The utility model relates to a heat insulation layer of firefighter's fire-fighting protective clothing, which comprises a base layer integrated with a polytetrafluoroethylene film and a base cloth. The utility model is characterized in that the front and back sides of the base layer are coated with inorganic flame-retardant heat insulation The said inorganic flame-retardant heat-insulating layer is coated on the base layer at intervals, and rubber columns are arranged in a matrix on the inorganic flame-retardant heat-insulating layer on the back of the base cloth. Lightweight, breathable, heat-insulating, and fire-retardant.

 

As the basic personal protective equipment, firefighters' fire-fighting protective clothing is the protective clothing that firefighters must wear when conducting fire-fighting operations. Its structure is composed of four layers of materials, including an outer layer, a waterproof and breathable layer, a heat insulation layer and a comfort layer. According to many years of research conclusions at home and abroad, among the influencing factors of the performance of firefighter protective clothing, the optimization requirements for weight and comfort performance account for si%. At present, the material of the thermal insulation layer of the firefighter's protective clothing is a spunlace felt structure. In order to ensure the thermal insulation performance, the structure is relatively fluffy. Therefore, the thermal insulation layer will absorb a large amount of sweat of the firefighter during the high-strength operation in the fire field, thereby reducing the weight Thermal protection performance causes a large adverse effect. The Chinese patent "Insulation layer material of firefighter's fire-fighting protective clothing" (application publication number CN 104013146 A; application publication date 2014.09.03) discloses an insulation layer of firefighter's fire-fighting protective clothing. The vinyl film and the base fabric of the heat insulation layer are arranged in an integrated manner. This single-layer structure achieves the heat insulation effect of the double-layer insulation layer. A rubber column is arranged on the integrated single-layer structure to increase the thermal expansion of the rubber column. The thermal insulation of the thermal insulation layer of the firefighter's fire-fighting protective clothing will help reduce the weight of the fire-fighting protective clothing, improve the comfort of wearing, and ensure the personal safety of firefighters. However, in the actual application of this kind of firefighter's fire-fighting protective clothing thermal insulation layer, there is a possibility that the thermal insulation layer may burn at a high temperature in the fire-fighting activities. Therefore, it is necessary to ensure that the thermal insulation layer is light, breathable, and thermally insulated. Next, it is also necessary to ensure that the thermal insulation layer is fireproof and flame retardant.
