Description

一种安全保健消防服用隔热材料及其加工工艺
技术领域
本发明涉及消防产品技术领域，尤其涉及一种安全保健消防服用隔热材料及其加工工艺。
背景技术
消防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，也是保护消防队员身体免受伤害的防火用具，因此，适应火灾现场救助活动的消防服就显得尤为重要。消防服一般具有多层结构，从外到内依次为阻燃耐火材料层、防水透气层、隔热层和舒适层，目前的隔热材料能提供对消防员的隔热保护，免受高温和辐射热伤害，然而目前用于消防服的隔热材料自身重量大，透气性能差，隔热效果不佳，影响了夏季穿着的舒适性。
发明内容
本发明的目的是克服现有技术的不足，提供一种安全保健消防服用隔热材料，具有良好的隔热阻燃性，防烫隔热效果好，防火等级高，防水效果好，重量轻，透气性好，触感凉爽，而且具有抗菌功能，可以促进人体血液循环。
本发明的另一目的是提高该安全保健消防服用隔热材料的加工工艺。
为了实现上述目的，本发明采用如下技术方案：
一种安全保健消防服用隔热材料，包括以下重量份的原料：改性混合纤维60-80份、电气石粉5-10份、硅烷偶联剂0.3-0.5份、水性聚氨酯10-12份、膨胀石墨1-3份、硅藻土1-3份、聚磷酸铵3-5份、六水氯化镁10-15份、木槿皮3-5份、板栗壳3-5份、粘合助剂3-6份；
所述改性混合纤维由以下方法制备：
(1)按重量份将亚麻纤维30-45份、岩棉纤维20-30份、竹纤维10-20份、海泡石纤维10-20份、玉石纤维10-20份混合得混合纤维；
(2)取蒙脱土加入水中，持续搅拌使得蒙脱土均匀分散在水中，得到浓度为5-10g/L的蒙脱土分散液；将聚乙烯醇加入所得的蒙脱土分散液中，并加热至80℃，持续搅拌至聚乙烯醇完全溶解，得到聚乙烯醇浓度为5-10g/L的改性液；
(3)将步骤(1)的混合纤维浸入步骤(2)的改性液中，并持续搅拌10-30分钟，过筛将混合纤维滤出，并将滤出的混合纤维烘干至恒重；再将所得混合纤维浸入浓度为2-5％戊二醛水溶液中，并升温至60℃保持10-30分钟，而后过筛将混合纤维滤出，并将滤出的混合纤维干燥至恒重，得到改性混合纤维。
所述的粘合助剂由以下方法制备：按重量份取偏硅酸钠10-15份、糯米粉5-10份、聚乙烯醇2-4份、桃胶4-6份、黄原胶2-4份、硼酸1-2份、水20-30份；制备步骤为：先向水中加入聚乙烯醇并于80-90℃条件下搅拌10-20分钟，再加入桃胶、黄原胶和硼酸于60-80℃、400-600转/分钟搅拌1-2小时，最好加入剩余原料搅拌4-6小时即得。
所述的安全保健消防服用隔热材料的加工工艺，包括以下步骤：
(1)将电气石粉与硅烷偶联剂混合，加入混合物重量2倍的水，调浆后倒入球磨机中进行超细研磨，球磨后过滤烘干得超细粉末，将超细粉末放入到搅拌器中，加入水性聚氨酯，升温至40℃，以600-800转/分的速度分散30分钟，继续升温至60℃，保温2-3小时后，降至室温后，烘干即得表面活化的电气石细粉；
(2)将膨胀石墨、硅藻土、木槿皮、板栗壳放入球磨机中干磨50-60分钟后过180目筛形成混合粉末备用，将六水氯化镁中加入2倍量的水将其充分溶解形成溶液，静置24小时后放入搅拌机中，然后依次加入混合粉末、聚磷酸铵、粘合助剂以及步骤(1)得到的表面活化的电气石细粉，以500转/分的速度搅拌10-15分钟，形成糊状物料；
(3)将改性混合纤维经过开松机开松，然后将步骤(2)的糊状物料均匀倒入开松后的混合纤维之间，自然晾干2-3天，然后通过交叉铺网机铺网然后进入牵伸机形成交叉铺网的纤维网，称王后的材料经水刺机中的水刺头的水针和孔径为0.1mm的水针板配合使用，并在水刺压力为100-120bar的压力下喷射加固，然后通过烘干机烘干即可。
与已有技术相比，本发明的有益效果如下：
(1)本发明的安全保健消防服用隔热材料，采用多种具有阻燃效果的纤维改性后共混纺织而成，阻燃效果显著，其中亚麻纤维保健抑菌，防污抗静电，防紫外线，并且阻燃效果极佳，适合夏季使用；海泡石纤维不仅具有超强的阻燃性，而且导热慢，绝缘性好，对人体无不良刺激；玉石纤维和竹纤维的添加增加了面料的凉爽感，与皮肤接触能改善微循环，促进新陈代谢，消除疲劳感。
(2)本发明采用改性的混合纤维，由于加入的阻燃性纤维由于本身存在大量羟基，因而具有很强的亲水性，同时，由于混合纤维本身所具有的多孔结构导致其有很强的吸水性吸湿气性，从而导致混合纤维制成的消防服防水效果差，容易在湿热环境下发生力学性能降低及尺寸不稳定等现象。本发明将混合纤维进行改性，首先在混合纤维表面吸附聚乙烯醇分子，而后利用聚乙烯醇与戊二醛交联剂的高反应活性，形成表面疏水结构以降低混合纤维的吸水性，大大提高改性后混合纤维的表面取代度，可以取得较好的疏水效果，同时，采用蒙脱土作为改性剂改善混合纤维力学强度，蒙脱土在充分分散之后本身具有特殊的片状结构，该结构是蒙脱土本身所具有的微观形态，改性液中分散有蒙脱土纳米粒子，同时溶解有聚乙烯醇，当混合纤维与改性液混合有，表面同时吸附聚乙烯醇分子以及蒙脱土纳米粒子，由于聚乙烯醇与蒙脱土已在改性液中充分混合，因此混合纤维表面吸附的聚乙烯醇分子与蒙脱土纳米粒子也形成了均匀的混合，而后利用聚乙烯醇与戊二醛交联剂的高反应活性，形成表面疏水结构以降低木纤维的吸水性，大大提高了改性后木纤维的表面取代度，可以取得较好的疏水效果，同时，由于蒙脱土与聚乙烯醇的充分混合，其片状结构均匀分散于聚乙烯醇基底之中，延长水分子扩散路径从而达到进一步降低混合纤维吸水性的目的。
(3)本发明添加膨胀石墨、硅藻土作为填充料，配合聚磷酸铵，大大提高成品的防火效果，达到不燃的等级；添加表面改性的电气石细粉以及木槿皮、板栗壳，能够提高粉末的分散性，进而提高粉末的远红外线发射率以及负离子的释放率，而且具有抗菌、灭菌功能和促进人体血液循环的保健功效，提高了产品的性能；
(4)本发明的安全保健消防服用隔热材料，具有良好的隔热阻燃性，防烫隔热效果好，防火等级高，防水效果好，重量轻，透气性好，触感凉爽，而且具有抗菌功能，可以促进人体血液循环。
