Abstract
An outdoor thick type fireproof coating for steel structure relates to a fireproof coating. Provided are an aluminate cement-based thick type fireproof coating for steel structure with an inorganic mineral thermal insulation combination material as main material, and a manufacturing method of the fireproof coating. The fireproof coating consists of a binder, a modifier, an aggregate and an enhancement material. The manufacturing method comprises sieving and drying the aggregate; pulverizing and sieving sheet-like mica; cutting off and dispersing the enhancement material; and well stirring the raw and auxiliary materials composed of the binder, the modifier, the aggregate and the enhancement material. The ratio of the modifier to each component of the aggregate and the enhancement material can be adjusted to promote full hydration of the aluminate cement binder and formation of a zirconia-containing aluminum silicate fiber interconnection net-like structure, change component viscosity and improve integrity of the coating. At the same time, a large amount of light fireproof components with different particle sizes are adopted to compact the coating and reduce the coating density. In addition, the coating has high adhesiveness, water resistance and flexibility, is free from cracking, falloff, chalking and wetting, and has good adhesion.
Description
Technical field
The present invention relates to outdoor building frie retardant coating field, be specially a kind of outdoor thick formed steel construction frie retardant coating and preparation method.
Background technology
Steelwork is one of main building structure, and particularly some long span buildings, bridge, high level and high-rise building employing steelwork are very good.Though self does not fire steel, not fire-resistant, very easily heat conduction, at high temperature can be heated rapidly loses intensity and is out of shape.The critical temperature of structural steel commonly used is generally 540 ℃, and the building fire fire scene temperature is mostly at 800～1200 ℃.In fire, do not take the temperature of sfgd. steelwork promptly to reach the steel critical temperature in the several minutes, cause its supporting capacity sharply to descend, deform, and then lose supporting capacity, cause partial building or the breaking-up of all collapsing.Therefore, comprise that for the multiple structure of forming by concrete and steel in the Highrise buildings pure steel structure all must prevent fire to handle.Thick formed steel construction frie retardant coating is meant that coat-thickness at 8～50mm, does not expand in fire, the heat absorptivity of material delays the intensification of steel in uninflammability, low heat conductivity or the coating of dependence material, and its fire endurance can reach the coating of 0.5～3h.Domestic have SD-2 type and a TN-LG formed steel construction frie retardant coating, and the UK-6 type of Britain and the AD formed steel construction frie retardant coating of the U.S. are abroad arranged.
Thick formed steel construction frie retardant coating has characteristics such as density is little, thermal conductivity is low, cohesive force is strong, non-corrosive steel material, is particularly suitable for the flameproof protection requirement of superelevation layer steel construction.Mostly this coating is inorganic water soluble paint; General alkali metal silicate salt, the phosphoric acid salts etc. of adopting are as sticker, and its shortcoming is: coating is not water-fast, and is non-moistureproof; Weathering resistance is relatively poor, and is prone to cracking, shedding, is not suitable for the shortcomings such as application and protection of exposed steelwork.
Summary of the invention
Problem to be solved by this invention is, seeking a kind of is main with the heat insulation composition material of inorganic mineral, have high adhesive force, weathering resistance, in fire have good whole property and fire performance, outdoor thick type environmental-protection fireproof coating.
In order to realize above-mentioned technical problem to be solved; The present invention adopts one group of heat insulation composition material (low-expansion coefficient of inorganic mineral; The expanded vermiculite of low heat conductivity, pearlstone, sheet mica, contain zirconium-type aluminum silicate fiber etc.) be aggregate, be that agglutinate is in use allocated an amount of slow setting sticker into the aluminate cement.The present invention through one group of heat insulation composition material of inorganic mineral, changes the globality of coating on the mineral binder bond basis with aluminate cement, realize agglutinating high temperature continuity; Through control contain zirconium-type aluminum silicate proportion of fibers enhancement coating viscosity, make that its deformability is good, the structure sealing, be prone to advantage such as brushing, piece together with containing the modification of zirconium type acid aluminum fiber realization refractory inorganic binder and cement; Through regulating the proportioning of properties-correcting agent and each component of aggregate; Promote aluminate cement bond aquation fully with the formation that contains zirconium-type aluminum silicate fiber cross-linked structure; Change component viscosity; Improve the globality of coating, the light-weight refractory component that adopts a large amount of granularities to differ simultaneously is so that coating is closely knit and reduce coating density.
Description of drawings
Fig. 1 is a preparation flow synoptic diagram of the present invention.
Beneficial effect
The present invention has significantly improved coating cohesiveness, water tolerance and snappiness, reduced easy explosion under coating high-temp or the quenching conditions, come off, easy efflorescence under the normal temperature, make moist, shortcoming such as poor adhesive force.The frie retardant coating of the preparation of the present invention simultaneously has characteristics such as raw material sources enrich and price is low, the preparation is simple, easy to use, be prone to store, cost is low, environmental friendliness is pollution-free.
Embodiment
Below through embodiment the present invention is described further:
At first with pearlstone and expanded vermiculite sieve respectively, drying, particle diameter is controlled at 1～3mm, the white plates mica becomes to make it less than 20 orders with the ball mill powder is pure, contains the zirconium-type aluminum silicate fiber and cuts off dispersion with cutting cotton machine; Again with expanded vermiculite 13.0kg, pearlstone 21.0kg, sheet mica 5.0kg, contain zirconium-type aluminum silicate fiber 3.0kg and 22.5kg aluminate cement, kernite 1.2kg adds stirrer for mixing and stirs, and makes it to be uniformly dispersed.It is qualified to inspect by random samples, the packing encapsulation.
During concrete the construction, powder is added an amount of water stir, churning time is no less than 5 minutes makes it to be the thick shape fluid state that does not have caking.Rare denseness should be with convenient construction, do not trickle, bond and firmly be advisable.Adopt spraying or hand to smear construction, by fire protection requirement, repeatedly layering is smeared.
Product fire performance: coat-thickness 26mm, fire endurance>=195min; Surface drying time: 13.5h; Cohesive strength: 0.34Mpa; Density: 507kg/m
3 Other performance index all meet steel structure fire-proof paint standard GB 14907-2002.
More than show and described basic preparation flow of the present invention, principal character and advantage.The technician of the industry should understand, and the present invention is not restricted to the described embodiments.
