Description
Technical field
The present invention relates to a kind of medical macromolecular materials, more particularly to a kind of macromolecule thermoplastic material.
Background technology
Current market sales of low temperature thermo-plastic planking is generally made by polycaprolactone for main material.Polycaprolactone melts
Only 60 DEG C of point, there is certain intensity below 60 DEG C, and the then fast softening into 60 DEG C or more water-baths, is taken out from water-bath
Temperature can be rapidly decreased to 45 DEG C or so and continue that soft state is kept not damage patient skin for moulding afterwards, because
This is very suitable for being used as fixed material.But polycaprolactone itself softens too fast, heating at 60 DEG C or more there is also some defects
Time is slightly long can be sagging due to gravity or even to cannot keep shape, misoperation itself may bond together and can not
It uses.In addition, the fixation that intensity under its room temperature is suitable for finger either upper limb is still slightly inadequate for lower limb or trunk,
A certain distance has been compared with gypsum.Finally, polycaprolactone is special high molecular material, and price is high at present, therefore is made
Low temperature thermoplastic plate it is also expensive.
The content of the invention
In view of the defects and deficiencies of the prior art, the present invention intends to provide a kind of low-temp thermoplastic materials, and intensity is more
Greatly, good fixing effect；Cost reduction helps to promote the product；There is some strength, easy to operate after activation.
