Abstract
The present invention relates to a polypropylene transfusion bottle cover material, which is mainly composed of polypropylene (PP) resin, polyethylene (PE) resin and thermoplastic elastomer, wherein the thermoplastic elastomer comprises polyolefin elastomer (POE) and KN resin. In a compounding recipe, every 100 portions of PP resin comprises 30 to 60 portions of PE resin, 15 to 40 portions of POE, and 5 to 30 portions of KN resin. The PP resin of the present invention, which is used as main plastic, can guarantee good weldability between a bottle cap and a polypropylene bottle body; the polyolefin elastomer (POE) can lower the hardness and the tensile strength of the PP resin; the KN resin raises the fluidity of processing. The present invention has the advantages of reasonable compounding recipes, simple manufacturing process and stable performance, and can be produced in large batch in purification plants.
Description
Technical field
The present invention relates to a kind of macromolecular material, specifically a kind of improved polypropylene infusion bottle bottle 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.
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, stable performance, and technology is simple, and cost is low, the polypropylene infusion bottle 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 polypropylene infusion bottle bottle cap material, it mainly is made up of polypropylene (PP) resin, polyethylene (PE) resin and thermoplastic elastomer, thermoplastic elastomer comprises polyolefin elastomer (POE) and KN resin, contain PE resin 30-60 part, POE 15-40 part, KN resin 5-30 part in the prescription in per 100 parts of PP resins.
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.In addition, the PP resin is made the main body plastics and can be guaranteed good weldability between bottle cap and the polypropylene bottle.
The present invention selects for use thermoplastic elastomer to the PP resin modified, and polyolefin elastomer (POE) can reduce the hardness and the tensile strength of PP resin; The KN resin improves its processing fluidity.
The advantage of bottle cap material of the present invention is that the excellent weldability of bottle cap and bottle does not ftracture behind the draw ring process high-temperature sterilization, easily opens.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 polypropylene infusion bottle of the present invention bottle cap material, it mainly is made up of polypropylene (PP) resin, polyethylene (PE) resin and thermoplastic elastomer, thermoplastic elastomer comprises polyolefin elastomer (POE) and KN resin, contain PE resin 30-60 part, POE 15-40 part, KN resin 5-30 part in the prescription in per 100 parts of PP resins.
The prescription of each specific embodiment is formed and the bounce impact elasticity of material is listed table 1 in:
Table 1
| Embodiment 1 | Embodiment 2 | Embodiment 3 | Embodiment 4 | |
| PP (W531A) PE (NH755) POE (A4050) KN resin shore hardness H AMelt flow rate (MFR) g/10min tensile strength MPa elongation at break % | 100 33 26 9 93 12 10 405 | 100 54 26 15 90 14 22 786 | 100 50 30 9 94 12 12 563 | 100 55 40 20 92 16 11 398 |
Used PP resin is that the trade mark that Mitsui Sumitomo polyolefins company is produced is the product of W531A in the present invention's prescription; POE is the product of A 4050 for the trade mark that Mitsui Co., Ltd. produces; The KN resin is that the trade mark that Japanese Port リ ユ チ レ ソ Co., Ltd. produces is the product of XM104; The PE resin is that the trade mark that Japanese Port リ オ レ ア イ ソ Co., Ltd. produces is the product of NH755.
As can be seen from Table 1, all embodiment obtains comparatively ideal shore hardness, tensile strength and elongation at break.The fragility of PP resin material of the present invention own is big, and the toughness deficiency adds an amount of PE resin and can improve its toughness.In addition, the PP resin is made the main body plastics and can be guaranteed good weldability between bottle cap and the polypropylene bottle.Polyolefin elastomer (POE) can reduce the hardness and the tensile strength of PP resin; The KN resin improves its processing fluidity.
The embodiment of the invention 2 is compared with embodiment 1, and the tensile strength and the elongation at break of gained plastics are higher, and it is because increased the consumption of PE that PP toughness improves this.Embodiment 4 compares the POE consumption to be increased with embodiment 3, and hardness reduces.The consumption of KN resin increases, and the plastic melt that obtains is mobile to be improved, and visible KN resin can improve the processing fluidity of PP.
The present invention's various raw materials of filling a prescription mix, and granulation in the double-screw extruding pelletizing machine then so just can directly be carried out injection moulding on the injection moulding machine in 100,000 grades of cleaning shops, obtains goods.The resulting product color and luster is even, and outward appearance is good.Good with polypropylene infusion bottle bottle weldability, 170-180 ℃ of its welding temperature, time 2-3 second, 115 ℃ of temperature, 30 minutes time steam sterilizing and bottle do not ftracture, and bottle cap is easily opened with the 30-50 Newton force, and is easy to use.
The advantage of bottle cap material of the present invention is that the excellent weldability of bottle cap and bottle does not ftracture behind the draw ring process high-temperature sterilization, easily opens. The present invention fills a prescription rationally, and technique is simple, and stable performance can be produced in enormous quantities in the cleaning shop.
