Delay the temperature rise of steel, effectively protect steel beam column.Superthin expansion steel structure fireproof coating construction can use spraying, brushing or
Roller coat, is generally used on fire endurance requirement construction steel structure within 2 h.Occur in that fire resistance meets or exceeds
The super-thin steel structure fire-proof paint new varieties of 2 h, it is mainly with polymethacrylates or the epoxy resin of special construction
Compounding with amino resins, chlorinated paraffin etc. as base material binding agent, it is accompanied by high polymerization degree APP, Bis(pentaerythritol), trimerization
Cyanamides etc. are fire protection flame retarding system, add the inorganic fire proof material such as titanium dioxide, wollastonite, with 200# solvent naphtha for solvent is compound
Become.Various lightweight steel constructions, rack etc. uses the type fireproof coating to carry out flameproof protection.Owing to such fireproof paint coating surpasses
Thin so that usage amount thicker type, thin section steel structure fire-resisting paint greatly reduce, thus reduce engineering total cost, make again steel tie
Structure has obtained effective flameproof protection, and flameproof effect is fine.
Described thin coated type steel structure fire-proof paint refers to that coating layer thickness is more than 3mm, less than or equal to 7 mm, has and necessarily decorates effect
Really, expand during high temperature and thicken, fire endurance fire-resistant coating for steel structure within 2 h.This kind of fire-resistant coating for steel structure is usually
Making base material with suitable waterborne polymeric, then be equipped with the compositions such as fire retardant compound system, fire-proof additive, refractory fibre, it is prevented
Fire principle is with ultrathin.To this kind of fireproof coating, it is desirable to the waterborne polymeric of selection steel substrate must be had good adhesive force,
Durability and resistance to water.Its dicoration is better than thicker fireproof coating, is inferior to super-thin steel structure fire-proof paint, general fire-resistant pole
Limit is within 2 h.Therefore it is commonly used in the steel structure fireproof protection engineering less than 2 h fire endurances, frequently with spraying application.?
One period occupies the biggest ratio, but along with the appearance of super-thin steel structure fire-proof paint, its market share is gradually substituted.
In the present embodiment, described thicker fire-resistant coating for steel structure refers to that coating layer thickness is more than 7 mm, less than or equal to 45 mm,
Face in pelletized form, density is less, and thermal conductivity is low, and fire endurance is at the fire-resistant coating for steel structure of 2 more than h.Due to thicker fireproof coating
Composition mostly be inorganic material, therefore its fire protecting performance is stable, and permanence operation is preferable, but the granule of its coating composition is relatively
Greatly, appearance of coat out-of-flatness, the overall appearance of impact building, therefore it is mostly used for structure concealed work.Such fireproof coating exists
Utilizing material granular surface in fire, density is less, and thermal conductivity is low or the heat absorptivity of material in coating, has delayed the temperature of steel
Rise, protect steel.This kind of fireproof coating is (such as waterglass, Ludox, phosphalugel, fire-resistant water with suitable inorganic binder
Mud etc.), then be equipped with inorganic light weight thermal insulation aggregate materials (such as expanded perlite, expanded vermiculite, Hai Baoshi, floating bead, flyash etc.),
Fire-proof additive, chemical agent and reinforcing material (such as alumina silicate fibre, rock wool, ceramic fibre, glass fibre etc.) and filler etc.
Mixed preparing forms, and has lower-cost advantage.Construction is frequently with spraying, it is adaptable to fire endurance requires 2 more than h's
The hidden steel construction of indoor and outdoor, high-rise full steel structure and multi storied factory building steel construction.As: the post of high-rise civil building, general industry with
The fire endurance of the post supporting multilamellar in civil buildings all should reach 3 h, and this thicker fireproof coating need to be used to protect.
In the present embodiment, described mineral wool class Building Fire Protection insulating moulding coating is thick coated type architectural fireproof paint Margarita of continuing
Series of rocks arrange, the another important fireproof coating series after magnesia oxychloride cement series fireproof coating, still belong to blank, it and perlite class
Fireproof coating is compared, and it is mainly characterized by the mineral fibres as thermal insulating filling can play potentiation to strength of coating, can answer
The area multiple for earthquake or the building often shaken, and fire prevention, heat insulation, the effect of sound-absorbing can be played.Mineral wool class is built
Building fire-proof and thermal-insulation coating and mainly have mineral fibres fire-proof and thermal-insulation coating, thermal insulating filling, its main component is mineral wool, binding material
It is usually cement, uses dry spraying construction at the scene, reinstate pressure-air carry with binding material one after i.e. fiber is dispersed through
To nozzle, then with the high atomization water mixing jetting being distributed in around spout to surfaces to be coated.It is obtained in that density is less
Coating, it is thus possible to alleviate the weight of whole building, reduces building loading.Abroad it is widely used quick-dry type mineral wool class to prevent
Fire coating, when the construction site of execution conditions difference uses, has the advantages such as easy construction, low cost, drying time be short.
