ActiveCN102783741AImprove permeabilityPromote absorptionLaminationLamination apparatusInsulation layerMetal foil
The invention relates to a preparation method and an application of multistage-spreading heat-dissipation fire-proof heat-insulation composite fabric. The multistage-spreading heat-dissipation fire-proof heat-insulation composite fabric is formed by successively arranging and laminating a metal foil reflection layer, a phase change temperature limitation layer, an interval composite membrane heat-insulation layer and a flame-retardant comfortable layer, wherein the metal foil reflection layer has high reflectivity and an enhanced heat-dissipation function; the phase change temperature limitation layer has functions of high energy consumption absorption and evenly-distributed heat conduction; the interval composite membrane heat-insulation layer has the functions of reflection insulation and even distribution of heat; and the flame-retardant comfortable layer has the functions of low-contact heat conduction, heat insulation and comfort. When the front side of the multistage-spreading heat-dissipation fire-proof heat-insulation composite fabric is under the action of open fire and strong heat flow environment, the back side of the multistage-spreading heat-dissipation fire-proof heat-insulation composite fabric can be kept below 50DEG C which is near the safe temperature state of the human skin, and the integral structural form and the mechanical property are stable. The natural thickness of the composite fabric is 5-15mm, the compression thickness of the composite fabric is 3-8mm, and the square meter quality of the composite fabric is 400-1500g / m<2>. The composite fabric is fire-proof heat-insulation material which is totally sealed, stuck and sewn and can be used for individual protection and environment heat insulation in special high-temperature occasions, such as fire control, military, exploration, safe escape and industry and the like.
