The mechanical properties of PP spun-bonded non-woven, thermal properties and flame retardant performance ℃

 Method of spun-bonded non-woven production technologies and products for the first time since the late 1950 s by the dupont company, since the development in the process of art, product performance, production efficiency, etc, are the obvious advantages, in recent 20 years obtained the rapid development of the world start purpose.In 2006, a total of 255 Chinese spun-bonded production line, PP spun-bonded non-woven production by about 393 kl, but the vast majority of all these PP spun-bonded nonwoven cloth as the normal product, added value is small.Now although there are older reports of flame retardant PP and flame retardant PP fiber {1-3}, but about flame retardant non-woven and PP spun-bonded non-woven rarely reported.Now if we compared with the French in PP flame retardant masterbatch of direct spinning into a net and finishing method of flame retardant PP spun-bonded non-woven on the mechanical properties, thermal properties and flame retardant performance testing.
A experimental
1.1 raw materials and samples
PP spun-bonded non-woven [1] and flame retardant masterbatch flame retardant PP spun-bonded non-woven {2} that is provided by jiangsu yangzhou chi shing non-woven plant, including II is if in PP flame retardant masterbatch spinning directly into network legal system.Flame retardant A and B: both for environmental protection of the expansion type flame retardant containing phosphorus and nitrogen, self.Silane coupling agent: JS - D758, Shanghai jin shan chemical co., LTD. Offers.
Finishing fire retardant PP spun-bonded non-woven {3} homemade.Its preparation process is as follows: {1} use flame retardant A and two kinds of flame retardant, flame retardant B respectively made into mass fraction is 15%, 18%, 20%, 25%, 28% of the solution, and in the fluid of the flame retardant if A certain amount of silane coupling agent;{2} to 50 g/m2, 130 mmx58mm PP spun-bonded non-woven soak 10 min;{3} put the soaked in PP spun-bonded non-woven fabrics in between the two rubber roller of roller machine, squeeze out excess liquid.{4} will flame retardant finishing PP spun-bonded non-woven fabric after drying alternate {IIIA, IIIB}.
1.2 equipment
Homemade small roller coating machine, YG065 type electronic fabric tester: shandong laizhou city electronic instrument limited company, Nntzsch Sta 409 PG/pC type thermogravimetric analyzer: Germany Nntzch company production.Pechino - scanning thermal instrument Elmer said: American Perkin Elmer corporations;Critical Ooygen Index oxygen Index test instrument: the British SDL corporations.
