Abstract
The invention discloses a fireproof powder coating with expansion steel structure, pertaining to the construction material filed. The fireproof powder coating is made from epoxy resin, polyester resin, curing agent, catalyst, carbonization agent, vesicant, expansion promoter, strengthening agent, toughening agent, flow agent, degassing agent, flowable and pigment filler according to the traditional production method. The invention has the advantages of ultra-thin coating and good fireproof and heat insulation performance.
Description
Technical field
The present invention relates to a kind of buckling type steelwork fire-proof powdery paint, belong to the building coating technical field.
Background technology
Along with technical progress and social development, people more and more pay attention to environmental protection, powder coating with " economy, environmental protection, efficient, energy-conservation " is rapidly developed, and various functional powder coating are come out one after another, and the research of buckling type steelwork fire-proof powdery paint is in the ascendant.The expanding fire-proof paint that November 20, disclosed Chinese patent 02112798.0 related in 2002 can only be used for fields such as household electrical appliances, cabinet, belongs to the finishing fire retardant paint scope, good flame retardation effect, but effect of heat insulation is undesirable, can not be used for steel structure fireproofing.On August 22nd, 2007, disclosed Chinese patent 200710020217.9 had fire prevention and anticorrosion dual-use function, installed to 2mm ± 0.2mm and just can reach fire resistance period more than the 1h but must be coated with.
Summary of the invention
The object of the present invention is to provide a kind of buckling type steelwork fire-proof powdery paint, have that coating is ultra-thin, the advantage of back-fire relief heat-proof quality excellence.
Technical scheme of the present invention is that its composition proportioning is:
Component concentration (Wt)
Resins, epoxy 30～45
Vibrin 10～25
Solidifying agent 1～7
Flow agent 0.8～4
Air release agent 0.1～1
Ammonium polyphosphate 20～30
Trimeric cyanamide 15～20
Tetramethylolmethane 7～15
Help swelling agent 1～8
Strengthening agent 5～10
Color stuffing 0～10
Raising agent 0.1～0.5
Resins, epoxy is the Resins, epoxy of oxirane value 0.09～0.14mol/100g in the prescription, and vibrin is the powder coating polyester resin special of acid number 68～82mgKOH/g.They all are filmogens, guarantee that coating has good bonding strength, mechanical property.Solidifying agent is the phenols epoxy hardener, and its consumption is decided according to the consumption of Resins, epoxy and vibrin.Flow agent and air release agent are the auxiliary agents that improves powder coating surface decoration performance, and tetramethylolmethane is a char-forming agent, and trimeric cyanamide is a whipping agent, and ammonium polyphosphate is a catalyzer, select for use thermostability greater than 270 ℃ high molecular ammonium polyphosphate (n＞1000, II type).To help swelling agent be fusing point such as the amino tetrazole of 5-phenyl tetrazole, 5-, 1-chloro-5-phenyl tetrazole, 1-bromo-5-phenyl tetrazole and decomposition temperature greater than 200 ℃ tetrazole material, these materials are met fire initial stage decomposes in coating, and emit rare gas element N
2, the fire-retardant and expansion effect of heat insulation of reinforcement coating.Strengthening agent is selected staple glass fibre for use, to increase the physical strength of expansion coating.Color stuffing is used for the ornamental of coating and improves the physical and mechanical properties of coating.Flow promotor Al
2O
3-C or gas phase SiO
2Be used to improve flowability, the powder utilization of powder coating.After coating was subjected to thermal softening, the ammonium polyphosphate decomposes generated phosphoric acid, and then, further dehydration generates polyphosphoric acid or poly-metaphosphoric acid, and the tetrazole thermal endothermic decomposition is emitted rare gas element simultaneously, and coating is tentatively expanded; Polyphosphoric acid or poly-meta-acid and the reaction of polyol tetramethylolmethane form charring layer; Non-flammable gases is emitted in the thermolysis of whipping agent melamine, and the further bubbling of charring layer is expanded, and forms the fine and close uniform cellular thermofin of porous.
The present invention has following advantage and effect compared with prior art: this coating adopts the tetrazole material as helping swelling agent, and rate of expansion is higher, expanding layer is than even compact, heat insulation back-fire relief effect excellence when coat-thickness is low, can reach the above fire performance of 1h.
Embodiment
Further illustrate the solution of the present invention and effect below in conjunction with embodiment.The raw material consumption of each embodiment of buckling type steelwork fire-proof powdery paint of the present invention is by weight as table 1, the salient features such as the table 2 of its corresponding frie retardant coating.
Main raw material title and manufacturer among the embodiment are as follows:
Resins, epoxy: E-12, the South Sea, Zhejiang Province medicine group;
Vibrin: P5127, DSM coating resin company;
Ammonium polyphosphate APP (II), n＞1000: generation Anhua, Shandong worker company limited;
5-phenyl tetrazole, the amino tetrazole of 5----Changzhou are contained magnificent chemical industry company limited;
JECP-03B---Changshu is good sends out company limited chemical.
Other is the commercial goods.
The manufacture method of each embodiment is identical, and its method is as follows:
At first press vibrin, Resins, epoxy, the flow agent blending dispersion of formula ratio with ammonium polyphosphate, tetramethylolmethane, trimeric cyanamide, 5-phenyl tetrazole and formula ratio, be added in the screw extrusion press extrude, behind the compressing tablet, fragmentation, with broken thing melt extrude once more, compressing tablet, fragmentation, so repeat to melt extrude, compressing tablet, broken operation 2 times and make pre-dispersed mixture, preceding warm 85-95 ℃ of forcing machine, warm 110-120 ℃ of back, mixing of materials accumulated time 60-200s.Mix with other each component then, deliver to again that forcing machine is extruded, compressing tablet, fragmentation; At last, with ACM grinding machine abrasive dust, can obtain this ultra-thin expansion type steel structure fire-proof powder coating after sieve, packing.
