Embodiment
Further specify technical scheme of the present invention below in conjunction with accompanying drawing and by embodiment:
The embodiment of the invention provides a kind of fire-retardant high-strength glass-fiber reinforced plastic grille, comprising: unsaturated polyester, expansible black lead and aluminium hydroxide mass ratio are 100:10-30(such as 10,20,30 etc.): 5-15(is such as 5,10,15 etc.); Solidifying agent, the mass ratio of described solidifying agent and described unsaturated polyester are 1-2(such as 1,1.5,2 etc.): 100; Promotor, the mass ratio of described promotor and described unsaturated polyester are 2:100.Wherein, solidifying agent is that methylethyl ketone peroxide and cyclohexanone peroxide mixed solution ratio are 4:1; Promotor is cobalt class promotor.
The fire retardant mechanism of expansible black lead (EG) belongs to the coagulation phase fire retardant mechanism, and is fire-retardant by delaying or interrupt by solid matter generation inflammable substance.EG is heated to a certain degree, will begin to expand, and the graphite after the expansion becomes the very low vermiform of density by original flakey, thereby forms good thermal insulation layer.Graphite flake after the expansion is the charcoal source in the intumescent system, is again thermal insulation layer, can be effectively heat insulation, delay and stop the decomposition of polymkeric substance; Simultaneously, in a large number heat absorption has reduced system temperature in the expansion process; And in the expansion process, the acid ion in the release jacket coating promotes dehydration carbonization.
And expansible black lead does not contain halogen element, does not generate poisonous and corrosive gases when being heated, and the flue gas of generation seldom; Addition is little; Without drippage; Environmental compatibility is strong, non-migratory phenomenon; UV stable and good light stability; The source is sufficient, and manufacturing process is simple.The expansible black lead stable physical property can not change below 1000 ℃.Do not affect the processing quality of material, improved the materials processing performance.
Inflatable charcoal layer must have certain rigidity competence exertion fire retardation, and the charcoal layer is thicker, and structural strength is higher, and is tightr between the charcoal layer, and then the shielding effect of charcoal layer and flame retardant effect are just better.But the common EG expansion thermal insulation layer that mainly expansion forms by own vol delays or suppresses the burning of polymkeric substance, and is not occured between the flame-retardant polymer or rare chemical action, is typical condensed phase fire retardant mechanism; And the expanded graphite bonding strength to each other that forms after expanding of EG a little less than, after the polymeric matrix burning, expanded graphite can't form firm foamed char, under the effect of flame pressure or heat convection current, the expanded graphite layer on surface may be destroyed, and forms " flying dust ", cause the forfeiture of adiabatic expansion layer, and then cause unburned polymkeric substance and lighted, flame continues to propagate, and flame retarding efficiency is limited.In addition, the EG flame-retardant polymer often shows strong " candle wick effect ", and this has also weakened its fire retardancy to a certain extent.
Together the glass-fiber reinforced plastic grille goods are carried out cooperative flame retardant by the test final decision with aluminium hydroxide and expansible black lead.Evidence cooperative flame retardant system can form comparatively fine and close expansible black lead charcoal layer, and charcoal layer hole is few, and hole wall is thicker and even, and the carbon residue amount of flame-retardant system has obvious lifting.
The embodiment of the invention provides the above; only be the better embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or change according to technical scheme of the present invention and inventive concept thereof, all should be encompassed within protection scope of the present invention.
