耐高温型消防防护服复合材料的制备方法
技术领域：
本发明涉及服装材料技术领域，具体涉及一种耐高温型消防防护服复合材料的制备方法。
背景技术：
消防防护服是保护活跃在消防第一线的消防队员人身安全的重要装备品之一，它不仅是火灾救助现场不可或缺的必备品，也是保护消防队员免受伤害的防火用具。因此，它必须具有耐火性、耐热性和隔热性，还要具有突出的抗冲击性，防止锐利物体的冲击、碰撞等。现有的消防防护服面料虽然具备良好的阻燃性能，但阻燃性能还可进一步提高，以更好地保护消防员的人身安全。
发明内容：
本发明所要解决的技术问题在于提供一种耐高温型消防防护服复合材料的制备方法，该制备方法操作简便且重复性好，制得的复合材料具有良好的阻燃性能，适用于消防防护服的制作加工。
本发明所要解决的技术问题采用以下的技术方案来实现：
耐高温型消防防护服复合材料的制备方法，先将树脂基体加溶剂配成浸胶液，再将复合纤维织物完全置于浸胶液中，最后经烘干、固化得到耐高温型消防防护服复合材料。
所述树脂基体由环氧树脂和改性双氰胺固化剂组成，环氧树脂、改性双氰胺固化剂的质量比为(80-90):(10-20)。
所述改性双氰胺固化剂由双氰胺和1-萘乙胺反应制成，结构式为：
Figure BDA0002444494630000021
所述溶剂为乙醇或乙醇水溶液。
所述胶液的固含量为40-60％。
所述复合纤维织物由质量比(1-10):(0.5-5):(0.5-5)的间位芳纶纤维、麦饭石功能纤维、硅酸铝纤维棉制成。
所述硅酸铝纤维棉为硅酸铝纤维喷吹棉或硅酸铝纤维甩丝绵。
所述浸胶温度为30-50℃，浸胶时间为10-30min。
所述烘干温度为80-100℃。
所述固化温度为115-135℃。
本发明所制改性双氰胺固化剂属于新型固化剂，该固化剂相对于现有的双氰胺固化剂来说，不仅能够显著降低固化温度，而且还能优化最终所制复合材料的耐高温性能，这一技术效果是现有的双氰胺固化剂无法取得的。
为了强化最终所制复合材料的耐高温性能，本发明还对硅酸铝纤维棉进行了表面改性处理。
所述复合纤维织物由质量比(1-10):(0.5-5):(0.5-5)的间位芳纶纤维、麦饭石功能纤维、改性硅酸铝纤维棉制成，其中改性硅酸铝纤维棉的制备方法为：将硅酸铝纤维棉加热至110-130℃保温，再加入纳米氧化锆和六羟甲基三聚氰胺六甲醚，不断搅拌下继续加热至160-180℃保温，自然冷却，得到改性硅酸铝纤维棉。
所述硅酸铝纤维棉、纳米氧化锆和六羟甲基三聚氰胺六甲醚的质量比为(30-50):(0.5-3):(1-5)。
本发明所制改性硅酸铝纤维棉属于表面负载纳米氧化锆的硅酸铝纤维棉，六羟甲基三聚氰胺六甲醚起到粘接作用以将纳米氧化锆牢固负载于硅酸铝纤维棉上，从而优化硅酸铝纤维棉的耐高温性能。
本发明的有益效果是：本发明以树脂基体和复合纤维织物作为原料，通过新型双氰胺固化剂的制备来降低树脂固化温度和提高树脂的耐高温性，经浸渍、烘干、固化操作制得复合材料，制备周期短且能耗投入成本低，并且制备的复合材料显示出良好的阻燃性能，适用于消防防护服的制作加工。
