Description
Technical Field
The invention relates to the technical field of steel structure fireproof coating processing, in particular to a preparation method of a non-expansion type steel structure fireproof coating.
Background
The non-intumescent fire-retardant coating for steel structures (also called thick-type fire-retardant coating for steel structures) is a fire-resistant and heat-insulating material formed by mixing portland cement as a binder with a heat-insulating material. The fireproof coating delays the temperature rise of the protected steel by means of the incombustibility, low thermal conductivity or heat absorptivity of the material in the coating in a fire, and achieves the purpose of prolonging the fire resistance limit of a steel structure, and the fireproof coating does not have obvious volume change before and after the fire.
Most of the non-expansion type steel structure fire-proof coating circulating in the market at present is prepared by taking portland cement as a binder, and mixing with mineral materials such as expanded perlite, expanded vermiculite and the like and auxiliaries. The article "the current situation and development trend of the production process of the steel structure fireproof coating in China" points out: the domestic thick steel structure fireproof paint product is basically powder package, and the material is added with water and stirred for use after being transported to a construction site. The production process is a physical mixing process, the main equipment is a dry powder mixer (production units with small sales volume usually adopt a manual mixing mode), the mixing aim is to uniformly mix the binder and various inorganic light and reinforced materials in a dry state, and the production process is also a core process for producing the thick steel structure fireproof coating. During production, the raw materials which are qualified through inspection are accurately weighed according to the formula, the stirrer is started, the materials are put into the dry powder mixer according to the feeding sequence for mixing, the materials are continuously mixed for a period of time after all the materials are put, and the materials are unloaded, metered and packaged after sampling and inspection are qualified. "
Vermiculite is a complex hydrous aluminosilicate mineral of iron and magnesium. Under a certain temperature, the expanded vermiculite is rapidly expanded to form the expanded vermiculite after a proper time, and the expanded vermiculite has low heat conduction efficiency and good heat insulation performance and fire resistance. Because the expanded vermiculite is a porous lamellar structure and has great water absorption, the increase of the moisture content can cause the air in the gaps of the expanded vermiculite to be replaced by the moisture, so that the heat conductivity coefficient is increased, and the fireproof performance is further influenced.
Perlite is a water-containing vitreous lava ejected from acidic magma and is named because of its pearly fracture structure. When the water-containing glass lava is subjected to high temperature, the water-containing glass lava can soften into a viscous state, and simultaneously, the water in the water-containing glass lava is vaporized into high-pressure steam, so that the glass is expanded to obtain expanded perlite with a porous structure, the porous structure is the reason for forming low thermal conductivity, but the expanded perlite has great water absorption, and the data shows that the weight water absorption of the expanded perlite for 15-30 minutes reaches 400%, and the volume water absorption of the expanded perlite reaches 29-30%. The increase in moisture content also causes the air in the voids of the expanded perlite to be replaced by moisture, resulting in an increase in thermal conductivity and a decrease in fire performance.
Therefore, the core production equipment of the non-intumescent steel structure fireproof coating is only a dry powder mixer, and the key materials playing a heat insulation role after the coating is cured are expanded vermiculite and expanded perlite. The prior production process is to uniformly mix the portland cement, the expanded vermiculite, the expanded perlite and other auxiliary materials by a dry powder mixer. The coating produced by the process is easy to absorb moisture after being cured into a coating.
In the national standard GB14907-2018 Steel Structure fire-retardant coating implemented in 2019, the change of the fire-resistant time of the coating after a water-resistant test is considered, and the standard requires that the attenuation of the fire-resistant time cannot be more than 35%. Therefore, water resistance is an important indicator of aqueous intumescent coatings.
The invention patent CN106699052B discloses a thick steel structure fireproof paint and a preparation method thereof, and discloses a production method of the thick steel structure fireproof paint, namely, cement binder, fly ash, calcium carbonate, refractory clay, water retention agent, air entraining agent, flame retardant, thixotropic agent, fiber and dried expanded perlite are uniformly mixed by a gravity-free horizontal mixer, the stirring speed is 80r/pm, and the stirring time is 8 min.
