Description
Technical field
The present invention relates to PVC material technical field, more particularly to a kind of shape memory PVC material of high fire-retardance and its preparation
Method.
Background technology
China is tire production and automobile superpower, with the quick rise of domestic automobile owning amount, is generated every year a large amount of
Junked tire, how effectively to recycle these junked tires, prevent the pollution of the environment, be of great practical significance
With huge economic value.At present relatively conventional junked tire recovery method mainly there is prototype directly to utilize, burn heat, it is old
Tyre rebuilding, production reclaimed rubber, production vulcanized rubber powder etc. are several.The activity for reclaiming junked tire product is improved, strengthens it
It is the emphasis of waste tire rubber reutilization technology with the adaptability of different materials.
Shape-memory material is a kind of important functional material, and wherein high molecular polymer shape-memory material is sent out in recent years
Exhibition is swift and violent, compared with traditional function material, and polymer shape memory material has big deformation quantity, wide reply scope, easy processing, consumption
The energy low advantage of low, cost, such as has been developed for the crosslinked polyethylene with shape memory characteristic, polystyrene, poly- ammonia come
The materials such as ester, PLA, polycaprolactone, have broad application prospects.But relevant PVC shape-memory materials are rarely reported.
CN104004304A discloses a kind of PVC material with shape memory function, is crosslinked using anti-impact modifier and thermal reversion
Agent realizes PVC shape memory and repeats processing and utilization.But the mechanical property of material is still to be modified, and anti-flammability is poor.
The content of the invention
There is provided a kind of shape memory PVC material of high fire-retardance and its preparation for the defect that makes up prior art by the present invention
Method.
The present invention is achieved by the following technical solutions：
