The contribution of the present invention is in that, it efficiently solves the fire safety problem of air-valve.The present invention is by air-valve surface configuration fireprotection layer, and this fire resistant coating forms integral structure with air-valve, both the space carried out needed for external isolation can be saved, possesses again the fire protecting performance of excellence, make the flame baking that air-valve can stand 0.5～3 hour without damaging, thus drastically increase refractory ability and the safety in utilization of air-valve.The fireprotection layer of the present invention can be synchronously performed with the manufacture of air-valve, has the air-valve of fire-proof function thus being formed, and it can directly be installed and used because possessing fire-proof function, and need not time-consuming, construct fire prevention insulating space for air-valve arduously.The air-valve fire resistance of the present invention is reliable and stable, with low cost, and aesthetic property is good, is widely used as and is positioned at corridor furred ceiling or the air-valve near other combustible.
[accompanying drawing explanation]
Fig. 1 is the wind valve structure schematic diagram of the tool fire-proof function of the present invention.
[detailed description of the invention]
The following example is further explanation of the present invention, and the present invention is not constituted any limitation.
The air-valve of the tool fire-proof function of the present invention can be any one in volume damper, air pipe check valve, excess pressure valve or exhaust smoke valve, and the present invention is also unrestricted to the type of air-valve.The embodiment of Fig. 1 has illustrated the structure of the volume damper of the tool fire-proof function of the present invention.
As it is shown in figure 1, be compounded with one layer of fireprotection layer at air-valve 10 outer surface, this fireprotection layer covers the whole outer surface of air-valve.In the present embodiment, described fireprotection layer includes one layer of antirust paint 21 and one layer of fireproof coating 22, and described antirust paint is water-based metal antirust paint, and it is sprayed at the outer surface of air-valve with paint spraying apparatus, and it can effectively suppress corrosion of metal.
For making air-valve 10 possess fire-proof function, with paint spraying apparatus at one layer of fireproof coating 22 of the antirust paint surface spraying sprayed, this fireproof coating must cover whole outer surfaces of air-valve 10, including each edge irregular, this fire resistant coating and air-valve are closely as one, and become a part for air-valve.Described fireproof coating can be thicker fire-resistant coating for steel structure, thin section steel structure fire-resisting paint or super-thin steel structure fire-proof paint.Described fireproof coating can once spray or spray several times; until reaching required thickness; coated fireproof coating is at the fireprotection layer of the outer surface formation flameproof protection of air-valve; heat produced by flame and air-valve can be separated by this fireprotection layer; block flame to stretch inside air-valve; effectively delay the temperature rise of air-valve, thus effectively protecting air-valve.
In embodiments of the invention, described thicker fireproof coating is coating layer thickness is the non-expansion type fire-resistant coating for steel structure of 7～50mm, it is preferable that thickness is 20mm, and its fire endurance is more than 2 hours.The Main Ingredients and Appearance of this thicker fireproof coating is inorganic material, mainly formed by mixed preparing such as inorganic binder, inorganic light weight thermal insulation aggregate materials, fire-proof additive, chemical agent, reinforcing material and fillers, wherein, inorganic binder is waterglass, Ludox, phosphalugel, refractory cement etc., inorganic light weight thermal insulation aggregate materials is expanded perlite, expanded vermiculite, Hai Baoshi, floating bead, flyash etc., and reinforcing material is alumina silicate fibre, rock wool, ceramic fibre, glass fibre etc..Above-mentioned inorganic material can be absorbed heat and thermal conductivity is low, can effectively delay the temperature rise of air-valve steel, to protect air-valve.
In another embodiment of the present invention, described thin section steel structure fire-resisting paint is the coating layer thickness expansion steel-structure fireproofing coating at 3～7mm, it is preferable that thickness is 5mm, and its fire endurance is at 2 hours.This thin section steel structure fire-resisting paint mainly includes by waterborne polymeric, fire retardant compound system, fire-proof additive, refractory fibre etc., and it can be the combination of one or more in transparent fire-resisting paint, water solublity fire-proof dilatation, phenolic aldehyde base fireproof coating, latex fire-proof paint, polyvinyl acetate dairy based fireproof coating, room temperature self-drying type water-solubility expanding fire-proof paint, polyolefin fire-proof insulation coating, modified high chlorine polyethylene fireproof coating, chlorinated rubber fire-proof dilatation, intumescent coating.It the present embodiment is water solublity fire-proof dilatation.This thin section steel structure fire-resisting paint has superior bond strength and weather-proof resistance to water, levelability and good decorative property.When being subject to fire, this fireproof coating can be slowly expanded foamed and form fine and close hard fire proof heat-insulation layer, and this fireprotection layer has very strong flameproofed impact-resistance, can delay the temperature rise of air-valve, thus effectively protecting air-valve.
In another embodiment of the present invention, described super-thin steel structure fire-proof paint is the coating layer thickness fire-resistant coating for steel structure less than 3mm, it is preferable that thickness is 2mm, and its fire endurance is at 2 hours.This super-thin steel structure fire-proof paint is solvent-based system, and it is mainly composited by the polymethacrylates of special construction or the fire protection flame retarding system such as epoxy resin and the base material binding agent such as amino resins, chlorinated paraffin, high polymerization degree APP, Bis(pentaerythritol), tripolycyanamide and the inorganic refractory adding material such as titanium dioxide, wollastonite and solvent wet goods.This super-thin steel structure fire-proof paint can be the combination of one or more in transparent fire-resisting paint, water solublity fire-proof dilatation, phenolic aldehyde base fireproof coating, latex fire-proof paint, polyvinyl acetate dairy based fireproof coating, room temperature self-drying type water-solubility expanding fire-proof paint, polyolefin fire-proof insulation coating, modified high chlorine polyethylene fireproof coating, chlorinated rubber fire-proof dilatation, intumescent coating.It the present embodiment is water solublity fire-proof dilatation.The same thin section steel structure fire-resisting paint of its fireproofing mechanism.
For increasing the aesthetic property of air-valve 10, in the present embodiment, an aspect paint 30 is sprayed at the outer surface of described fireprotection layer with paint spraying apparatus, this finish paint can be the finish paint of known tool decoration function, being varnish in the present embodiment, it constitutes the fire resistant coating of tool fire-proof function together with antirust paint 21, fireproof coating 22.When fire occurs, this fire resistant coating can fire-resistant reach more than two hours, thus can effectively protect air-valve without damage.
Take this, the present invention is by arranging fireprotection layer in conjunction at air-valve 10 outer surface, make this air-valve need not construct fire prevention insulating space and can directly install and use at the construction field (site), thus both met security against fire requirement, space and floor space can be saved again, and fire resistance is reliable and stable, with low cost, aesthetic property is good.
Although the present invention having been disclosed by above example, but protection scope of the present invention is not limited thereto, and when not necessarily departing from present inventive concept, deformation that above each component is done, replacement etc. all will fall in scope of the presently claimed invention.
