Abstract

The invention discloses a preparation method of a modified acrylic resin infusion bag. Firstly, organic silicone modified acrylic resin is prepared; an ethylene-propylene copolymer, a hydrogenated styrene butadiene copolymer, magnesium aluminum hydroxide carbonate, dibutyl sebacate, trimethyl phosphite and tributyl citrate are added and stirred at the speed of 600-700 r / min at the temperature of 80-100 DEG C; a solvent, magnesium stearate and cinnamon oil are added and stirred at the speed of 1,600-1,700 r / min for 50-60 min at the temperature of 120-150 DEG C, and a mixture is obtained; the mixture is extruded and granulated through a double-screw extruder and then is subjected to cooling, drying, cutting and film blowing, and the infusion bag can be processed. With the addition of tributyl citrate, the tensile strength can be effectively improved, and the infusion bag prepared through low-temperature drying can keep better elongation at break, is not prone to deformation at the high temperature and has stable performance.

Description

technical field [0001] The invention discloses a preparation method of a modified acrylic resin transfusion bag, which belongs to the field of medical supplies. Background technique [0002] Traditionally used infusion packaging materials are mainly glass bottles, but with the development of chemical technology, new chemical products suitable for infusions are emerging, and infusion packaging materials are gradually transitioning from glass bottles to PVC and non-PVC packaging soft bags. Among them, non-PVC packaging soft bags have become a focus of attention and research in the pharmaceutical and chemical industries. [0003] The invention with the application number CN201080048762.9 discloses a plastic film with oxygen absorption function and used for medical containers, and an infusion bag made of the plastic film. The plastic film is composed of at least the following four layers: the first layer (1) A polyamide obtained by ring-opening polymerization of a lactam with...
