Description
Technical field
The invention belongs to the frie retardant coating technical field, relate to the indoor scumbling formed steel construction of a kind of anti-hydro carbons frie retardant coating, particularly a kind of to have sticking power good, the indoor scumbling formed steel construction of the anti-hydro carbons frie retardant coating that fire-proof and thermal-insulation is effective.
Background technology
The framework of modernization heavy construction and petrochemical industry facility adopts steel construction more; yet; the thermal conductivity of steel is large; be generally 52W/ (mK); once run into fire; fire scene temperature reaches 700 ℃ mostly in 10min, and the yield strength of invar material sharply drops to 40% left and right of normal-temperature and loses bearing capacity this moment, therefore must carry out flameproof protection to steel construction.Adopt expanding fire-proof paint to apply protection to steel construction, one of most economical beyond doubt, easy, effective means.Expanding fire-proof paint is sprayed to steel surface, foaming and intumescing when coating is subject to fire, form a difficulty than tens times of former thick coatings and fire spongy carbonaceous layer, its thermal conductivity is low, be generally less than 0.2W/ (mK), steel are played to the fire-proof and thermal-insulation effect, prevent or delay steel strength decreased avoids causing building collapse owing to heating up rapidly in fire.
At present, the steel structure fire-proof paint of China is mostly solvent-borne type, although its good combination property exists and waste resource, contaminate environment, infringement health of human body, has the shortcomings such as potential safety hazard, range of application is subject to certain limitation.And Water-borne inflation type refractory coating is compared with the solvent-borne type frie retardant coating, aspect fire-proof and thermal-insulation effect, sticking power, ornamental and water tolerance, still there is a big difference, in a lot of fields, can not replace the solvent-borne type frie retardant coating.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, designed the indoor scumbling formed steel construction of a kind of anti-hydro carbons frie retardant coating, solved that scumbling formed steel construction frie retardant coating is ubiquitous in the situation that fire easily comes off, tack is poor, the problem of fire-proof and thermal-insulation weak effect.
The present invention realizes that the technical scheme that goal of the invention adopts is, the indoor scumbling formed steel construction of anti-hydro carbons frie retardant coating, key is: A component TBA type epoxy resin frie retardant coating and B component kymene 00 solidifying agent, and press ratio of quality and the number of copies (1-3): 1 is formulated; Wherein the formula of A component TBA type epoxy resin frie retardant coating by the mass fraction proportioning is: tetrabromo bisphenol-a epoxy resin 15-22 part, first solidifying agent 10-15 part, ammonium polyphosphate 20-24 part, trimeric cyanamide 5-10 part, tetramethylolmethane 5-10 part, antimonous oxide 1-5 part, chlorinated paraffin 1-5 part, aluminium hydroxide 20-25 part, zinc borate 15-20 part.

A component TBA type epoxy resin frie retardant coating and B component kymene 00 solidifying agent, press ratio of quality and the number of copies 2: 1 formulated; Wherein the formula of A component TBA type epoxy resin frie retardant coating by the mass fraction proportioning is: 15 parts of tetrabromo bisphenol-a epoxy resins, 10 parts, the first solidifying agent, 20 parts of ammonium polyphosphates, 5 parts of trimeric cyanamides, 5 parts of tetramethylolmethanes, 1 part of antimonous oxide, 1 part of chlorinated paraffin, 20 parts, aluminium hydroxide, 15 parts of zinc borates.
Described the first solidifying agent is Toluene-2,4-diisocyanate, 4-bis-[N, N-dimethylamino the third urea].
The present invention be take tetrabromo-bisphenol (TBA) epoxy resin as filmogen and ammonium polyphosphate, trimeric cyanamide, tetramethylolmethane, antimonous oxide, chlorinated paraffin, aluminium hydroxide, the composite TBA of the obtaining type of zinc borate epoxy resin frie retardant coating A component, kymene 00 solidifying agent is the B component, by m (A): m (B)=1: 1 composite forming.This frie retardant coating foaming effect is good after testing, the carbide growing amount large, the amount of being fuming is few, coating adhesion is strong, resistance to acids and bases is good.
