Description
Technical field
The invention belongs to technical field of macromolecules, a kind of expanded polylactic acid resin and preparation method thereof is referred in particular to, applied
In by supercritical CO2For the expanded polylactic acid sheet material field that foaming agent, extrusion foaming are processed.
Background technology
Foamed plastics has many excellent performances such as light weight, impact strength are high, specific strength is high, sound deadener/insulator is good,
Through being widely used in the departments such as packaging, building and transport.Traditional foamed plastics such as polyethylene (PE), polypropylene (PP),
Polystyrene (PS) etc. is that, with non-renewable petroleum resources as raw material, being placed in after use in natural environment to decompose, and burn
In gas after burning treatment containing the noxious material such as substantial amounts of nitrogen, sulphur, phosphorus, halogen, severe contamination it is for the survival of mankind from
Right environment.
Novel environment-friendlymaterial material PLA (PLA), also known as polylactide, is a kind of macromolecular material of good performance, with life
Biodegradable and biocompatibility.PLA be by the natural reproducible resources such as wheat, corn, grain straw be Raw material processing
It is made, the final product of decomposition is water and carbon dioxide, will not produce pollution to environment.
Expanded polylactic acid product can apply to buffering package, disposable lunch-box, instant noodle box, pallet, hamburger box, coffee
Coffee cup etc., is the ideal material for substituting PS foamed products and pulp product.
Although PLA has mechanical strength higher, bending modulus is more than polystyrene, and flavor barrier is excellent, heat-insulated
Property it is good, but PLA fragility is larger, shock resistance is poor, be heated easily decompose, and single polylactic acid foam hair
Bubble rate is relatively low or individual blisters form is bad, and shaping is more difficult, and cost is also higher.
Melt strength is the Important Property Parameters for influenceing polymer expandable.Refer to that polymer is supported in the molten state
The ability of sole mass.Macromolecule melt intensity (MeltStrength), otherwise referred to as melt elasticity (Melt
Elasticity), it is about measuring to macromolecule melting elongational viscosity (Elongational Viscosity) in engineering, its
With high molecular molecular weight (MW), molecular weight distribution (MWD), branch chain (Branching) is how many/length etc. is relevant.Return root in fact
The knot base of a fruit is exactly to depend on degree of entanglement (the Degree of Polymer Chain Entanglement under macromolecule molten condition
At MelT), degree of entanglement is high, and melt strength is just high.So can be improved by being branched or being crosslinked (Cross-linking)
Macromolecule melt intensity.
In general, melt strength product high is relatively adapted to extrusion, and the low product of melt strength is relatively adapted to injection；It is molten
Body intensity and melt index are numerically into rightabout, that is to say, that melt strength is higher, and melt index is lower.
The difficult point of expanded polylactic acid is that its melt strength is low, is difficult to wrap bubble and send out when foaming product is prepared
Raw melt fracture simultaneously steeps and the phenomenon such as collapses.Thus how to improve the difficulty that melt strength is the excellent foaming product of processability
Point.
