The invention discloses a kind of smoke-inhibiting type indoor ultrathin steel structure fireproof coating, the parts by weight composition of each component is：20 35 parts of split resin binder, 25 45 parts of fire proofing additive, 3 10 parts of titanium dioxide, 5 15 parts of suppression cigarette filler, 13 parts of auxiliary agent, 16 28 parts of solvent, while the invention also discloses a kind of preparation technology of smoke-inhibiting type indoor ultrathin steel structure fireproof coating.The present invention is due to having used split resin binder and suppression cigarette filler so that obtained coating not only has very good fire protecting performance, and water resistance and weatherability are also very excellent, and is released almost without toxic irritative gas when meeting fire expansion.
Description
Technical field
The present invention relates to a kind of Novel fire retardant coating, specially a kind of smoke-inhibiting type indoor ultrathin steel structure fireproof coating and
Its preparation technology.
Technical background
Though steel construction is in itself incombustible material, steel construction has the deadly defect of fire resistance difference, in high temperature of fire
Under effect, its mechanical property such as yield strength, elastic modelling quantity, weight bearing power etc. all can drastically decline with the rising of temperature.When
When the heating temperature of steel construction reaches 600 DEG C, steel construction lose substantially whole intensity, rigidity cause excessive deformation and can not be after
It is continuous to use.The temperature in the general scene of a fire reaches 800 DEG C -1000 DEG C, and under such high temperatures, exposed steel construction can go out quickly
Now it is plastically deformed, produces local failure, causing the entirety of steel building will loses weight capacity and collapse within a few minutes,
Cause serious casualty accident and economic loss.Therefore, in order to the fire endurance of steel construction is brought up into design specification regulation
Limit range is, it is necessary to take steel construction measurements for fire-protection, and it is that one kind was both passed through that one layer of fireproof coating is coated on steel construction
The again practical method of Ji, just there is numerous fire-resistant coating for steel structures in the prior art.
But had the following disadvantages and problem in current fireproof coating technology：(1) although the binder resin for using is to coating
Fire protecting performance is increased, but releases a large amount of poisonous irritative gas when meeting fire, and lethal than row very little, big portion is burnt in the scene of a fire
It is all that flue gas is lethal to divide.(2) although prior art notes adding smoke suppressant, graininess smog simply is inhibited, ignores painting
The harmful irritative gas produced in layer expansion process, when particularly fireproof coating is used in low toxicity requirement.
(3) existing low-smoke fireproof coating does not recognize cooperative effect between the two when smoke suppressant and filler is added, and causes fire prevention
The fire protecting performance of coating declines, while durability of coating is poor, even several months internal fissure comes off within 1 year, or changes colour under hygrothermal environment
Jaundice etc..(4) existing fireproof coating is generally thick-slurry type, and viscosity is high to cause workability poor, simultaneously because fineness is too high to cause dress
Decorations unsightly, and do not account for influence of the material fineness to product fire protecting performance.(5) after existing fireproof coating meets fire expansion
The carbon-coating intensity difference of generation, is easily broken through by flame, fire protecting performance decline is not only resulted in, while making scene of a fire flying dust serious.
The content of the invention
To solve prior art fire line, fire resistance, anti-flammability, smoke-suppressing and weatherability deficiency and releasing excitant gas
The defect of body, a kind of smoke-inhibiting type indoor ultrathin steel structure fireproof coating involved in the present invention, it is characterised in that by its former material
The quality parts ratio of material is formulated：25-35 parts of split resin binder, fire proofing additive 27-48 parts, titanium dioxide 3-10 parts, suppression cigarette
Filler 8-15 parts, solvent 15-28 parts and auxiliary agent 1-3 parts.
Further, described split resin binder is acrylic resin, acrylic acid modified alkyd resin and amino resins
Three kinds of mixtures of resin, its weight proportion is acrylic resin：Acrylic acid modified alkyd resin：Amino resins=2:2:1.
Further, described fire proofing additive is made up of dehydration catalyst APP, foaming agent and carbon forming agent, and fire prevention is helped
Agent weight proportion is：APP 45-60%, foaming agent 20-30%, carbon forming agent 18-25%.
Further, the degree of polymerization of described APP is more than 1000；Described foaming agent is melamine or urea
In any one；Described carbon forming agent is any one of pentaerythrite, dipentaerythritol or tripentaerythritol.
Further, described solvent is 200# solvent naphthas or S-150# solvent naphthas or aromatic solvent naphtha S-1000# solvents
Any one.
Further, described titanium dioxide is chloride process rutile type.
Further, described suppression cigarette filler is individually formulated, and suppression cigarette filler is made up of following weight proportion：Three oxygen
Change two antimony 8-25%, zinc oxide 5-10%, talcum powder 10-50%, calcium carbonate 22-65%, perlite 12-30%.
Further, the auxiliary agent includes levelling agent, defoamer and wetting agent.
Further, the levelling agent is type siloxane or esters of acrylic acid.
Further, described levelling agent is BYK306 or AFCONA3777.
Further, the defoamer is type siloxane or silicone
Further, described defoamer is BYK141 or BYK052.
Further, described wetting agent is BYK104S.
A kind of preparation technology of smoke-inhibiting type indoor ultrathin steel structure fireproof coating, it is characterised in that preparation process includes：
(1) after adding solvent to disperse through the stirring at low speed of 500r/min defoamer, wetting agent, uniform liquid is formed；
(2) fire proofing additive, titanium dioxide and suppression cigarette filler are added into the uniform liquid described in step (1) respectively, is first passed through
Sand mill is sucked after the high-speed stirred dispersion 10-15min of 1500r/min, is sanded to fineness and is less than 80 microns, obtain fire prevention slurry；
(3) after split resin binder and levelling agent being added into the fire prevention slurry described in step (2), the low speed through 500r/min is equal
Even dispersion 10-15min, gets product.
The present invention compared with prior art, has the following advantages that：
The present invention is by specific binder resin, i.e. acrylic resin, acrylic acid modified alkyd resin, amino resins with specific
Ratio when being used in mixed way, fire endurance can be effectively improved, when carrying out fire endurance with big panel method and determining, use
Composite base-material improves 8-15min or so, the compound resin with other same types than the fire resistance period using single binder resin
Base-material compares the fire protecting performance for significantly improving fireproof coating, while coating adhesion is strong, good weatherability.
The APP degree of polymerization that the present invention is used is more than 1000, and heat endurance is good, water-soluble weak, the table in expansion process
Reveal good anti-flammability and smoke-suppressing, its fire proofing additive constituted with foaming agent, carbon forming agent can react under specified proportioning
Completely so that the existing relatively good heat-insulated rate of foaming layer has certain intensity again, plays relatively good flameproof effect.
The suppression cigarette filler that the present invention is prepared can make the fireproof coating of preparation be foamed in the case where fiery or hot environment is met the circle of formation
Shape, it is tiny it is fine and close, quality is high, the carburization zone that is not easily broken, the fire endurance time is effectively raised, while same relative to other
The fireproof coating of type can effectively reduce expansion process moderate stimulation gas, moreover it is possible to can significantly increase after fireproof coating meets fire expansion
