ABSTRACT

Toxic liquid tris (1-chloro-2-propyl) phosphate) (TCPP) was microencapsulated with the melamine-formaldehyde resin in water and added as the fire-retardant into the polyurethane foam to slow down its diffusion out. The effect of sodium dodecyl benzenesulfonate and polyvinyl alcohol contents on the particle size was studied and the average size of about 50–250 μm was produced. Increasing the stirring rate and PVA content decreased the diameter of the microcapsule. The cell size of polyurethane foams containing TCPP microcapsules was in the range of 100–600 μm. The polyurethane foam containing 9 wt% of the TCPP microcapsules was HB grade flame-rated.

磷酸三(1-氯-2-丙基)磷酸酯(TCPP)微胶囊,用于制备阻燃硬质聚氨酯泡沫

摘要

用三聚氰胺-甲醛树脂将有毒的液态三(1-氯-2-丙基)磷酸酯(TCPP)微囊化在水中,并作为阻燃剂添加到聚氨酯泡沫中,以减缓其扩散。研究了十二烷基苯磺酸钠和聚乙烯醇含量对粒径的影响,平均粒径约为50-250μm。增加搅拌速率和PVA含量减小了微胶囊的直径。含有TCPP微胶囊的聚氨酯泡沫的泡孔尺寸在100-600μm的范围内。含有9 wt%的TCPP微胶囊的聚氨酯泡沫为HB级阻燃等级。
