Abstract:The structure and mechanical performance of PA6 and the PA6 mixed with PPgMAH and wollastonite induced by panmilling were studied by particle size analysis, TEM observation, viscosity average molecular weight measurement and mechanical properties testes. The results showed that the pan type milling equipment has very high efficiency in pulverizing engineering plastic PA6; wollastonite contributes to the crushing of PA6 particles and the decreasing of its molecular weight when they are ground together. The particle size of PA6 decreased to about 80 nm when PA6 was comilled with wollastonite and PPgMAH for 28 cycles of pan milling. The high mechanical performance PA6/PP/wollastonite composite was prepared using the micropowder, which was obtained by comilling PA6 with wollastonite and PPgMAH.
Keywords:nylon 6  polypropylene  pulverizing  composite
