Embodiment 1
[0021] A kind of preparation method of non-woven composite material, is characterized in that, comprises the steps:
[0022] (1) Take 70 parts of polypropylene a with a melt index of 50g / 10min, 2 parts of softening agent of half the amount and 1 part of color masterbatch of half the amount according to the weight ratio, and stir with the stirring machine to form the mixed raw material A; The melt index is 30g / 10min, 15 parts of polypropylene b, 2 parts of softener in the other half and 1 part of color masterbatch in the other half are stirred by a stirring machine to form a mixed raw material B;
[0023] (2) Feed component A of the mixed raw material into a screw extruder and melt at 260°C; feed component B of the mixed raw material into another screw extruder and melt at 230°C; The melts extruded by the two screw extruders are transported to the melt filter through the melt pipeline for filtration, and the melt pressure is 5MPa, and then sent to the metering pump, and then en...
