Abstract
The utility model relates to a flame-retardant polymer foam material. The utility model is characterized in that the flame-retardant polymer foam material comprises a polymer foam plastic layer, wherein an organic flame retardant layer is arranged on the surface of the polymer foam plastic layer. The flame-retardant polymer foam material has simple and reasonable structure; since good compatibility exists between the selected organic flame retardant layer and the polymer foam plastic layer made of organic material, the organic flame retardant layer can be closely stuck together with the polymer foam plastic layer; the unit concentration of the organic flame retardant layer gathered on the surface is higher than that of the flame retardant dispersed inside the foam; and when the foam product is in contact with flame, the flame is isolated from the foam product through the flame retardant covered on the surface, and simultaneously, the flame retardant is further enriched on the contact surface between the foam product and the flame along with heat shrinkage of foam, and the self-extinguishing property is better, so that, the utilization ratio of the flame retardant can be greatly improved.
Description
Technical field
The utility model relates to a kind of foamed material, particularly a kind of flame-retarded polymer foams.
Background technology
Polymer foam is the aggregation that gas dispersion forms in solid polymer.Foamed plastics has light weight, heat insulation, buffering, insulation, advantage such as anticorrosion, cheap, therefore is used widely in building, packing, industry, agricultural, transportation, war industry, aerospace industry, and application enlarges day by day.Market increases fast the demand of foamed plastics in recent years.Wherein principal item has polyurethane (PU) soft and rigid foam, polystyrene (PS) foamed plastics, polypropylene (PP) foamed plastics and polyethylene (PE) foamed plastics four big classes.
Polymer foam especially occurs with forms such as foam piece, films with various forms, is their combustibility based on molding or great shortcoming of polymer foam goods of extruding.With extrusion foaming polystyrene foam plastics (XPS) is example, as a kind of excellent insulating material, extrusion foaming polystyrene foam warming plate (XPS) is obtained in the building heat preservation field more and more widely and is used, the particularly extensive application on skyscraper, but the annual fire damage that causes because of it is flammable is very huge, fire-retardant contradiction also becomes increasingly conspicuous, national legislation is also more and more stricter to the fire-retardant requirement of these materials, and the anti-flammability demand of improving the polymeric foam article in these application is increased.
Comparatively general fire-retardant way is to add various fire retardants in the polymer foam manufacture process, wherein general with the application of the organic compound of halo and organophosphorus ester, (HBCD) is widely used in the poly styrene polymer foam as HBCD, and halophosphoric acid ester type compound and phosphoric acid ester fire retardant are widely used one big class addition type organic fire-retardants in the polyurethane foam plastics.
In the WO91/19758 patent, describe the limited anti-flammability of HBCD and disclose a kind of method of improving anti-flammability well known in the prior art, it uses aliphatic bromide, particularly the mixture of HBCD and aromatic bromide bromine diphenyl ether for example the time is as the fire retardant that is used for the PS foams.Another piece US6,579,911 disclose application HBCD and phosphate or phosphorus compound and flow improver additive improves anti-flammability efficient well known in the prior art.In patent 99814260.3, disclose and come the fire retardant polystyrene foam of polymers with expanded graphite and phosphorus compound.
A more serious problem of adding HBCD HBCD existence in extrusion foaming polystyrene foam plastics XPS is that fire retardant decomposes easily, can severe corrosion equipment and cause the decay of fire resistance, at US5,639,799 and US5, mention these problems in 717,001 and disclose the method for improving the heat endurance of the HBCD that is used for the styrenic foam compositions.
The another one problem that the interpolation fire retardant must be noted that in polymer foam is, must strict control join the flame-retardant additive in the polymer foam composition and the amount of synergist, because under the high-load of flame-retardant additive, the architecture quality and the surface quality of their meeting negative effect foams, intensity or its insulating properties of reduction foam.In non-foaming polymer composition, the general loading of flame-retardant additive is in the foam compositions.Therefore, the fire retardant that is used for polymer foam composition must be efficiently a spot of, still can not fine solution fire retardant few additive in the prior art and high flame retardant require between contradiction.
