Acquired results are as follows：
1 PET/PE alloy materials mechanical property table of the present invention of table
Wherein comparative example 1 is commercially available PC sheet materials (manufacturer is that plastic cement Co., Ltd of Shanghai gentry)；
For commercially available regeneration ABS (acrylonitrile-butadiene-styrene copolymer) sheet material, (manufacturer is Dongguan City intelligence to comparative example 2
Exert oneself plastic material Co., Ltd)；
Comparative example 3 is commercially available regeneration PP (polypropylene) sheet material (manufacturer be Yiwu City assemble a crowd plasthetics Co., Ltd)；
Comparative example 4 is the PET/PE alloy sheet materials being prepared using the method for the embodiment of the present invention 5, and difference lies in do not make
With chain extender and antioxidant；
Comparative example 5 is the PET/PE alloy sheet materials being prepared using the method for the embodiment of the present invention 5, and difference lies in only make
With chain extender, without using antioxidant.
From table 1 it follows that PET/PE alloys sheet material of the present invention has higher tensile strength and elongation at break, it is bright
It is aobvious higher than regeneration ABS and PP sheet materials, also above existing PET/PE alloy materials, but slightly below PC.Conjunction prepared by completely new PET and PE
Alloy of the mechanical property of gold plaque material better than regenerative PET and PE, this absolutely proved in PE secondary processing process hydraulic performance decline or
It is not high containing impurity or purity.PET/PE alloys sheet material of the present invention has been able to the level for reaching conventional macromolecular sheet material,
Through disclosure satisfy that practical application request.In addition, by comparison as can be seen that using only chain extender, compared to completely without using chain extension
Agent and antioxidant can significantly improve the mechanical property of gained PET/PE alloy materials, and use chain extender and antioxidant can also be into
One step obtains cooperative synergism effect.
In addition, as it can be seen from table 1 the elongation at break of PET/PE alloy materials of the present invention is with the increase of sheet thickness
And reduce, the especially elongation at break of the sheet material of 0.4mm can reach 581%, this absolutely proves phase of the present invention to PET and PE
Capacitive has larger improvement.
Fig. 1 is the SEM photograph of 5 gained 2.3mm thickness PET/PE alloy materials of the embodiment of the present invention.As seen in Figure 1,
The present invention expects that PET and the complete weave ins of PE form continuous phase using recycled PET and recycling PE, and blending effect is very good.
Under normal conditions, it needs to carry out pre-dried to it before PET melting extrusions, removes moisture removal, reduce PET water solution.
The present invention processes PET/PE alloy materials before melting extrusion without drying process, and the performance of material has also reached the expection of experiment.
The preparation method of PET/PE alloy materials of the present invention, saves intermediate link, it is higher to can not only obtain performance
Product, and intermediate processing link is also eliminated, mass energy is saved, this is the key that PET high-valued.
The present invention can effectively solve the problem that the high-valued application of recycled PET, especially PET/PE alloy materials, have higher property
Valency ratio.
Oxidation induction time (OIT) is to measure sample under high temperature (200 degrees Celsius) Oxygen Condition to take place and urge automatically
The time of oxidation is the index for evaluating material heat-resisting degradation capability in processing and forming, storage, welding and use.Oxygen
Change induction period (abbreviation OIT) method be it is a kind of use differential thermal analysis (DTA) using plastic molecules chain be broken when exothermic reaction as
Foundation, the method for testing plastics accelerated ageing degree in high-temperature oxygen.Its principle is：By plastic sample and inertia reference substance
(such as aluminium oxide) is placed in differential thermal analyzer, it is made to use the indoor inert gas of oxygen fast exchange sample at a certain temperature
(such as nitrogen).DTA curve (differential thermal spectrum) caused by test is aoxidized due to sample
Variation, and oxidation induction period (time) OIT (min) is obtained, to evaluate the anti-heat aging performance of plastics.
The oxidation induction time of gained PET/PE alloy materials of the invention is as shown in table 2：
2 present invention gained PET/PE alloy material oxidation induction times of table
