The invention discloses a satellite surface multi-layer heat insulation assembly with high electromagnetic environment protection capacity. The satellite surface multi-layer heat insulation assembly comprises a laminated assembly and an anti-electromagnetic reinforcing mask group covering the surface of the laminated assembly; the anti-electromagnetic reinforcing mask group is connected with the laminated assembly in a sewing manner through a sewing line; the surface of the laminated assembly is coated with the anti-electromagnetic reinforcing mask group, the laminated assembly and the anti-electromagnetic reinforcing mask group are sewn through the sewing line, the anti-electromagnetic reinforcing mask group is provided with the polyimide layer and the metal layer, the metal layer is relatively close to the laminated assembly, the laminated assembly faces a protected product during use, and the polyimide layer faces the external environment; the polyimide layer has good thermal control temperature characteristic and total dose effect, and the metal layer has the effects of electromagnetic radiation resistance and self damage resistance, so that the heat insulation assembly can be effectively prevented from being burnt down, and a protected product is prevented from being interfered by strong electromagnetic waves.
