Problems solved by technology

The patent is not for fire protection, and the high temperature stability of the polymer-based aluminum film used is very poor, and the preparation method is different
[0009] Although the thermal protective fabric or clothing made by the above patented technology has a good fire-proof and heat-insulating effect, in the actual high-temperature and strong-radiation environment, it will still form local overheating in a very short period of time, causing burns or burns to the human body, and damage caused by impact. and puncture cuts cause fabric damage and thermal protection system failure

Abstract

The invention relates to a fire-proof insulating composite fabric with a multi-layer reflection and phase-change function and an application thereof. The fire-proof insulating composite fabric is formed by inwards laminating at least one group of high-reflectivity metal foils facing to flame, non-woven fabric for supporting the metal foils and a non-woven blanket with phase change powder one by one. By adding the innermost layer of flame-resistant fabric, the fire-proof insulating composite fabric is formed, or the composite fabric without flame-resistant fabric is directly laminated with temperature-resistant and heat-insulating material in other forms. According to the composite fabric disclosed by the invention, the outer side of the flame-resistant fabric is kept below 50DEG C which is safe to the human body skin by multi-group lamination. The natural thickness of the composite fabric is 5-30mm, the practical compression thickness of the composite fabric is 3-15mm, and the single-group square meter weight of the composite fabric is 100-400g / m<2>; and the composite fabric is completely sealed, sewn and stuck, is suitable for protection and heat insulation materials in places and fire scenes at the high temperature of 500-1000DEG C, and can be used for the human body protection and environment heat insulation of high-temperature special occasions, such as fire control, military, exploration and industry.

Description

technical field [0001] The present invention relates to a kind of frivolous and flexible composite material technology for heat insulation and protection of human body or environment temperature, in particular to a fire-proof and heat-insulating composite fabric with multi-layer reflection and phase change functions and the application of the composite fabric, which is used for fire protection, military affairs, exploration, It is an important material for human body protection and environmental heat insulation in special occasions such as industry. Background technique [0002] Radiation heat is the dominant heat transfer method in high-temperature special occasions such as fire sites (such as expeditions, high-temperature construction with open flames, wars, etc.). The data show that the temperature of the open flame fire site is 60-1100°C, the proportion of radiant heat in the heat flow is 50-60%, and the peak value of radiant heat flux is concentrated at 167.5kW / m 2 ~22...
