Abstract
The invention discloses a method for manufacturing an anti-dropping COC (cycloolefin copolymer) plastic bottle, which comprises the following steps of: weighing and uniformly mixing COC (cycloolefin copolymer) resin which is used as a main material and 5 percent of elastic body and a certain proportion of adhesive which are used as auxiliary materials according to a certain ratio; then putting the mixture into plastic bottle manufacturing equipment to carry out injection moulding; sequentially carrying out primary manual operation self-checking, secondary QC (quality control) spot check and third QA (Quality Assurance) spot check; and putting qualified products checked by the three processes into a storage. The elastic body is a polyethylene octylene copolymer elastic body. After the polyethylene octylene copolymer elastic body is mixed with the COC which is used as the main material, the anti-dropping capacity of the product can be improved. By the adhesive, the COC raw material and the polyethylene octylene copolymer elastic body can be well molten together, so that the stratification phenomenon is not generated. The anti-dropping property of the COC bottle is improved to 0.7 meter from 0.3 meter. The requirements of a client on the appearance and the chemical property can be well met.
Description
Technical field
The present invention relates to plastic bottle and make raw material field, the preparation method of particularly a kind of anti-drop COC (cycloolefin copolymer resins) plastic bottle.
Background technology
The making composition of raw materials of existing plastic bottle, generally comprising COC cycloolefin copolymer resins is major ingredient, COC is the copolymer of cyclic polyolefin and vinyl monomer, and it has high transparent, high water vapor barrier and characteristics such as gas barrier property, low water absorbable, resistance to chemical reagents and low stripping; But the plastic bottle that COC makes exists and to fall frangible disadvantage, fills water and will break into pieces at 0.2-0.3m, has the bump will be damaged in transportation, through unresolved always this problem of process debugging repeatedly.
Summary of the invention
In order to overcome the defective that above-mentioned prior art exists, the invention provides a kind of preparation method of anti-drop COC plastic bottle, the anti-dropping ability of the plastic bottle of making obviously improves, and can satisfy outward appearance and chemical property well.
To achieve these goals, technical scheme of the present invention is as follows:
A kind of preparation method of anti-drop COC plastic bottle mainly may further comprise the steps:
(1) be major ingredient with cycloolefin copolymer resins COC, 5% elastomer and a certain proportion of binder are that auxiliary material is weighed in proportion and evenly mixed;
(2) above-mentioned even mixed raw material is put into production equipment injection mo(u)lding, operative employee's self check for the first time, underproof pulverizing is sold; The qualified next process that enters;
(3) plastic bottle that aforesaid operations worker self check is qualified carries out the QC sampling observation second time, underproof doing over again, the qualified product polybag of packing into;
(4) the qualified product of QC sampling observation for the second time carries out QA sampling observation for the third time, and underproof product is done over again, the qualified product carton warehouse-in of packing into.
Above-mentioned COC raw material is the copolymer of cyclic polyolefin and vinyl monomer, and it has high transparent, high water vapor barrier and characteristics such as gas barrier property, low water absorbable, resistance to chemical reagents and low stripping;
Above-mentioned elastomer is a polyethylene octene copolymer elastomer, and the flexible chain coiled structure of octene and the ethylene chain of crystallization make toughness of its existing excellence and good processability as the physical crosslinking point, and its density is at 0.852-0.880g/cm
3
Described elastomer can improve the anti-dropping ability of product with after the COC raw material mixes, and method is to add 5% polyethylene octene copolymer elastomer, stir 20 minutes through drum-type spice machine after, produce in the used device.
But two kinds of raw material fusions well, for COC raw material and polyethylene octene copolymer elastomer are fused together well, do not produce lamination, added a certain proportion of " binder ", made the COC plastic bottle of producing in its production process can be good at satisfying client's outward appearance and chemical property requirement.
The invention has the beneficial effects as follows, improve, make the COC bottle bring up to 0.7 meter for 0.3 meter, obtain client's approval and favorable comment from original resilience through a series of prescription,
Description of drawings
Fig. 1 is a schematic flow sheet of the present invention.
The specific embodiment:
Be easy to understand understanding in order to make creation characteristic of the present invention, technological means and to reach purpose, further set forth the present invention below in conjunction with specific embodiment.
Embodiment:
Referring to Fig. 1, a kind of preparation method of anti-drop COC plastic bottle has changed the composition of raw materials and the technological process of the traditional COC plastic bottle of former making, improves through prescription, the anti-dropping ability of producing of COC plastic bottle obviously improves, and brings up to 0.7 meter from 0.3 meter of original resilience.
The key step of the preparation method of above-mentioned anti-drop COC plastic bottle is as follows:
(1) be major ingredient with cycloolefin copolymer resins COC, 5% elastomer and a certain proportion of binder are that auxiliary material is weighed in proportion and evenly mixed;
(2) above-mentioned even mixed raw material is put into production equipment injection mo(u)lding, operative employee's self check for the first time, underproof pulverizing is sold; The qualified next process that enters;
(3) plastic bottle that aforesaid operations worker self check is qualified carries out the QC sampling observation second time, underproof doing over again, the qualified product polybag of packing into;
(4) the qualified product of QC sampling observation for the second time carries out QA sampling observation for the third time, and underproof product is done over again, the qualified product carton warehouse-in of packing into.
COC raw material described in the above-mentioned steps (1) is the copolymer of cyclic polyolefin and vinyl monomer, and it has high transparent, high water vapor barrier and characteristics such as gas barrier property, low water absorbable, resistance to chemical reagents and low stripping;
Described elastomer is a polyethylene octene copolymer elastomer, and the flexible chain coiled structure of octene and the ethylene chain of crystallization make toughness of its existing excellence and good processability as the physical crosslinking point, and its density is at 0.852-0.880g/cm
3
Because COC raw material and the fusion well of polyethylene octene copolymer elastomer, for COC raw material and polyethylene octene copolymer elastomer are fused together well, do not produce lamination, added a certain proportion of " binder ", made the COC plastic bottle of producing in its production process can be good at satisfying client's outward appearance and chemical property requirement.
Described elastomer can improve the anti-dropping ability of product with after the COC raw material mixes, and method is to add 5% polyethylene octene copolymer elastomer, stir 20 minutes through drum-type spice machine after, produce in the used device.
More than show and described basic principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
