2%, add extruder extrusion to obtain material strip after high-speed mixer mix homogeneously, the processing temperature of extruder by feed opening to
The temperature of ground is followed successively by：180 DEG C, 185 DEG C, 190 DEG C, 195 DEG C, 200 DEG C, 205 DEG C, 210 DEG C, 215 DEG C, extruder main frame turns
Speed is 80-120r/min；
The pelletizing after water-cooled by above-mentioned material strip, obtains modified pellet.
In the present invention, recycled PET raw material used can be various waste and old carafe, through sorting, crush, clean, being dried
The recycled PET bottles piece of the pure color obtaining afterwards.In order to prepare Color tunable, stable performance recycled PET/ABS, it is right to need
Bottle piece color is compared strict control, and this can crush after being classified with multipair different colours carafe to can reach and want
Ask.
The present invention, compared with conventional patent of invention, has some advantage following：
1. because high-performance recovered PET/ABS that the present invention provides is thermodynamically incompatible system, in order to improve system
In biphase between the compatibility, Chinese scholars have done numerous studies and have proved, can substantially be carried by adding anhydrides graft
Active force between height is biphase, thus improve the biphase compatibility.But anhydrides material can promote the chain rupture of ester bond, lead to whole
Body mechanical performance declines.
The present invention passes through to add appropriate molecular weight regulator, during melt-processed, not only achieves between each phase
Effectively plastify, be simultaneously achieved original position chain extending reaction, the system machine that PET leads to because of molecule chain break not only can be prevented
Tool hydraulic performance decline, but also the strand having ruptured in recycled PET can be reconnected, thus being greatly improved
The combination property of alloy.
2. traditional PET/ABS alloy separately through add anhydrides graft to improve biphase between the compatibility, though
So have certain effect, main pass through wherein one and with ABS there is good physical compatibility, another be mutually mainly anhydride bond and
In PET, ester bond occurs chemical action to improve biphase intermolecular forces.But add in quick melting between anhydride bond and ester bond
During work, only small part can react raising biphase compatible.
The present invention with the addition of rare-earth salts, and this kind of rare-earth salts can effectively facilitate and occur chemistry anti-between anhydride bond and ester bond
Should, so that anhydrides graft is quickly distributed at two-phase interface, effectively play the effect of compatilizer.
3. the PET/ABS alloy before is higher to biphase raw material requirement, especially recycled PET performance is had tighter
Lattice require (molecular weight can not be too low, and degraded can not be too serious), simultaneously because PET and ABS processing temperature differs greatly, because
This, the process window producing this alloy is narrow.
Recycled PET/ABS that the present invention provides, is not strict with to recycled PET material property, and whether one
PET raw material after secondary property reclaims or repeatedly reclaims may be incorporated for being directly produced, because the addition of chain extender can in system
To effectively improve the molecular weight of recycled PET, it is to avoid the impact to system performance for the recycled PET degraded；The recovery of selection simultaneously
PET processing temperature is lower compared with virgin material PET, so not only reduces power consumption of polymer processing, also reduces the thermal oxide of ABS simultaneously, thus
Widen process window.
The present invention is cooperated by function additive, improves recycled PET body using the excellent physical and mechanical property of ABS system
The mechanical performance of system, make that the recycled PET/ABS of the present invention has high-compatibility, height draws Zhong Qiangdu, high fluidity, excellent plus
The advantages of work, it is particularly suitable for the production of complex partses and large-sized sheet material, process is simple, suitable medium-sized and small enterprises are produced in batches,
Economic benefit and social benefit are notable.
