Open fireproof and heat insulation hierarchical compound fabric, preparation process and use

Abstract

The invention relates to an open fireproof and heat insulation hierarchical compound fabric. The open fireproof and heat insulation hierarchical compound fabric is characterized in the structure of the hierarchical compound fabric, i.e. ,one surface of the fabric can bear the high temperature or high heat action of a strong heat flow open fire environment, and the other surface is kept at temperature of 45 to 50 DEG C approximate to the safety temperature of human skin. The compound structure of the compound fabric sequentially consists of a metal foil felt heat radiation reflection layer, a phase change material gradient compound felt heat absorption layer and a heat insulation comfort layer. The compound fabric has a natural thickness of 5 to 15mm, is actually 3 to 8mm thick after being compacted, is 500 to 1,500 grams per square meter, is a totally-inclosed, sewn and adhered protective material for fire protection and heat insulation, and can be used for physical protection and environmental heat insulation in special high-temperature places of fire control, military affairs, expedition, industry and the like.

Description

technical field [0001] The present invention relates to a light and thin flexible composite material technology for heat insulation and protection of human body or ambient temperature, in particular to a high-efficiency intelligent long-term fire-proof and heat-insulating multi-level composite fabric, the preparation process and application of the composite fabric, which is a fire-fighting, military It is an important material for human body protection and environmental heat insulation in special occasions such as tourism, exploration, and industry. Background technique [0002] Fire and special occasions (exploration, open fire high-temperature construction, space technology, war) all have fire protection and heat insulation requirements, so the development and application of fire-resistant and heat-insulating fabrics has always been a hot research topic. There are many potential dangers in the hot environment of the fire site: the high temperature environment of the fire s...

AI Technical Summary

Problems solved by technology

Although the fabric has good flame-retardant and anti-static properties, it will still cause burns and burns quickly when it is actually used in a high-temperature fire scene.

[0012] Although the thermal protective fabric or clothing prepared by the above patented technology has a good fire-proof and heat-insulating effect, in practical applications, the thermal protective fabric or clothing has weak flame impact resistance and short pause time in the fire field (at 800°C, t<10min), the human body will be burned or burned within a few seconds to tens of seconds when worn in a high-temperature fire field.
