Abstract
The invention discloses a prescription of an intumescent filler for a fireproof package. The prescription disclosed by the invention is obtained by mixing the following components in parts by weight: 6-20 parts of char-forming agent, 6-20 parts of char-forming catalyst, 10-30 parts of foaming agent, 10-30 parts of inorganic reinforcement, 6-15 parts of inorganic filling agent and 15-45 parts of intumescent material. The prescription disclosed by the invention combines with inorganic filler and organic filler and uses the advantages thereof; fire-resistant barrier with a certain thickness and a certain strength can be intumesced and rapidly charred in a short time in fire, and heat is absorbed and non-flammable gases are released during intumescing and charring processes, so as to achieve the purposes of resisting fire, isolating head and isolating smoke. The prescription has high application value.
Description
Technical field
The present invention relates to the fire-retardant material technical field, be specifically related to a kind of expansion fire-proof bag stopping composition prescription.
Background technology
The present invention is applied in the middle of electric power, telecommunications, postal service, chemical industry, industrial and mineral, enterprise, the building at present, the shutoff in formed cavity when cable, oil pipe, airduct, tracheae, metallic conduit etc. run through thing and pass partition wall or interlayer.What the fire prevention bag that has was filled is inorganic fireproofing plugging, and what the fire prevention bag that has was filled is organic fire prevention calking.The stopping composition of inorganic type is difficult to reach country-level standard; The stopping composition of organic type discharges a large amount of obnoxious flavoures easily when fire prevention, the escape personnel is poisoned suffocate.
Summary of the invention
The purpose of this invention is to provide a kind of expansion fire-proof bag stopping composition prescription, combine with inorganic fillings and organic stopping composition, get the advantage of the two.That this expanded polystyrene veneer stopping composition is heated when meeting fire is inflatable in the short period of time, the charing of expanding rapidly forms the back-fire relief barrier of tool certain thickness and intensity, and absorbs heat in the expansion carbonization process, discharge non-flammable gas, reach back-fire relief, heat insulation, every the purpose of cigarette.Can reach country-level fire resistance period 180min.
Above-mentioned purpose of the present invention is achieved by the following technical programs:
A kind of expansion fire-proof bag stopping composition prescription is mixed by following component according to the parts by weight meter: 6 ~ 20 parts of char-forming agents, 6 ~ 20 parts of char forming catalysts, 10 ~ 30 parts of whipping agents, 10 ~ 30 parts of inorganic enhancing bodies, 6 ~ 15 parts of inorganic fillers, 15 ~ 45 parts of expanding materials.
As a kind of optimal technical scheme, described char-forming agent is tetramethylolmethane or many tetramethylolmethanes.
As a kind of optimal technical scheme, described char forming catalyst is poly-phosphate or phosphoric acid salt.
As a kind of optimal technical scheme, described whipping agent is Dyhard RU 100 or trimeric cyanamide.
As a kind of optimal technical scheme, described inorganic enhancing body is flyash.
As a kind of optimal technical scheme, described inorganic filler is aluminium hydroxide or magnesium hydroxide.
As a kind of optimal technical scheme, described expanding material is highly expanded graphite.
As a kind of most preferred technique scheme, expansion fire-proof bag stopping composition prescription of the present invention is mixed by following component according to the parts by weight meter: 10 ~ 14 parts of tetramethylolmethane or many tetramethylolmethanes, 10 ~ 14 parts of poly-phosphate or phosphoric acid salt, 12 ~ 18 parts of Dyhard RU 100 or trimeric cyanamides, 16 ~ 25 parts in flyash, 10 ~ 15 parts of aluminium hydroxide or magnesium hydroxides, 25 ~ 35 parts of highly expanded graphites.
Compared with prior art, the present invention has following beneficial effect:
(1) convenient: as all to be several frequently seen chemical substance, to buy easily and low price;
(2) environmental protection: effective utilization of flyash;
(3) simple: production technique is very simple;
(4) fire resistance period is long: can reach country-level fire resistance period 180min.
(5) expanding volume is big: under the situation of complete expansion, volume increases tens of times.
Embodiment
Further explain the present invention below in conjunction with embodiment, but embodiment does not do any type of restriction to the present invention.
A kind of expansion fire-proof bag stopping composition prescription is made up of following steps:
1. with the per-cent weighing of various packing materials by its weight;
2. various packing materials are ground into powder;
3. in stirrer, stopping composition is stirred;
4. by the specification weighing stopping composition of fire prevention bag, and pack into through special processing, it is sealed in the packing bag the inside that durable glasscloth is made.
Below be embodiment:
Remarks: fire resistance period unit is: minute.
Claims (1)
1. an expansion fire-proof bag stopping composition is characterized in that being mixed by following component according to weight percent meter: tetramethylolmethane 10%, ammonium polyphosphate 15%, trimeric cyanamide 12%, flyash 21%, aluminium hydroxide 12%, highly expanded graphite 30%.
