Production method of nano microporous thermal insulation material
The invention discloses a production method of a nano microporous thermal insulation material, which comprises the following steps: mixing common fibers and high-temperature-resistant inorganic fibers according to a ratio of 1: 1.5 to obtain mixed fibers; the mixed fibers are added into an opener for fiber dispersion, and then impurities in the mixed fibers are removed; mixing hydrophilic silicon dioxide, an opacifying agent and the mixed fibers in the step S2 to obtain a mixture; s3, adding the mixture in the step S3 into a mold for pressing to obtain the vacuum insulation panel; in the step S2, after the mixed fibers are opened, the mixed fibers are sequentially stirred and compressed into a flat shape, and finally the mixed fibers are opened again to obtain dispersed fibers, the production cost of the thermal insulation material is reduced, and the effect of coordinating the high-temperature performance and the mechanical performance of the thermal insulation material is achieved.
本发明公开了一种纳米微孔绝热材料的生产方法，将普通纤维和耐高温无机纤维按照比例进行混合得到混合纤维，两者的混合比例为1:1.5；将混合纤维加入到开松机中进行纤维分散，随后除去混合纤维中的杂质；将亲水二氧化硅、遮光剂、S2步骤中的混合纤维进行混合得到混合物；将S3中的混合物加入到模具中进行压制，得到真空绝热板；在步骤S2中，混合纤维在经过开松以后，依次进行搅拌，压缩为扁平状，最后再次进行开松得到分散的纤维，本发明不仅降低了绝热材料的生产成本，而且起到了协调绝热材料高温性能和力学性能的效果。
