Abstract
The utility model relates to a graphite intumescent fire retardant coating. Because a high temperature foamed layer in the coating is uniformly provided with an expanded graphite layer and an aqueous resin film layer, the technology deficiencies that conventional coatings will produce large flue are overcome. The fire retardant coating achieves the rapid expansion to form a lightweight carbon layer to retard flame in the fire, does not release toxic gases, and effectively applies the fire protection on base materials. Taking advantage of the self-expanding property by heating of the graphite, the coating is relatively good in durability, so the trouble of fire retardant coating failure in a long time is improved. By using water-based resin film, the cost of the coating is also greatly reduced.
Description
Technical field
The utility model relates to the fire-retardant material technical field, particularly relates to a kind of graphite mould fire-proof dilatation.
Background technology
Along with high stratification, clustered, the development of industrial large-sizedization and the expansion utilization of organic synthesis material of building, coating is with its good protectiveness and ornamentally give comfortable enjoyment, but the combustibility of most of coating and inflammableness have also been brought disaster hidden-trouble.Therefore developing frie retardant coating becomes more and more important to adapt to security against fire.
Frie retardant coating is divided into expanded polystyrene veneer and Non-expansive fireproof paint by its fire prevention form and moiety.Expanding fire-proof paint is domestic most popular coating, can be divided into water-based and solvent borne expanding fire-proof paint two classes, and wherein, Water-borne inflation type refractory coating accounts for more than 75% of coating of expanded polystyrene veneer fire.Aqueous fire-proof coating cost on the domestic market is low, toxicity is low, it is little to pollute, but humidity resistance is relatively poor, is only applicable to use under the dry environment.Although aqueous fire-proof coating possesses above performance simultaneously on the world market, price is surprisingly high, is not suitable for the development need of China market.In addition, existing frie retardant coating adopts ammonium polyphosphate-tetramethylolmethane-trimeric cyanamide (PCN) type flame-retardant system mostly, although the frie retardant coating fire resistance of this flame-retardant system is better, but weather resistance and water tolerance are relatively poor, when in the environment that directly contacts with water or wet environment, using, the phenomenons such as the easy generation of its fire retardant is water-soluble, saltout cause frie retardant coating to lose efficacy, thereby make coating lose fire prevention usefulness.
Steel construction is as the principal mode of modern architecture, and quality is light, intensity is high because having, and anti-seismic performance is good, short construction period, and the building industrialization degree is high, and space availability ratio is large, reduces investment outlay and is widely applied.The metallic corrosion meeting brings huge financial loss, 30% steel is wherein arranged owing to corrosion has been wasted, and steel construction must the brushing protective system, and the steel structure fire-proof paint indispensable material of steel construction that to be state compulsion carry out.
Steel structure fire-proof paint is divided into solvent-borne type and aqueous dispersion type.At present, the anticorrosion protection of steel structure surface is take solvent-borne type as main, the solvent-borne type protective system mainly uses Resins, epoxy, urethane resin, chloride platform thing, the resol etc. of birdsing of the same feather flock together to be the film forming base-material, both at home and abroad the research of the resin binder of watery anti-corrosion paint mainly concentrated on aqueous silicon, fluoropolymer, aqueous epoxy resins and the waterborne polyurethane resin etc., although these resins have good fire resistance, but exist following deficiency: (1) is that oleoresin or water-base resin thermotolerance are all poor, and is at high temperature easily softening; Wherein relative higher resin such as the Resins, epoxy of fire performance will soften when temperature reaches 180～200 ℃, thermooxidizing occurs decompose, in the time of more than 290 ℃, curable epoxide product main chain can rupture, and resol can only anti-250 ℃ temperature, will soften, come off in case surpass; When generally running into fire, scene of a fire heat can reach 400～500 ℃ through the temperature that fireproofing passes to steel construction finish paint surface, use the frie retardant coating of these resins all can't bear high temperature like this and soften, cause fireproofing to come off from the interface of fireproofing and fireproofing bonding, cause big fire directly in the face of steel construction, cause fire prevention to lose efficacy serious threat people's the security of the lives and property; (2) the solvent-borne type protective system is because containing a large amount of organic solvents, and solvent mostly evaporates in construction and dry process, this not only severe contamination environment and endangered health of people, the significant wastage that also resource is caused simultaneously; (3) the resin cost is high; The cost price of Resins, epoxy, urethane resin etc. is high, and use is restricted.
