The invention discloses a functional silane macromolecule polymer, a preparation method, an additive and an application thereof, and relates to the technical field of organic synthesis. In order to solve the problem that the hardness of the coating cannot meet the requirements; the preparation of the functional silane macromolecule polymer of the present invention The method includes the following steps: mixing a silane coupling agent and a solvent in proportion, adding a polymerization inhibitor and stirring evenly, and adding methanol-water-hydrochloric acid solution dropwise; after the dropping is completed, reacting at room temperature for a period of time, collecting alcohol and solvent under reduced pressure, and then adding After the solvent is heated and reacted for a period of time, the pH regulator is used to adjust to neutrality, the solvent is distilled off under reduced pressure, and the silane macromolecular polymer is obtained by filtration; It can be used in coatings and release agent systems to replace resins to further improve the hardness and salt spray resistance of composite materials. |
