This invention is polypropylene resin used for making medical injector. The resin is propene and ethane atactic multipolymer, the ethane content is 0.5-5wt%. The resin contains transparent nucleating agent, acid neutralizer and antioxidant. The weigh ratios are: propene ethane atactic multipolymer/transparent nucleating agent=100/(0.08-0.40);propene ethane atactic multipolymer/ acid neutralizer=100/(0.01-0.10); propene ethane atactic multipolymer/antioxidant=100/(0.02-0.30). The transparent nucleating agent is sorbitol or organic phosphate compound, 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 has good heat endurance, intension and tenacity.
Description
Technical field
The present invention relates to a kind of acrylic resin, particularly be exclusively used in the acrylic resin of making medical syringe.
Background technology
In the prior art, the plastics injector for medical purpose generally adopts acrylic resin to make, and according to this special purposes of injector for medical purpose, its transparency of the material that is used to make and toughness all have higher requirement.Generally increase the transparency of material at present by adding nucleator, thickness is that the sheet material turbidity of 1.3mm can reach 15%, but usually nucleator adds the toughness that affiliation influences material, therefore, the existing notched Izod impact strength that is used to make the medical syringe acrylic resin is about 20J/M, and the syringe of making more easily breaks.
Summary of the invention
The invention provides a kind of acrylic resin that is used to make medical syringe, the technical problem that it will solve is to make resin have good transparency, has better toughness simultaneously.
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 syringe, this acrylic resin are propylene and ethylene atactic copolymer, ethylene content 0.5～5wt%, 140～165 ℃ of melt temperatures, melt flow rate (MFR) 6.0～30.0g/10min.Contain transparent nucleater, acid neutralizing agent and oxidation inhibitor in the resin, the content of transparent nucleater, acid neutralizing agent and oxidation inhibitor is counted with weight ratio:
Propylene and ethylene atactic copolymer/transparent nucleater=100/ (0.08～0.40);
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).
Transparent nucleater is glucitols compound or organophosphate compounds, and acid neutralizing agent is stearic
A kind of in acid calcium or the hydrogenation talcum powder or both mixtures, oxidation inhibitor are 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 esters or two (2, the 4-di-tert-butyl-phenyl) pentaerythritol esters of diphosphorous acid; The glucitols compound is preferably three (3,4-dimethyl diphenylmethylene) sorbyl alcohol or two (to the methyldiphenyl methylene radical) sorbyl alcohol.。
Compared with prior art, key of the present invention has been to select suitable acid neutralizing agent, oxidation inhibitor and transparent nucleater, and they have the higher anti-performance of separating out, and the high temperature process stable performance of resin.In addition, resin adopts propylene and ethylene random copolymerization, adds the transparent nucleater unique properties of interpolation, and this makes resin can possess the good transparency and toughness simultaneously.
Below will the invention will be further described by specific embodiment.
