Description
Technical field
The present invention relates to fireproof coating field, specifically a kind of highly effective inorganic fire-proof dilatation, it is adaptable to steel knot
The flameproof protection on the surfaces such as structure, nonmetal structure.
Background technology：
Expanding fire-proof paint can effectively prevent as a kind of functional paint or delay fire spreading, with other fire prevention
Material is compared, have the advantages that good thermal insulation, low-density, easily construction, low cost,.Fireproof coating is under conventional sense and common
Decorative coveringn meets fire or at high temperature, the rapid foaming and intumescing of coating forms the heat-insulated carbon with alveolate texture without significant difference
Change layer, so as to prevent or delay transmission of the heat to ground, reach the purpose for the fire endurance for improving ground.
Now widely used fireproof coating mainly has two kinds of systems, and one kind is thicker Non-expansive fireproof paint, mainly
Using cement, rubber powder as main film forming matter, packing type heat-barrier material is added, this fireproof coating mainly uses inorganic material body
System, but fire protection efficiency is low, it is general to reach that 25mm provide 60min refractory protection, such as CN104650626A using thickness
A kind of inorganic fireproof coating.Another fireproof coating system is ultrathin expanding fire-proof paint, and this fireproof coating is organic
System, mainly uses organic resin as film forming matter, expansion type flame retardant is made up of acid source, charcoal source and source of the gas.For example
CN100432167C expanding fire-proof paints, the Main Components of use are organic matter, and the advantage of this fireproof coating is fire prevention
Efficiency high, general 2mm can just provide 60min refractory protection.But the shortcoming of this coating is to use organic system, in construction
A large amount of organic solvents are discharged during use, although running into after flame combustion has in preferable Fire resistances, combustion process
Organic compound combustion produces a large amount of poisonous and harmful flue gases, injury ten of these poisonous and harmful flue gases to personnel when actual fire occurs
Divide danger, there is very big potential safety hazard.Although developing the ultra-thin expansion fireproof coating of environmental type in recent years, use
Water-base resin does film forming matter, a kind of aqueous ultra-thin expansion type fireproof coatings for steel construction of such as patent CN104130671B and
Its preparation method, but water-base resin, expanding fire retardant are still organic-compound system, and expanded foamed system still uses chemistry
Foaming technique, although the discharge of the organic solvent in work progress can be reduced, but organic matter in combustion process can not be solved and fired
Burn the problem of producing a large amount of poisonous and harmful flue gases.
The content of the invention
The present invention provides a kind of ultrathin inorganic expansive fireproof coating, is made up of following raw materials according：
Above-mentioned each component sum meets 100%.
Described waterglass and Ludox provide good adhesive force for coating, simultaneously as the film forming matter of fireproof coating
Participate in fire resistant coating into carbon process.The waterglass is the sodium metasilicate that modulus is between 1.5~3.5, and described Ludox is
Ludox of the pH value between 7-10.
Graphite crystal has the galvanized hexagonal wire mesh plane layer structure being made up of carbon.Carbon atom on layer plane is with strong
Covalent bonding together, and combined between layers with Van der Waals force, with reference to very weak, and interlamellar spacing is larger.Therefore, appropriate
Under conditions of, a variety of chemical substances such as acid, alkali metal, salt can be inserted into graphite layers, and combine to form new change with carbon atom
Learn phase --- compound between graphite layers.This intercalation compound can be decomposed rapidly moment when being heated to proper temperature, be produced big
Gas is measured, graphite is axially expanded into vermiform novel substance, i.e. expanded graphite.This unexpanded graphite layers chemical combination
Thing is exactly expansible graphite.The present invention is used as inorganic expansion agents, moment using the expansible graphite between the mesh of 50 mesh of granularity -300
High-temperature expansion multiplying power is 100-400.
Reinforcing material plays a part of carbon-coating enhancing in expansion carbon layer is formed and improves layer of charcoal adhesive force, root of the present invention
The characteristics of according to system, one kind in glass fibre, ceramic fibre, carbon fiber, silicon carbide fibre, alumina silicate fibre.
Expanded perlite is that perlite ore is preheated, is made under the conditions of TRANSIENT HIGH TEMPERATURE (1000~1300 DEG C) after calcining expansion
Into a kind of inside for alveolate texture white granular material.Its principle is moisture vaporization in perlite ore, soft
That changes contains vitreous ore in sand form internal expansion, forms loose structure.The present invention coordinates expansible graphite using expanded perlite
The foamed char of uniform porous honeycomb structure is collectively forming, each junior unit of porous honeycomb structure includes non-convection air, made
Expanding carbon-coating has compared with low thermal conductivity, trap heat can effectively transmit, prevent flame propagation.
Described inorganic combustion inhibitor includes antimony oxide, aluminium hydroxide, magnesium hydroxide, hydrated magnesium silicate, molybdenum dioxide
In one or more.The back-fire relief ability of coating foamed char can be improved.
To improve the adhesion between inorganic coating and interface, the present invention adds interface cohesion auxiliary agent, solves inorganic coating
The problem of poor adhesive force, ornamental difference, interface cohesion auxiliary agent is dialkyl succinylsuccinate sulfonated ester, diisooctyl succinate sulfonic acid
The sulfonate of salt, fatty acid methyl ester ethoxylate, selected from one kind therein.
Curing accelerator accelerates the curing rate of inorganic coating, adapts to practice of construction and uses, curing accelerator is fluosilicic acid
One kind in sodium, aluminium triphosphate.
The inorganic ultra-thin expansion fireproof coating of the present invention, using waterglass and Ludox as film forming matter, using physics
Foaming technique, the effect of anti-flaming thermal-insulation is reached by inorganic combustion inhibitor and physical blowing agent.Fireproof paint coating thickness of dry film 1-
2mm, can provide at least 60min refractory protection for base material.Present invention VOC free (organic volatile during construction, use
Thing) discharge, do not produce toxic and harmful gas and flue gas during fireproofing function.The use of this fireproof coating can effectively subtract
The harm of small flue gas, is that evacuating personnel and fire fighting and rescue provide more preferable condition, is a kind of green functional coating of safety non-toxic.
