Abstract
The present invention relates to a flame resistant bag, which relates to the field of fire prevention plugging materials, particularly to a bag-shaped refractory material. The present invention is used for solving the problems of complicated manufacturing technology of flame resistant refractory materials, large investment, large weight, inconvenient use, etc. of the existing flame resistant bags. The flame resistant bag is composed of a flame resistant packaging bag which is filled with flame resistant refractory materials; the flame resistant refractory materials are mixed by the components measured by the following weight portions: 10 to 20 of acrylate emulsion, 15 to 25 of ammonium polyphosphate fire retardants, 6 to 16 of expandable graphite, 5 to 10 of hollow micro spheres, 1 to 4 of hydroxyethyl cellulose, 20 to 30 of calcium carbonate and 8 to 15 of water; the flame resistant packaging bag is made from low alkali glass fiber cloth with fine meshes or no alkali glass fiber cloth with fine meshes; an inner packaging bag in the flame resistant packaging bag is a thick plastic bag. The present invention is suitable for fire resisting partition walls or refractory isolated layers of cable tunnels and cable vertical shafts of power plants, transformer substations, industrial and mining factory buildings, high buildings, etc. and has a heat insulation effect and a refractory effect.
Description
Technical field
The invention belongs to the fire-proof sealing material field, be specifically related to a kind of bag shape refractory material.
Background technology
Architectural fire safety, separation are the design philosophys of extensive employing.But fire-resisting partition and floor are usually run through by auxiliary equipment such as cable, groove canal, pipeline etc., and its integrality is damaged, and has stayed serious disaster hidden-trouble.Now, fireproof blocking being carried out in these holes and slit has been a common recognition and requisite measure.The back-fire relief bag of being used widely in fireproof blocking (also claiming fire prevention bag, fire-resistant bag) is with not firing or the material of anti-flammability is constrained to refractory material the bag shape body of all size, can be piled into the body of wall of various forms, as fire-resisting partition or fire-resistant interlayer, perhaps be used for shutoff than macroscopic void.
Disclosed a kind of expansion type cable fire-retardant bag among the Chinese patent CN1073707 (91111989.2), by the Glass Fibre Bag amount of packing into by weight percentage by rock wool 65～85%, diatomite or alumina 2～5%, silicone adhesive 3～8%, white vermiculite 15～20% mix the flame-retardant material of forming and constitute.Flame-retardant material wherein is through the stirring-granulating moulding, and technology is complicated, and use equipment is more, and investment is big.White vermiculite proportion in the flame-retardant material is bigger, and large usage quantity makes that whole back-fire relief bag weight is big, uses inconvenience.
Disclosed a kind of fire prevention bag among the Chinese patent CN1199080 (97103272.6) is made of fire-retardant packaging bags flame-retardant material.The flame-retardant material is made up of the inorganic intumescent layer of the cryosphere that contains mineral wool and/or rock wool layer, inorganic binder and inorganic anti-flaming material, the heat zone of alumina silicate fibre, and its technological process of production is long, comparatively complicated.Fire-retardant packaging bag is polypropylene flame redardant, polythene film bag or woven bag, is subjected to fire promptly to suffer breakage a little, is not easy to the fire prevention bag and reuses.
Summary of the invention
In view of above-mentioned, purpose of the present invention overcomes above-mentioned prior art shortcoming exactly, provides a kind of fire endurance height, production technology simple and can reusable back-fire relief bag.
For realizing purpose of the present invention, at first be that the compound water emulsion of flame-retardant material selection is as base-material, its vitrification point is low, and better heat-resisting and good caking property and weather-proof resistance to water are arranged, and the back-fire relief bag of preparing with this emulsion has the high and physicochemical property excellent characteristic of fire endurance.Next is to have adopted the intumescent technology path, and back-fire relief is wrapped in when being subjected to fire, and material can be expanded foamed in the bag, form the low cellular monoblock of thermal conductivity factor, thereby improve the fire endurance of back-fire relief bag, can stop spreading of flame, flue gas effectively, fire is controlled at subrange.Moreover adopt glass fabric to make packaging bag.
Back-fire relief bag of the present invention is made of the fire-retardant packaging bag flame-retardant material of packing into, and the flame-retardant material is mixed by the component of following metering by weight and forms:
Chlorine partial emulsion 10～20
Ammonium polyphosphate flame retardant 15～25
Expanded graphite 6～16
Cenosphere 5～10
Hydroxyethylcellulose 1～4
Calcium carbonate 20～30
Water 8～15
In the above-mentioned material, chlorine partial emulsion, hydroxyethylcellulose, water are as bonding agent; APP is as fire retardant; Expanded graphite, cenosphere are as refractory material; Calcium carbonate is as filler.The refractory material that expanded graphite, cenosphere are lightweight, loosen, have swelliong power in the base can make inclusion unit weight light, and certain air permeability is arranged, and is convenient to the cable heat radiation.During back-fire relief Bao Shouhuo, expanded graphite, cenosphere etc. are under the acting in conjunction of fire retardant, and inclusion expands and forms the low cellular integral body of thermal conductivity factor, can stop flame and flue gas to spread effectively with hole, the tight shutoff in slit.
The material of above-mentioned fire-retardant packaging bag is the low alkali glass fiber cloth or the alkali-free glass fiber cloth of fine mesh.Thick shape pocket as packing inside bag is arranged in fire-retardant packaging bag.The light weight of above-mentioned glass fabric own, chemical stability be good, do not burn, and good heat resistance, softening point temperature be up to 850 ℃, and have certain intensity, is not easy breakage, and the refractory material in can the operative constraint bag is convenient to the back-fire relief bag and is reused.
In sum, the present invention compared with prior art, production technology is simple; Fire endurance height, physicochemical property are good; Easy to install and use, can change, can reuse after tearing open, corrosion-resistant, water-fast, nontoxic, stable performance adapts to various environmental conditions.
The present invention is through the check of national fire-proof construction material quality supervision and test center, and testing result sees Table 1 in detail.
