Abstract

The invention discloses a medical material suitable for infusion bags and a preparation method thereof. The material is composed of the following components in parts by mass: 58-76 parts of polyethylene, 13-28 parts of antioxidant, 4-11 parts of initiator 5-17 parts of calcium stearate, 20-42 parts of acetone, 11-25 parts of epoxy soybean oil, 14-21 parts of dibutyl sebacate, 12-19 parts of dioctyl phthalate and 24-36 parts of ethylene-butene copolymer. The medical material has higher elongation at break, notch impact strength and tensile strength, and is used for producing infusion bags.

Description

technical field [0001] The invention belongs to the field of medical materials, and in particular relates to a medical material suitable for an infusion bag and a preparation method thereof. Background technique [0002] Disposable plastic infusion bags are made of special medical-grade plastics. At present, polyvinyl chloride and polypropylene are the most widely used materials. Compared with traditional glass bottle packaging, they have many advantages: (1) Improve the quality of infusion, Reduce infusion reactions; (2) The production process is simple and efficient, reducing several complicated processes such as bottle washing, capping film, capping rubber stoppers and pre-treatment, saving manpower, material and financial resources, shortening the production cycle and improving efficiency ; (3) Less investment, simple filling machinery, low price, more importantly, the small footprint of the machinery, which can reduce the area between 100 levels, and greatly reduce hous...
