Abstract

The invention belongs to the field of high polymer materials, and particularly relates to a dendritic silane-polyamide-amine polymer as well as a preparation method and application thereof. The dendritic silane-polyamide-amine polymer is prepared by polycondensation of a monomer A, namely ethylenediamine tetrahexanoic acid, a monomer B, namely 3-(2-aminoethyl-(2-carboxyethyl)amino)propionic acid,a monomer C, namely ethylenediamine, and a monomer D, namely gamma-aminopropyl triethoxysilane. When the polymer is used as a coupling agent, compared with an existing coupling agent, by lengthening amolecular chain and increasing active functional groups of single molecules, the reaction probability is increased, the coupling effect is further improved, the coupling efficiency is high, the binding force is high, and the cohesive energy of glass fiber and inorganic filler reinforced plastics can be greatly improved after the coupling agent is used.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a dendritic silane-polyamide-amine polymer and a preparation method and application thereof. Background technique [0002] According to its structure, polymers can be divided into: linear polymers, branched polymers, star polymers, network polymers and dendrimers. Dendrimers are a class of artificially synthesized macromolecules with special structures such as nanometer size, three-dimensional structure and high symmetry. Dendrimers are monodisperse macromolecules with regularly branched tree-like morphology and three-dimensional configuration. Dendrimers are composed of a series of dendritic branches emanating from a central core, giving them a compact spherical appearance. [0003] Due to the excellent and unique structural characteristics of dendrimers, the application research of dendrimers has attracted the attention of scholars from all walks of life. At pres...
