热固型改性聚苯板吸水率的研究

The research of water absorption for thermosetting modified polystyrene panel

本文从难燃液用量和可发性聚苯乙烯(EPS)颗粒与难燃液的配比两方面对影响热固型改性聚苯板的吸水率进行了研究。结果发现,EPS颗粒堆积密度相同时,吸水率随板材密度的提高而降低;相同密度的热固型改性聚苯板,随着EPS颗粒与难燃液配比的提高,吸水率先升高后降低。

In this paper, water absorption of thermosetting modified EPS panel has been researched from both the amount of fire retardant coating used and the ratio of EPS particle to fire retardant in it. The results show that the water absorption decreases as density of panel increases when packing density of EPS particle is the same. And the water absorption rate first rises and then decreases with the ratio of EPS particle to fire retardant coating increasing when the density of thermosetting modified polystyrene panel is kept the same.
