Problems solved by technology

[0009] The technical problem to be solved by the present invention is: the existing outer fabric of fire-fighting and heat-insulating protective clothing adopts the form of bonding aluminum foil and the base cloth, which is easy to bend and leads to poor durability; while the prior art uses aluminum-plated materials as the production Flame-retardant and heat-insulating fabrics have insufficient thermal radiation resistance. Increasing the thickness of the aluminized layer results in heavier weight, poor flexibility, and uneven distribution of overall stiffness / flexibility, resulting in adhesion between the aluminized carrier layer and the base fabric layer. After bonding, the local stress is relatively large, and there is a risk of reverse bonding when bonding with the base fabric layer. At the same time, when the aluminum layer is damaged, the thermal radiation resistance will immediately drop sharply, thus posing a certain safety hazard.

Abstract

The invention relates to a layered structure of a fabric, in particular to an outer fabric of fire-fighting and heat-insulating protective clothing, belonging to the technical field of fire-fighting and heat-insulating protective clothing. An outer fabric for fire-fighting and heat-insulating protective clothing, characterized in that it includes a first aluminized layer, a high-temperature-resistant polymer film layer, a second aluminized layer, an adhesive adhesive layer, and a base cloth layer; the first aluminized layer layer and the second aluminum-coated layer are plated on both sides of the high-temperature-resistant polymer film layer, and the second aluminum-coated layer and the base cloth layer are bonded by an adhesive layer. The double-sided aluminum plating of the high temperature resistant polymer film has good anti-radiation heat penetration performance, which makes the fabric have an excellent function of reflecting radiant heat; the high temperature resistant polymer film and the aluminum coating layer are closely combined to strengthen the aluminum coating layer effect.

Description

technical field [0001] The invention relates to a layered structure of a fabric, in particular to an outer fabric of fire-fighting and heat-insulating protective clothing, belonging to the technical field of fire-fighting and heat-insulating protective clothing. Background technique [0002] Firefighters' heat-insulating protective clothing is the protective equipment worn by firefighters when they are exposed to strong radiant heat during fire fighting and rescue operations. At present, they are mainly used for fires such as petroleum, chemical, ship and aircraft accidents. They can withstand heat sources above 1000 ℃ In the environment of strong radiant heat, it provides heat insulation protection, and has the functions of waterproof and water vapor, and is suitable for firefighters to wear when they are close to fire fighting operations. The fabric of the existing common fire-fighting and heat-insulating protective clothing generally adopts the structural form of aluminum...
