Abstract

The invention belongs to the technical field of marine antifouling materials, and discloses degradable hyperbranched resin and a preparation method and application thereof. The degradable hyperbranched resin is prepared from the following components in parts by weight: 1-100 parts of a cyclic monomer, 0-60 parts of a vinyl antifouling functional monomer, 0-60 parts of a bifunctional monomer, 0-70parts of a vinyl monomer, 1-20 parts of an initiator, 0.5-10 parts of a chain transfer agent and 50-150 parts of an organic solvent. According to the invention, the bifunctional monomer and the chaintransfer agent are introduced in the process of polymerization, and a hyperbranched structure is prepared from traditional straight-chain polymer antifouling resin and is applied to the field of marine antifouling for the first time. Besides, the resin also has the same advantages of high solid content and low viscosity as a hyperbranched polymer; and the preparation method is simple and feasiblein process, low in cost and suitable for industrial production, and has good development prospects in the field of marine antifouling coatings.

Description

technical field [0001] The invention belongs to the technical field of marine antifouling materials, and in particular relates to a degradable hyperbranched resin and a preparation method and application thereof. Background technique [0002] The problem of marine biofouling will cause huge economic losses and potential safety hazards. Therefore, marine antifouling is a subject closely related to the major needs of the environment, energy, and national defense, and is of great significance. At present, the application of marine antifouling coatings is the most economical, convenient and common method to solve the problem of marine biofouling. The mainstream self-polishing resin technology is represented by polysilyl acrylate, zinc polyacrylate and copper polyacrylate resins, all of which are side chain hydrolyzed, and their performance has certain requirements on the stopping ratio and speed. In the static stage, it is difficult to achieve the ideal self-polishing effect on...
