Abstract
A thick section steel structure fireproof coating is characterized in that the thick section steel structure fireproof coating is composed of a fireproof coating, a binder and water according to a weight ratio of 1:0.08:1.2. The NH-AWS indoor thick section steel structure fireproof coating is a water-soluble coating, is prepared by compounding the inorganic binder with many flame-retardant heat insulation coatings, and a coat formed by the thick section steel structure fireproof coating can form a heat insulation layer after meeting fire, so a steel member is insulated and protected from heat in a fire hazard, and does not generate any harmful gases at a high temperature, and the strength of the steel member does not acutely decrease under the action of the high temperature of the fire hazard, thereby the collapse of buildings is avoided; and the NH-AWS indoor thick section steel structure fireproof coating has the advantages of high binding strength, excellent water resistance, good weather ability, light specific gravity, long fireproof time, and suitableness for the fireproof protection of the naked parts of steel structure buildings with high fireproof limit.
Description
technical fieldthe present invention relates to a kind of steel structure frie retardant coating, be specially a kind of thick formed steel construction frie retardant coating and construction technology thereof.
Background technology
Along with social development, the improving constantly of people's living standard, the especially develop rapidly of industrial economy, people's material life and economic life are all greatly improved.
Along with the development of process of industrialization; especially in the middle of the construction of large-and-medium size cities; steel construction is with its superiority of constructing quickly and easily; become a very important Application in Building material; build and establish as the steel of metal material; be applied to the places such as Standard Factory Room, large-scale stadium, airport, bridge, multi-storied garage more; in order to ensure that it withstands scrubbing and fire performance of being exposed to the sun of the sun, wind and rain for a long time, conventionally can be anticorrosion in steel structure surface brushing, frie retardant coating to be to ensure its weather resisteant and resistivity against fire.
The material on existing steel structure surface mostly is simple brushing or spraying, only can play some weatherproof effects, and together with the steel structure of brushing frie retardant coating cannot well cement in topcoating, work-ing life is short.
Therefore, provide one steel structure fire-proof paint and steel construction basic unit well can be combined, make its life-span long, the steel structure fire-proof paint construction technology that adhesive property is good, has been a problem of needing solution badly.
Summary of the invention
In order to overcome above-mentioned deficiency of the prior art; the invention provides one can well combine steel structure fireproofing material and steel construction basic unit; and long service life, adhesive property is good, the steel structure fire-proof paint construction technology that steel construction is played a very good protection.
A kind of thick formed steel construction frie retardant coating, is characterized in that, is combined: frie retardant coating: binding agent: water=1:0.08:1.2 by following raw materials according according to weight proportion;
Described frie retardant coating is: the indoor thick formed steel construction frie retardant coating of NH-AWS;
Described binding agent be VAE acetic acid second rare-ethylene copolymerization emulsions;
A kind of thick formed steel construction frie retardant coating, its construction technology step is as follows:
Before a, frie retardant coating construction, prepare:
1) steel structure surface need carry out rotproofing and rust-inhibiting paint is done solid work;
2) steel component surface dust, impurity, greasy dirt should thoroughly be removed totally, require the cleaning of steel component surface without greasy dirt, dust;
B, primary coat construction:
For making the indoor thick formed steel construction frie retardant coating of NH-AWS and steel member bonding firmly, before applying, frie retardant coating should carry out interfacial agents spraying, concrete operations are: first adopt the method for roller coat or spraying in the even brushing interfacial agents of steel component surface, at the uncured front spray coated flame retardant coarse aggregate of interfacial agents, so that steel component surface forms uneven surface, strengthen the cohesive strength of frie retardant coating and steel member base material, after interfacial agents is done solid work, then carry out surface construction.
C, face are coated with construction technology:
1) after having constructed, primary coat carries out the spraying application of surface layer frie retardant coating;
2) frie retardant coating: binding agent: water=1:0.08:1.2 carries out proportioning according to weight ratio,
3) feeding sequence: after according to the above ratio material being measured, first binding agent and water are poured in container and stirred, churning time is 1min, then adds the indoor thick formed steel construction frie retardant coating of frie retardant coating powder NH-AWS;
4) adopt agitator to stir, churning time is controlled at 5min and is advisable, must not overlong time, and to prevent from destroying the granularity of coating.
5) coating decoration
(1) application can adopt spraying, trowelling or its constructional method combining;
(2) while adopting spraying, spray gun will be perpendicular to by spray steel member, and apart from moderate, spraying air pressure should keep 0.4～0.6MPa;
(3) spraying application should divide all over completing, and each is preferably 5mm all over application thickness, after must or solidifying at last time substantially dry, then sprays latter one time.Construction thickness is as the criterion to meet design requirement, and smear the timed interval is 8h at every turn, and temperature can appropriately adjust when different;
(4) while spraying, should detect coat-thickness with thickness measuring pin at any time, ensure to meet the technical requirements of fire protection design specification, guarantee to reach the fire resistance period of design.
D, maintenance:
The complete maintenance of should sprinkling water immediately after coating initial set of constructing, curing time is not less than 10 days.Maintenance should adopt the relevant devices such as atomizer to carry out atomization watering maintenance.
The quartz sand that described fire-retardant coarse aggregate is 2-4mm, must be evenly in the time of spraying, can not occur stream pendant phenomenon.Fire-retardant coarse aggregate consumption is 2.5Kg/ ㎡;
Described interfacial agents is acrylic resin, and consumption is 0.25Kg/ ㎡;
actively beneficial effect:the indoor thick formed steel construction frie retardant coating of NH-AWS of the present invention is water soluble paint, with mineral binder bond and multiple flame resistant heat insulation material is composite forms, coating is met fire can form thermofin, make steel member in fire, be subject to thermal insulation protection, when high temperature, can not produce any obnoxious flavour, its intensity can sharply not decline and cause buildings to collapse under the high temperature action of fire; The indoor thick formed steel construction frie retardant coating cohesive strength of NH-AWS is high, has excellent water-resistance, and weather resisteant can be good, light specific gravity, and fire resistance period is long, is applicable to the steel construction exposed part flameproof protection that fire endurance is high.
