Abstract
Polypropylene resin used for manufacturing medical transfusion bottles is composition, and the components comprise resin binders, acid neutralizers and antioxidants; wherein, the resin binder are random copolymer of propylene and ethylene, the ethylene content of the resin binders is 0.5 percent to 4 wt percent, the melting temperature is 140 DEG C to 165 DEG C, and the melt flow rate is 1.0g to 4.0g/10min. The mixture radio of the components by the weight ratio is as follows: the ratio of the resin binder and the acid neutralizer is equal to 100 : 0.1 to 0.06; the ratio of the resin binder and the antioxidant is equal to 100 : 0.02 to 0.30. The antioxidants are one or the mixture of hindered phenolic antioxidants and phosphate antioxidants; the acid neutralizers are the mixture of calcium stearate and hydrogenated talcum powders, the ratio of the calcium stearate and the hydrogenated talcum powders by the weight ratio is equal to 1: 0.8 to 1.3. The invention has the advantage that the adding amount of the acid neutralizer is reduced on the premise that the same acid neutralization effect is obtained.
Description
Technical field
The present invention relates to a kind of acrylic resin, particularly be exclusively used in the acrylic resin of making medical infusion bottle.
Background technology
Early stage plastics medical infusion container adopts vinylchlorid to make, but because of vinyl chloride monomer, softening agent 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.At present, the most normal use is propylene and ethylene atactic copolymer, and with regard to performances such as thermotolerance, intensity, toughness and transparency, propylene is compared with other material with ethylene atactic copolymer has remarkable advantages.
The catalyzer that is used to prepare propylene and ethylene atactic copolymer generally all contains the Cl ion, and the Cl ion can can't be present in the copolymer product with avoiding.The Cl ionic exists can form sour environment, and this will impel polymer degradation, thereby influence the quality of its goods infusion bottle.Usually adopting the method for adding acid neutralizing agent in propylene and ethylene atactic copolymer to prevent the generation of degrading in the prior art, is that 200410017402.9 Chinese patent application is introduced as application number.But for propylene and ethylene atactic copolymer, acid neutralizing agent also belongs to a kind of impurity in essence, and the physicals of copolymer artcle will be subjected to the increase of its add-on more or less and descend.Therefore, if can obtain same sour neutralization, the add-on that reduces acid neutralizing agent has positive effect beyond doubt.
Summary of the invention
The invention provides a kind of acrylic resin that is used to make medical infusion bottle, the technical problem that it will solve is that requirement obtains to reduce the add-on of acid neutralizing agent under the prerequisite of same sour neutralization.
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 medical infusion bottle, this acrylic resin is a composition, component comprises resin binder, acid neutralizing agent and oxidation inhibitor, wherein resin binder is propylene and ethylene atactic copolymer, its ethylene content is 0.5～4wt%, melt temperature is 140～165 ℃, and melt flow rate (MFR) is 1.0～4.0g/10min.
In weight ratio, the ratio of each component is:
Resin binder: acid neutralizing agent=100: 0.01～0.06;
Resin binder: oxidation inhibitor=100: 0.02～0.30.
Above-mentioned oxidation inhibitor is a kind of in Hinered phenols antioxidant or the phosphite ester kind antioxidant or both mixtures; Acid neutralizing agent is calcium stearate and the talcous mixture of hydrogenation, in weight ratio, and calcium stearate: hydrogenation talcum powder=1: 0.8～1.3.
Above-mentioned oxidation inhibitor is preferably the mixture of Hinered phenols antioxidant and phosphite ester kind antioxidant, and the weight ratio of Hinered phenols antioxidant and phosphite ester kind antioxidant is 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 esters or two (2, the 4-di-tert-butyl-phenyl) pentaerythritol esters of diphosphorous acid.
Key of the present invention is that the contriver found through experiments to the selection of acid neutralizing agent and the combination of prescription thereof, with this acid neutralizing agent that is used in combination, can reduce the add-on of acid neutralizing agent under the prerequisite that obtains same sour neutralization.Therefore, the present invention compared with prior art has tangible advantage.
Below will the invention will be further described by specific embodiment.
