摘要
通过在聚氨酯涂料中添加氢氧化铝[Al(OH)_3]、可膨胀石墨(EG)、三(2-氯异丙基)磷酸酯(TCPP),制备了兼具阻尼与阻燃性能的聚氨酯阻尼涂料。研究了3种阻燃剂对涂料力学性能、阻燃性能与阻尼性能的影响,研究结果表明:Al(OH)_3能提高材料的力学性能和阻燃性能,温度较低时,能提高阻尼性能,温度较高时,将降低阻尼性能;适量的EG能够显著提高材料阻燃性能与阻尼性能;TCPP可以提高材料的断裂伸长率,在添加量较少时,显著提高材料的阻燃性能,但材料阻尼性能有所降低。
Polyurethane damping coatings with both damping properties and flame retar- dancy are prepared by adding aluminum hydroxide [ A1 ( OH)3 ], expandable graphite (EG), tris (2-chloroisopropyl) phosphate (TCPP). The effects of the three kinds of flame retardants on the mechanical, flame retardancy and damping properties of the coatings are studied. The results showed that A1 (OH)3 can improve mechanical and flame retardant properties of the
