Abstract

The invention belongs to the technical field of biodegradable materials, and particularly relates to a method for preparing an infusion bag by adopting a biodegradable infusion bag special material. The biodegradable infusion bag special material is composed of an inner-layer special material, a middle-layer special material and an outer-layer special material, and the inner-layer special material is prepared from PBAT, PLA, a hydrolysis-resistant agent, talcum powder and nano-zinc oxide; the special material of the middle layer is prepared from PPC-TPU, PPCP and MDI; and the outer layer special material is prepared from PBAT, a hydrolysis-resistant agent, a light stabilizer and a lubricant. The preparation method comprises the following steps: 1) preparing the inner layer special material; the preparation method comprises the following steps: 1) preparing an inner-layer special material, 2) preparing an intermediate-layer special material, 3) preparing an outer-layer special material, and 4) producing the infusion bag: carrying out blow molding on the inner-layer special material, the intermediate-layer special material and the outer-layer special material by using a three-layer co-extrusion extruder to form a film, and then welding the film into the infusion bag by using a welding machine.The infusion bag prepared by the method is good in barrier property and can be completely biodegraded, and the preparation method is simple and easy to implement.

Description

technical field [0001] The invention belongs to the technical field of biodegradable materials, and in particular relates to a method for preparing an infusion bag by using a special material for a biodegradable infusion bag. Background technique [0002] Infusion refers to the infusion of large doses of injection liquid into the body by intravenous drip. The infusion liquid is usually packaged in glass or plastic infusion bottles or infusion bags. Because the glass infusion bottle is easy to fall off and the glass particles block the capillaries, and the cost is high, fragile, and heavy, etc., there are many inconveniences in the use process, and now it has been gradually replaced by the infusion bag. [0003] PVC infusion bag, good transparency, soft texture, long storage time; not easy to be corroded by acid and alkali; low leakage, good heat tolerance. And has good tensile, flexural, compressive and impact resistance, flexibility, cold resistance, brittleness, hardness,...
