Abstract

The invention relates to an amino-terminated polyether and belongs to the technical field of polyoxyalkylene compounds. The amino-terminated polyether includes 30-40 parts of hydroxyl-terminated polyoxypropylene diether, 20-30 parts of triethylamine, 15-20 parts of diketene, 20-30 parts of ethylenediamine, 50-80 parts of toluene, and 50-parts of xylene 80 servings. The amino-terminated polyether of the present invention can be used in the preparation of polyurea elastomer for spraying.

Description

technical field [0001] The invention relates to a polyoxyalkylene compound, more specifically, the invention relates to an amino-terminated polyether, which belongs to the technical field of polyoxyalkylene compounds. Background technique [0002] Amino-terminated polyether is a kind of molecular main chain with polyether skeleton. A polyoxyalkylene compound whose terminal is blocked with an amino group. Since Texaco Chemical Company took the lead in completing the industrial production of amino-terminated polyethers, people have conducted in-depth and extensive research on the synthesis methods and applications of this type of products. [0003] Due to the reactivity of the terminal amino group, it can interact with a variety of reactive groups, and the application of this type of products is becoming more and more extensive. At present, some of the synthesis methods of amino-terminated polyethers have been used in industrial production. The main preparation methods are ...
