The invention provides a preparation method of a medical non-
woven fabric composite. The method specifically includes the following steps of firstly, weighing 30-50 parts by weight of
adipic acid /
polybutylene terephthalate, 20-30 parts by weight of
polybutylene terephthalate and 30-40 parts by weight of
polycarbonate to be sufficiently mixed to obtain a mixture A; secondly, blending the mixture in the first step with 1-4 parts by weight of
antistatic agent and 0.5-2 parts by weight of
antibacterial agent, and conducting extruding and granulating through a twin-screw extruder to obtain a blend; thirdly, conducting
vacuum drying on the blend in the second step, conducting heating, fusing, extruding, stretching, cooling and self-adhering on the dried blend through a screw extruder to form a non-
woven fabric; fourthly, spraying an anti-
radiation layer on one side of the non-
woven fabric obtained in the third step, and putting the fabric into a
drying box to be dried and shaped. The prepared medical non-
woven fabric composite has antibacterial performance,
radiation prevention performance and antistatic performance and is mainly applied to preparing a medical
mask.
