“…Nowadays the way of modification is mainly adding different types of flame-retardant agent, for example, halogenated flame-retardants, phosphorus flame-retardants, nitrogenated flame-retardants, silicone flame-retardants and so on [1][2][3][4]. Fontaine G made a study of using intumescent flame retardant (IFR) in PLA and a third component was added into the system of ammonium polyphosphate (APP)/melamine to get more synergy [5].…”

As PLA composites are easy to kindle, making flame-retardant composites is particularly important. PLA can be widely used after improvement. In the process of making cotton stalk bast fibers reinforced PLA composites, adding APP/PER a type of flame-retardants in the experiment produces a kind of composites with good flame-retardant property. Orthogonal experiment table including length and mass fraction of fibers, molding temperature and addition of flame-retardants was devised. Then the study focused on the flame-retardant property of the composites and the analysis of range and variance were done. The optimal processing condition was obtained: length of fibers was 8mm, mass fraction of fibers was 30%, molding temperature was 175°C and addition of flame-retardants was 10%. Fibers reinforced PLA composites with APP/PER got better flame-retardant property than the composites without APP/PER, with the LOI rising 6.61. This kind of composite can be extensively applied in many fields.

The effect of very small amounts of ultra strong acid salts on the flame retardancy of polycarbonate PC has been studied. The experiments were planned with emphasis on the reproducibility as the concentration of the additives were in the range of 100 ppm to 10000 ppm. The addition of ultra strong acid salts as low as 100 ppm resulted in the retardancy of the PC combustion. The self-extinguishing time was 5 seconds or shorter, which is useful for industrial application. Thermogravimetry, pyrolysis-gas chromatography-mass spectrometry, and elemental analysis showed that the thermal degradation is accelerated by adding the acid salts. The 5! and 50! weight loss temperatures decreased and the amount of the carbonaceous residue at 700c C also decreased. The results did not coincide with the general relationship between the flame retardancy of polymeric materials and thermal degradation nor with the general effect of the amount of additives.
