Abstract
The invention relates to a modified polypropylene bottle cap material, which mainly comprises the following components in parts by weight: 100 parts of polypropylene (PP) resin, 20 to 40 parts of polyethylene (PE) resin, 15 to 35 parts of styrene-b-ethylene-co-butylenes-b-styrene block copolymer (SEBS), and 10 to 30 parts of KN resin. The bottle cap material has reasonable formula, simple process and stable performance, is suitable for batch production in purification plants, and is particularly suitable for being used as an inner cap material of an infusion bottle.
Description
Technical field
The present invention relates to a kind of macromolecular material, specifically a kind of improved polypropylene bottle cap material.It is particularly suitable for doing infusion bottle inner cap material.
Background technology
We know that the used bottle cap of existing polypropylene infusion bottle is mainly made by polyethylene (PE) resin treatment.Polyethylene bottle cap and polypropylene bottle are owing to the difference of material, and weldability is bad, and draw ring connects easy to crack, is difficult for opening.Polyethylene bottle cap complete processing is also unreasonable, the production cost height, and inconvenience is produced in enormous quantities in the cleaning shop.At present, the seal closure on the medical infusion bottle is made up of enclosing cover, isoprene-isobutylene rubber pad and inner cap mostly.Infusion bottle bottle material therefor is generally polypropylene, and infusion bottle bottle cap material therefor is mainly polyethylene and polypropylene.Polyethylene bottle cap and polypropylene bottle are owing to materials variances, and weldability is bad, and draw ring connects easy to crack, is difficult for opening.In order to address the above problem, a kind of polypropylene infusion bottle bottle cap material is disclosed among the applicant's Chinese patent Zl200410024446.4, this material is mainly used in the infusion bottle enclosing cover, but normal sliding pin phenomenon and the chip problem that comes off that occurs in its practical application.It is not suitable for makes infusion bottle inner cap material.
Summary of the invention
Technical problem to be solved by this invention is to overcome above-mentioned the deficiencies in the prior art, provides a kind of prescription reasonable, and physicals is good, stable performance, technology is simple, is suitable for doing infusion bottle inner cap material, the modified polypropylene bottle cap material that can produce in enormous quantities in the cleaning shop.
The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of modified polypropylene bottle cap material, it is characterized in that: it is made up of polypropylene (PP) resin, polyethylene (PE) resin, styrene-ethylene/butylene-styrene block polymer (SEBS) and KN resin, and its components by weight percent is: 100 parts of PP resins, PE resin 15-25 part, SEBS elastomerics 25-40 part, KN resin 10-30 part.
The present invention is with PP resin and the PE resin main body plastics as bottle cap material, and this is that the toughness deficiency adds an amount of PE resin and can improve its toughness because the fragility of PP resin material own is big.Polyethylene of the present invention (PE) is one or both the mixture in new LDPE (film grade) (LDPE), the linear low density polyethylene (LLDPE).
The present invention selects for use styrene-ethylene/butylene-styrene block polymer (SEBS) and KN resin to the PP resin modified, reduces the hardness and the tensile strength of PP resin, improves its processing fluidity.
Modified polypropylene bottle cap material of the present invention is suitable for doing infusion bottle inner cap material, and its advantage is: when transfusion needle inserts infusion bottle, sliding pin phenomenon and the chip problem that comes off does not appear in inner cap, greatly reduces because of chip comes off and enters the danger of human body with soup.The present invention fills a prescription rationally, and technology is simple, and stable performance can be produced in enormous quantities in the cleaning shop.
Embodiment
The invention will be further described below in conjunction with embodiment: a kind of modified polypropylene bottle cap material of the present invention, it mainly is made up of polypropylene (PP) resin, polyethylene (PE) resin, styrene-ethylene/butylene-styrene block polymer (SEBS) and KN resin, and its components by weight percent is: 100 parts of PP resins, PE resin 15-25 part, SEBS elastomerics 25-40 part, KN resin 10-30 part.
The present invention is with PP resin and the PE resin main body plastics as bottle cap material, and this is that the toughness deficiency adds an amount of PE resin and can improve its toughness because the fragility of PP resin material own is big.Polyethylene of the present invention (PE) is one or both the mixture in new LDPE (film grade) (LDPE), the linear low density polyethylene (LLDPE).
The present invention selects for use styrene-ethylene/butylene-styrene block polymer (SEBS) and KN resin to the PP resin modified, reduces the hardness and the tensile strength of PP resin, improves its processing fluidity.
Institute's PP resin that uses is the M1600 product as the trade mark of Shanghai Petrochemical Co. Ltd.'s production in the present invention prescription; The PE resin is that the trade mark that Yanshan Mountain company limited of China Petrochemical Industry produces is the 1C7A product; Styrene-ethylene/butylene-styrene block polymer SEBS is 1657 products for the trade mark that the company of rising of U.S. section produces; The KN resin is the KS240 product for the trade mark that Mitsui company produces.
The present invention mixes various raw materials by prescription, granulation in twin screw extruder then, and injection moulding in the cleaning shop then obtains goods.Resulting product meets national standard YBB00242004 " polypropylene combination cover for plastic infusion container standard (draw-ring type) " part 2: inner cap.
The prescription of each concrete embodiment is formed and the modifying material physicals sees Table one:
