Abstract
This invention is polypropylene resin used for making medical transfusion container. The resin is propene and ethane atactic multipolymer, the ethane content is 0.5-4wt%, the melting temperature is 140-165deg.C, the flowing speed is 1.0-4.1g/10min. the resin contains acid neutralizer and antioxidant, propene ethane atactic multipolymer/acid neutralizer=100/(0.01-0.10)(weight ratio); propene ethane atactic multipolymer/antioxidant=100/(0.02-0.30)(weight ratio). The acid neutralizer is one of calcium stearate or hydro-saponite or the mixture of the two, the antioxidant is one of or mixture of hindered phenol and phosphate ester. The polypropylene resin provided by this invention not only has good heat endurance, intension and tenacity, but also has better transparency.
Description
Technical field
The present invention relates to a kind of acrylic resin, particularly be exclusively used in the acrylic resin of making the medical transfusion container.
Background technology
Early stage plastics medical infusion container adopts vinylchlorid to make, but because of plasticizer for polyvinyl chloride, vinyl chloride monomer etc. is easily separated out, substantially, replaced by materials such as polypropylene, polyethylene in recent years, as Chinese patent 99814444,98807300,01813402,01111112 etc. introduce, for thermotolerance, intensity, toughness and the transparency etc. that improve material, these medical infusion containers adopt the matrix material of 3～7 layers of different resins to make usually, therefore manufacturing process is very complicated, and production cost is very high.Adopt single resin material to make the obvious technology of medical infusion container and want much simple, just introduced a kind of medical infusion container that adopts injection stretch blow moulding to make as U.S. Pat 5286540, it adopts single resin material to make, and resin is homopolymerization or and C
2～C
18The polypropylene of alpha-olefin copolymer, alpha-olefin content is 15wt%, melt flow rate (MFR) is 0.2～50g/10mi.Though this single resin material thermotolerance, intensity and toughness have all reached level preferably, but its transparency is relatively poor, therefore must add the multipolymer of propylene and 3-methyl butene-1 and increase transparency as polypropylene nucleater, the thickness that makes through injection stretch blow moulding is that the bottle turbidity of 9mm has reached 9%.
Summary of the invention
The invention provides a kind of acrylic resin that is used to make the medical transfusion container, adopt this single acrylic resin can make the medical transfusion container, the technical problem that it will solve is that requirement medical transfusion container has good heat endurance, intensity, toughness, and better transparency is arranged.
Below be the technical scheme that the present invention solves the problems of the technologies described above:
A kind of acrylic resin that is used to make the medical transfusion container, this acrylic resin are propylene and ethylene atactic copolymer, ethylene content 0.5～4wt%, 140～165 ℃ of melt temperatures, melt flow rate (MFR) 1.0～4.0g/10min.Contain acid neutralizing agent and oxidation inhibitor in the acrylic resin, the content of acid neutralizing agent and oxidation inhibitor is counted with weight ratio:
Propylene and ethylene atactic copolymer/acid neutralizing agent=100/ (0.01～0.10);
Propylene and ethylene atactic copolymer/oxidation inhibitor=100/ (0.02～0.30).
Acid neutralizing agent is a kind of in calcium stearate or the hydrogenation talcum powder or both mixtures, and oxidation inhibitor is a kind of in Hinered phenols antioxidant or the phosphite ester kind antioxidant or both mixtures.
When oxidation inhibitor was the mixture of Hinered phenols antioxidant and phosphite ester kind antioxidant, the weight ratio of Hinered phenols antioxidant and phosphite ester kind antioxidant was preferably 1/ (0.2～8).
Above-mentioned Hinered phenols antioxidant preferably takes from 1,3,5-trimethylammonium-2,4,6-three (3,5-di-t-butyl-4 hydroxybenzyl) a kind of in benzene, two-[3,3-two-(3-tert-butyl-hydroxy phenyl)-butyric acid] glycol ester or four [β-(3, the 5-di-tert-butyl-hydroxy phenyl) propionic acid] pentaerythritol ester; Phosphite ester kind antioxidant is preferably taken from three (2, the 4-di-tert-butyl-phenyl) phosphorous acid ester or 2,4,6-tri-tert phenyl-(2-butyl-2-ethyl-1, ammediol) phosphorous acid ester.
What add acid neutralizing agent and oxidation inhibitor in the acrylic resin usually is essential, but the acid neutralizing agent and the oxidation inhibitor that make an addition to the acrylic resin that is used to make the medical transfusion container have higher requirement again, it must have the higher anti-performance of separating out, and does not influence the transparency of resin simultaneously again.Key of the present invention has been to select suitable acid neutralizing agent and oxidation inhibitor, and they not only have the higher anti-performance of separating out, make an addition in the resin simultaneously after, minimum to the influence of transparency.Therefore, compared with prior art, the acrylic resin that is used to make the medical transfusion container provided by the invention not only has good heat endurance, intensity and toughness, and has better transparency.
Below will the invention will be further described by specific embodiment.
