Abstract
The invention discloses a PET protective film production process which comprises the process steps of screening raw materials, namely selecting 35 percent of PET plastic, 25 percent of polypropylene, 30 percent of ethyl acetoacetate resin and 10 percent of glycol ester formate, and performing melting, modification, extrusion casting, cooling, corona treatment, scrap edge removal and reeling to prepare a PET protective film. The process is reasonable, simple, high in efficiency and speed, reasonable in raw material selection and lower in cost, the process flow is greatly shortened, the PET protective film can be rapidly degraded, and environmental pollution is reduced.
Description
Technical field
The present invention relates to PET protection film field, particularly a kind of PET protection film production technique.
Background technology
PET protection film is the common daily necessitiess of present people, it is good that PET protection film has the transparency, it is moist good to hinder, excellent heat resistance, easy to use, the advantages such as low price are widely used in all trades and professions, but PET protection film is in the market mainly based on polypropylene PET protection film, severe contamination is brought to environment, also be called as " white pollution " with its refractory organics, and itself can discharge obnoxious flavour, threat is brought to the healthy of people, application number is the production technique that CN02128406.7 discloses a kind of PET protection film, it take Biodegradable resin as main raw material, by processing aid, biological degradation auxiliary agent, dispersing auxiliary, photosensitizer additive mixes according to a certain percentage, be processed into PET protection film under certain conditions, this PET protection film can microbiological deterioration, under the condition having light, degradation speed is faster, eliminate the environmental pollution that PET protection film is brought, but its working condition is indefinite, can equipment and technology reach requirement and fail to understand, can produce get a desired effect cannot ensure.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of PET protection film production technique, 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 PET protection film production technique, is characterized in that, its processing step is as follows:
(1) raw material screening: choose 35%PET plastics, 25% polypropylene, 30% methyl aceto acetate resin and 10% formic acid glycol ester;
(2) melt: add in smelting device by raw material after screening in step (1), heat 30 minutes, temperature controls at 120-150 DEG C;
(3) modification: aluminium foil is added in the fused solution in step (2), and mix under the condition of vacuum stirring;
(4) curtain coating is extruded: by the mixed melting liquid in step (3) through T-shaped membrana oralis casting machine melt extrusion PET protection film;
(5) cool: the melt PET protection film extruded in step (4) is close on cooling roller and cools;
(6) corona treatment: by cooling the PET protection film obtained in step (5), carry out corona treatment through corona treatment;
(7) excise slitter edge to batch: the PET protection film both sides slitter edge obtained in step (6) is excised and batches packaging.
Preferably, in described step (2), described temperature controls at 130 DEG C.
Preferably, in described step (3), the content of described aluminium foil is 2% ~ 5% of fused solution.
The beneficial effect of above technical scheme is adopted to be: the present invention is by the raw material screening to polylactic acid plastic particle, melt, modification, extrude curtain coating, cooling, corona treatment and excision slitter edge batch the production technique that seven large steps complete PET protection film, make its rational technology, succinctly, shortened process greatly, efficiency is high, speed is fast, material choice is reasonable, cost is lower, capable of being fast degraded, reduce environmental pollution, most importantly on the basis of original PET protection film performance, its thermotolerance is enhanced, wear resistance and toughness, in raw material screening, make polylactic acid plastic granular size moderate, the particle that enlarge active surface is conducive to next step melts, and the selection of poly-lactic acid material, biological degradation very can be obtained, reduce environmental pollution, vacuum stirring condition in modification, ensure that fused solution is even, fine and close, bubble-free, material modified adding makes the heat-resisting of PET protection film, wear-resisting and toughness strengthens, especially adding of cobalt powder its degradation speed under the condition having light is accelerated, the installation examining thick device at extrudate flow Yanzhong β ray ensure that PET protection film produces the uniform automatization of thickness, in cooling, the control of cooling temperature ensure that the planeness on PET protection film surface, safety, convenient, reliably, there are very wide market outlook.
Embodiment
The following detailed description of the preferred embodiment of the present invention.
Show the specific embodiment of the present invention: a kind of PET protection film production technique, is characterized in that, its processing step is as follows:
