Description
Technical field
The present invention relates to technical field of polymer materials, and in particular to a kind of on-deformable PET/ montmorillonite-based nanos of resistance to compression
Composite sheet and preparation method thereof.
Background technology
PET (PET) is a kind of saturated linear thermoplastic engineering plastic, and its rim charge can be returned with waste product
Receive, its contained chemical element is equally carbon, hydrogen, oxygen with paper, belongs to degradability plastics.PET bottle light weight, intensity are high, colourless
Bright, surface gloss is high, in glass-like appearance, plasticity and mechanical property are good and nontoxic, tasteless.In recent years, common PET bottle
The packaging of carbonated beverage, mineral water and pure water has been widely used in it, as global topmost beverage packaging form.So
And, there are some restraining factors in application aspect in PET：Melt strength is poor, crystalline rate relatively slow, poor dimensional stability, it is impossible to full
The need for the industrial fast injection of foot is molded.Though adding nucleator contributes to the raising of PET crystalline rates, nucleator price is held high
It is expensive, as one " bottleneck " restricting its large-scale application.
Montmorillonite (MMT) have can bloating tendency and interlayer cation interchangeability, its modified is added as nucleator
It is added in raw material and reduces cost and can also improve the combination property of PET bottle.Therefore document《PET/MMT nano composite materials
Prepare and its application in flexible package punch》Its two characteristics are dexterously utilized, with the MMT through organic-treating to PET
Fusion intercalation copolymerization is carried out, PET/ MMT nano composite materials are obtained, the crystalline rate of the composite is fast, to gas, liquid
Good barrier property, intensity, modulus, heat distortion temperature be high and transparent, nontoxic, tasteless, non-breakable, is fully applicable to tea-drinking
The packaging of the liquid such as material, oil product and carbonated beverage.
But also there is bad mechanical property, resistance to compression when being used for flexible package punch in the PET/ MMT nano composite materials in text
The defect such as performance is weak, it is impaired so as to cause packed article to be easily deformed in transportation, bring one to producer and consumer
Fixed economic loss so as to it is existing imvite modified and add effective auxiliary agent with improve PET composite material machinery and
Compressive property.
The content of the invention
It is an object of the invention to provide a kind of on-deformable PET/ montmorillonite-based nanos composite sheet of resistance to compression and its making
Method, to overcome the deficiencies in the prior art.
The object of the present invention is achieved like this：
A kind of on-deformable PET/ montmorillonite-based nanos composite sheet of resistance to compression, it is characterised in that by the raw material system of following weight portion
Into：PET resin 55-60, ethylene ethyl acrylate 20-21, sodium-based montmorillonite 6-8, wheat stalk 15-18, glass fibre 10-
11st, nano-calcium carbonate 0.7-0.9, nano titanium oxide 1.1-1.4, Sodium Benzoate 7-9, p-aminobenzoic acid 8-10, N330 charcoal
Black 0.3-0.5, Firebrake ZB 0.1-0.2, paraffin 5-7, suitable quantity of water.
A kind of preparation method of the on-deformable PET/ montmorillonite-based nanos composite sheet of described resistance to compression, it is characterised in that bag
Include following steps：
（1）Sodium-based montmorillonite is added water and is made suspension, 80-90 DEG C is warming up under agitation, add Sodium Benzoate, p-aminophenyl
Formic acid, was gradually heating to 100 DEG C in 30 minutes, added nano titanium oxide keeping temperature to continue to stir 1-2 hours, naturally cold
But to room temperature, filtering, washing to neutrality, vacuum drying, grinding to form superfine powder must be modified sodium-based montmorillonite；
（2）By heating paraffin to molten condition, add nano-calcium carbonate keeping temperature ultrasonically treated 20-25 minutes, immediately by institute
Mixed liquor is uniformly sprayed at fiberglass surfacing, dry modified glass-fiber；
（3）By wheat stalk dries pulverizing, in input high-speed mixer, PET resin, ethylene ethyl acrylate high-speed stirred are added
10-20 minutes, add step（1）、（2）Material and other residual components high-speed stirreds 30-40 minutes, squeeze after drying through single screw rod
Go out machine and extrude to obtain plastic master batch；
（4）By step（3）Pellet is crystallized, dry after extrusion plasticizing, then sheet material is made through die head, most afterwards through cooling down glazing, leading
Draw, cut discharging.
The step（1）The concentration of suspension is 4wt.%, and wherein mixing speed is 160-180r/min.
The step（2）In it is ultrasonically treated be that 60kHz, ultrasonic power are that 1000W, temperature are entered at 100 DEG C in frequency
OK.
The step（3）Wheat stalk is crushed to 300-400 mesh, and wherein mixing speed is 200-230r/min.
The present invention has following beneficial effect：The present invention with modified sodium-based montmorillonite be nucleator, the compatibility with PET resin
And good dispersion, sodium-based montmorillonite is carried out into orgnic-intercalation modification by cation exchange, cause the broken of montmorillonite layered structure
It is bad, and then nano level particle is dissociated into, now negative electrical charge superfluous in layer forms certain forms with the macromolecular end of the chain of PET
Ionic bond, hinders the motion of PET molecule segments, reduces the growth free degree of crystal, and growth course is obstructed, and crystallite dimension also compares
It is larger, so as to reduce the fusing point of composite, improve the barrier of composite；Addition nano titanium oxide, improves
The Durability of antimicrobial effect of composite and then improve the antiseptic property of packing material and extend the shelf-life of product；The present invention is by glass fibers
Dimension is added in raw material after nano-calcium carbonate graft modification, improves the mechanical performance and compressive property of composite, and this is answered
Condensation material crystalline rate is fast, and to gas, the good barrier property of liquid, high mechanical strength, compressive property is excellent, and rigid obdurability is big and saturating
It is bright, nontoxic, tasteless, it is non-breakable, it is fully applicable to the packaging of the liquid such as tea beverage, oil product and carbonated beverage.
