Description
Technical field
Prepared the invention belongs to material and applied technical field, and in particular to a kind of water-soluble degradation material, preparation side
Method and printing support.
Background technology
CN1405230A discloses a kind of water-soluble, the pollution-free and i.e. plastic shaping material of fully biodegradable in a short time
Material, the material contains polyvinyl alcohol, glycerine, Diethylene Glycol, sorbierite, fiber, white carbon, ultrafine calcium, modified starch.
CN1405230A also discloses the preparation method of the material：The glycerine of 1-30 parts of addition in polyvinyl alcohol raw material, in high temperature
Lower stirring, makes it add appropriate secondary plasticizer(-iser), crosslinking agent, reinforcing agent, modifying agent, filler etc. after fully soaking；Then, exist
Blending reaction 5-50 minutes at a temperature of 25-65 DEG C, then by resulting material be added in single screw rod or double screw extruder carry out
Granulation, and can within the temperature range of 150-250 DEG C blown film, foaming.
Due to there is substantial amounts of hydroxyl in polyvinyl alcohol molecule so that have substantial amounts of hydrogen with intramolecular between polyvinyl alcohol molecule
Key is present, and is flexible molecule additionally, due to polyvinyl alcohol molecule, the interphase interaction of molecule, weave in form intricate
High barrier molecular chain structure.And the interaction force between this polymer molecule is than between general compound molecule
Van der Waals force is much bigger, wants to overcome this active force to need higher energy, so as to cause the melting temperature of polyvinyl alcohol high
Up to 220-240 DEG C, higher than its decomposition temperature (200 DEG C or so) so that polyvinyl alcohol is typically carbonized with regard to decomposing before melting,
It is hardly possible to obtain the polyvinyl alcohol of molten condition, so as to cause the processing characteristics of polyvinyl alcohol very poor, it is necessary to plasticization and modification
It can just be processed further afterwards.Although also using plasticizer glycerine in the above-mentioned methods to be plasticized polyvinyl alcohol, by
The interleaving effect that can not be destroyed between polyvinyl alcohol molecule in plasticizer glycerine, thus cannot be introduced into polyvinyl alcohol molecule
In, the mixing between them is a kind of simple physical blending, also just can not really play the plasticization to polyvinyl alcohol,
The melting temperature of polyvinyl alcohol thus can not be reduced, the molten condition of polyvinyl alcohol still can not be realized.And people in the art
Member is well known that the technique such as granulation of the prior art and its follow-up blown film, foaming is in single screw rod or twin-screw
Molten state will be at after mixture heating melting in extruder, while material is also needed to certain mobility, so
The material of molten state could extrude and be molded at the die head of extruder, but above-mentioned material can not reach molten state and
With less the mobility under molten state, blow molding or foaming can not be realized at all, because if temperature is too high, poly- second
Enol mixture has just been carbonized without melting, and if temperature is less than decomposition temperature, polyvinyl alcohol can not be melted, also
It can not be made to realize mixing truly with other components in the molten state, it is impossible to realize that granulation or the raw material being made do not have
There is plasticity, thus also can not just carry out follow-up blowfilm shaping or foaming.In summary, with public in CN 1405230A
Composition opened and preparation method thereof can only prepare casting films by the tape casting without heating melting.
