Abstract
The invention belongs to technical field of polymer materials, specially a kind of acrylic resin for manufacturing medical infusion bottle cap.The acrylic resin is composition, and which is formed through melting mixing by resin binder, acid neutralizing agent and antioxidant.Wherein resin binder is propylene and ethylene atactic copolymer, and its ethylene contents is 0.5～4wt%, and the melt temperature of resin binder is 140～165 DEG C, and melt flow rate (MFR) is 2.0～10.0g/10min；The antioxidant is 1 for weight ratio:0.3～1:The mixture that 8 Hinered phenols antioxidant is constituted with phosphite ester kind antioxidant, the mass ratio of the resin binder, acid neutralizing agent and antioxidant is 100：(0.01～0.05)：(0.02～0.25).The resin stability that the present invention is obtained is good, with good heat resistance, rigidity and toughness.
Description
Technical field
The present invention relates to technical field of polymer materials, is related to a kind of acrylic resin, more particularly to one kind is exclusively used in manufacture doctor
Acrylic resin with Infusion bottle lid.
Background technology
The manufacture raw material of plastics medical infusion bottle cap is by polyvinyl resin processing and fabricating.At present, plastics medical infusion bottle substantially by
Acrylic resin is manufactured.Due to polyethylene bottle cap and the difference of polypropylene bottle material, cause the two weldability bad, draw ring
Connection is easy to crack, the defect such as is difficult to open.
For solving the above problems, Chinese patent application 200410024446.4 is using a kind of follow-on polypropylene transfusion bottle of blending
Lid material, which is mainly made up of acrylic resin, polyvinyl resin and thermoplastic elastomer (TPE), per 100 parts of PP resins in formula
In containing PE resin 30-60 part, thermoplastic elastomer (TPE) POE and KN resin be respectively 15-40 and 5-30 part.Due to
It is that the blending of multiple plastic resins is formed, cost increases, bad stability.
Content of the invention
In order to overcome the deficiencies in the prior art, it is an object of the invention to provide a kind of for manufacturing medical infusion bottle cap poly- third
Olefine resin, manufactures medical infusion bottle cap by its acrylic resin for adopting this single.Due to adopting and producing the same of infusion bottle
A type of plastic resin, therefore more preferably, weldability is more excellent for the compatibility of bottle cap bottle portion.Production technology letter of the present invention
Single, low cost, resin stability are good, with good heat resistance, rigidity and toughness.
The following is the specific technical scheme of the present invention.
A kind of acrylic resin for manufacturing medical infusion bottle cap, the acrylic resin be composition, its by resin binder,
Acid neutralizing agent and antioxidant, form through melting mixing；Wherein resin binder is propylene and ethylene atactic copolymer, and its ethene contains
Measure as 0.5～4wt%, the melt temperature of resin binder is 140～165 DEG C, and melt flow rate (MFR) is 2.0～10.0g/10min；
The antioxidant is 1 for weight ratio:0.3～1:The mixture that 8 Hinered phenols antioxidant is constituted with phosphite ester kind antioxidant,
The mass ratio of the resin binder, acid neutralizing agent and antioxidant is 100：(0.01～0.05)：(0.02～0.25).
The melt flow rate (MFR) of above-mentioned resin binder is preferably 3.0～7.0g/10min.
In above-mentioned antioxidant, the weight ratio preferably 1: 0.8～1 of Hinered phenols antioxidant and phosphite ester kind antioxidant：6.
Preferably, above-mentioned Hinered phenols antioxidant is 1,3,5- trimethyl -2,4,6- tri- (- 4 hydroxybenzyl of 3,5- di-t-butyl) benzene
Or 1,1,3- tri- (2- methyl -4- hydroxyl -5- tert-butyl-phenyl) butane；Above-mentioned phosphite ester kind antioxidant is three (2,4- bis-
Tert-butyl-phenyl) double (2,4- di-tert-butyl-phenyl) pentaerythritol esters of phosphite ester or diphosphorous acid.
Above-mentioned acid neutralizing agent is calcium stearate or hydrogenation talcum powder.Melt flow rate method of testing is according to ASTM
D 1238 is tested, and corresponding international test standards are ISO 1133.
The beneficial effects of the present invention is：The single acrylic resin that the present invention is provided has high temperature resistant sterilising well
Can, after 115 DEG C of high-temperature water sterilization 30 minutes, bottle cap performance not only no substantially deteriorates, and has on the contrary a certain degree of
Lifting, bottle cap are not ftractureed with bottle.Resin stability of the present invention is good, with good heat resistance, rigidity and toughness.
Specific embodiment
Below will the invention will be further described by specific embodiment.
【Embodiment 1～4】
Acrylic resin, is composition, and component includes resin binder, acid neutralizing agent and antioxidant, forms through melting mixing.
Wherein resin binder is propylene and ethylene atactic copolymer, and its ethylene contents is 0.5～4wt%；The melt temperature of resin binder
For 140～165 DEG C, melt flow rate (MFR) is 3.0～7.0g/10min.Acid neutralizing agent is calcium stearate；Antioxidant is 1,1,3-
Three (2- methyl -4- hydroxyl -5- tert-butyl-phenyl) butane and the mixture of three (2,4- di-tert-butyl-phenyl) phosphite ester,
The two proportioning is 1:1.The composition of polypropylene resin composite is shown in Table 1, and performance is shown in Table 2.
Table 1.
Table 2.
As seen from Table 2, whole embodiments all have preferable rigidity and toughness, after high-temperature water sterilization, melt flows
Speed does not change substantially, and rigidity and toughness have larger lifting, illustrate that the high temperature resistant sterilization ability of whole embodiments is excellent, bottle
After lid sterilization, performance is improved further.