The invention discloses a fireproof coating for a thick steel structure, and a production method of the fireproof coating for the thick steel structure, which is characterized in that a main adhesive, an auxiliary adhesive and reinforcing fibers are added into a gravity-free stirrer, a fly cutter is opened to avoid adhesion and prevent uneven stirring, the stirring time is 3 minutes, the fly cutter is closed, a flame retardant and other additives are added, stirring is continued for 3 minutes, fireproof filler is added, and stirring is continued for the following time: and 2 minutes, metering, packaging and discharging.
The invention discloses a production process of a WH outdoor thick steel structure fireproof coating, which is disclosed by CN104231706A and comprises the steps of putting powder and an auxiliary agent into a stirrer for stirring, after the stirring is finished, sieving the powder and the auxiliary agent, carrying out the next weighing operation on the qualified powder, returning the unqualified powder into the stirrer for re-stirring, and after the weighing is finished, bagging and warehousing the qualified powder.
The existing production method of physical normal temperature mixing is suitable for a formula of adding a powder waterproof agent to improve the hydrophobicity of a cured coating, the hydrophobic agent finally migrates to the surface of the coating, nonpolar groups of the hydrophobic agent are mutually close and associated to generate a hydrophobic effect, but the hydrophobic agent cannot form a continuous hydrophobic barrier because the surface of the fireproof coating rich in the heat insulation aggregate is rough. On the other hand, for dry powder products, the problem of moisture absorption of the dry powder cannot be avoided because the heat insulation aggregate has water absorption, and the water absorption cannot be improved by the physically added hydrophobic agent. Therefore, the method for adding the hydrophobic agent does not obviously improve the hydrophobicity of the coating of the non-intumescent steel structure fireproof coating, the coating obtained after the coating is cured cannot meet the requirement of attenuation after a new standard GB14907-2018 water resistance test, and the method is not suitable for the formula and the technical requirement of preparing the intrinsic hydrophobic steel structure fireproof coating by coating the liquid hydrophobic modifier.

Compared with the prior art, the invention has the beneficial effects that:
according to the invention, the coupling agent is grafted to the surface of the heat-insulating aggregate, so that the non-intumescent fire-retardant coating body is endowed with hydrophobicity, and compared with the external addition type non-intumescent steel structure fire-retardant coating added with the organosilicon hydrophobic agent, the hydrophobicity of the coating is greatly improved.
The preparation method of the intrinsic hydrophobic non-intumescent steel structure fire retardant coating disclosed by the application is specially used for large-scale production of the intrinsic hydrophobic non-intumescent steel structure fire retardant coating formula. Compared with the hydrophobic non-expansion type steel structure fireproof coating produced by the traditional normal temperature mixing equipment, the product produced by adopting the formula and the preparation method of the intrinsic hydrophobic non-expansion type steel structure fireproof coating has more excellent hydrophobicity, and can not reduce the falling caused by the water absorption weight increment and repeated freeze thawing of the coating after long-term use, and the excellent light anti-falling steel structure fireproof coating can be obtained by the process.
In particular, the method comprises the following steps of,
(1) the vitrified micro bubbles and the aerogel particles have the excellent characteristics of light weight and fire resistance, the heat conductivity coefficient of the vitrified micro bubbles is 0.032-0.045 w/m.k, and the heat conductivity coefficient of the aerogel particles is lower and ranges from 0.013-0.025 w/m.k. When the heat-insulating aggregate is added into the cement cementing material in a proper proportion, the steel structure fireproof coating which is light in weight, fireproof and has certain compressive strength and bonding strength is formed. The addition of the refractory fibers can improve coating cracking caused by the failure of cement to effectively bond a large amount of insulation aggregate and volume shrinkage during drying. The powdery flame retardants such as light calcium carbonate, heavy calcium carbonate, magnesium hydroxide and aluminum hydroxide have an auxiliary bonding effect with slurry formed by water in the cement hydration process, and can be decomposed to absorb heat when a coating is fired, and decomposition products of the powdery flame retardants can close ablation holes on the surface of the coating, so that the ablation resistance of the coating is enhanced when the coating is fired. The selection of the auxiliary agent is mainly considered from the aspects of improving the production, storage and construction performance of materials and the protection of the coating after construction, and the auxiliary agent does not help to improve the fire resistance of the coating.
