Narration as table 2 is intelligible, as seen from Table 2, and extinguishment characteristics, fluorescent lifetime and drip and to drop down performance and all be improved widely.Just, halogen-containing as in Comparative Examples 6, pointing out
The simple increase of fireproofing agent and ANTIMONY TRIOXIDE SB 203 99.8 PCT amount provides good extinguishment characteristics, but the fusion dropping of test sample still can be observed, and drips and to drop down performance and a bit do not improve.Can find out that from table 2 example 3 has added linking agent and free-radical initiator that Comparative Examples 4 does not add especially, the result does not demonstrate extinguishment characteristics, and the fusion dropping also has been observed.And, its extinguishment characteristics and drip and to drop down performance and all not have improvement.Corresponding with Comparative Examples 4, only increased the addition of halogen-containing fireproofing agent and ANTIMONY TRIOXIDE SB 203 99.8 PCT, shown in Comparative Examples 7, improved extinguishment characteristics, but the fusion of still having observed test sample drips and drop down thing, and the performance of dripping is not improved.Further, in system the compound of the boron in the example 3 is especially removed, shown in Comparative Examples 5, the extinguishment characteristics and the performance of dripping have all demonstrated gratifying result, but fluorescent lifetime is much older.Fluorescent lifetime should be 30 seconds or shorter for the first time, and fluorescent lifetime should be 60 seconds or shorter for the second time, therefore, with regard to these results, can't say that this system is gratifying, however the extinguishment characteristics that has demonstrated, fluorescent lifetime drips and to drop down performance and all be improved.Further, example 4 is directly used ethene especially, and two-tetrabromo phthalimide is as halogen-containing fireproofing agent, extinguishment characteristics and drip and drop down performance and all be improved.
Now, reference table 3, when the ethylene-propylene block polymer of example 5 operating weight percentage ratios, 12% ethene (M.F.R.2.5g/10min) is as polyolefin resin especially, with example 3 is similar especially, demonstrated the good optical property of putting out, fluorescent lifetime drops down performance with dripping, Comparative Examples 8 has only been removed the radical light lead agent in the example 5 especially, the result finds out extinguishment characteristics and the performance of dripping all worsens, because not existing of due free-radical initiator just do not show the effect of linking agent.The simple increase of halogen-containing fireproofing agent and ANTIMONY TRIOXIDE SB 203 99.8 PCT amount makes extinguishment characteristics better, and as Comparative Examples 7, this point is seen, simultaneously, has observed the fusion dropping of test sample.
Further, example 6～7 is consistent with the mineral filler of example 5 interpolations especially especially.As a result, self-extinguishing can and be dripped and dropped down performance is good, but fluorescent lifetime is poor for example 5 especially to a certain extent.Example 8 usefulness tetramethylolmethanes three acrylate are as linking agent especially, and example 9 usefulness sodium tetraborates are made the boron compound especially.They have shown extinguishment characteristics preferably, drip and drop down performance and fluorescent lifetime, as being shown in the example 5 especially.
