Abstract
The invention provides a preparation method of a steel structure fireproof paint by taking expanded and vitrified small ball as a base material, which is characterized in that on the basis of a traditional organic inorganic clad steel structure fireproof paint, and expanded and vitrified small ball and phenolic resin are used for obtaining the steel structure fireproof paint with excellent performance. According to the invention, expanded and vitrified small ball in the inorganic component replace a traditional lightweight aggregate, thereby the paint has the advantages of low density, high strength, stable physical and chemical performance, and has excellent performances of aging resistance and weatherability, heat insulation, fire resistance, sound insulation and insulation; phenolic resins can replace a traditional film forming agent in the organic component, no fire retardant is applied, so that the coating has the advantages of difficult combustion, good heat stability, low smoke, low toxicity, high mechanical strength, and strong anti-corrosion capability and weather resistance. The paint overcomes the disadvantages of poor flame resistance and toxic flue gas release due to thermal decomposition of the common organic resin.
Description
Technical field
The present invention relates to the technical field of steel structure fire-proof paint, specifically, relating to a kind of is the preparation method of the steel structure fire-proof paint of base material with the expanded and vitrified small ball.
Background technology
Steelwork has from heavy and light, installs easily, short construction period, manufacturing and installation mechanization degree advantages of higher, has received the favor of building trade, at individual layer; Multilayer, skyscraper, factory building; Storehouse, waiting room, buildings such as boarding lounge are used widely; Especially along with the propelling of housing industrialization, Lightweight Steel Construction will be more widely used.Yet steelwork exists fatal defective: fire performance is poor, its mechanical property, and for example supporting capacity, yield-point, tension and Young's modulus sharply reduce along with the rising of temperature.Common iron intensity in the time of 300-400 ℃ begins rapid decline; Its intensity is reduced to original 40%-50% during to 500 ℃.The critical temperature that loses static equilibrium stability at the common iron under the full load situation is about 540 ℃.Under the fire condition, there is not the steelwork of resist about 15 minutes, just to begin to have lost gradually weight capacity.
The main method that solves this defective of steelwork has: frie retardant coating protection, fire-proof board protection, concrete fireproof protection, the interior water flowing cooling of structure etc.Because advantages such as construction are comparatively simple, flameproof effect is comparatively remarkable, economic performance is comparatively reasonable, the kind selectivity is wide, the frie retardant coating protection is to use scheme the most widely.
At present, frie retardant coating roughly can divide inorganic fireproof coating and organic fire prevention coating and fire proof organic-inorganic composite paint.Wherein the inorganic fireproof coating component generally has: bond, as: cement, water glass, phosphoric acid salt, calcined kaolin, gypsum, Natural manganese dioxide, sal epsom, wilkinite; Color stuffing, as: pearlstone, expanded vermiculite, float pearl, cenosphere, lime carbonate, silica powder, sepiolite powder, talcum powder; Strongthener, as: spun glass, steel fiber, aluminum silicate fiber; Fire retardant, as: various oxyhydroxide, kernite, ammonium polyphosphate.The ubiquitous shortcoming of this type frie retardant coating is cohesiveness and poor water resistance, is prone to be full of cracks, efflorescence, peels off, and coating density is big, and construction is inconvenience comparatively, and coating decoration property is not good.
The component of organic fire prevention coating generally has: membrane-forming agent, as: vinyl resin, bromocarbon acrylic acid resin, bromine carbon tube/epoxy resin, fluorocarbon resin, organosiloxane resins; Fire proofing additive, as: ammonium polyphosphate, ammonium polyphosphate, ammonium hydrogen phosphate, tetramethylolmethane, NSC 65881, hydroxy resin; Whipping agent, as: trimeric cyanamide, melamine phosphate, Dyhard RU 100, clorafin, ammonium phosphate salt, aminoresin; Inorganic color stuffing, as: white titanium pigment, zinc oxide, kaolin, sepiolite powder, talcum powder; Skimmer and flow agent.Yet steel structure fire-proof paint organic and that organic-inorganic is compound exists at present: the fire line of organic polymer itself is poor, even burning; The organic polymer material decomposes produces a large amount of poisonous and harmful flue gases; The fire retardant that adopts decomposites the poisonous and harmful flue gas after being heated; The work-ing life of coating is short etc.
Summary of the invention
Main purpose of the present invention is to solve cohesiveness, the poor water resistance that present inorganic steel structure fire-proof paint exists; Ornamental not good and organic type of steel structure fire-proof paint flameproof effect is poor; Work-ing life, weak point, not environmental protection, decomposes can produce the problem of a large amount of poisonous and harmful flue gases, provided a kind of and had thermal insulation, fire prevention, low cigarette, low toxicity, lightweight, tool high-strength, competent excellent performance is ornamental is the preparation method of the steel structure fire-proof paint of base material with the expanded and vitrified small ball.