(2) The component B has low viscosity and surface tension and high wetting ability, has small contact angle with the heat-insulating aggregate consisting of the vitrified micro bubbles and aerogel particles, and can be spread on the surface of the heat-insulating aggregate quickly. Meanwhile, the surfaces of the heat-insulating aggregates are rich in hydroxyl, so that the silicon hydroxyl at one end of the silane coupling agent which is hydrolyzed in the component B of the modifier is oriented to the surfaces of the heat-insulating aggregates and is subjected to hydrolytic polycondensation with the hydroxyl on the surfaces of the materials to form a firm covalent bond. And finally, grafting a hydrophobic chain segment on the surface of the heat insulation aggregate so as to endow the heat insulation aggregate with intrinsic hydrophobic property.
(3) The refractory fiber sepiolite wool is hydrated magnesium silicate, the surface of the refractory fiber sepiolite wool is also rich in hydroxyl, and a hydrophobic chain segment can be grafted through a covalent bond under the action of the component B, so that the sepiolite is endowed with intrinsic hydrophobicity.
(4) The chemical flame retardants such as light calcium carbonate, heavy calcium carbonate, magnesium hydroxide, aluminum hydroxide and the like and brucite fiber have no free hydroxyl or only contain a small amount of hydroxyl on the surface, and can not form a grafted hydrophobic structure connected by covalent bonds with the component B. However, since a polymeric film of a silane coupling agent is formed on the surface of these materials to form a physical hydrophobic film, these materials are also imparted with intrinsic hydrophobicity.
(5) After the action of the component B, the materials except the cement have intrinsic hydrophobicity. In order to achieve the aim of making the cement hydration product self-hydrophobic, the invention also creatively introduces a crystallization master batch, and an active compound contained in the material can permeate into the gaps of the internal structure of the cement after the cement hydration product and water act simultaneously, and the permeated active compound and free calcium oxide in the cement are subjected to an interactive reaction to generate dendritic fiber crystals (silicone calcium crystalline calcium sulphoaluminate and the like) which are insoluble in water. So that a compact impervious area is gradually formed on the surface layer of the cement towards the depth, and the impervious capability of the cement cured product is greatly improved.
(6) The production is simple and convenient, coupling agent hydrolysate is used as a modifier, and the modifier forms a primary hydrophobic coating layer on the surfaces of the original water-absorbing heat-insulating aggregate, the fire-resistant fiber and the fire-retardant powder through chemical bonds or physical action. The steel structure fireproof coating with excellent hydrophobic performance is formed, and the whole process can be carried out in the intrinsic hydrophobic non-expansion type steel structure fireproof coating equipment.

TABLE 1 fire-retardant coating for intrinsic hydrophobic non-expansion type steel structure
After the intrinsic hydrophobic non-expansion type steel structure fireproof coating obtained by the processing and production of the process is constructed and cured, the intrinsic hydrophobic non-expansion type steel structure fireproof coating has more excellent hydrophobic performance than a non-expansion type steel structure fireproof coating added with a hydrophobic agent, can resist water vapor corrosion in the atmosphere, and effectively slows down freeze-thaw disintegration, alkali-aggregate reaction, sulfate corrosion, carbonization and corrosion damage of a bottom layer matrix (such as steel) caused by water vapor invasion.