Preparation method of the present invention is, with tetrabromo-bisphenol (TBA) with epoxy chloropropane (EHC) under the effect of sodium hydroxide solution, obtain low-molecular-weight TBA type epoxy resin by polymerization progressively, realized the high molecular of fire-retardant bromo element; Take tetrabromo bisphenol-a epoxy resin and solidifying agent as filmogen and ammonium polyphosphate, trimeric cyanamide, tetramethylolmethane, antimonous oxide, clorafin, aluminium hydroxide, the composite A of the obtaining component of zinc borate, take solidifying agent kymene 00 as the B component, and A component and B component are pressed (1-3): the composite indoor thin section steel structure fire-resisting paint of anti-hydro carbons that obtains of 1 ratio of quality and the number of copies.
The fire retardation of brominated epoxy resin is to carry out free radical chain reactions in gas phase, its mechanism is mainly that the brominated epoxy resin decomposes produces HBr, catch aflame living radical and generate active lower bromine free radical, make burning slow down or end, react as follows:

When coating carries out the thermogravimetric test before uncured, it in 20-150 ℃, is mainly the volatilization of small solvent molecule; 150-260 ℃ of mistake quality is less, and it is stable that coating basically keeps after solvent evaporates is complete; 260～750 ℃ are lost the quality maximum, tetrabromo bisphenol-a epoxy resin is decomposing more than 300 ℃, suitable with the decomposition temperature of matrix resin and fire retardant etc., at this one-phase, coating melting, base-material mainly occurring decomposes small molecules such as emitting HBr, brominated epoxy resin starts to decompose, ammonium polyphosphate (APP) decomposes emits NH and phosphoric acid, and metaphosphoric acid and tetra-sodium are emitted in the further pyrolysis dehydration of phosphoric acid, and these acid make the oh group dehydration carbonization of tetramethylolmethane (PE) as dewatering agent; Meanwhile, trimeric cyanamide (MEL) decomposes generation NH3, and bubbling is by the coating jack-up of melting, and formation porous foam carbonaceous layer, covers substrate surface, has reduced the effect of external heat source to base material, thereby has made base material be subject to better protecting.750 ℃ are no longer lost quality later, and charring layer no longer decomposes.
Trimeric cyanamide was separated and is discharged NH3 220～400 ℃ of time-divisions, and what after this carry out is the dehydration carburizing reagent, continues to proceed to 548 ℃ of left and right, and rate of weight loss is later substantially constant.Trimeric cyanamide accounts for 90% the thermolysis of 220～500 ℃.From the initial decomposition temperature of ammonium polyphosphate and trimeric cyanamide, observe, the decomposition temperature of whipping agent is a little more than the decomposition temperature of char forming catalyst, and collocation rationally.
The decomposition of tetramethylolmethane mainly concentrates between 180-500 ℃, and it resolves between the thermolysis active zone of charcoal temperature range and APP, MEL and is complementary, and guarantees that thus combustion-supporting adjuvant system has reasonably collaborative warm area.
The present invention be take TBA epoxy resin as filmogen and ammonium polyphosphate, trimeric cyanamide, tetramethylolmethane, antimonous oxide, chlorinated paraffin, aluminium hydroxide, the composite TBA of the obtaining type of zinc borate epoxy resin frie retardant coating A component, kymene 00# solidifying agent is the B component, by m (A): m (B)=(1-3): the 1 composite two-pack TB type epoxy resin frie retardant coating that obtains ambient cure.
The invention has the beneficial effects as follows, this frie retardant coating has that foaming effect is good, the carbide growing amount is large, the amount of being fuming is few, coating adhesion is strong, resistance to acids and bases is good, fire-proof and thermal-insulation is effective.
