl) of mixing silicic acid, a surfactant and neozapon powder to obtain a first mixture (Pl); a second mixing step (S2) of adding the first mixture (Pl) and liquid glass to expandable polystyrene (EPS) as a raw material for producing expanded polystyrene foam to obtain a second mixture (P2); and a third mixing step (S3) of adding ammonium phosphate and a surfactant to the second mixture (P2) to obtain a third mixture (P3). The composition is pre-expanded by heating at about 90-120 ? to obtain beads having the flame-retardant material introduced therein. The beads can be compression-molded to obtain flame-retardant expanded polystyrene foam. The flame-retardant material in place of air is introduced into cells formed in the beads forming expanded polystyrene foam. Thus, when the polystyrene foam catches fire, it is melted, while flame-retardant gas is generated from the inside of the polystyrene foam to block oxygen, whereby the polystyrene foam shows flame retardant properties. In addition, it is possible to obtain flame-retardant polystyrene foam, which can be recycled without deteriorating thermal insulation, shock-absorbing and processability properties, which are the characteristic properties of polystyrene foam.
摘要翻译：本文公开了用于制造阻燃发泡聚苯乙烯泡沫的组合物和使用该组合物制造阻燃珠的方法，其中将自熄性阻燃组合物引入发泡聚苯乙烯泡沫颗粒中，使得自熄火焰可制造阻燃等级3的易碎聚苯乙烯泡沫。具体而言，制造阻燃发泡聚苯乙烯泡沫塑料用组合物是使用以下方法制造的：将硅酸，表面活性剂和新泽撒粉混合得到第一混合物（P1）的第一混合工序（S1）将第一混合物（P1）和液体玻璃作为生产发泡聚苯乙烯泡沫的原料的可发性聚苯乙烯（EPS）的第二混合步骤（S2）获得第二混合物（P2）; 和向第二混合物（P2）中加入磷酸铵和表面活性剂以获得第三混合物（P3）的第三混合步骤（S3）。组合物通过在约90-120℃加热预扩展以获得其中引入阻燃材料的珠粒。珠可以压缩成型以获得阻燃发泡聚苯乙烯泡沫。将代替空气的阻燃材料引入形成发泡聚苯乙烯泡沫的珠粒中形成的细胞中。因此，当聚苯乙烯泡沫体起火时，熔融，同时从聚苯乙烯泡沫内部产生阻燃气体以阻断氧，由此聚苯乙烯泡沫体显示阻燃性能。此外，可以获得阻燃聚苯乙烯泡沫，其可以再循环，而不会劣化绝热，减震和加工性能，这是聚苯乙烯泡沫的特征。
