Outer fabric of heat-insulating protective clothing for firefighters and manufacturing method thereof

Abstract

The invention provides an external layer fabric of heat insulation protective clothing for a firefighter and a manufacturing method thereof, wherein the external layer fabric of the heat insulation protective clothing for the firefighter is aramid fiber 1313 with an external surface coated with an alumina gel A and an alumina gel B in order, wherein the alumina gel A is prepared from the raw materials by weight: 100 parts of oily polyurethane, 5-10 parts of adhesion agent, 20-30 parts of cyclized phosphate ester fire retardant, 15-20 parts of butanone, and 4-8 parts of aluminum powder; the alumina gel B is prepared from the raw materials by weight: 100 parts of oily polyurethane, 5-10 parts of adhesion agent, 20-30 parts of cyclized phosphate ester fire retardant, 20-30 parts of butanone, and 7-10 parts of aluminum powder The external layer fabric not only can reflect heat of high temperature heat radiation, but also has good moisture permeable performance; the external layer fabric provided by the invention has very good flame resistance, completely accords with an external layer fabric standard of the heat insulation protective clothing GA10-2002 for the firefighter; and the external layer fabric has advantages of soft handle and strong comfortableness for wearing.

Description

technical field [0001] The invention belongs to the field of protective clothing fabrics for firefighters, and in particular relates to an outer layer fabric of heat-insulating protective clothing for firefighters and a manufacturing method thereof. Background technique [0002] The thermal insulation protection ability of firefighting clothing has a crucial impact on the rescue efficiency of firefighters in high temperature environments. For now, the heat-insulating protective clothing for firefighters is mainly composed of three parts: the outer fabric, the heat-insulating layer, and the comfort layer. The outer fabric is mainly composed of aluminum foil and aramid fiber fabric or laminated with glass fiber fabric. In a high temperature environment, the aluminum foil can effectively reflect high-temperature heat radiation heat; the heat insulation layer is mainly aramid non-woven fabric or flame-retardant cotton , which can effectively prevent the heat transfer from the o...

AI Technical Summary

Problems solved by technology

The outer fabric of heat-insulating protective clothing is a layer that is directly in contact with high temperature. At present, although the outer fabric is composited with aluminum foil and aramid fiber fabric or glass fiber fabric, it can effectively reflect the high-temperature heat generated by the flame. However, aluminum foil and aramid fiber The composite process of fiber fabric is quite difficult. In the composite process, proper tension control must be selected to ensure that the aluminum foil surface will not be damaged or wrinkled after composite. In addition, the outer fabric of the aluminum foil composite base fabric is less comfortable to wear. This is because aluminum foil is a non-flexible material. After compounding on the base fabric, the entire outer fabric feels stiff. When worn on the body, it will make firefighters' fire fighting and rescue actions very inflexible. Moreover, aluminum foil is a non-moisture-permeable material. The sweat and water vapor emitted by the firefighters during the battle are blocked in the heat insulation layer and the comfort layer, which will make the firefighters feel stuffy, which greatly affects the combat efficiency of the firefighters
