Synthesis process of polyether polyol serving as ultra-high molecular weight springback agent

Abstract

The invention provides a synthesis process of polyether polyol serving as an ultra-high molecular weight springback agent. The synthesis process is characterized by comprising the following steps: adding 80 parts by weight of phenyl anhydride polyester B503 into a kettle; and sequentially adding 50 parts by weight of sucrose, 10 parts by weight of propylene glycol, 15 parts by weight of palm oil,5 parts by weight of soybean oil and 3 parts by weight of a synthesis catalyst C-10. The synthesis process is simple and feasible in steps and good in effect, so that the synthesis process is suitablefor highly elastic materials.

Description

technical field [0001] The invention relates to the field of textile fabrics, in particular to a synthesis process of polyether polyol as an ultra-high molecular weight resilience agent. Background technique [0002] Space suit), especially the extravehicular space suit (Extar Mobility Unit, EMU), is known as the "life talisman" of astronauts. It is a comprehensive protection system made of special materials and has the characteristics of multi-level, multi-module and multi-function. . Aviation suits have evolved from generation to generation. It also showed the concept products of space suits with futuristic colors, which are used for the exploration of the moon and Mars. In addition to functions such as cold protection, shock absorption, radiation resistance, and impact resistance, space suits also need to maintain a constant and stable positive air pressure, which is mainly played by the pressure garment bladder. The mainstream structure of space suits is a multi-layer...
