Abstract
Expansible fireproof decorative coating for steel structure of the present invention is the frie retardant coating that is used for the exposed steel construction supporting member of Industrial buildings and covil construction.It is made up of base-material, fire retardant, inorganic flame-proofing matter and strongthener and pigment.It is main base-material that this coating adopts the organic polymer emulsion, and water is thinner and solvent, makes stopping composition and whitening agent with light inorganic body refractory body.This coating is thin, is generally 4 mm thick, expansion 16-40 millimeter when meeting fire or high temperature, and fire-resistant is more than one hour.This coating material production, easy construction, no obnoxious flavour volatilization, weathering resistance, water-tolerant, strong adhesion, good decorating effect.
Description
Steel knot expansible fireproof decorative coating of the present invention is the frie retardant coating that is used for the exposed steel construction supporting member of Industrial buildings and covil construction.
Expansible fireproof decorative coating for steel structure is different with the steel structure fireproofing thermal insulating coating, the former is because coating is coated with thin, decorative effect is preferably arranged, mainly be used in the steel construction surface of exposed fire endurance about one hour, play fire prevention and decoration function, latter's thick coating, good heat-insulation effect, but coatingsurface is coarse, intensity is relatively poor, mainly is used on the demanding hidden steel construction supporting member of fire endurance.
Expansible fireproof decorative coating for steel structure and timber structure fire-proof dilatation are also inequality.The former works to improve the member fire endurance in fire process, the latter rises fire-retardantly at the fire initial stage, prevent the effect that base material catches fire rapidly.
Expansible fireproof decorative coating for steel structure still occurs at home for the first time; Abroad, countries such as the steel expansion of fire retardant coating such as the U.S., Britain, Australia's land productivity are all widely-used, but it is rare to have the steel expansion of fire retardant coating of decoration function simultaneously.China's Beijing Kun Lun Hotel is bought 50 steel expansion of fire retardant coating from the U.S. and is used, and this coating is made solvent with dimethylbenzene, and glass fibre is made strongthener, is coated with interlayer and also lays refractory glass fiber cloth.
The objective of the invention is in order to improve the fire endurance of exposed steel supporting part, the dual function that plays fire prevention and decorate.
This coating principal feature:
(1) prescription is novel: adopting the organic polymer emulsion is main base-material, and water is thinner and solvent, makes stopping composition and toughener with light inorganic body refractory body.
(2) coating is thin: general coating is 4 mm thick, expansion 16-40 millimeter when meeting fire or high temperature, and fire-resistant is more than 1 hour.
(3) well ornamental arranged: can be mixed with the required shades of colour of architectural design.Appearance of coat is smooth, color can satisfy user's requirement.
(4) production, easy construction do not have harmful gas volatilization, use complete.
(5) weathering resistance, resistivity against fire are good, through in the open repeatedly rain-out soak and do not come off on continuing attached to steel substrate.
(6) strong adhesion, anti-bending and anti-vibration.
(7) density is little: wet density is all little than external similar coating with unit dry weight.

Emulsifying agent 0.6-3
Defoamer
6, solvent and thinner tap water 20-30
The expansible fireproof decorative coating for steel structure compound method is as follows:
The prescription of A, slurry:
Chemical assistant and water added mixedly in the container fully stir, add the expanding fire retardant solid powder then, disperseed about 15-30 minute, enter the fineness of shredder circular grinding to 60 micron again, dispersed with stirring, the storage vat of packing into the high-speed stirring dispersion machine.
Technical process:
Liquid additive adds shredder
-stir--
Stir Give dispersion--storage vat
The tap water fire retardant grinds and disperses
The preparation of B, investment precoat
The slurry of A preparation is mixed in proportion with base-material and fully after the dispersed with stirring, with the filtration of 120 mesh sieves, the plastic tank of packing into.Pei Zhi investment precoat is the i.e. whites of true qualities like this.As other color of need, when preparation, add the colored pigment slurry, the even after-filtration of dispersed with stirring gets final product.
The preparation of C, priming paint
The slurry of A preparation is added emulsion in proportion, add again inorganic fire-resistant strongthener together dispersed with stirring form the plastic tank of packing into.In case of necessity, add yellow slurry in the process for preparation, promptly be yellow.
Technical process:
Emulsion-strongthener-stirring-refractory materials-stirring-slurry-stir-sieve-pack.
The technical feature of expansible fireproof decorative coating for steel structure
(1), fire resistance
Test method title: GN 15-82 beam slab and non-bearing building slab fire testing
Method.
