为改善不饱和聚酯树脂(UPR)包覆层的耐烧蚀性能,在包覆层配方中引入有效阻燃剂包覆红磷.采用氧-乙炔烧蚀装置分别考察了包覆红磷与纳米Mg(OH)2、微米Mg(OH)2、Al(OH)3,三聚氰胺和硼酸锌复配填充UPR包覆材料的烧蚀性能.结果表明,包覆红磷与纳米Mg(OH)2复配时对UPR包覆层表现出较佳的耐烧蚀性能;当包覆红磷,纳米Mg(OH)2和UPR的质量比为30:20:100时,材料的线烧蚀率降至0.285mm/s,降低幅度为56%.用扫描电镜、热重分析仪对包覆红磷/纳米Mg(OH)2/UPR体系的耐烧蚀机理进行了分析.
為改善不飽和聚酯樹脂(UPR)包覆層的耐燒蝕性能,在包覆層配方中引入有效阻燃劑包覆紅燐.採用氧-乙炔燒蝕裝置分彆攷察瞭包覆紅燐與納米Mg(OH)2、微米Mg(OH)2、Al(OH)3,三聚氰胺和硼痠鋅複配填充UPR包覆材料的燒蝕性能.結果錶明,包覆紅燐與納米Mg(OH)2複配時對UPR包覆層錶現齣較佳的耐燒蝕性能;噹包覆紅燐,納米Mg(OH)2和UPR的質量比為30:20:100時,材料的線燒蝕率降至0.285mm/s,降低幅度為56%.用掃描電鏡、熱重分析儀對包覆紅燐/納米Mg(OH)2/UPR體繫的耐燒蝕機理進行瞭分析.

In order to improve the anti-ablation performance of unsaturated polyester(UPR) inhibitor, an effective flame retardant-eoated red phosphorus was added into the UPR inhibitor material. The anti-ablation eharacteristics of systems coated red phosphorus/nano-Mg(OH)2/UPR,red phosphorus/micro-Mg(OH)2/UPR,red phosphorus/Al(OH)3/UPR,red phosphorus/MA/UPR and red phosphorus/ZB/UPR was investigated by an oxy-acetylene ablation apparatus. The results show that the red phosphorus/nano-Mg(OH)2/UPR composite has the best antiablation performance. The linear ablation rate of red phosphorus/nano-Mg(OH)2/UPR system with mass ratio of 30 : 20 : 100 is 0. 285mm/s and decreases by 56% in comparison with UPR. The fire-retardant and anti-ablation mechanism of red phosphorus/Mg(OH)2/UPR system was analyzed by SEM and TGA.
