Deng exploration.Space suit is in addition to the functions such as cold-proof, damping, radioresistance, stop shock, it is also necessary to continually and steadily ensures a healthy tendency
Pressure, is mainly played a role by air-tightness limiting layer (Pressure garment bladder).Space suit main flow framework is high property
Can fiber add the sandwich of specific coatings, including underwear comfort liner, heat preservation layer, ventilation/liquid cooling layer, encapsulating layer,
Thermal insulation layer and outer cover protective layer etc. form.
At present, PPG is widely used as super high molecular weight resilience agent, but is caused the defects of its preparation technology
Its modulus of elasticity stability is affected with release property.
The content of the invention
It is an object of the invention to provide a kind of synthesis technique of PPG as super high molecular weight resilience agent, with gram
Take drawbacks described above.
The technical scheme is that：
Synthesis technique of a kind of PPG as super high molecular weight resilience agent, it is characterized in that comprising the following steps：
First the parts by weight of phthalic anhydride polyester B503 80 are added in kettle, then sequentially add the parts by weight of sucrose 50, the weight of propane diols 10
Measure part, the parts by weight of palm oil 15, the parts by weight of soybean oil 5, the parts by weight of synthetic catalyst C-10 3；Stirring is then turned on to vacuumize,
Stirred 30 minutes with nitrogen displacement two to three times, being warming up to 115 DEG C if necessary.Subsequent 10-12 1400 parts by weight of addition in batches
Expoxy propane, course of reaction control temperature are no more than 125 DEG C, and reacting kettle inner pressure is no more than 0.3MPa；At 115~120 DEG C
Insulation 1 hour, it is zero or negative pressure to be absorbed into pressure；105 DEG C are cooled to, vacuumizes (vacuum is 0.08~0.1MPa) 1 hour
Remove unreacted expoxy propane and small-molecular-weight polyalcohol；The last temperature that further reduces is to 70 DEG C of dischargings.
The beneficial effects of the invention are as follows：
Synthesis technique step simple possible of the PPG of the present invention as super high molecular weight resilience agent, effect is good,
Suitable for the application of highly elastic material.
Embodiment
The invention will be further described below：
