Description

真空绝热材料的制造方法
技术领域
本发明涉及一种绝热材料，尤其是一种真空绝热材料的制造方法，属于隔热材料技术领域。
背景技术
目前常用的真空保温绝热材料由于结构的特殊性，芯材一般采用软质的绝热材料作保温隔热层，如炭矿棉、玻璃棉、二氧化硅及气凝胶等无机化合物，包裹材料一般使用尼龙/PET/铝箔或者PE等作为包裹层。玻璃棉、炭矿棉等需要经过预处理工艺才能作为真空绝热材料的芯材，直接使用会容易受外力作用而使纤维之间发生相互堆积的现象，因此芯材一般都要用针刺工艺或者采用粘结剂以避免材料之间的互相堆积。但粘结剂等可能会使得真空隔热材料的性能不稳定。
发明内容
本发明的目的是克服现有技术中存在的不足，提供一种真空绝热材料的制造方法，保证材料的性能稳定，避免绝热效果下降。
按照本发明提供的技术方案，所述真空绝热材料的制造方法，其特征是，包括下以步骤：
（1）准备聚丙烯纤维，采用聚丙烯纤维在针刺机上制备得到芯片；在70-80℃的温度下将上述芯片干燥24小时，重叠得到芯材；
（2）向芯片中喷洒吸收剂，吸收剂采用生石灰；然后由上至下依次布置PET薄膜、尼龙膜、铝箔和线性低密度聚乙烯膜，得到包裹层；向包裹层中放入步骤（1）所述的芯材，采用包裹层包裹芯材，得到所述的真空绝热材料。
进一步地，所述聚丙烯纤维的直径为10-15μm、长度为2-3mm。
进一步地，所述步骤（1）得到的芯材的克得为15-20g/m2。
进一步地，所述真空绝热材料的热传导率为4-4.5mW/mK。
本发明所述真空绝热材料的制造方法，能够保证材料的性能稳定，从而有效避免了绝热效果下降。
