所述的聚脲高分子复合防腐材料层,在喷涂聚脲层前,在树脂混合物组分中加入达到阻燃效果的有机阻燃剂(溴系、磷氮系、氮系和红磷及化合物)或无机阻燃剂(三氧化二锑、氢氧化镁、氢氧化铝,硅系等)。
加入有机阻燃剂的占比为5%-10%,无机阻燃剂的占比为15-20%,酒精喷灯火焰燃烧试验;
有焰燃烧:当酒精喷灯移走后,每组6条试件的有焰燃烧时间算术平均值低于5s,其中最大单值不大于15s;
无焰燃烧:当酒精喷灯移走后,每组6条试件的无焰燃烧时间算术平均值低于20s,其中最大单值不大于60s。
所述的电缆挂钩为单件标准间,防脱槽设计,自重闭锁,挂钩为钢板冲压后弯折成型,防脱槽加工后焊接成型;可根据需要任意组合。
本发明与现有技术相比具有以下特点:1、本发明有效地防止腐蚀性溶液对电缆线夹造成损伤,提高了聚脲的阻燃、抗静电性能,使煤矿井下抽放瓦斯安全性能大大提高,且无需制作模具,操作简便,产品为单体标准件,可根据需要任意组合拼装,便于安装、维护、更换,大大提高生产效率,降低生产成本。2、本发明比强度高、耐磨性好、抗静电阻燃、耐冷耐热保温、抗压大、韧性高、重量轻。本发明具有优异的耐腐蚀性,在腐蚀性环境下使用时,其使用寿命比普通玻璃钢材高几倍到数十倍,根据用户使用介质通过合理选材加工,均能获得满意防腐效果。使用本发明可大大提高生产、施工效率,为生产、生活提供安全保障。
