Embodiment 1

[0029] The inner side is coated with nylon 6 / halogen flame retardant mixture (softening temperature is about 210-230 degrees Celsius, because nylon is mixed with flame retardant, it is difficult to burn) glass fiber cloth is used as wear-resistant and high-strength outer bag material, and it is made after double-layer bonding It forms an automatic fireproof outer bag, which is divided into multiple fireproof airbag units, similar to the shape of a down jacket. A conventional non-woven fabric containing p-toluenesulfonate hydrazine (TSH) or ADC composite foaming agent is placed in the interlayer of the fire-resistant airbag. For fire-resistant airbags, the amount of gas-generating agent is required to ensure that the internal pressure of the fire-resistant airbag is 1-3 atmospheres after expansion.

Embodiment 2

[0034] The inner side of a glass fiber / aluminum foil composite bag with a volume of about 2 cubic meters is first coated with silicone rubber and cured. The glass fiber / aluminum foil composite bag is composed of two layers of glass fiber / aluminum foil composite cloth, and then impregnated with carbon tetrachloride. Swell to form a 5 mm expandable coating, the carbon tetrachloride is the second gas-generating agent, and then cover a layer of nylon film on the coating surface to prevent the volatilization of carbon tetrachloride, forming the heat insulation layer of the fireproof airbag packaging bag.

[0035] Continue to coat the silicone rubber mixed with AC foaming agent between the two layers of glass fiber / aluminum foil composite cloth as the first air-generating agent, and the glass fiber / aluminum foil composite cloth bag can also be sewn into fireproof airbag units one by one, and finally It is an automatic fireproof packaging bag.

Abstract

The invention provides an automatic fire-proof packaging bag which comprises a fire-proof air bag, wherein the fire-proof air bag is divided into at least one fire-proof air bag unit; the fire-proof air bag and the fire-proof air bag unit are sealed; a first gas forming agent is placed in the fire-proof air bag unit; the fire-proof air bag is bent into the packaging bag; the inner side of the packaging bag is coated with a thermal insulating layer; the thermal insulating layer is heated to form a foam thermal insulating layer capable of extinguishing a fire; and temperature of heating expansion of the thermal insulating layer is lower than that of gas forming of the first gas forming agent. The automatic fire-proof packaging bag requires no power source, is wide in application scope, and energy-saving, and allows packaged goods to be high in fire resistance.

Description

【Technical field】 [0001] The invention relates to an automatic fireproof packaging bag. 【Background technique】 [0002] Quick-closing airbags are usually used in water pipe plugging, poisonous gas plugging and fire plugging industries. The market is relatively wide. At present, the closed airbags are all inflated to achieve airbag expansion. There are two main types: [0003] 1. Manual inflation: that is to use gas storage tanks to inflate; for example, the authorized announcement number is CN202055865U, and the authorized announcement date is a Chinese patent on November 30, 2011, which discloses a mine explosion-proof manhole cover automatic sealing device for airbags. The new type includes a foldable airbag, which is placed in the foldable airbag chamber on the side of the shaft wall of the explosion-proof manhole cover, and the opening of the foldable airbag chamber communicates with the inside of the well; The shortcoming of this airbag is that it must be manually infl...
