The invention discloses a medicinal PVC (
polyvinyl chloride) hard sheet and a production process thereof. The medical PVC hard sheet comprises the following raw materials in parts by weight: 80 to 85parts of PVC, 10 to 15 parts of EVOH (
Ethylene-
Vinyl Alcohol), 5 to 7 parts of PE-g-MAH (
Polyethylene-grafted-
Maleic Anhydride), 3 to 5 parts of a
plasticizer, 2 to 4 parts of a stabilizer, 6 to 8 parts of an
antistatic agent and 0.4 to 0.8 part of a
lubricant. The production process of the medicinal PVC hard sheet comprises the following steps of step 1, blending: firstly, mixing and uniformly stirring the 80 to 85 parts of PVC, the 10 to 15 parts of EVOH and the 5 to 7 parts of PE-g-MAH, then pouring into an extruder, extruding to form a strip, and then carrying out
water cooling,
granulation and
drying, to obtain a blended particle; step 2, molding: firstly mixing and uniformly stirring the blended particle, the 3 to 5 parts of the
plasticizer, the 3 to 4 parts of the stabilizer, the 6to 8 parts of the
antistatic agent, the 0.4 to 0.8 part of the
lubricant and 4 to 6 parts of antibacterial
powder, then pouring into the extruder, extruding, then calendaring to form a sheet, controlling a thickness to be 0.15 mm to 0.6 mm, subsequently, cooling for forming, and finally, trimming and rolling. The medicinal PVC hard sheet has excellent barrier property, antistatic property and
antibacterial property, and is applicable to
medicine packaging.
