Problems solved by technology

The patent is not for fire protection and the high temperature stability of the polymer based aluminum film used is poor
[0012] Although the thermal protective fabric or clothing made by the above patented technology has a certain fire-proof and heat-insulating effect, it will still cause burns or burns to the human body in a very short period of time in the actual high-temperature and strong-radiation environment. Insufficient thermal insulation and durability in the environment of strong radiant heat flow in the fire field

Abstract

The invention relates to an intelligent flameproof fabric capable of realizing step-by-step phase-change heat consumption and metal enhanced heat dissipation and a preparation technology of the intelligent flameproof fabric. The intelligent flameproof fabric consists of three to five phase-change composite layers with phase-change powder capable of exciting temperature from high to low, and an innermost flameproof comfortable layer, wherein the phase-change composite layers and the innermost flameproof comfortable layer are integrally sewn and bonded. When the front surface, i.e., the phase-change composite layer of the intelligent flameproof fabric is under the strong heat flow effect of an open fire, the back surface, i.e., the flameproof fabric of the intelligent flameproof fabric can be kept to be below 50DEG C close to safe temperature for human body skins, and the overall structural form and the mechanical property are stable. The natural thickness of the composite fabric is 5-15mm, the compact thickness of the composite fabric is 3-8mm and the weight per square meter of the composite fabric is 400-1500g / m<2>. The intelligent flameproof fabric is a fully-closed bonded and sewn flameproof heat-insulation fabric and can be used for individual protection and environmental heat insulation of high-temperature special occasions such as firefighting, military, exploration, safe escape and industry.

Description

technical field [0001] The present invention relates to a kind of frivolous and flexible intelligent composite material technology for thermal insulation and protection of human body or environment temperature, in particular to an intelligent fireproof fabric with step-by-step phase change heat consumption and metal-enhanced heat dissipation and its preparation process. The intelligent fireproof fabric is applicable to It is suitable for human body protection and environmental heat insulation in special occasions such as fire protection, military affairs, exploration, and industry. Background technique [0002] High-temperature special environments such as fire sites (exploration, open flame high-temperature construction, war) are relatively complex environments, and three heat transfer modes of conduction heat, convection heat and radiation heat coexist. The research on the measurement of the fire environment shows that the radiation heat plays a leading role in the fire he...
