Method used

[0034] The reflective insulation layer 1 is composed of a high-reflectivity metal foil 11 and a high-temperature-resistant fiber-reinforced base cloth 12. The metal foil 11 is pure aluminum foil or aluminum alloy foil with a thickness of 5-10 μm, which has excellent reflection performance and airflow insulation performance against light and heat radiation in the high temperature and strong radiation heat flow environment of the fire scene. The temperature adaptability of the high temperature resistant fiber reinforced base cloth 12 is from room temperature to 800°C, and it is made of basalt fiber or glass fiber, and is used for strengthening, stabilizing and smoothing the metal foil 11 . Enhanced to ensure that the material is not easily damaged when hooked or punctured, so that the function of the entire fireproof fabric will not fail; stability and flatness ensure the high reflection efficiency and direct reflection function of the metal foil 11, and avoid the occurrence of multiple reflections of light on the metal foil 11 Abs...

Abstract

The invention relates to a function-shared three-composite-layer laminated flameproof fabric, a preparation technology and application. The flameproof fabric consists of a reflection heat-insulation layer which faces to a flame and is mainly formed by a high-reflectivity metal foil, a heat-consumption temperature limiting layer which is intermediately arranged and is mainly formed by a high-heat-absorptivity energy-transduction phase-change material, and a heat-insulation comfortable layer which touches a human body and is mainly formed by a high-heat-insulation and high-heat-reflectivity composite film. The reflection heat-insulation layer can reflect and insulate most heat radiated by an open-fire strong heat flow environment; the heat-consumption temperature limiting layer cuts off temperature, absorbs heat and consumes energy through the phase change of a phase-change material; and the heat-insulation comfortable layer realizes heat insulation and comfort effects through heat insulation and reflection of a multilayer composite film and a lining flameproof comfortable base fabric. The reflection heat-insulation layer, the heat-consumption temperature limiting layer and the heat-insulation comfortable layer are composite layers and are sewn and bonded in a fully-closed manner to form the composite flameproof fabric. The natural thickness of the flameproof fabric is 5-15mm, the compact thickness of the flameproof fabric is 3-10mm and the weight per square meter of the flameproof fabric is 450-1500g/m<2>. The flameproof fabric can be used for human body protection and environmental heat insulation of high-radiated-heat special occasions such as firefighting, military, exploration and industry.
