Cryogenic heat insulation fiber felt composite material
The invention provides a cryogenic heat insulation fibrofelt composite material, which is prepared from the following raw materials in parts by mass: 100 parts of high-performance fiber, 10 to 40 parts of calcium hydroxide powder, 5 to 15 parts of ferric oxide powder, 50 to 100 parts of silica sol and 0.5 to 1 part of silicone oil. The high-performance fiber is one or more of alkali-free glass fiber, basalt fiber, aluminum magnesium fiber and silicon oxide fiber. The composite material is good in low-temperature performance, stable in structure at low temperature, low in volume shrinkage rate and good in heat insulation performance, and meets the cryogenic heat insulation requirement.
本发明提供了一种深冷绝热纤维毡复合材料，按质量计，包括以下原料：高性能纤维：100份、氢氧化钙粉体：10‑40份、氧化铁粉体：5‑15份、硅溶胶：50‑100份和硅油：0.5‑1份。所述高性能纤维为无碱玻璃纤维、玄武岩纤维、铝镁质纤维和氧化硅纤维中的一种或者多种。该复合材料的低温性能好，在低温下结构稳定，体积收缩率低，绝热性能良好，满足深冷绝热要求。
