Embodiment Construction

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0031] A multi-layer composite material fire-extinguishing blanket, which is in the shape of a blanket, is made of soft high-silica refractory fiber and fibrous activated carbon filter cloth, and is continuously sewn with 0.3 mm heat-insulating and flame-retardant tweezers on the four sides; The high-silica glass fiber and the fibrous activated carbon filter cloth are all high-performance high-temperature resistant inorganic composite fibers, and the main component of the high-silica glass fiber is silicon dioxide (SiO 2 ). The silicon dioxide (SiO 2 ) content is higher than or equal to 96%, the softening point is close to 1700°C, and it can be used for a long time at 900°C. The maximum operating temperature of the fibrous activated carbon filter cloth is 1000°C, which can reach the ignition point of air above 500°C, and at the same time, it...

Abstract

The invention provides a multilayer composite material fire extinguishing blanket, which is characterized in that the fire extinguishing blanket is provided with the structure of fiber-shaped active carbon filter cloth which is nipped between the two layers of high silica glass filter cloth. The fire extinguishing blanket made by the principle of good anti-heat performance of the high silica glass fire cloth and fiber-shaped active carbon filter cloth covers the fire source, and can obstruct the air to reach the object of fire extinguishing; the fire extinguishing blanket has the effective heat insulation function of external protection layer for the persons and objects; meanwhile, on the condition without fire situation, the fiber-shaped active carbon filter cloth in the multilayer composite material fire extinguishing blanket has the functions of air purification, filtration and adsorption of the harmful gas in the air such as the poison gas, smoke, effluvium, etc., and the environmental protection; furthermore, the high silica glass fiber and the fiber-shaped active carbon filter cloth are non-asbestos products, belonging to environmental protection material without pollution.

Description

technical field [0001] The invention relates to heat-insulating, flame-retardant and fire-extinguishing products for fire-fighting supplies and air-purifying products in the field of environmental protection, in particular, it includes two layers of high-silica glass fiber cloth, and a fibrous activated carbon filter cloth is sandwiched between the two layers of high-silica glass fiber cloth , using the principle of high silica glass fiber cloth and fibrous activated carbon filter cloth with good heat resistance to cover the fire source, it can block the air to achieve the purpose of fire extinguishing. The fire blanket can effectively insulate the human body and objects The outer layer is protected. At the same time, when there is no fire, the fibrous activated carbon filter cloth in the multi-layer composite fire blanket can purify the air, and can filter and absorb harmful gases such as poisonous gas, smoke, and odor in the air. , Play an environmental protection role, and ...
