Description
(1) technical field
The present invention relates to a kind of frie retardant coating and production technique thereof.
(2) background technology
Fire is the normal higher a kind of disaster of occurrence frequency in the property the sent out disaster, and in the fire failure of countries in the world, it is the first that building fire occupy, and along with the development of economy and urban construction, the loss that single fire caused is increasing.Based on being extensive use of in long span building of steel framed structure in recent years; the fire safety of steel building has caused that people pay close attention to greatly, brushes that ultra-thin (expanding fire-proof paint of coat-thickness≤3.0mm) is the main method of large-span steel Building Fire Protection protection.The effect of flameproof protection: when meeting high temperature; fire protection coating is taken away heat rapidly when the steel component surface forms lightweight heat insulation foam charcoal layer; slowing down temperature conducts to steel member matrix; prolong the temperature rise time of member; make it to satisfy 1～3 hour fire endurance of state architectural design fire safety rules and force standard-required, be beneficial to evacuating personnel, fire-fighting fire extinguishing.
Steel structure fire-proof paint mainly is made of materials such as binder resin, char forming catalyst, char-forming agent, whipping agents.In recent years, the frie retardant coating of China's exploitation continues to bring out.For example, (2002,35 (6): 27～29) adopt aminoresin and acrylic resin mixture is the frie retardant coating of base-material to Qu Jinqing etc., and when the build of coating was 1mm, its fire endurance was 60min for Qu Jinqing etc., material protection; Chen Guodong etc. (Chen Guodong etc., New Building Materials, 2001, (11): 19～21) formulation for coating material is improved, when the coating build was 1mm, its fire endurance reached more than the 60min; (Lv Jiuzhuo etc., modern coating and application, 2001, (4): 10～12 such as Lv Jiuzhuo; 2001, (5): 5～7; Beijing Institute of Petrochemical Technology's journal, 2002,10 (2): 4～9) Yan Zhi coating, coat-thickness 2.09mm, fire resistance period 66min; (2001,31 (2): 16～18) report is developed into super-thin steel structure fire-proof paint to Wang Huajin etc. for Wang Huajin etc., coatings industry, and when paint thickness≤3mm, its fire endurance is 95min; The SCB ultra-thin expansion fireproof coating of Ministry of Public Security Sichuan fire-fighting scientific research institution development, coat-thickness 2.67mm, fire endurance reaches 147min; The GWB outdoor steel structure frie retardant coating that White Cloud Mountain, Guangzhou thunder waffle factory develops; (Liu Guoqin, Zou Min, Panshihua University's journal, 2002,19 (6): 5～7) such as BSC-A steel structure fire-proof paint that Nanjing, Yangzhou speciality coating factory releases.
Above-mentioned patent, the steel structure fire-proof paint of bibliographical information all is with toluene, organic solvents such as industrial naptha are dispersion medium: acrylic resin, chlorinated rubber, aminoresin, Synolac etc. are bonding material: with starch, dextrin, N.F,USP MANNITOL, sorbyl alcohol, the polyol that carbon contents such as tetramethylolmethane are high is a char-forming agent: with urea, trimeric cyanamide, carbotriamine, Dyhard RU 100, volatile salt, clorafin, hexamethylenetetramines etc. are whipping agent: with phosphoric acid dihydro amine, Secondary ammonium phosphate, the phosphoric acid poly cyanamid, ammonium polyphosphates etc. are catalyzer: add titanium dioxide, zinc sulfide white, talcum powder, Calucium Silicate powder, silica, inorganic color stuffings such as kaolin constitute.Because inorganic filler surface wetting ability, make the dispersiveness and the poor stability of frie retardant coating, deposit process generation layering, sedimentation, and the synergy between component of therefore having scattered and disappeared, cause the expansion multiplying power of frie retardant coating low, expansion charcoal layer compactness is poor, and fire insulation performance is reduced.
(3) summary of the invention
