技术领域
本发明涉及一种面料领域，具体涉及一种二氧化硅中棉保温材料及其生产工艺。
背景技术
传统的面料只有保温功能，不具备自发热功能，想要实现自发热，需要在面料的基础上增加其他额外的材料才能实现。但是面料和材料的组合往往会让面料产生诸多问题，比如：弹性和厚度等。另一方面，这些自发热面料往往又不具备了保温功能，属于无法兼顾。因此，想要保温和自发热两者兼顾；同时又不会影响面料性质就是行业内的难题。
因此，为了解决上述问题进行了一系列改进。
发明内容
本发明的目的在于，提供一种二氧化硅中棉保温材料及其生产工艺，以克服现有技术所存在的上述缺点和不足。
一种二氧化硅中棉保温材料的生产工艺，包括：

步骤2：在步骤1的结构体上，喷洒碳系无机粒子；
步骤3：将步骤2的结构体，送入150～200度的烘箱，TPU热熔粉加热融化，产生粘合，将步骤2的结构体的材料粘合为一个整体；
步骤4：将涤纶中棉层平铺，并在上方制作TPU热熔层；
步骤5：将步骤4的结构体，送入150～200度的烘箱，使TPU热熔层受热融化产生粘性，牢固附着在涤纶中棉层上；
步骤6：在步骤5的结构体上，喷洒二氧化硅气凝胶粉体；

步骤8：在步骤7的结构体上，铺设网状TPU层；
步骤9：将步骤3的结构体，铺设在步骤8的结构体上，送入150～200度高温烘箱高温热熔，将网状TPU层热熔融化产生粘合力，使材料粘合成一个整体；
其中，所述步骤2中的碳系无机粒子的颜料含有率的重量百分比为2.4％，所述步骤2中的碳系无机粒子的组分为：特性粘度为0.60dl/g的聚对苯二甲酸乙二醇酯和炭黑含有率的重量百分比1的母料。
进一步，所述步骤2中的碳系无机粒子的生产步骤包括：
步骤1：制造炭黑含有率的重量百分比16的母料；
步骤2：将步骤1的母料与特性粘度为0.60dl/g的聚对苯二甲酸乙二醇酯混合，使其混合物的颜料含有率的重量百分比为2.4％；
步骤3：将步骤2的混合物在290℃下熔融，从具有孔数为36的喷丝头，以纺丝温度290℃、排出量42g/min、纺丝速度1500m/分钟进行熔融纺丝，卷绕未拉伸丝；
步骤4：将步骤3得到的未拉伸丝在拉伸温度90℃、拉伸倍率3.3倍下进行辊拉伸，接着用180℃的非接触型加热器进行热置而卷绕，得到拉伸丝；
步骤5：把这种拉伸丝剪掉，制成短纤维后既是碳系无机粒子。
进一步，一种二氧化硅中棉保温材料，包括：涤纶中棉层、TPU热熔层、二氧化硅层、网状TPU层、碳系无机粒子层和TPU热熔粉层，所述TPU热熔层设于涤纶中棉层上，所述二氧化硅层设于TPU热熔层上，所述网状TPU层设于二氧化硅层上，所述碳系无机粒子层设于网状TPU层上，所述TPU热熔粉层设于碳系无机粒子层上，所述TPU热熔粉层上覆盖有另外一层涤纶中棉层。

具体实施方式
以下结合具体实施例，对本发明作进步说明。应理解，以下实施例仅用于说明本发明而非用于限定本发明的范围。
实施例1
图1为本发明的拆解结构图。
一种二氧化硅中棉保温材料的生产工艺，包括：
步骤1：在涤纶中棉层上，喷洒TPU热熔粉，TPU热熔粉是一种受热融化的粘合材料；
步骤2：在步骤1的结构体上，喷洒碳系无机粒子；
步骤3：将步骤2的结构体，送入150～200度的烘箱，TPU热熔粉加热融化，产生粘合，将步骤2的结构体的材料粘合为一个整体；
步骤4：将涤纶中棉层平铺，并在上方制作TPU热熔层，这个TPU热熔层与步骤2不同，它不是粉状结构，而且圆柱体结构；
步骤5：将步骤4的结构体，送入150～200度的烘箱，使TPU热熔层受热融化产生粘性，牢固附着在涤纶中棉层上；
步骤6：在步骤5的结构体上，喷洒二氧化硅气凝胶粉体；
步骤7：将步骤6的结构体，送入150～200度的烘箱，TPU热熔层受热融化后，将表层覆盖的二氧化硅气凝胶粉体，粘合固定住；
步骤8：在步骤7的结构体上，铺设网状TPU层；
步骤9：将步骤3的结构体，铺设在步骤8的结构体上，送入150～200度高温烘箱高温热熔，将网状TPU层热熔融化产生粘合力，使材料粘合成一个整体；
其中，步骤2中的碳系无机粒子的颜料含有率的重量百分比为2.4％，步骤2中的碳系无机粒子的组分为：特性粘度为0.60dl/g的聚对苯二甲酸乙二醇酯和炭黑含有率的重量百分比1的母料。
步骤2中的碳系无机粒子的生产步骤包括：
步骤1：制造炭黑含有率的重量百分比16的母料；
步骤2：将步骤1的母料与特性粘度为0.60dl/g的聚对苯二甲酸乙二醇酯混合，使其混合物的颜料含有率的重量百分比为2.4％；
步骤3：将步骤2的混合物在290℃下熔融，从具有孔数为36的喷丝头，以纺丝温度290℃、排出量42g/min、纺丝速度1500m/分钟进行熔融纺丝，卷绕未拉伸丝；
步骤4：将步骤3得到的未拉伸丝在拉伸温度90℃、拉伸倍率3.3倍下进行辊拉伸，接着用180℃的非接触型加热器进行热置而卷绕，得到拉伸丝；
步骤5：把这种拉伸丝剪掉，制成短纤维后既是碳系无机粒子。
如图1所示，一种二氧化硅中棉保温材料，包括：涤纶中棉层100、TPU热熔层200、二氧化硅层300、网状TPU层400、碳系无机粒子层500和TPU热熔粉层600，TPU热熔层200设于涤纶中棉层100上，二氧化硅层300设于TPU热熔层200上，网状TPU层400设于二氧化硅层300上，碳系无机粒子层500设于网状TPU层400上，TPU热熔粉层600设于碳系无机粒子层500上，TPU热熔粉层600上覆盖有另外一层涤纶中棉层100。
本发明的核心技术就是能够自发热同时又可以强力保温的材料，这种材料可以直接制作成面料使用，不需要额外添加其他材料，保证了面料的性能。其原理是：自发热是利用碳系无机粒子，碳系无机粒子会吸收太阳光能量，放射远红外线。因此在吸收了光线后，可以使棉的表面容易变暖，发挥蓄热保温效果。通过工艺和配方的设计，目的是为了让这种材料能够与其它材料进行组合，因此才设计成这种短纤维结构。而保温，则是通过二氧化硅层300实现，二氧化硅气凝胶是目前已知的最轻的固体。中空性达到99％。是一种极强的保温个人材料，广泛应用于航天航空保温领域。二氧化硅气凝胶粉体喷洒在整体结构之中，起到了上下隔断温度的作用。对增强材料隔热保温性，起到极大的决定性作用。
以上对本发明的具体实施方式进行了说明，但本发明并不以此为限，只要不脱离本发明的宗旨，本发明还可以有各种变化。
