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.

Description

technical field [0001] The invention relates to a light and thin flexible composite material technology for heat insulation and protection of the human body or the environment, in particular to a high-efficiency, intelligent and long-lasting composite fireproof fabric with shared functions, the preparation process and application of the composite fireproof fabric, the composite Fireproof fabric is an important material for human body protection and environmental heat insulation in special occasions such as fire protection, military affairs, exploration, and industry. Background technique [0002] In high temperature and strong heat flow environments such as open flames, heat radiation is the most important way for heat exchange. The data show that, except for a small part (less than 30%) of convection, the heat flow generated by the fire source is mostly radiated heat in the form of electromagnetic waves to the surroundings. Due to the strong penetrating power of radiant he...
