The invention provides a light-weight high-performance heat-insulating protective clothing fabric and a preparation method thereof. The light-weight high-performance heat-insulating protective clothing fabric is prepared by successively compounding the following functional structure
layers from a direction close to a fire source to a direction close to
human body: a
flame-retardant outer layer with
flame-retardant effect, a waterproof
moisture-permeable layer with waterproof and
moisture-permeable effects, and a heat-insulating layer with heat-insulating effect. The heat-insulating layer has a three-layer
composite structure, wherein the inner and outer
layers are non-
woven fabric layers; the middle layer is a
mixed layer of
aerogel and a microencapsulated
phase change material; and the structure has
high heat insulation performance, effectively reduces natural thickness and weight of clothing, thereby providing excellent protective properties and wear comfortableness for firefighters. The light-weight high-performance heat-insulating protective clothing fabric has the advantages of light weight, convenience in combination and shaping, good
reusability and wide range of application, can be used for clothing in emergency lifesaving environments like fire ground and battle ground, and can be also used as an
aerospace protective material.
