Abstract

The invention discloses a method for preparing a carbon dioxide-based polyurea polymer material, which belongs to the technical field of polymer material preparation. The problem that the performance of the carbon dioxide-based polyurea cannot meet the requirements in the prior art is solved, and the application range of the carbon dioxide-based polyurea is widened. In the preparation method, polymerize amino-terminated polyurea oligomers with chain extenders, epoxy resins, alkyd resins, phenolic resins, urea-formaldehyde resins or other active end-group oligomers to obtain carbon dioxide-based polyurea polymer materials; The structural formula of the amino-terminated polyurea oligomer used is shown in formula I. The preparation method is environmentally friendly, pollution-free, simple in process, good in atom economy, and wide in application range. Polymer materials with different properties can be prepared by further reacting amino-terminated polyurea oligomers with different chemical structures with different substrates. , for a variety of purposes.

Description

technical field

[0001] The invention relates to a method for preparing a carbon dioxide-based polyurea polymer material, and belongs to the technical field of polymer material preparation. Background technique

[0002] Carbon dioxide-based polyurea, which has good mechanical properties, thermal reactivity and chemical resistance, has been extensively studied in recent years.

[0003] In the prior art, the preparation method of carbon dioxide-based polyurea mainly uses organic amine and carbon dioxide as raw materials for direct preparation. As reported by Zhao Fengyu et al. (Phys.Chem.Chem.Phys., 2012, 14, 464-468), a method for preparing polyurea by a one-step method of diamine and carbon dioxide at 4-20 MPa, however, in this preparation method, due to diamine and Carbon dioxide reacts in a closed container, and the water produced by the side reaction of polyurea cannot be removed, which affects the further reaction of polyurea, resulting in low molecular weight and low pe...
