Problems solved by technology

However, graphene has a high specific surface energy, and it is easy to agglomerate to form larger material aggregates, which makes it difficult to stably disperse graphene in the epoxy resin system, which will seriously affect the performance of graphene. Therefore, Need for surface modification of graphene
In the prior art, the surface hydroxylation of graphene is generally carried out first, and then modified with silane coupling agent. On the one hand, the process is complicated, and in addition, the functional groups on the surface of graphene after modification are also prone to fall off in subsequent operations, which actually works. has very limited functional groups

Abstract

The invention belongs to the field of paint preparation and in particular relates to high-performance antifouling paint. The high-performance antifouling paint comprises components of epoxy resin, graphene, a curing agent, a cosolvent and a mixed solvent. The cosolvent is compound with a molecular structure in a star shape, improves dispersion of unmodified graphene in the components of the paint, solves the problem of complex work procedures caused by pretreating and modifying the graphene and brings higher antiseptic performance and antifouling performance to the paint.

Description

technical field [0001] The invention belongs to the field of paint preparation, in particular to a high-performance antifouling paint. Background technique [0002] Biofouling is a major problem that has plagued the development of the marine shipbuilding industry for a long time; the research results show that marine fouling caused by marine organisms on the surface of the ship will increase the roughness of the hull surface, reduce the speed of the ship, increase fuel consumption, and will contribute to the future development of the hull. Pollution and cleaning cause a lot of capital and manpower consumption. According to statistics, biofouling will increase the fuel consumption of ships by 40%; in addition, the annual economic loss caused by corrosion in my country is at least 90 billion yuan, and marine corrosion accounts for more than 30%. It accounts for about 30% of the total corrosion of marine materials. If the problem of hull pollution can be solved or reduced, it ...
