Spacecraft shell repairing and heat-insulating foaming material
The invention discloses a thermal insulation foaming material for repairing a spacecraft shell. The thermal insulation foaming material comprises the following components: 80-100 parts of high-aluminum clinker, 2-5 parts of phosphoric acid and 1-1.5 parts of phosphor-copper conductive adhesive. The method has the beneficial effects that the porosity can reach 50%, the density is 300 g/cm < 3 >, the compressive strength is 25 MPa, the pore number is 0.915, the solidification rate is 1 h, polyurethane foam is mixed for use during repairing, the tolerable temperature reaches 1500 DEG C, the ultraviolet transmittance is 0.1%, the x-ray transmittance is lower than 0.1%, the volume expansion rate is lower than 5%, and the thermal insulation foam material can be repaired. The double functions of repairing and heat insulation are achieved.
本发明公开了一种航天器外壳修复隔热发泡材料，包括以下组分：高铝熟料80‑100份，磷酸2‑5份，磷铜导电胶1‑1.5份。本发明的有益效果：通过该修复隔热发泡材料，可达到孔隙率50％、密度300克每立方厘米、抗压强度25兆帕、孔隙数为0.915，凝固速率1小时，在修复时采用聚氨酯泡沫混合使用，耐受温度达到1500度、紫外线透过率0.1％、x射线透过率低于0.1％，体膨胀率小于5％，实现了修复且隔热的双功能。
