Abstract
The invention discloses a waterproof and fireproof inorganic blocking material which is prepared by mixing the following raw materials with the parts by weight: 40-56 parts of construction gypsum, 0-20 parts of grade I fly ash or grade II fly ash, 24-40 parts of fine mineral powder and common Portland cement, 0-1 part of methyl cellulose ether, 0-3 parts of calcium stearate or zinc stearate or the mixture thereof, 0-0.1 part of citric acid monohydrate, 0-300 parts of quartz sand, 0-75 parts of vitrified micro bead and 0-75 parts of expanded vermiculite. The waterproof and fireproof inorganic blocking material of the invention has the advantages of superior waterproof and fireproof performance, fast coagulating and hardening speed, quick increase in early strength, moderate later strength, convenient disassembly, simple construction, immediate use after being mixed, free adjustment of coagulating time, convenient storage and transportation, environmental protection, etc.
Description
Technical field
The present invention relates to a kind of waterproof fireproofing inorganic plugging material, be specifically related to the plugging material that a kind of power plant, power station, cable trench, cable tunnel fire-retardant fireproof waterproof use, the waterproof fireproofing material of particularly shutoff penetrability opening.
Background technology
Buildings leaves the aperture and the building slit of a large amount of cable through holes and air conditioner pipeline, anti-smoke discharging pipe, heat distribution pipeline between floor and body of wall in construction and use.In case presence of fire, flame and toxic gas can spread to contiguous place by these apertures and slit, and pipelines such as while cable gallery also may form the vertical shaft effect, thereby have quickened the expansion of fire, have increased difficulty for putting out a fire to save life and property of fire.Therefore, shutoff is carried out in these apertures and slit, improved the fire performance of building partition member, enlarge significant the fire preventing accident.
At present, on the market there be the material of fireproof blocking commonly used: types such as inorganic fireproofing plugging, organic fire prevention calking, fire-resistant bag.Wherein inorganic fireproofing plugging is specially adapted to perforated holes such as pipeline or electric wire, and especially to the shutoff of bigger hole, floor gap hole, effect is better.
Tradition exists setting and harden slow based on the inorganic fireproofing plugging of ordinary Portland cement, early strength increases slow, later strength is too high again, be unfavorable for dismounting, problems such as fire resistance difference, material fire-proof and water-proof inorganic plugging material of the present invention, compare based on the inorganic fireproofing plugging of ordinary Portland cement with tradition, have fast solidifying, early strength increases rapidly, just can reach 50% after general 2 hours, later strength is moderate, is convenient to remove, and construction is simple, with mixing, advantage such as can arbitrarily adjust time of coagulation with usefulness.
Summary of the invention
It is slow based on the setting and harden of the inorganic fireproofing plugging of ordinary Portland cement that purpose of the present invention is intended to solve tradition, and early strength increases slow, and later strength is too high again, be unfavorable for dismounting, problems such as fire resistance difference provide a kind of fire resistance superior, fast solidifying, early strength increases rapidly, later strength is moderate, is convenient to remove, and construction is simple, with mixing with usefulness the waterproof fireproofing inorganic plugging material that can arbitrarily adjust time of coagulation.
Waterproof fireproofing inorganic plugging material of the present invention is become by the mixed raw material of following weight part: plaster of Paris 40～56; I level or II level flyash 0～20; ground blast furnace slag and ordinary Portland cement 24～40; methyl cellulose ether 0～1; calcium stearate or Zinic stearas or their mixture 0～3, Citric acid monohydrate Food grade 0～0.1, quartz sand 0～300; glass bead 0～75, expanded vermiculite 0～75.
The mixed raw material that waterproof fireproofing inorganic plugging material of the present invention is preferably as follows weight part becomes: plaster of Paris 56; I level or II level flyash 20; ground blast furnace slag and ordinary Portland cement 24; methyl cellulose ether 1; calcium stearate or Zinic stearas or their mixture 3, Citric acid monohydrate Food grade 0.1, quartz sand 150; glass bead 75, expanded vermiculite 75.
Preparation method of the present invention: this inorganic fire waterproof putty according to the accurate weighing of prescription after, the thorough mixing packing bag of packing into after evenly gets final product in mixing machine.
It is main adhesives that the present invention selects plaster of Paris for use; be equipped with hydraulic cementing materials such as an amount of ground blast furnace slag and cement; achieve the intensity and the waterproof fireproofing performance of inorganic fire waterproof putty of the present invention; and and behind the rational proportions such as inorganic non-combustible weighting material such as quartz sand, glass bead, expanded vermiculite; the fire resistance that not only has itself; can also bring into play synergisticing performance, improve the coefficient of softening of material, thereby improve water resistance.And according to the time of coagulation of regulating this inorganic fire water-proof material by the volume of regulating Citric acid monohydrate Food grade, the volume difference of the different Citric acid monohydrate Food grades of filling a prescription.In addition, adopt calcium stearate or Zinic stearas or their mixture to reduce dry strength, improve coefficient of softening.
Using method of the present invention: the best construction temperature of this fire-proof and water-proof inorganic plugging material is 0～40 ℃, before construction, earlier with around the object or cable surface clean out, in hole bottom or passage, set the mould that needs size again, putty runs off when preventing to pour into a mould.During cast, the putty of the dry powder that mixes is poured in the clean container, added water and stir, be injected in the mould and get final product.
The airtight packaging bags of application was placed on the cool place well after product mixed by proportioning, deposit at dry place, prevented to make moist.
Main consolidating material among the present invention is a gypsum, hydration rate is fast, can basic aquation finish in 24 hours, the intensity of gypsum is constant substantially after 24 hours, cement and the breeze in the consolidating material depended in the increase of later strength of the present invention, because of volume less relatively, so that later strength of the present invention increases is few; And gypsum can discharge water vapour and reduce surface temperature when meeting fire burns, have good flame-retardant effect.
Beneficial effect of the present invention: the waterproof fireproofing inorganic plugging material of dry powder type of the present invention has the waterproof fireproofing superior performance, fast solidifying, early strength increases rapidly, later strength is moderate, be convenient to remove, construction is simple, with mixing with usefulness, can arbitrarily adjust time of coagulation, store convenient transportation, characteristics such as environmental protection detect every index through construction quality inspection center of Jiangsu Province's building materials institute and all satisfy regulation among the industry standards of public safety GA161-1997 of the People's Republic of China (PRC) " performance requriements of fire-proof sealing material and test method ".
Materials used of the present invention is commercially available getting.