Steel structure fire-proof paint is the steel structure surface that is applied over building and structures, can form the refractory heat-insulating protective layer to improve the coating of Steel Fire Resistance Rating.Classify by the thickness of coating according to GB14907-2002 " steel structure fire-proof paint ", be divided into thick type, slim and ultrathin.Wherein, thick formed steel construction frie retardant coating used thickness is greater than 7mm and is less than or equal to 45mm; general for the building of fire endurance greater than 2 hours; main component is inorganic thermal insulation material; meet fire and do not expand, the heat absorptivity when it utilizes the uninflammability, low thermal conductiv-ity of material self and material breakdown delays the rising of steel temperature; avoid the physical and mechanical property of steel construction to be destroyed, thus the protection steel building.At present, domestic and international research for thick formed steel construction frie retardant coating mainly concentrates on following four kinds: alkali metal silicate salt coating, silicon sol class coating, phosphoric acid salt coating, cement class coating.
In the prior art; anticorrosion about thick formed steel construction; the report of frie retardant coating aspect seldom; " non expansion type steel structure fire retarding anticorrosion paint " that publication number provides for CN1948404A is comprised of the component of following weight part: base-material 50～60; expanded vermiculite 4～8; mica powder 8～12; hollow float bead 6～10; pearlstone 10～15; aluminium dihydrogen tripolyphosphate 8～14; SiO2 modified barium metaborate 6～9, water 105～115, this coating are a kind of non-expansion type dual-function paints for the steel structure fireproofing corrosionproof protection; but this coating is anticorrosion; waterproof effect is poor; reason is to have adopted a large amount of expanded vermiculites and hollow float bead, and the hole between coating system is many, and moisture and air easily enter and pass coating; cause the generation of the corrosion of steel construction liberation of hydrogen and oxygen uptake corrosion, can't effectively anticorrosion and waterproof.Because there are many difficult problems in anticorrosion of steel structure fire prevention, mainly is the problem that both can not take into account, prepare have simultaneously superior anticorrosion and anticorrosion frie retardant coating fire-proof function is very difficult.
Along with the development of national economy, the rapid growth of steel construction output.Steel construction have intensity high, from heavy and light, the series of advantages such as anti-seismic performance is good, construction speed is fast, the structure area occupied is few, industrialization degree is high, be described as one of 21 century " green building ".According to statistics at present Beijing steel building near 40% of gross building area; the steel building area in Recent Years in Beijing every year is about more than 700 ten thousand square metres; from the fire prevention angle; although steel structure member is non-combustible component; but its resistivity against fire is relatively poor; in general, do not add the fire endurance 15min only of the steel construction of protection, the fire performance that therefore improves steel construction is an important step during steel building is promoted.
Frie retardant coating is the method that the most often adopts in China's steel construction protection, probably has the steel construction about 80% to adopt the frie retardant coating protection, and annual steel structure fire-proof paint is more than 30,000 tons in the Beijing Market usage quantity.The expanding fire-proof paint coating expands charing under flame or high temperature, form the nonflammable spongy carbonaceous layer of large tens times even hundreds of times of original thickness of ratio, to cut off extraneous flame to the heating of base material, plays fireproofing function.
Because its coating is thin; still can give prominence to the U.S. on the steel building art after the coating; therefore be widely used in the flameproof protection of industry and covil construction steel construction; but the expanding fire-proof paint that is applied at present steel construction is oil paint basically; can discharge a large amount of organic gass when its construction and burning; can discharge toxic gas and smog when especially meeting fire; greatly increased the danger coefficient when fire occurs; therefore people are making great efforts the development environmental protection coating material always; reduce as far as possible or avoid because producing; environmental pollution and hazard to person that construction or burning cause; the oil paint cost is also high simultaneously, the waste resource.
