Study On Quantum Energy Particle Doped Polypropylene Functional Masterbatch And Meltblown Nonwoven Fabric

Using silane coupling agent KH550 to treat the surface of quantum energy(EQ)particles,and Thermogravimetric(TG),Fourier transform infrared spectroscopy(FTIR),contact angle method,affinity degree method and activation index method were used to determine the treatment effect indirectly.The results showed that KH550 silane coupling agent and EQ particles had a good grafting reaction,and the surface of EQ particles changed from non-polar to polar.The PP was blend with EQ particle with the twin—screw extruder to get EQ particle/PP functional master-batch that quality ratio was 3/97,7/93.Differential scanning calorimeter method(DSC)?Thermogravimetric(TG)?X-ray diffraction(XRD)and scanning electron microscope(SEM)was used to research the thermal properties,crystallization properties and the dispersion of EQ particles in the matrix of PP chips and PP functional master batch.The results show that the EQ particles doped PP master-batch crystallinity increased,EQ particles dispersed well in PP matrix,through the test and performance analysis to determine the thermal rheological properties,spinning temperature maximum temperature at 235 ?.Using pure PP chips and EQ particle/PP functional master batchas raw materials,two kinds of melt blown nonwovens were fabricated by using a small melt blown test line.SEM was used to research fiber diameter and the internal structure of nonwovens,the pore size distribution,porosity,permeability,mechanical properties and far-infrared emissivity,antibacterial properties were tested.The results show that EQ particles make the melt-blown non-woven fabric loose,increased the number of large pores,increased permeability,reduced fracture strength,increased elongation at break,far-infrared emission capacity greatly improved,and to give its antibacterial properties.
