Abstract
The invention discloses a PE film production process which comprises the following steps: feeding a material, performing extrusion plasticization, cooling to mold, coating the surface, drying, drawing, performing electric spark treatment, coiling and cutting. The material used in the feeding step comprises polyethylene which is high in impact resistance, so that a product can be prevented from being contaminated, corroded or scratched in the production, transportation, storage and use process, original smooth and bright surfaces can be protected, and thus the product quality and the market competitiveness can be improved.
Description
Technical field
The present invention relates to field of thin film fabrication, particularly a kind of PE film production process.
Background technology
High density polyethylene (HDPE) is high, the nonpolar thermoplastic resin of a kind of degree of crystallinity.PE has excellent resistance to great majority life and the characteristic of chemicals for industrial use.Non-hygroscopic and the steam-preventing had of this polymer, can be used for packing purposes.PE has good electrical property, and particularly dielectric strength is high, makes it be applicable to electric wire very much.Existing PE black and white is double-colored waits Coloured film, at waterproofing membrane production with in using, because of the yellow used oil in pitch, penetrate into the surface of PE film, film being turned yellow, affects outward appearance, depositing nitrogen element aborning to being coated with the catalyst poisoning phenomenon caused in silicone oil process simultaneously.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of PE film production process, to solve the above-mentioned multinomial defect caused in prior art.
For achieving the above object, the invention provides following technical scheme: a kind of PE film production process, is characterized in that: comprise the steps:
(1) feed intake: raw material comprise polyethylene, PET, ethyl acetate and aluminium foil, wherein polyethylene 40wt%, PET 30wt%, ethyl acetate 20wt% and aluminium foil 10wt%;
(2) melting; Raw material are placed in smelting device, carry out adding thermal agitation;
(3) coating: be coated in by coating on base material, forms film;
(4) face is coated with: the film after being coated with in face is sent into baking oven and carried out hot air dries;
(5) dry: film surface coats ternary polymerized polypropylene and slipping agent, use hot air dries, hot air temperature is 60-70 DEG C, and drying time is 20-40 second;
(6) curling: the tension force of described technology is 10N;
(7) cut.
Preferably, after described step (4) hot air seasoning, naturally cool, temperature is controlled at 15 DEG C.
Preferably, in described step (5), the concentration of ternary polymerized polypropylene is 96wt%-97.5wt%, and the concentration of described slipping agent is 2.5wt%-4wt%.
The beneficial effect of above technical scheme is adopted to be: to adopt technical scheme of the present invention, the raw material of charging technology comprise polyethylene, this material is excellent in cushion effect, the product of protection is in production and processing, transport, storage and use procedure in not contaminated, corrosion, scratch, protect original bright and clean glossy surface, thus improve quality and the market competitiveness of product, make in process of production, there is a good cushioning effect, add it and melt poly-property, the transparency is higher, control the tension force in technology, effectively decrease its quality, by electric spark treatment process, there is good cohesiveness and combined strength bination, also enhance moisture resistance and heat resistance, it is made to can be applicable in printing.
Detailed description of the invention
The following detailed description of the preferred embodiment of the present invention.
A kind of PE film production process, is characterized in that: comprise the steps:
(1) feed intake: raw material comprise polyethylene, PET, ethyl acetate and aluminium foil, wherein polyethylene 40wt%, PET 30wt%, ethyl acetate 20wt% and aluminium foil 10wt%;
(2) melting; Raw material are placed in smelting device, carry out adding thermal agitation;
(3) coating: be coated in by coating on base material, forms film;
(4) face is coated with: the film after being coated with in face is sent into baking oven and carried out hot air dries, after hot air seasoning, naturally cools, temperature is controlled at 15 DEG C;
(5) dry: the concentration that film surface coats ternary polymerized polypropylene is 96wt%-97.5wt%, and the concentration of slipping agent is 2.5wt%-4wt%, and by hot air dries, hot air temperature is 60-70 DEG C, and drying time is 20-40 second;
(6) curling: the tension force of described technology is 10N;
(7) cut.
Use technical scheme of the present invention, the raw material of charging technology comprise polyethylene, this material is excellent in cushion effect, relatively good to the security performance of liquid and parrot packaging, can deposit in refrigerator, also can use in high temperature, extrude in casting technique by cooling, ventilate and the formation of cooling three step, make in process of production, there is a good cushioning effect, add it and melt poly-property, the transparency is higher, control the tension force in technology, effectively decrease its quality, by electric spark treatment process, there is good cohesiveness and combined strength bination, also enhance moisture resistance and heat resistance, it is made to can be applicable in printing, in step (4), process for cooling adopts air cooling way, make product not yielding, ensure its quality of production.
Above-described is only the preferred embodiment of the present invention, it should be pointed out that for the person of ordinary skill of the art, and without departing from the concept of the premise of the invention, can also make some distortion and improvement, these all belong to protection scope of the present invention.
